| 摘 要： | 针对目前无线传感器网络实验床普遍缺乏性能测量机制的问题,基于TinyOS的特点,提出了一种支持对实验对象进行现场测量的实验床体系结构.将轻量级测量实体嵌入到实验床中,对被测系统、测量指标进行约束与定义,设计了高能效的测量方法和测量算法,实现了对实验中节点能耗、链路质量、吞吐量、丢包率、时延、网络拓扑等性能参数的高效可靠获取,解决了传感器网络协议或应用的实时测试问题.该实验床技术支持分布式多点测量和平面、分簇、Multi-Sink等多种网络结构,提高了实验床设施的利用率和实验效率.实验案例证明了其良好的易用性、普适性和可扩展性.

| Abstract: | To solve the problems in real-time evaluation and deep analysis of wireless sensor network (WSN) applications, a novel Mote and TinyOS based WSN testbed architecture characterized by supporting distributed in-situ performance measurement of experimental objects was proposed. The system under test and the measurement metrics were defined and a set of high energy-efficient measurement algorithms were implemented. The lightweight measurement entity built in the testbed during experiments enables the reliably a... |
