无线传感器网络(WSN)具有与传统网络显著不同的特点,导致应用于传统网络的路由协议并不适用于无线传感器网络,因此有必要研究新的路由协议为之服务。文中在介绍WSN的特点后,将着重讨论其路由过程并把整个过程分为路由建立和路由更新两个阶段,通过对当前应用较多的路由协议分析,对每个阶段进行阐述;文章最后对WSN路由协议未来的研究策略与发展趋势提出了一些具体研究意见。
Wireless sensor networks are quite different from protocols could not serve WSN well. Therefore it is necessary traditional networks, and the traditional routing to develop new routing methods. In this paper, characteristics of WSN are described first, then the routing problems discussed, The whole routing process is separated in two phases: routing setup and routing update. Some existing WSN routing protocols are analyzed and each phase is explained. Finally, strategies for future research and trends of routing protocols are summarized.
