ENERGY EFFICIENT MAXIMUM LIFETIME ROUTING FOR WIRELESS SENSOR NETWORK

In wireless sensor network, sensors or nodes are generally battery powereddevices. These nodes have limited amount of initial energy that are consumed at different rates, depending on the power level. For maximizing the lifetime of these nodes m ost routing algorithm in wireless sensor networks uses the energy efficient path. These energy efficient routing algorithms select a best path for data transmission and consume less energy. But a single best path puts extra load to a specific node causing lower lifetime. This paper proposes an energy efficient maximum lifetimerouting algorithm. It is based on a greedy heuristic technique to maximize lifetime of the system. For achieving maximum system lifetime proposed algorithm uses the energy cost of links for constructing energy efficient path. The Simulation results demonstrate that EEMLR algorithm significantly minimizes energy consumption of each node and balanced the energy for entire network as well as extend the network lifetime .
