中文摘要：
针对结构健康监测无线传感器网络应用中,网络生命期不足的问题,提出一种低占空比网络下能量高效动态路由协议EEDRP（Energy Efficient Dynamic Routing Protocol）,该协议利用邻居节点剩余能量和链路质量动态确定转发集,通过基于转发集活动时隙预测的数据包重传机制,解决了因链路不可靠导致数据传输失败问题。最后,通过仿真对协议进行了验证,结果表明：该协议在保证数据收集低延迟和可靠性前提下,有效延长了网络生命期,满足结构健康监测应用要求。
英文摘要：
With the shortage problem of network lifetime in wireless sensor network of structural health monitoring, this paper proposes a routing protocol EEDRP （ Energy Efficient Dynamic Routing Protocol） in the low duty cycle network. The protocol dynamically works out a set of forwarding nodes by using neighbor nodes＇ link quality and re- sidual energy. At the same time, the protocol also solves the problem of data transmission failure caused by unrelia- ble links by the data packet retransmission mechanism which is based on predicting active time slots of forwarding set. At last, a simulation platform was established to verify the protocol, the result showed that the protocol can pro- long the network lifetime efficiently in the conditions of assuring reliability and low latency of data collection. There- fore it can meet the application requirements of structural health monitoring.
