Lifetime maximisation algorithm in Wireless Sensor Network

0

In a Wireless Sensor Network (WSN), nodes are battery powered and then they are energy constrained. Network lifetime is the most important characteristics of performance for these networks. In this paper, we propose routing protocols that take into account the battery residual energy in sensor nodes and the energy required for transmission along the path toward the sink, which allows the distribution of energy load among the whole network nodes. Simulation results show that the network lifetimes increases up to 50% for the first node die and up to 114% for the last node die over comparable schemes like MLER protocol.
