摘要
针对LEACH协议中簇首分布不均匀和节点能量消耗不均衡的问题,为了提高节点能量利用率,延长网络运行周期,提高节点在网络运行过程中的存活率,提出了一种LEACH-NE改进算法。该算法综合考虑节点到基站的距离及节点的剩余能量等因素确定最佳簇首个数,然后通过考虑能量因素来优化簇首选择。仿真结果证明了改进后的路由协议在网络运行周期和网络能量消耗方面优于LEACH协议。
In view of the uneven distribution of cluster head nodes of LEACH agreement energy imbalance problems, in order to improve the utilization efficiency of node energy, prolong the network operation cycle, improve the survival rate in the process of nodes in the network operation, puts forward a improved algorithm LEACH- NE. The distance of the node to the base station considered in the algorithm and the residual energy of nodes factors determine the optimal number of cluster head, then by considering the energy factor to optimize selection of cluster head. The simulation results proved that the improved routing protocol in network operation cycle is better than that of LEACH agreement and the network energy consumption.
