Efficient Surveillance System Based on Cognitive Radio

Several types of surveillance Systems are available in market, having different functions like security, life savings, and safe driving etc. Currently all available surveillance systems are based on fixed radio access technology. In our work, we evaluate the problems with fixed Radio Access Technology (RAT) based surveillance systems, and then propose a cognitive radio based surveillance system. Now a day’s cognitive radio is a symbol of intelligent networks, and lot of work on these types of networks is going on in all over the world. During our tests on fixed RAT based surveillance system, we observe that the fixed RAT based surveillance system is not capable of providing, hundred percent network availability due to signal loss, power loss, hardware theft or due to natural disasters (earth quake, floods etc). We propose a new algorithm to introduce cognition in the existing system
