| 摘 要： | 在LEACH协议的基础上进行改进提出了一种高能效无线传感器网络协议——LEACH-M。LEACH协议中,簇首节点与基站之间直接传送数据,离基站较远区域的簇首能耗较大,这影响了系统寿命。LEACH-M协议在簇首形成阶段采用CSMA/CA(carrier sense multi-access with collision avoidance)作为MAC协议,并在簇首节点与基站之间引入了改进的多跳路由算法,使网络中各簇的能耗更加均匀。仿真结果表明,与LEACH相比,LEACH-M协议具有更好的能量有效性,并且提高了无线传感器网络的寿命。

| Abstract: | This paper presented a novel energy-efficient protocol for WSN called LEACH-M,which combined improved multiple-hop routing form cluster head to BS instead of directly transmission in LEACH.Besides,LEACH-M adopted CSMA/CA as the MAC protocol.Simulation results,compared with LEACH,demonstrate that this novel protocol is more energy-efficient and prolongs the lifetime of the whole network. |
