   Self Configuration in autonomy aims to acheive organisational structure without human intervention. Problem
arises when new nodes are added or older ones removed as services offered by a network have to be accepted and
processed by end nodes. A self configuring secure autonomic protocol for end nodes connecting in a star topology is
proposed. Here, the procedure for transmission of control packets are described in a basic secure manner to achieve
self configuration for heterogenous networks. In addition, security mechanisms to supplement the self-configuring
behaviour are proposed.

   This research proposal suggests a novel system for parallel Bioimpedance Spectroscopy that is also portable,
without the need to use a dedicated computer system to perform the calculations and display the results, but it will
be presented in a single package that acquire data, process it and display information and results in the form of plots.
One drawback of impedance analyzers --which are used in bioimpedance spectroscopy-- is they are not portable, and
this research hopes to address that issue by designing the system on an FPGA. Another drawback this research
proposes to address is parallel signal acquisition and processing for handiling multiple test subjects, this will be done
in the FPGA which will allow the system to have a processing and acquisition capability of parallel signals. The
design will start by creating a single bioimpedance spectroscopy acquisition module, then expand it to a parallel
system of at least 2 signals. A processing unit is the designed to process data from the acquisition modules, and a
display unit is also designed to send the results in the form of plots to an attached monitor. Finally results will be
compared to an Impedance Analyzer to show how accurate it is.

   Online analytical processing (OLAP) is becoming increasingly essential technique, particularly for decision
support systems (DSS). OLAP is considered suitable technology for online analysis, comparing to its counterpart:
Online transaction processing (OLTP), due to the fact that OLAP offers an instantaneously answers to the immediate
queries that decision makers urgently need to make their decisions at some critical moments based on the latest
updates of the warehouse. However, despite its speed processing capabilities; OLAP does not achieve the Real-Time
applications’ requirements, rather, OLAP approaches the Real-Time, in other words, OLAP can achieve near Real-
Time. Our study addresses this shortcoming and attempts to propose a novel solution taking advantage of
revolutionary hardware development on two levels; namely, the multi-core processors as well as distributed systems
processing. This new approach would exploit the hardware resources optimally, and as a result; significantly
increase the processing speed.

   Interactive Multimedia (IMM) applications have observed quick growth in the world of computer and
communication technologies. Multimedia offers voice, video conferencing, graphics services at low cost with more
flexibility in a high speed Wireless Local Area Network (WLAN) that can be defined as a high speed Wireless
Campus Network (WCN). In a video or voice conversation, the direction of traffic flow over the networks defines
the participating users work either as a sender or a receiver. IMM applications need minimum data loss, high
bandwidth and throughput through the WCN. Moreover, these applications are also very sensitive to delay. During
conversation, every voice packets need to reach on time and in-order fashion from sender to receiver with least delay
over the WCN. Packets scheduling is one of the challenging issues for improving IMM transmission and it is still an
unresolved problem over WCN. This work aims to explain fundamental characteristics of IMM related to various
applications and highlights the present scheduler issues. It also highlights the proposed mechanism which can be
used to improve the real time applications especially for IMM applications over WCN.

    Peer-to-peer (P2P) is a very popular type of network communication for file sharing, where the data transfer is
faster for it does not need to pass through the services of a server to share files and data. P2P utilization can be
grouped into three main purposes, namely communication and collaboration, distributed computing, and the most
common are file/content sharing. For the time being, the successful P2P applications have been running on either the
wired or wireless Internet connection, as well as over Personal Area Network (PAN) such as Bluetooth. For a
mobile cellular device to be integrated into a P2P network system, it needs additional support in terms of energy
efficiency. The power supply for a mobile device is limited to the length of the battery lifetime, given that most of
its power will be used mainly for downloading data which usually consumes quite a long time. Formulating a way
that the P2P activities can be done with high energy efficiency will be the main focus of this research. With IEEE
802.15.4 is considered as today’s one of the top growing wireless protocol, the research focuses on introducing
ZigBee standard into the mobile P2P environment, where the main goal is to develop the platform for file
transferring or sharing through P2P communication. The project will involve only mobile devices with Android
platforms, focusing more on Android 4.0 and beyond.

