摘要
针对无线传感器网络在事件触发类监测中的应用,提出了在该类应用中的解决方案。分析归纳了无线传感器网络在事件触发类监测中的应用需求,提出了满足该需求的无线传感器网络布设方法及采取的路由协议与数据聚合算法。分析了两种布设方式的优缺点,确定了事件触发监测系统采用非冗余布设方式;路由协议采用改进的APTEEN算法,改进了阈值和休眠策略;数据聚合在簇头节点进行,将来自簇内节点的多个数据包在网络层聚合为一个数据包后传送给基站。实验结果表明了该解决方案的有效性。
To solve event-triggered monitoring applications based on wireless sensor networks,the corresponding solutions are proposed.The demands of event-triggered monitoring applications based on wireless sensor networks are analyzed and summarized,the suitable solutions which involve the deployment of wireless sensor networks,routing protocol and data aggregation algorithm are put forward.After analyzing the advantages and disadvantages of two deployment ways,the non-redundant deployment is adopted in event-triggered monitoring system.The improved APTEEN routing protocol which improved threshold and sleep strategies is adopted.Before sent to the base station,multiple data packets are aggregated to one packet on network layer by cluster head node.Finally,the feasibility of the solutions is validated by experiments.
