摘要 将低功耗自适应集簇分层(Low energy adaptive clustering hierarchy,LEACH)协议运用到传感器节点位置随机动态变化的无线传感器网络中,分析了该协议的优缺点,并提出了改进后的A_LEACH协议。该协议将节点与基站距离、节点剩余能量作为考虑因素来建立路由协议,动态地确定簇首节点的数目和分布。仿真试验表明:A_LEACH协议降低了节点的死亡率,增加了采集信息的可靠性,能有效延长网络的寿命。 将低功耗自适应集簇分层(Low energy adaptive clustering hierarchy,LEACH)协议运用到传感器节点位置随机动态变化的无线传感器网络中,分析了该协议的优缺点,并提出了改进后的A_LEACH协议。该协议将节点与基站距离、节点剩余能量作为考虑因素来建立路由协议,动态地确定簇首节点的数目和分布。仿真试验表明:A_LEACH协议降低了节点的死亡率,增加了采集信息的可靠性,能有效延长网络的寿命。
