摘要
针对在LEACH(low energy adaptive clustering hierarchy)协议中,所有节点均通过一跳通信将数据传输到簇头节点使簇头能耗太大而过快衰竭死亡的问题,提出了一种新的分簇的无线传感器网络多跳节能路由协议.簇头之间采用多跳方式将数据传送到基站,避免了单跳通信簇头节点能量消耗过大的问题.利用NS-2(networksimulator-version 2)的仿真结果表明该算法优于LEACH,能有效地降低节点的能耗,延长网络生命周期.
For the problem in the LEACH （low energy adaptive clustering hierarchy） protocol that the cluster heads die early caused by too much energy consumption of the cluster heads as the result of the one-hop transmission way from nodes to the heads, a new energy-saving multi-hop routing protocol based on clustering is proposed. Cluster heads transmit data to the base station in the multi-hop way to avoid the problem that cluster heads consume excessive energy by one hop. Simulation results based on NS-2 （network simulator-version 2） show that the algorithm does better than LEACH, and can lower the energy consumption of the node effectively and prolong the network＇s lifetime.