   Rain induced attenuation become a main contribution of decrease in performance of received signal in earth-
space communication links due to heavy rainfall rate throughout the year particularly in the tropical region.
RazakSat is remote sensing satellite that transmits and receives two types of range frequencies which are X-band
and S-band. The X-band frequency is conventionally set aside for military and government organizations. The
attributes of X-band satellite communication hardware are expected to be designed specifically for military
operations. The possible margin of power received should be incorporate to ensure communication system
continuity and reliability. This rain induced attenuation has been analyses based on the measurements of 3 years
(2009-2011) S-band and X-band data from Malaysia RazakSat’s satellite. The lower frequency such as 3 GHz (S-
band) is use to quantify the X-band frequency by using frequency scaling equation from different models.

   Satellite communications systems are moving towards greater capacity. Millimeter wave offers a large bandwidth
allocation, required small antenna size and should be experiencing a less congested spectrum environment.
Nonetheless, rain fade is a threat to the satellite communication links; especially in tropical region due to the severe
hydrometer effects. These are the factor that typically limiting the implementation or use of higher frequencies for
satellite communications in this region. Time diversity is a promising mitigation technique to countermeasure such
impairments, as the techniques does not require extensive auxiliaries equipment as it will only be using single
antenna. This research focused on time-diversity mitigation technique which involves a process of retransmission of
signals to obtain the required signal gain for better output signal. The study offered a mathematical model which
enables the usage of V-band frequency in tropical regions. Preliminary analyses include the time series generation
for the rain events and annual cumulative distributions.Mathematical model for time diversity gain as a function of
delay is obtained in terms of alpha and beta coefficients; which then portrayed in time diversity delay as a function
of time delay curve. The recovery strategy and its associated equations had being established to reflect the memory
capacity requirement at the receiver.

   Long term evolution LTE is a standard for wireless data communications technology and an evolution of the
GSM/UMTS standards. The goal of LTE was to increase the capacity and speed of wireless data networks using
new DSP (digital signal processing) techniques and modulations that were developed around the turn of the
millennium. A further goal was the redesign and simplification of the network architecture to an IP-based system
with significantly reduced transfer latency compared to the 3G architecture. The LTE employs OFDM at the
downlink terminal and SC-OFDMA at the uplink which both suffers from high peak to average power ratio PAPR.
This research encompasses a modified algorithm which effectively reduces high PAPR at the downlink terminal.
The based model was cross antenna rotation and inversion CARI. The modifications applied to the CARI which led
to obtain less complex scheme in circuitry and more effective PAPR reduction performance also. As a result, the
modified scheme has better spectral efficiency and bit error rate

spectrum (DSSS) principle is employed as a data modulation and transmission technique. An Avalanche UWB pulse
generator circuit is added into the spread spectrum transmitter for generating nanosecond pulses. The circuit is
achieved to generate a kind of UWB pulses whose the best pulse width is 0.91ns and pulse amplitude is 5.72V in
simulation mode. The spectral density of the pulses satisfies the specification of FCC mask defined. In fact, the
PRNG pass the NIST Test Suite randomness tests. With the feature such as simple structure, reliable and high speed
performance as well as low cost this circuit system is applicable to UWB wireless communication system.

   Functional Electrical Stimulation (FES) is a method of artificially stimulating muscles or nerves in order to result
in contraction or relaxation of muscles. Many studies have shown that FES system has helped patients to live a
better lives especially those who are suffering from physical mobility. Unfortunately, one of the main limitations of
an FES system besides of its high cost is largely due to muscle fatigue. Muscle fatigue will affect the training
duration which could delay patients’ recovery rate. In this paper, we analyzed the occurrence of this fatigue
phenomenon in terms of stimulator parameters such as amplitude, frequency, pulse width and pulse shape. The
objective of this investigation is to identify other key features of the FES system parameters in order to prolong the
training duration among patients. The experiment has been done on a healthy person for the duration of one minute
and later the muscles response will be observed. Resultant muscle response is recorded as force using force resistive
sensor. The experimental results show muscles will get fatigue at a different rate as the frequency increases. The
experiment also shows that the duty cycle is reciprocal to the resultant force.

