摘要:

在具有射频能量捕获功能的无线传感器网络中,为有效传输数据并延长网络寿命,需要合理部署供能节点和捕能节点。为此,基于无线传感器网络技术,提出一种智能电网中具有能量捕获功能的数据传输方案,并设计一种具备优先充电机制的数据汇聚树路由算法。在捕能节点 周围设置至少一个供能节点,利用整型线性编码和最小权重捕获支撑树路由算法实现节能的数据传输,在最终构建的树中选择负载重的捕能节点,在网络运行中对其进行优先充电。仿真结果表明,该方案具有较小的算法复杂度,能在完成数据传输的同时有效延长网络寿命。

Abstract:

In Wireless Sensor Network(WSN) with Radio Frequency(RF) energy scavanging,Energy Providing Node(EPN) and Energy Harvesting Node(EHN) are needed to deploy reasonably to transmit data and prolong network lifetime.A data transmission scheme based on WSN technology with RF energy scavanging in smart grid is presented,as well as a data aggregation tree routing algorithm with prior-recharging mechanism.At least one EPN is arranged around the EHN.Energy-efficient data transmission can be achieved through Integer Linear Programming(ILP) and least-weight-scavanging spanning tree algorithm.Some heavy load EHNs are choosed for prior recharging in network operation in the finally built tree.Simulation results show that the scheme has smaller algorithm complexity,and can extend the network lifetime effectively while completing data transmission.

Key words: smart grid, energy scavanging, aggregated routing, Wireless Sensor Network(WSN), prior recharging
