Definition
• Wireless Sensor Networks(WSNs) are wireless
  networks used to monitor physical and
  environmental conditions using devices called
  “sensors”.

Motivating applications

•   Seismic Structure Response




•   Marine Micro-organisms




•   Contaminant Transport




•   Ecosystem complexity

• Along with the mentioned motivating
  applications, a wider spectrum of future
  applications include :- monitoring the highway
  traffic, pollution, wildfires, building security,
  water quality and even people’s heart rates.
• Protecting aggregated data that this system
  (WSNs) generates is very important
  considering the importance of the applications
  mentioned above.

Security Techniques in WSNs (low level)
• Key establishment and trust setup
• Secrecy and Authentication
• Robustness to communication denial of
  service
• Secure Routing
• Reliance to node capture

Discussion of a security technique
• Establishing pairwise keys for securing WSNs
  – Minimizing resource consumption of individual
    devices.

Future Potential Research
• Redundancy in WSNs
• Securing wireless communication links against
  eavesdropping, tampering, traffic analysis etc.
• Finding ways to tolerate lack of physical
  security.
