摘要
物联网传感网络广泛应用在环境监测和模式识别等领域,物联网传感网络的路由协议通过多跳汇聚树路由网络进行组网,随着节点数目的增多容易出现链路故障,需要进行路由修复和改进设计。提出一种基于链信息头抽取和信息源定位的物联网传感器网络路由改进设计方法。构建了物联网下传感器网络的组网和路由探测模型,采用链路信息簇头节点抽取和信息源定位方法进行链路路由信息数据聚集,采用预加重方法广播竞选簇头节点的能量损失,通过双向链路估计得到路由节点的数据传输协议,采用链路节点能量和Sink节点距离分层方法实现路由优化设计。仿真结果表明,采用该方法进行物联网传感网络的路由优化设计,提高了链路信息收发和数据传输的可靠性和吞吐量,性能优越。
In the field of environmental monitoring and pattern recognition,the routing protocols of the Internet of things sensor network are more prone to link failures,which need to be repaired and modified.An improved design method of sensor network routing based on link information header extraction and information source location is proposed.The network and route detection model of sensor network is constructed,and the information is gathered by the link information cluster head node and the information source location method.The energy loss of the nodes is estimated by using the method of preweighting method.Simulation results show that the proposed method is used to optimize the routing of the network of things,which improves the reliability and throughput of the link information and data transmission.
