基于能量均衡的LEACH协议的研究

Research on LEACH Protocol Based on Energy Balance

无线传感器网络节点能量有限,因此为了避免由于节点的能量不足而造成网络瘫痪,在组网过程中必须要充分考虑到节点能量的情况,Leach协议是其中一种典型的网络分簇路由协议。针对传统leach协议在分簇过程中未能考虑网络内节点能量以及簇首数量的基础上,提出一种新的簇首选取优化算法,旨在达到均衡网络能量、延长网络生命周期的结果。经OPNET仿真表明,该算法能快速选择簇首、节省节点能量以及均衡网络的能量分布,最后有效地延长网络的生命周期。

The energy of wireless sensor network nodes is limited,so in order to avoid network paralysis caused by insufficient node energy network,the node energy must be fully considered in the process of networking.Leach protocol is one of the typical network clustering routing protocols.On the basis of failing to consider the energy of nodes in the network with traditional LEACH protocol and the number of cluster head in the clustering process,a new cluster head selection algorithm is put forward,in order to balance the network energy,and to prolong the network life cycle.The OPNET simulation shows that this algorithm can quickly select cluster head,save energy of nodes and balance network energy distribution,and finally prolong the lifecycle of the network effectively.
