摘要：Network lifetime is perhaps the most important metric for the evaluation of sensor networks. In a resource-constrained environment, the consumption of every limited resource must be considered The network can only fulfill its purpose as long as it is considered alive, but not after that. It is therefore an indicator for the maximum utility a sensor network can provide. Energy efficiency is therefore of paramount importance in sensor networks that are constrained by limited resources. Designing an efficient routing protocol for a sensor network is challenging due to factors such as limited resources, concentration of load in a limited portion of the network, and routing of redundant information. In this paper we have analyze how the residual energy level of each cluster can be optimized to make a significant improvement in the functional lifetime of the wireless sensor network.
