| 摘 要： | 无线传感器网络（WSN）有着广阔的应用前景,作为传感器网络关键技术的路由协议也成为研究的热点之一,利用地理位置信息设计的路由协议逐渐成为主流。本文针对无线传感器网络的路由协议GEAR存在的＂无效节点区域＂问题,分析了GEAR协议及造成无效节点的原因,并提出了一种改进方案。通过Hello消息交换机制实现节点间邻居信息的交换,并通过中间节点的转发实现对无效节点区域问题的规避。

| Abstract: | Wireless Sensor Network（WSN） has broad application prospects,as the key technologies of routing protocol has become one of the hot research,geographical location information design of routing protocol gradually become the mainstream.Based on wireless sensor network routing protocols of existing GEAR ＂invalid node,analyzes the regional problems caused by void node GEAR agreement and the reasons,and puts forward an improved scheme.Through Hello message switching mechanism between the nodes of information exchange,and neighbors through intermediate nodes forward to avoid invalid node of regional problems. |
