An Energy-Efficient Algorithm for Maximum Lifetime and Minimum Routing in Wireless Sensor Networks

Wireless sensor networks (WSNs) have received more and more attention due to the limited energy of battery-powered nodes, but rarely consider the maximum lifetime and the shortest path at the same time. In this paper, we present an energy-efficient algorithm for maximum lifetime and minimum routing (EE-MLMR) in wireless sensor networks. EE-MLMR improves energy utility by changing the activity of wireless communication module of sensor nodes, energy model and state transition of sensor nodes. EE-MLMR employs the minimum angle of source node and goal node to prolong network lifetime. Simulation results show that EE-MLMR performs better than DD and EER algorithm for wireless sensor network with high-density deployment and low traffic.
