| 摘 要： | 减少能量消耗,延长网络生存时间,是无线传感器网络中路由协议要考虑的重要问题;在对LEACH协议和定向扩散协议进行分析的基础上,针对这两种协议中存在的问题,提出一种基于簇首定向扩散(CHDD)的路由协议;该协议改进了簇首选择算法,在簇首与sink节点之间采用定向扩散算法,该协议可以有效地延长整个网络的生存时间,仿真结果证明该协议的性能改进。

| Abstract: | Reduced energy consumption and prolonged lifetime of a network are important issue to be considered for routing protocol of wireless sensor networks.Based on the analysis of the protocol LEACH and directed diffusion protocol,aimed to the problem of two protocols,this paper presents a cluster head directed diffusion(CHDD) routing protocol.The protocol improves the selection algorithm of cluster head and use directed diffusion algorithm between cluster head and sink node.The protocol can effectively prolong t... |