   Nowadays, Bluetooth technology is widely used by organizations and individuals to provide wireless personal
area network (WPAN). It is a short-distance wireless connection specially designed to support portable and mobile
computing devices. However, there are serious security challenges associated with WPANs due to the security
requirements of Bluetooth connection. The conventional authentication algorithm in Bluetooth connection uses a
PIN value of only four digits which can be easily guessed by attackers. It is also vulnerable to man-in-the middle
attack where an attacker impersonates a legitimate user. This study suggests a new algorithm that combines RSA
algorithm and SHA-256 Hash function to overcome the security challenges related to Bluetooth authentication.

   In this research, a planar wideband microstrip patch antenna for passive radio frequency identification (RFID) tag
is proposed. To enable universal operation by covering the operating frequency of ultra-high frequency (UHF) RFID
frequency band from 860 MHz to 960 MHz, two C-shaped resonating patches are employed. Both of the patches are
inductively coupled fed by a rectangular loop feeding network for complex impedance matching with the referenced
microchip impedance. The proposed antenna is designed for tagging metallic objects. To simplify the fabrication
process and to reduce cost, a planar antenna structure is chosen over multi or cross layered configuration. The
simulation and measurement results show impedance bandwidth of 159 MHz and 155 MHz (Return loss ≥ 3 dB)
respectively when mounted on metal plate.

    The application of filters and resonant circuits are extensive, particularly in signals acquisition for signal
processing, communications systems, and control systems. Among those application areas, there are cases where
active filter is more suitable than passive filter —especially if gain is desired and/or cost is of significant
consideration. The main purpose of this research is to study the performance of two low-Q Low Frequency active
filter topologies, namely Sallen Key and Multiple Feedback (MFB). It was done through analytical mean and circuit
simulation using PSpice software. In this study, the performance of these topologies when get connected to design

   Abstract. Inductive sensing technique is used for detection using speed calculation. The inductive loop has an
inner turn fitted within an outer turn, making a total inductance value 60µH. This loop is made to be shown with
balanced response using three capacitance values of 0.068µF each when a sinusoidal voltage source of 5V peak-to-
peak is applied. The variation of the relative permeability of the inductance of the inductive loop (ΔL) results in a
variation of the overall inductance value (L+ΔL), that causes the output signal to change in term amplitude for

   Recent developments have shown that the use of buried electronic devices or body implants has been becoming
prevalent. Such low power devices are being powered up through non-contact means utilizing inductive coupling
from external powering source. Inductive coupling not only solves the issue of energy availability but helps
collecting the sensed data that can be archived or used for subsequent monitoring purposes. This paper analyses the
performance of two-port and three-port inductive links in terms of power sent, power received and power transfer
efficiency. All the above mentioned parameters have been plotted using analytical approach and obtaining
simulation where required. The effect of mutual coupling has been studied in detail for both systems and
demonstrated by plotting the power transfer efficiency for different values of the coefficient of coupling (k) using
MATLAB. Results show that power transfer efficiency depends highly upon the value of k.

   Since decades, commercially available semiconductor diodes are being employed as radiation detectors (solid-
state detectors) due to its capability to detect charge carriers generated in its energy band structure. Among possible
semiconductor materials for both ionizing and non-ionizing detector applications are GaAs, GaN and Si. Samples of
GaAs, GaN on SiC , and Si p-i-n optoelectronics diodes were exposed to thermal neutron for 5 minutes of equivalent
neutron dose with fluxes up to 10^12neutron/cm^2.s. A comparative analysis based on the forward-bias and reverse-
bias current-voltage characteristics of each material after irradiation process are investigated. After 5 minutes of
neutron exposure in rotary rack system, the silicon p-i-n diode was permanently damaged. The GaAs forward and
reverse bias leakage current increases after irradiation while the GaN diode shows no significant changes under
similar process.

