摘　　要：建立面向无线传感器网络,应用的实验系统,对于WSN算法的研究与应用具有重要的意义。设计并建立一套用于WSN定位算法测试与分析的无线传感器网络定位实验系统,系统由硬件平台和软件平台组成,硬件平台由Macaz节点、MIB600构成,自主开发的软件平台SNICI对数据进行处理并实时显示整个WSN的运行状态,具有一定的通用性和可扩展性。在实验系统平台上设计并完成了基于接收信号强度(Received Signal Strength Indicator,RSSI)的定位、跟踪的相关实验与研究,并测试和分析了系统性能。实验结果表明了该实验系统的可行性。实验系统的构建有利于对WSN定位算法进行测试、分析以及优化。It is very meaningful to establish a WSN - oriented testing system. The effort is to develop a Localization platform, which contains the software platform and the hardware platform. The hardware platform is composed of Macaz nodes and MIB600. The software platform SNICI （Sensor Networks, Institute of Control ＆ Information）can display the state of WSN in a real time manner, and can be easily deployed by applications for large scale sensor networks. On the platform, some research of localization and tracking can be validated. Results demonstrate that the platform is efficient. The localization approaches can be easily applied to the platform.
