摘要
随着定位技术的发展,基于地理位置的路由协议受到广泛的关注与研究。分析了无线传感器网络中地理位置路由协议GPSR的特性,详细阐述了GPSR协议中的贪婪转发及信标发送机制,遇到路由空洞时的局部优化问题,边界转发中所使用的右手法则和平面拓扑图的构造以及边界转发的实现等问题。
With the development of positioning technologies,the protocols based on geographical routing have received extensive attention and research.This paper analyzed the features of geographical routing protocol GPSR in the wireless sensor network,described greedy forwarding and beacon sending mechanism in the GPSR protocol,and described the Local optimum when encounter routing void,right hand rule and the structure of topology graph in the perimeter forwarding,and the realization of perimeter forwarding.
