WSN路由协议'热点'问题的分析与研究

摘要

Through the analysis and comparison of two kinds of routing protocols in Wireless Sensor Networks: planar routing protocol and hierarchical routing protocol, a common problem in these routing protocols is proposed——hotspot issues.and how to improve the energy distribution of each node to achieve a balanced distribution.Firstly, several typical routing protocols are analyzed.Secondly, the hot issues of these typical protocols are analyzed and how to make the nodes cooperate efficiently so as to maximize the lifetime of the whole network.%通过对无线传感器网络中的两种路由协议——平面路由协议和分层路由协议的分析与比较,提出了这些路由协议中普遍存在的一个问题-热点问题,以及如何去改善,使各个节点的能量达到均衡分布.首先,分析了几种典型的路由协议;其次,对这些典型协议的热点问题进行分析与研究,如何使节点高效协作从而使全网的寿命达到最大化.
