摘要 基于HEED算法中簇首与基站通信能量消耗过大的问题,提出了一种新的成簇路由算法.在参考HEED路由算法的基础上,整合多层分簇的思想,通过在网络拓扑的底层构建多个簇头节点的簇集合、在拓扑的顶层构建多跳转发机制,提出基于HEED的多层分簇路由算法.实验表明,该算法在簇头节点分布和网络生存时间方面较已有的算法有较大的提高. A lot of energy was lost when the cluster heads communicate with base station in HEED algorithm,new clustering algorithm was proposed.It integrates hierarchical clustering based on classical routing algorithm HEED,by adopting the multi-cluster head of the bottom level and the multi-hop forwarding mechanism of the top level,a hierarchical clustering routing algorithm Based on HEED was proposed.Simulation results show that the algorithm may efficiently improves the distribution of cluster head node and network lifetime compared to other algorithms.
