无线传感器网络研究的一个重点就是如何利用有限的能量来使得该网络能够在更长的时间内有效的工作。所以网络的节能成为最近研究的一个重点,而网络拓扑控制也是研究节能的一个方面,阐述了一种基于蜂窝式结构[1]的拓扑控制算法。在这种蜂窝式结构的基础上,在路由转发的时候加上地理路由协议(GPSR)中的两个算法[2-3]:贪心传递(Greedy Forwarding)算法和周界传递(Perimeter Forwarding)算法[4],以此来绕过一个路由空洞或者障碍物,从而达到节省网络能量,延长网络运行时间的目的。
One of the focuses of wireless sensor network research is how to utilize the limited energy to make the network work effectively for a longer period of time. Therefore, energy-saving network has become a focus of recent research, and network topology control is also an aspect of energy-saving, and expounds a topology control algorithm based on cellular structure [1]. Based on this cellular structure, two algorithms in the Geographic Routing Protocol (GPSR) are added during route forwarding [2-3]: Greedy Forwarding algorithm and Perimeter Forwarding algorithm [4], in order to bypass a routing hole or obstacle, so as to achieve the purpose of saving network energy and prolonging network running time.
