一种贪婪地理路由协议的改进算法
An improved algorithm of greedy geographic routing protocol
摘要
Abstract
The greedy forwarding strategy is widely used in geographic routing protocol of wireless sensor networks (WSNs). Since the protocol has the problem of low routing efficiency in cases of routing void and serious packet loss,an im⁃proved algorithm of greedy perimeter stateless routing (GPSR⁃I) is proposed. The distance and direction from the target node and node density information are used to calculate the measurements when the GPSR⁃I algorithm is used to select the next⁃hop forwarding node,and then the next⁃hop forwarding node is determined. The simulation results show that,in comparison with the GPSR algorithm,the GPSR⁃I algorithm can effectively reduce the average end⁃to⁃end transmission delay and routing overhead, and improve the packet transmission rate.关键词
