摘要: 现有能量捕获无线传感器网络路由方案较少考虑链路质量以及节点能量是否足够等问题。为此,对能量溢出感知的剩余能量最大化路由问题进行建模,结合储能设备上能量溢出浪费情况和基于链路数据包传递率的通信能耗指标,提出一种能量溢出感知的路由方案,选择通信能耗和溢出能量总和较低的路由。实验结果表明,与Martinez G等人提出的路由方案(IEEE Sensors Journal,2014,No.9)相比,改进方案可使节点剩余能量提高50%左右。

Abstract: The existing Energy-harvesting Wireless Sensor Network(EH-WSN) routing schemes almost do not consider some important issues like the link quality,whether the node energy is enough,etc..So,the energy wastage-aware residual-energy-maximized routing problem for EH-WSN is formulated.Taking into account the energy overcharge wastage and link packet delivery rate based communication energy consumption,an improved wastage-aware routing scheme is proposed,which finds the route with low communication energy consumption and energy overcharge wastage.Simulation results demonstrate that,compared with the wastage-aware routing scheme proposed by Martinez G,et al(IEEE Sensors Journal,2014,No.9),the proposed routing scheme is able to improve the node residual energy by about 50%.

Key words: Wireless Sensor Network(WSN), Energy-harvesting Wireless Sensor Network(EH-WSN), routing scheme, energy saving, optimization theory
