摘要 能量受限是无线传感器网络应用的瓶颈问题,为了使无线传感器网络获得稳定持续的能量来源,提出将无线携能通信(SWIPT)技术应用到无线传感器网络中。基于时分多址(TDMA)的通信方式建立了适应于无线传感器网络的无线携能通信系统新优化模型。通过凸优化问题的求解得到该优化模型的最优分配策略。利用仿真实验对无线携能通信在无线传感器网络中应用的可行性进行了分析,对方法的有效性进行了验证。 Energy constraint is the bottleneck for the application of wireless sensor networks( WSNs),in order to provide the WSNs with stable and sustainable energy,simultaneous wireless information and energy transfer ( SWIPT)is proposed. Construct new optimizing model adapted to WSNs based on time division multiple address ( TDMA). On this basis,the optimum allocation strategy can be obtained through solution of convex optimization problem. Simulation results prove the feasibility of application of SWIPT in WSNs and effectiveness of the proposed method.
