中文摘要：

由于传感器节点具有传感与通信两个功能,基于传感器网络的定位参考点选择不能仅仅考虑定位性能或网络通信性能,根据不同的传感半径与通信半径选择不同的设置方案成为一个亟待解决的问题。为此,对比分析了三种常见的规则网络拓扑结构的性能,提出了一种参考点设置方法。实验结果表明只有依据通信半径与传感半径的关系设置参考点才能够达到较优的覆盖效果。

英文摘要：

As the sensor nodes have two functions： sensing and communication,reference point selection based on wireless sensor networks doesn＇t only consider the localization performance or the network communication performance.Therefore,selecting node setting method according to different communication radius and sensing radius becomes a considering question.This paper comprised and analysised the performance of three common regular topology and proposed a novel method for reference points setting.The experiment result shows that only by setting reference points according to the relationship between communication radius and the sensing radius,can optimize the coverage performance.
