| 摘 要： | 在分簇协议LEACH和链状协议PEGASIS的基础上,提出一种新的基于数据融合的分簇路由算法.簇首节点采用多跳方式传输数据,并根据周围节点的密集程度构造不同大小的簇;簇内节点计算上行和下行节点构造数据融合树,采用时分复用调度算法进行多跳路由.NS2仿真结果表明该路由算法均衡了各个节点的能量消耗,延长了网络存活时间,并降低了网络延迟.

| Abstract: | Based on clustering protocol LEACH and chaining protocol PEGASIS,this paper presents a novel clustering algorithm for data aggregation.Cluster heads adopt multi-hop communication to send data and form different size of cluster by density of the nodes around them.Computation of upward nodes and downward nodes in every cluster to form data aggregation tree,nodes in one cluster adopt multi-hop communication by time division multiple access schedule.The simulation shows that this algorithm balances energy consu... |
