摘 要: | 路由协议是WSN研究中富有挑战性的问题。由于WSN自身的特点和通信需要,现有的无线自组网和互联网路由协议不适在WSN中运行,无线传感器网络路由协议以节约能源为首要目标,并采用折中机制,使用户可以在延长网络生存期和提高网络吞吐量、降低延迟时做出选择。无线传感器网络路由协议包括平面和分层路由协议两大类,文中介绍几种典型的分层路由协议,并根据路由性能指标进行了分析和比较,并指出了下一步的研究方向。

Abstract: | In search of WSN,routing protocol is a problem with challenges.The existing Ad-hoc and Internet protocol can't be directly applied to WSN because of its characters.One aim of WSN protocols is saving power and it takes advantage of compromise mechanism to prolong lifecycle,throughput and decrease delay.According to nodes based on each protocol's working principles,WSN routing protocols can be classified into flat and hierarchical.Analyzes and contrasts several basic hierarchical routing protocols. |