   The acquisition of Surface Electromyography (SEMG) signals is used for many applications including the
diagnosis of neuromuscular diseases, and prosthesis control. The diagnostic quality of the SEMG signal is highly
dependent on the conditioning circuit of the SEMG acquisition system. This poster presents the design of an SEMG
conditioning circuit that can guarantee to collect high quality signal with high SNR such that it is immune to
environmental noise. The conditioning circuit consists of four stages; consisting of an instrumentation amplifier that
is used with a gain of around 250; 4th order band pass filter in the 20-500Hz frequency range as the two initial
stages. The third stage is an amplifier with adjustable gain using a variable resistance; the gain could be changed
from 1000 to 50000. In the final stage the signal is translated to meet the input requirements of data acquisition
device or the ADC. Acquisition of accurate signals allows it to be analyzed for extracting the required characteristic
features for medical and clinical applications. According to the experimental results, the value of SNR for collected
signal is 52.4 dB which is higher than the commercial system, the power spectrum density (PSD) graph is also
presented and it shows that the filter has eliminated the noise below 20 Hz.

    Quartz crystal oscillators are crucial clock sources in consumer, commercial, industrial and military products for
many years due to their high Q and temperature stable properties. Crystal oscillator can be found in almost all
portable electronic equipment around us. For example in GSM mobile phone, oscillator is used as frequency control
components for transmission and receiving filtering between antenna and transceiver chips. This research focuses on
developing a CMOS operational amplifier (op-amp) for quartz resonators operating in the 10 MHz. Two-stage
CMOS op-amp is chosen to integrate with quartz resonator. Two-stage CMOS op-amp consist of two stages. The
first stage provides a high gain whereas the second stage provides large swing. Each stage can be designed with
various amplifier topologies. For real implementation, the two-stage CMOS op-amp will be simulated with 10 Mhz
resonator. The two-stage CMOS oscillator achieves a gain of 13.09 dB at VDD of 3.3 V and VSS of -3.3 V with the
phase noise -195.5 dBc/Hz. The oscillator satisfied Barkhausen criteria of oscillation. The oscillator is simulated
using Cadence.

   In this poster, an electromechanical Pedal Power Energy Harvester is designed to harness the vibrational power
from road track deflection due to cars, which converts the kinetic energy of vehicles into an electrical power for
battery charging. The resulting energy may be used for small load applications such as in emergency lights. Whereas
typical existing vibration energy harvester is built for low power applications, the proposed energy harvester will be
designed for higher power applications. To achieve this goal we present new mechanism, in this system irregular
bidirectional linear vibration are transformed into regulated unidirectional rotational motion, which means that the
motion mechanism includes bidirectional to unidirectional conversion and flywheel speed regulation. It bears some
advantages like improved reliability, efficiency, and quality of output power. An analytical model relating input
force applied to the output energy generated which is then measured through non-contact means using inductive
coupling approach. The energy plots versus force applied to flywheel will show the results obtained so far in this
work.

   The fast growing of the Internet applications and the need of the continuous ongoing connection brought new
challenges for researchers to provide new solutions those guarantee the Internet access for mobile hosts and
networks. The globally reachable, Home-Agent based, and infrastructure Network Mobility (NEMO) and the local,
multi-hop, and infrastructure-less Mobile Ad hoc Network (MANET) developed by Internet Engineering Task Force
(IETF) are supporting different topologies of the mobile networks. A new architecture was proposed to deal with the
route optimization and inefficiency of the Nested NEMOs as well as the global connectivity issues of MANET by
combining both topologies to obtain Mobile Ad Hoc NEMO (MANEMO). However, the integration of NEMO and
MANET introduces many challenges such as the network loops, sub-optimal route, redundant tunnel problem,
absence of communication without Home Agent reachability, and exit router selection when multiple Exit Routers
to the Internet exist. This research aims to propose a scheme that addresses network loops, ensures load balancing
and selects the gateway which improves the performance and the robustness of the network regardless of routing
protocol used. This can be achieved by extending the Neighbor Discovery Protocol (NDP) used by Mobile IPv6.
Every MR will receive the information about all the Internet gateways in the network and select the gateway based
on multiple criteria: the gateway’s queue length, the number of nodes registered at that gateway, and the hop count
between the gateway and the MR. The routing of packets in the MANEMO is proposed to be based on tree structure
to achieve scalability. This scheme is expected to reduce control packet overhead, packet transmission delay, and
handoff latency. The evaluation techniques to be used are simulation and mathematical analysis. The simulation tool
which will be used is OPNET Modeler 14.0 then the results will be validated by mathematical analysis to
benchmark with the standard NEMO BS.

