A sensor network is collection of sensing, computing, and communication elements that give an ability to observe and react to events in different environment. The environment can be the small office area or a huge industrial plant. Wireless sensor network overcome limitations of traditional wired network i.e. flexibility, can be deployed in dense area. Nodes of wireless sensor network are battery powered and frequent change of batteries is not feasible solution. Instead of frequent change of batteries it is better to go for deployment of new plant.
