无线传感器网络的地理路由算法综述

Survey on Geographic Routing in Wireless Sensor Networks

在无线传感器网络体系结构中,网络层的路由技术至关重要。地理路由算法由于其扩展性方面的优势逐渐成为无线传感器网络中的一个研究热点,近年来提出了很多地理路由算法。根据对现有算法的分析,把地理路由算法分为三类:基于平面化的地理路由算法、基于特征节点的地理路由算法和基于拓扑特性的地理路由算法。同时,针对具体的算法进行了探讨,分析了各个算法的优劣和性能、特点等。最后总结了该领域当前研究现状,并指出未来的研究策略与发展趋势。

In the architecture of Wireless Sensor Networks（WSN）, routing technology is a very important issue. Geographic Routing is becoming a hot issue in WSN because of its scalability, and there are many algorithms proposed in recent years. We classified the geographic routing algorithm into three classes according existing algorithms： planaring based algorithm,characteristic nodes based algorithm and topology based algorithms. We discussed concrete algorithms and analyzed the performance, characters of them. Finally, we summarized the current research work and pointed out the future research direction.
