在无线传感器网络中,定向扩散算法多源节点在数据传播、路径加强时存在链路冗余,会造成不必要的网络能量消耗.针对该问题,提出一种新的源节点成簇的路由算法.网络中所有源节点组成一个簇,根据节点向心度推选簇头,sink节点仅与簇头进行通信,避免网络中过多的链路冗余.理论分析和仿真实验表明,该算法的能量损耗低于定向扩散路由算法,改进效率与网络规模及网络运行时间相关.

To solve the problem on unnecessary energy-consumption caused by redundant links in Directed Diffusion(DD) algorithm during data propa-gation and reinforcement between multiple sources and sink node in Wireless Sensor Network(WSN), a new routing algorithm, Directed Diffusion based on Cluster of Sources(DD-CS) is presented. All the sources of network are in a same cluster, and redundant links are reduced when sink node only communicates with the cluster head chosen by centripetal degree of node. Theoretical analysis and simulation show that DD-CS is effective and energy consumption is lower than that of directed diffusion, the improved efficiency is related to the network scale and running time.
