基于分簇的无线传感器网络MAC节能算法
MAC Energy-efficient Algorithm in Wireless Sensor Network Based on Clustering
摘要
Abstract
In order to reduce node energy consumption and improve channel utilization, an energy-efficient Medium Access Control(MAC) algorithm based on cluster for Wireless Sensor Network(WSN) called EEC-MAC is proposed. It adopts time-slot factor based on TDMA to adjust slot size to reduce data transmission delay and allows a longer sleep time for the part of nodes which have no data transmission to save energy, and forms a slot order by the residual energy coefficient to reduce the state conversion energy consumption. It uses CSMA/CA mechanism to communicate with cluster heads. Simulation results show that EEC-MAC has a better energy saving, a smaller average network delay and a longer lifetime.关键词
