摘　　要：为了延长多跳网络的网络寿命,将无线能量传输(wireless energy transfer,WET)技术应用于多跳网络,并提出基于蜂拥算法的最优WET时间的延长网络寿命算法(FENL)。FENL算法先建立基于WET的多跳传输系统模型,并构建最大化网络寿命的目标优化函数。然后,利用蜂拥算法求解目标函数,进而获取每个节点的最优WET时间,进而最大化网络寿命。仿真结果表明,相比于传统的未采用无线能量采集和WET技术,FENL算法有效地延长了网络寿命,且FENL算法的网络寿命逼近于穷搜索法的网络寿命。To extend the lifetime of a multihop network, wireless energy transfer(WET) technology is used to multi-hop network, and flocking algorithm-based extending network lifetime algorithm(FENL) is proposed in this paper. In FENL algorithm, WET-enabled multi-hop transmission model is established.Then optimization function of maximizing network lifetime is constructed. In addition, the flocking algorithm is used to solve the optimization function, and the optimal WET time of each node are obtained to maximize the lifetime of multihop networks. Simulation results show that network lifetime of the proposed FENL algorithm outperforms the the conventional algorithm without Wireless Energy Harvesting and WET. Moreover, network lifetime of the FENL algorithm is close to network lifetime of optimization function by exhaustive search method.
