摘要
Abstract
Because the lifetime of Wireless Sensor Network(WSN) is restricted by the energy of nodes, this paper presents an energy saving algorithm based on Node Survival Time(NST). According to the surplus energy after the node's receiving, sending and processing data, the concept "wheel" of the energy saving algorithm is proposed. It improves on the basis of the existing threshold function and the cluster-head selection gets its best cluster head node by the improved threshold function so as to prolong the life time of the nodes and prolong the round cycle of the cluster nodes with lower energy consumption. Simulation results demonstrate that the algorithm is efficient for reducing dead speed of nodes and increasing the network lifetime.关键词
