针对LEACH协议中簇头选择的不合理以及多个簇头与基站远距离通信能量消耗过多的问题,提出一种新的能耗均衡的多跳路由算法.在簇头数最优的前提下,充分考虑节点的能量和位置因素,结合PEGASIS协议中节点成链思想构造簇头间的多跳路由,最后由链上担任Leader的节点完成与基站的数据通信.NS2仿真实验表明,与LEACH和LEACH-C相比,该算法能更好的优化簇的结构,均衡网络能耗,延长网络生命周期.
Aiming at the unreasonable choice of cluster heads in LEACH protocol and the energy consumption of long distance communication between cluster heads and base stations, a new multi-hop routing algorithm with balanced energy consumption is proposed. Under the premise of the optimal number of cluster heads, , Taking fully into account the node energy and location factors, combined with PEGASIS protocol node into chain thought of multi-hop routing between cluster heads, and finally by the chain as a leader of the node to complete the data communication with the base station.NS2 simulation experiments show that LEACH and Compared with LEACH-C, this algorithm can better optimize the structure of the cluster, balance the network energy consumption and extend the network life cycle.
