针对输电线路无线传感网业务的周期性特点和传感器野外长时间工作要求,综合考虑了节点间能量标准化后的统计参数、路径上的能耗与节点的总能量、路由跳数,提出了基于休眠唤醒机制的传感网络低功耗通信技术,之后提出算心跳信息预测和功耗智能分配方法,来寻求路径上节点个数的最小化,满足电力输电线路状态监测感器网络对时延的需求,一方面考虑网络路由的低功耗,需要寻找整体功耗最小的路径,减少网络消耗的总能量;另一方面考虑节点能源消耗因素,使能量较高的节点能够更频繁的参与网络数据的转发,能量较低的节点尽量少的参与网络路由,延长网络寿命。
Considering the periodic characteristics of wireless sensor network (WSN) service in transmission lines and the long-time working requirements of the sensor in the field, considering the statistical parameters of energy standardized between nodes, the energy consumption of nodes and the total energy of nodes and routing hops, Sleep wake-up mechanism of the sensor network low-power communication technology, and then proposed to calculate the heartbeat information prediction and intelligent power distribution method to find the minimum number of nodes on the path to meet the power transmission line condition sensor network to delay Demand, on the one hand to consider the low power consumption of network routing, the need to find the path of the smallest overall power consumption and reduce the total energy consumption of the network; on the other hand consider the node energy consumption factors, so that energy nodes can more frequently participate in network data Of the forwarding, lower energy nodes to participate in network routing as little as possible to extend network life.
