摘　　要：无线传感器网络以其便捷性在电力运维等众多领域被广泛应用,但其续航能力受限于传感器的体积较为有限,无线能量传输技术以高度的灵活性成为打破能源瓶颈的主流方案之一。基于无线能量传输技术,数据采集策略更是可以进一步优化。相较于聚类、多跳等传统的路由方案,文章提出了一种分布式多跳数据采集算法,该算法赋予移动载具无线充电及数据采集功能,使其为网络补充能量的同时,节点可通过分布式多跳路由上传数据。仿真结果表明,该算法可有效均衡节点能量,延长网络生命周期。Wireless sensor networks are widely used in many fields such as power operation and maintenance due to their conveniences,but its endurance is limited by the size of the sensor.Wireless energy transmission technology will be one of the mainstream solutions to break energy bottlenecks with its high flexibility.Based on this technology,the data collecting strategy can be further optimized.Different from traditional routing schemes such as clustering and multi-hop methods,a distributed multi-hop data collecting algorithm is proposed in this paper.The algorithm allows mobile vehicles with wireless charging and data collecting functions to enable nodes to upload data through distributed multi-hop routing while the wireless charging equipment replenishes energy to the network.Simulation results show that the algorithm can balance energy and prolong the network lifetime effectively.