   Abstract— The study involving comparison between radar derived attenuation using an S-band meteorological
radar and measured signal of RazakSAT’s X-band and S-band satellite link. The radar data employed was attained
from the Malaysian Meteorological Department’s (MMD) terminal Doppler weather radar installed strategically in
the vicinity of Kuala Lumpur International Airport (KLIA). The X-band (8 GHz) and S-band satellite-Earth signals
of Malaysian RazatSat’s collected at the National Space Agency (NSA) space center in Banting, Selangor have been
analyzed and studied. The vertical polarization S-band radar reflectivity information was used to calculate the likely
rain attenuation along the RazakSAT satellite propagation paths. This was carried out by first converting the radar
reflectivity values into rainfall rate using the established Z-R relations of Marshall-Palmer equation and, afterwards,
by evaluating the slant path attenuation through the assimilation of the specific rain attenuation derived at the
rainfall rate.

monitoring continuous human activities in health care centres due to the increasing number of elderly population
and the limited availability of qualified staffs for nursing homes there is a high market demand for health care
monitoring system. Inductive Intelligent Sensor (IIS) has been proposed as a novel human monitoring system. The
system proposed senses the presence of human beings using electromagnetic field by making use of basic inductive

    The analysis of time varying frequencies are typically performed by short time Fourier transform, (STFT) and a
time-frequency distribution (TFD). Conventionally, STFT is method of choice, where , the signal is separated into
small lengths to fit a sliding window, which length, must be shortest possible to assume local stationary within the
window. Since the length of the window affects both the time and the frequency resolution in an opposite manner,
i.e. the short window length yields good time resolution but poor frequency resolution and vice versa. Good time
resolution and frequency resolution cannot be obtained simultaneously. The STFT also found unable to track quick
changes in the signal’s amplitude While the other method, TFD although mathematically complex, it yields higher
resolution for a given length of a signal but suffers severely from artifacts nor limited by uncertainty principle and
unable to get sharp resolution in both frequency and time domain. The parametric methods ( AR and ARMA ), in
form of rational system transfer, have been successfully applied to solve various issues in human endeavour. Their
usage for the modern spectral estimation of biomedical signals has been thoroughly studied and well documented as
they yields high resolution for short and non-stationary signals. Despite the structure gives a good parsimonious
representation if signals, however, it suffers from major drawback, which is estimation of modal parameters. A
number of model based methods have been developed and researched to improve spectral estimation under variety
of special conditions with too many assumptions, constraints and huge computation. Hence, improvements for time
varying parameter based method are necessary for broader clinical applications to estimating accurate model
parameters and to track dynamics of biomedical signals. In this thesis, a novel hybrid ANN based technique to
estimate and track the time series representation has been proposed and its mathematical model has been developed.
A time varying coefficients to be estimated from sum of selected basic function. A basic function of DCT is capable
to track fast spikes and permits lower expansion dimension, resulting in small value of expansion parameter’s model
order and thus reduces the complexity in computation. The representation of TV AR into sum of basic function
converts the TV parameters into TIV parameters and stationary is assumed. The identification of time varying
coefficients and the determination of model order are proposed to be addressed by Artificial Neural Network and
Genetic Algorithm. ANN is employed as 2 layer network , due to its superior performance of in system
identification and prediction due to its nature of training and learning. The well known BP algorithm is proposed to
train the ANN to find proper weights to minimize the energy. GA is proposed to be adopted due to the global search
capability and speed. A stopping criteria of MDL is proposed. Taking the advantage of optimization capability of
genetic algorithm to determine the model orders combined with the performance of ANN , the time series
representation is able to produce high quality resolution and with faster computation time.

