桥载设备工况监控网络中能耗均衡的路由协议

摘要

针对桥载设备工况监控网络中传感器节点通信时易发生数据拥塞,造成能耗高而过早死亡等问题,提出一种基于分簇的数据融合算法.通过评估网络平均能量、能量消耗速度以及一级、二级节点位置参数选出簇头,保证簇内网络的能耗均衡;权衡节点路径和距离确定根节点,建立数据融合树去除冗余数据,防止因为传输数据量大而占据网络带宽造成拥塞,以及节点进行大量数据通信耗费不必要的能量而减缩生命周期.仿真结果表明,该方法与原有LEACH算法相比能更好地利用有限带宽资源均衡节点的能量消耗,提高传输数据率,保证网络监控系统的持久性和可靠性.%A data fusion algorithm based on clustering was proposed for the WSN routing in the monitoring network of bridge load equipment aiming at the problem of data congestion, high energy consumption and premature death.The network average energy, energy consumption speed and location parameter of nodes were evaluated to select cluster head, to balance energy consumption of the cluster network.The node path and distance were evaluated to determine the root node, and the data fusion tree was established to remove the redundant data, to avoid large amount of data transmission and occupying the network bandwidth caused by congestion, as well as unnecessary energy of large data communication and reduced life cycle.Through simulation, the proposed method can improve the energy consumption and the transmission data rate, while ensure the reliability of the network monitoring system.
