In the wireless sensor networks S-MAC(Sensor MAC) protocol,there exists imbalance between the energy consumption of virtual cluster boundary and that of other non-boundary nodes.Firstly,an improved energy-efficient agreement called the EES-MAC(energy-efficient sensor MAC) is proposed,which uses the newly two added coordination variables to unify the work cycle of all nodes,and boundary nodes only can work in a synchronized cycle,thus the influence of the boundary nodes have on the network is eliminated.Secondly,analysis this new protocol theoretically and simulate.The simulation results proves that the improved protocol basically eliminate the impact of the virtual cluster boundary node compared with the traditional protocol,and achieve a efficient network result,so the network lifetime is improved.
