摘要
为解决无线传感网络在开发部署方面存在的调试困难问题,提出了支持协议扩展的无线传感网络协议分析器的设计方案。实现了基于TinyOS的Telosb节点对IEEE802.15.4协议数据帧的抓取;采用XML文件描述和解析协议数据包结构,适用于各种不同的传感网络平台和协议栈;介绍了协议文件的预处理细节,数据的多角度可视化分析,基于决策树模型的故障诊断,以及通过分层架构实现大规模的网络监测。实验证明,该系统具有较高的可扩展性和灵活性,具有一定的应用价值。
To address the debug issues in developing and deploying of wireless sensor network, a scalable wireless sensor network protocol analyzer is designed. The analyzer realizes IEEE802.15.4 packet capturing by Telosb nodes running TinyOS, employes XML to define and parse protocols in order to support protocol extension. The detail of protocol definition preprocess and failure diagnosis based on decision tree are presented. The hierarchical model is used to form a large monitor network. The test results show that it is an effective tool to develop and deploy senor network.
