WMSN中一种有效的地理路由空洞迂回算法
Efficient bypassing hole scheme for geographic routing in Wireless Multimedia Sensor Networks
摘要
Abstract
Routing holes problem is always hot in the research of Wireless Multimedia Sensor Networks. An efficient bypassing hole scheme BHRGR, which is aimed at the characteristic of geographic routing is presented. This scheme ascertains the position of holes by sending an observer packet in advance to get the information of nodes on the boundary of holes. It constructs a virtual rectangle which covers the hole to engender dynamic intermediate destination nodes. An efficient bypassing hole route is formed. Simulation results show that average hop counts of routing and energy consumption of this routing protocol decrease markedly. And it is safe to say that the proposed protocol decreases hole diffusion problem and improves network lifetime.关键词
