Masters Student Presentation:
Sensor Network: Security and Challenges

Soumyajit Manna


Wireless Sensor network is a wireless network consisting of spatially distributed autonomous devices using sensors (termed as node) to cooperatively monitor physical or environmental situations like temperature, sound, vibration, pressure, motion, pollution at different location. The initial development of Sensor Network was encouraged by the military application in battle field. Later with much development in the ideas and technology it serves many civilian applications as stated above. When we are taking about a system which servers our important need, that system needs to be secured. So the security issues come into play. There are some unique challenges associated with sensor network like limited energy, computation and communication capability, physical attack, and most important is its economic viability, traditional network security technique cannot be applied. So I have surveyed various papers and articles on security on sensor network and its overcoming technique, and I will discuss these security challenges and its way to solution and future research work.
