摘要
本文围绕无线传感器网络在道路交通中的应用展开讨论,根据带状拓扑结构的特殊性,提出了一个分两级网络的路由协议,由上级节点发送路由请求建立路由,下级节点维护本地路由,并将下级网络按地理位置分成无簇头的分簇结构。应用实践表明,带状拓扑结构下,此路由协议简单,容易实现,开销小等。
The application of wireless sensor network in traffic is discussed. Based the particularity of banded topology, the network is divided into two hierarchies, and the higher hierarchical nodes send request to find the routing, but the lower hierarchical nodes maintain the route table. The lower hierarchical network is separated into multiple clusters without the cluster head based the node＇s location. The application results indicate this routing protocol for banded topology is simple, implemented easily and low expense.