   The novel femtocell (HeNodeB) in Heterogeneous network (HetNet) for LTE-Advanced (LTE-A) set-up will
allow Malaysian wireless telecommunication operators (Maxis, Celcom, Digi, U-Mobile, P1, YTL and etc2.) to
extend connectivity coverage where access would otherwise be limited or unavailable, particularly indoors of large
building complexes. For the Malaysian service providers, the main attractions of HeNodeB usage are the
improvements to both coverage and capacity. The operators can provide a better service to end-users in turn reduce
much of the agitations and complaints. There will be opportunity for new services at reduced cost. In addition, the
operator not only benefits from the improved capacity and coverage but also can reduce both capital expenditure and
operating expense i.e. alternative to brand new base station or macrocell installation. Interference is a key issue
associated with HeNodeB development. The interference between HeNodeB-to-macrocell and HeNodeB-to-
HeNodeB is the most critical challenges for femtocell deployment in HetNets. In this research, a self-organizing

   NEMO BSP is an upgraded addition to Mobile IPv6 (MIPv6). As MIPv6 and its enhancements (i.e. FHMIPv6)
possess some limitations like higher handoff latency, packet loss, so NEMO BSP also faces all these shortcomings
by inheritance. Network Mobility (NEMO) is involved to handle the movement of Mobile Router (MR) and it’s
Mobile Network Nodes (MNNs) during handoff. Hence it is essential to upgrade the performance of mobility
management protocol to obtain continuous session connectivity with lower delay and packet loss in NEMO
environment. The completion of handoff process in NEMO BSP usually takes longer period since MR needs to
register its single primary care of address (CoA) with home network that may cause performance degradation of the
applications running on Mobile Network Nodes. Hence, providing continuous Internet connection without any
interruption through applying multihoming technique and route optimization mechanism in NEMO are becoming
the centre of attention to the current researchers. In this research, we propose a development of mobility
management scheme to achieve a seamless handoff by integrating host based mobility protocol in NEMO with
performance evaluation.

   Future direction of satellite communication systems is towards utilizing higher and higher frequencies, such as Ka
and V-bands in near future Rain-induced attenuation is the major issue at frequencies above 10 GHz, more
especially in tropical regions which face heavy rainfall with different characteristics. To encounter rain attenuation
problem on earth satellite links, implementation of Fade Mitigation Techniques is necessary at high frequencies.
Scarcity of measured data at higher frequencies is also an issue in tropics. Therefore, this research looks forward to
find a suitable solution for these problems in tropical areas using measured rain rate time series and available

   The use of CGA algorithms is a very attractive option for securing binding update (BU) messages in Mobile IPv6
networks. However, the implementation cost of some of the operations (e.g. CGA signature generation) is
significant enough to cause concern that these operations could be used to launch denial of service attacks on low-
end mobile nodes. This work investigates the possibility of replacing the use of RSA in CGA algorithms with the
Merkle Signature Scheme (MSS). The implementation developed in C and run on an actual N900 node shows that
using MSS reduces the computationally expensive key generation time by almost 20 times and the CGA Signature
Generation time by almost half.

   Network mobility basic support (NEMO BS) protocol is an entire network, roaming as a unit which changes its
point of attachment to the Internet and consequently its reachability in the network topology. NEMO BS doesn’t
provide QoS guarantees to its users same as traditional Internet IP and Mobile IPv6 as well. Typically, all the users
will have same level of services without considering about their application requirements. This poses a problem to
real-time applications that required QoS guarantees. To gain more effective control of the network, incorporated

applications delivery at low deployment cost when internetwork with existing Internet, cellular and sensor networks.
New protocols such as routing, security traffic engineering and error control are continually being designed,
simulated and evaluated for these applications. Network research community usually employs topology generators
in the design, analysis and evaluation of network protocols, because they provide representation of scenarios of
interactions among network components for studying the characteristics and performance tuning which accompanies
the development of protocols. However, the architectural characteristics of Wireless Mesh Networks are not
adequately modelled in the existing synthetic topology generators initiated on pure graph properties. This work
therefore proposes the design of topology generation tool based on architectural model of wireless multihop
networks. Furthermore, the results of evaluation of the proposed topology generator are presented. Thus models of
real characteristics of physical network produces acceptable relevance and validity of simulation results, hence the
realisation of objectives of computer network researches.

