| 摘 要： | 常规的无线传感器网络通过支持任意两点之间的通信,实现相距多跳的节点之间通信,然而在节点密集布设情况下,任意两点之间的通信会导致数据重叠,进而造成有限带宽资源的浪费.基于新型树状结构的无线传感器网络利用业务的方向性特点,在桥梁结构健康监测系统中,把节点构造成以传感器节点-汇集节点-基站节点的深度为二的树,数据按照业务方向进行传输,可以有效减少资源浪费,提高通信效率.文章对传感器节点在桥梁结构健康监测系统中的定位问题进行了研究并给出了解决方案,提出通过两种休眠调度方法来减少节点及网络的能量消耗;通过对汇集节点的数据聚合模型的研究,给出分布式数据处理能有效减少数据通信量的结论;通过对基站节点的网络协议转换的研究,来实现大规模无线传感器网络的组网与应用.最后对.NET构架和开发语言的特点进行了说明.

| Abstract: | Conventional wireless sensor networks realize multi-hop communication among nodes by supporting communication between any two points.However,when the nodes are densely deployed,communication between any two points will lead to data duplication,resulting in waste of resources of limited bandwidth.The wireless sensor networks which are based on a new tree structure use directional characteristics of the business.In the bridge structural health monitoring system,the network nodes are constructed into a sensor ... |
