Adaptive Method for Decreasing Over-covered Areas in Wireless Sensor Networks

Sensor networks specifications are highly dependent on the application defined for the network. In this paper we tried to achieve adaptive method for decreasing over-covered areas using a simple selection algorithm in order to cover the desired percentage using a minimum number of active sensors and thus achieving to a higher life time for the whole network. The main advantage of this sensor-based algorithm is its selections that do not need a centralized coordination and thus increase the independence of each node from the whole network. In addition the networkpsilas robustness is increased and it becomes more resistant to unpredictable problems and network can adapt itself to different situations. Another advantage of the algorithm is that it does not need any sensor to locate the geographic location of each node. This algorithm leads finally to the possibility of more application and better usage of a presented wireless sensor network.
