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.
