摘要

针对无线携能（SWIPT）中在节点能量受限情况下的缓存队列机制半双工（HD）中继选择的问题，研究了SWIPT中能效优先的缓存队列机制中继节点选择方案和所提策略的系统能效。给出了基于能效优先的缓存队列机制SWIPT最佳接收/转发中继节点选择方案。数值仿真结果表明，所提策略可以有效降低SWIPT网络的中断概率，实现缓存队列SWIPT中能效与中断性能的折中。

Abstract

Aiming at the problem of buffer-aided half-duplex (HD) relay selection in simultaneous wireless information and power transfer(SWIPT) with energy constraint

energy-efficiency priority based buffer-aided relay selection scheme in SWIPT was investigated.Moreover

SWIPT system energy efficiency was studied

and an appropriate mathematical model was constructed to perform energy efficiency based buffer-aided optimal receive/transmit relay selection in SWIPT.Numerical results show that the proposed scheme effectively reduces SWIPT outage probability and achieves the tradeoff between energy efficiency and outage performance in buffer-aided SWIPT.
