无线传感网络中基于无线能量补给的能量感知路由算法

针对无线传感网络中随机分布传感器节点能量消耗不均衡的问题,提出了一种基于无线能量补给的能量感知路由算法。休眠节点不仅可以在无线携能通信(Simultaneous Wireless Information and Power Transfer,SWIPT)传输方式下通过功率分割方法进行无线能量补给,还可以在信息传输方式下通过无线能量收集方法进行能量补给,重新进入活跃状态,为信息传播提供更好的路由,提高传感器节点的能量利用,延长传感网络的使用寿命。在该算法中,通过优化节点间的信息和能量分配,最小化传输功率,引入能量路由度量方法,选择能耗最小的路径作为传输路径。仿真结果表明,本文提出的算法可以有效地利用节点资源,均衡多跳能量受限无线传感器网络中的能量分布。

Energy Sensing Routing Algorithm Based on Wireless Power Supply in Wireless Sensor Networks

Aiming at the problem of unbalance energy consumption of randomly distributed sensor nodes in wireless sensor networks,an energy aware routing algorithm based on wireless power supply is proposed.Sleep nodes is able to be reactive by not only harvesting energy through power splitting method with simultaneous wireless information and power transfer(SWIPT)mode,but also through wireless power transfer with information transmission mode,which can provide a better route for information transmission.Thus,leading to improve the energy utilization of the sensor nodes,and prolonging the service life of the sensor network.In the proposed algorithm,the transmission power is minimized by optimizing the allocation of information and energy among the wireless nodes.Moreover,the transmission path with the lowest energy consumption is selected by introducing an energy routing metric.Simulation results show that the proposed algorithm can effectively utilize node resources and balance the energy distribution in multi-hop energy-constrained wireless sensor networks.
