用于智能电网的有差别射频充电传感器网络

针对应用于智能电网中的无线传感器网络(WSNs)节点能量受限问题,分析了基于无线射频充电技术的为传感器节点充电技术,改进了可持续无线充电传感器网络(SWRSNs),提出有差别射频充电传感器网络(DRRSNs)技术,增加节点的优先级设置,建立整数线性规划模型,用CPLEX求解模型确定标志性节点位置。求解数据表明:节点获得的能量平均提高105%,高优先级节点比低优先级节点平均多获得43%的能量,提高了节点的寿命,保证了WSNs的可靠性,但是路径访问效率平均降低了14%。

Differentiated RF rechargeable sensor networks for smart grid

Aiming at problem of limited energy of nodes in wireless sensor networks （WSNs） applied in smart grid,in order to increase sustainability of WSNs, focused on analysis of sustainable wireless rechargeable sensor networks（SWRSNs） based on the RF wireless charging technology and put forward differentiated RF rechargeable sensor networks（DRRSNs） which increase the node priority setting, an integer linear programming model is built to determine the location of landmarks. The solved data of integer linear programming model through CPLEX show that obtained energy of node of DRRSNs can be improved by an average of 105 % and the high priority sensor node could receive average 43 % more energy than low priority sensor node. So DRRSNs can effectively improve the lifetime of the nodes and ensure the reliability of WSNs, but the path traversal efficiency is reduced by an average of 14 %.