   In recent years, Cognitive Radio (CR) technology has largely attracted significant studies and research. Cognitive
Radio Ad Hoc Network (CRAHN) is an emerging self-organized, multi-hop, wireless network which allows
unlicensed users to opportunistically access available licensed spectrum bands for data communication under an
intelligent and cautious manner. However, in CRAHNs, a lot of failures can easily occur during data transmission
caused by PU (Primary User) activity, topology change, node fault, or link degradation. In this poster, an attempt has
been made to evaluate the performance of the Dual Diversity Cognitive Ad-hoc Routing Protocol (D2CARP) in
CRAHNs under different path failure rate. The simulations are carried out using the NS-2 simulator. The protocol
performance is evaluated with respect to performance metrics like average throughput, packet loss, average end-to-
end delay and average jitter. From the simulation results, the protocol performance is greatly affected when the path
failure rate is high, leading to major service outages.

   Femtocells are a promising technology to increase the capacity, efficiency and the coverage of the cellular
networks. Due to their low cost, they can be deployed as consumer equipment, reducing the capital load and
operating expenses of the host network. Their high performance can be gained at no loss of service to the customer
owing to the improved link budgets and improved services. However, for these apparent benefits to translate into
real advantage for network operator and consumer alike, several challenging issues must be addressed first and
resolved before this touted technology becomes a reality. Interference mitigation and management is considered a
make or break for this promising technology inducing, in the process, feverish research efforts on the topic recently.
There are two types of interference in femtocell networks; the first one is interference between the femtocell and the
macrocell, that is called cross-layer interference, and the other one is the interference between the femtocell and
others femtocells deployed within the coverage area of the main macrocell. This type of interference is called co-
layer interference. Therefore, interference management is necessary and a practical interference mitigation method is
a must. In order to model the interference, indoor propagation is required. Most of the available models are for long
range communication like macro and micro cellular networks. Models for femtocell networks where the effects of
walls and floors are appeared are necessary. In this poster eight different models of indoor propagation were studied
and compared with measured data. Measurements were conducted in three story building. Four different scenarios
with different numbers of penetrated walls and floors were considered. The results were statistical analysed by
calculating the average error and the error standard deviation.

   DC-DC converters are designed to supply voltage in desired range. These desired ranges varies depending upon
the requirement of input voltage of electronic appliances. However to stabilize the output of renewable energy
sources a control approach is required, because the output from these sources is not at constant level and it changes
with the changes up and down in environment and surrounding conditions. In this Project a control strategy by
collaborating Buck and Boost DC-DC converter is proposed to stabilize the output of the renewable energy sources
in desired range. This range is controllable and can be changed depending upon the requirement

    Cloud computing is a channel to obtain a highly scalable – technology enabled services over the internet on pay
per-use basis. The selections of services render in the cloud range from Software- as- a- Services, Platform- as- a-
Service and Infrastructure –as- a Service and it can be hosted in a private or public cloud. Regardless of the
architecture, the concept of cloud computing service is that customer’s data (which can be individual, organization
or enterprise) is process remotely and reside in unknown machines that users do not own or operate. Although
widely acknowledged and accepted in business for its convenience and efficiency research on cloud computing is
still at infancy. Many existing issues have not been fully addressed and one of the fundamental security concerns is
information leakage. Information leakage is defined as a breach of confidentiality of information, typically
originating from staff inside an organization and usually resulting in internal information being disclosed into the
public domain”. Information leakage can be caused by negligence or intentional sabotage and in many cases it goes
unreported due to fear of loss of confidence and regulatory penalties. The impact of information leakage can put the
organizational networks and system at risk of malware, leading to lawsuit for copyright and defamation and
indirectly can tarnish the organizational reputation and jeopardize the organizational future revenue. There are two
approaches that have been explored to address the information leakage issue, reactive or proactive. Reactive
approach is detecting any leakage after the incidents and the organization will assess and conduct necessary action to
remedy and reduce the lost based on the seriousness of the case. One of the techniques which widely applied is the
Honeypots, however, this approach is ineffective and vulnerable in the context of cloud computing environment due
to the subtleties of how the physical resources can be transparently shared. Proactive approach is proposed to
overcome the aforementioned issues. This approach is also called an Insider threat prediction which is identification
and detection of any potential attempt to compromise the information privacy and security through leakage prior to
the incidents and alert the administrator to minimize the lost and risk. This presentation will report the research gaps
and work in progress on the Insider Threat Prediction Model to safeguard the information security in the context of
cloud computing environment.

