摘要
本文提出了一种基于无线能量传输的能量均衡路由算法(WPTRA).该算法结合传统的分簇路由协议,采用基于剩余能量级别的簇头选取策略进行分簇.在数据传输阶段,当网络中某一节点能量低于预设的临界能量值TE_MIN时,通过计算无线能量传输效率和传输距离之间的关系,选择其附近能量较高的节点,通过无线能量传输技术对其进行能量补充.
In this paper,the researchers present an energy-balanced routing algorithm based on wireless power transfer（WPTRA）.Combined with the traditional routing protocols,this algorithm uses the cluster head selection strategy based on residual energy level.In data transfer phase,when the energy of the nodes is below the pre-set value TE_MIN,the nodes will choose the higher energy node nearby,according to the relationship between energy transmission efficiency and distance.Then,the nodes can get refueled from higher energy nodes by wireless power transfer technology.
