IPng based mobility management for ad hoc robot networks
   1. Introduction

While the present IP version in IPv4, due to its limitations, work on the next generation
IP (IPng) or IPv6 is being pursued by the ITEF. Am important aspect of IPv6 is that, the
mobility management is being studied and built up in it from the beginning. Performance
characterisation of mobility management schemes are studied extensively for example in
[1].

Autonomous and semi-autonomous multi-robot systems form a wireless adhoc network
to accomplish a task [2]. A multi-hop network that is also self-organizing may ideally suit
for such a network. The dynamics of the robots may have both controlled or completely
uncontrolled dynamics. This environment is ideally suited for a wireless mesh network
(WMN) [3]. The project proposes to study an IPv6 based mesh network for mobile robot
networking.

   2. Rationale of this project

An adhoc mobile robot network carries important characteristics for a real-time
communication, for example, VoIP over a network in the sense that, communications are
real-time or near real-time, two-way (full-duplex or half-duplex), and should be done
within a tight quality of services (QoS) bounds. This has also the characteristics of
network mobility (NEMO) [4], with self-configuration. Further, session setup,
maintenance and teardown will be needed similar to that in a VoIP session [5]. The main
difference would however be in the QoS requirements, the controlled movement and in
the mobility management. This project envisages in exploring these facets of an
autonomous mobile robot adhoc network, in a WMN set-up.

   3. Methodology

The envisaged research project envisages how the WMN concepts will fit in to an adhoc
mobile robot network, either in autonomous or in semi-autonomous mode. This work will
be mainly theoretical but some experimental aspects will be involved. The student will
start with reading and understanding the underlying literatures in IPng, QoS, WMN and
mobility management. Next, analytical or simulation models for robot networks, first in
one-dimensional case and secondly, in a two-dimensional case in the context of a WMN
will be developed. Simulation environments for example, OMNET++, NS-2 or Matlab
will be used. An experimental setup with Khepera or other robots will also be tried in
parallel.
     4. Expected outcome

     This work is at the cutting edge of wireless technology and any good result will be
     confidently published at top quality journals and conferences. It is expected that, 1-3
     top journal and 3-5 conference paper will be published from this project.

     5. Desirable qualifications

a)    A first class Masters degree from a reputed University/Institute in
      communications/telecommunication engineering or in Computer Science or in
      related area.
b)    Knowledge in mathematical tools applied in wireless technology research
      (particularly, linear algebra, probability theory and stochastic process).
c)    Knowledge of Matlab and C++

     6. Software/hardware requirements

General computational facility, MATLAB, OMNET++, NS-2, mobile robots, Crossbow
sensor network kit etc. (available in the laboratory).
