摘要/Abstract

摘要： 将能量采集技术与大规模无线协作通信网络相结合，分析了在信息与能量同传环境下，大规模无线协作通信网络的中断性能.提出了一种中继协作传输协议，将位于源节点的中继区域内，并且能够成功解码源节点信号的中继节点定义为潜在中继，潜在中继用于协助从源节点到目的节点的信息传输；通过随机几何的数学工具，进一步分析了接收端使用选择合并接收方式下的中断性能，并对比了协作链路、中继链路以及直接链路三者的中断概率；最后对理论分析结果进行了仿真验证.验证的结果表明，最优中继策略下的中断性能最优.

关键词: 协作网络, 能量采集, 中断概率, 中继选择策略

Abstract: The outage probability in a large-scale cooperative relaying system based on simultaneous wireless information and power transfer (SWIPT) is investigated. A relay-assisted cooperative transmission protocol is proposed in which the relays that can decode the signal from the sources and are located in a relaying area become the potential relays, and are dedicated to assist the information transmission from the sources to the receivers. The outage probability is analyzed and the comparison is made among the direct link, the relay-only link, and the cooperative link. Simulation results are provided to validate our theoretical analysis.

Key words: cooperative network, energy harvesting, outage probability, relay selection strategies