   This poster presents a novel approach of an inductive sensor based on the basic principle of producing
inductances in proportion to sea saw oscillations. The work centers on design and development of differential
inductive transducer for accurate position measurement. Basically, it’s a displacement-position sensor which can be
used for tiny deflection measurement in oscillatory motion. Using an inductive coil sensor in a differential manner, a
physical parameter is translated into a signal with proportionate output frequency change. The results shown can be
used for characterizing the materials and hence sensor with high sensitivity, linearity and responsiveness in harsh
environmental condition is obtained. The experimentation is done to provide a real time implementation and
processing. The frequency properties for paramagnetic and ferromagnetic materials are obtained, providing a
realization of how system disturbances and oscillation have been translated into useful wireless electrical pulses.
The detection and optimization of the oscillation produced in milli and micro deflection deviation has been
implemented to verify its obtained derivations and simulations.

   Boolean functions have been of great interest in many fields of engineering, science, and mathematics. In the
context of cryptography, they play a central role in the design and application of information protection methods.
The strength of cryptographic systems against any potential attack is determined solely by several criteria which the
cryptographic functions should meet. These criteria can be analyzed and measured through the aid of certain specific
important tools or methods of approach. In this research work, we take the help of an alternative tool for the analysis
and design of cryptographic Boolean functions. We employ Haar spectral transform as an alternative method of
approach to analyze the cryptographic functions and measure their cryptographic strength. The focus of this work is
based on the analogy between the Walsh and the Haar spectral transforms. We first present a brief overview of the
cryptographic functions, cryptographic systems, and the current tools used for the task under context. Then we
introduce the Haar spectral method and explore concisely its progress and significance in representing Boolean
functions. The next step in this presentation is the initial results for the analysis phase of the research work. In the
process we look at some general properties of cryptographic functions that include Hamming weight, distance, and
balanced criterion. We present their general representation using the Haar transform, as well as the Haar-
representation for the general class of Bent functions. For the Bent functions, we explore the representation in
connection to the Walsh transform and the Autocorrelation function. In doing so, we present the Walsh transform in
different orderings of its functions. Finally, we present as a conclusion, a discussion for the status of the ongoing
research work at hand including the expectation for the future work.

   Network Mobility (NEMO) is an extension of Mobile IPv6, which aims to provide efficient network that roams
as one unit without interruption. Nevertheless, NEMO still suffers from some limitations, especially when the level
of nesting increases. This research proposed a novel route optimization using hierarchical structure with Binding
Update Tree (BUT), to overcome the drawbacks of NEMO such as pinball routing problem and binding update
storm, and achieve seamless handoff.

   This poster presents randomness test in terms of uniformity and the avalanche effect test for the Bit Distribution,
Triple S-AES, and CFB-AES of one-to-many reversible mapping mechanism. Randomness test of a one-to-many
reversible mapping between user space and IPv6 address space developed to improve IPv6 address management in
an enterprise wireless local area network. The result is shown that all mechanisms (Bit distribution, Triple S-AES,
and CFB-AES) have passed the uniformity test. However, only the mechanism which used the CFB-AES has passed
the avalanche effect test. The Interface IDs which have been generated using CFB-AES can be considered to be
randomly generated with a confidence level of 99%. This makes it difficult for eavesdroppers to identify the owners
of the IPv6 addresses and thus respects user privacy.
