In this paper, the authors propose a different approach for efficiently conserving energy in wireless sensor networks. Their approach towards energy consuming in sensor networks is fully distributed to consume very low energy for finding the path along with data transmission. They use two protocols LEACH and ELEACH-M to find the route for data transmission and make its performance by comparing the route discovery of those two protocols. Bayesian inference is used to inference the missing data from the nodes that were not active during each sensing.
