摘要

研究了由源节点、目的节点和多个中继节点组成的认知解码转发（DF）中继网络中物理层安全与可靠性折中方案。该方案以保障最大安全主链路信道容量为目标，提出了存在窃听攻击情况下的最佳中继选择方案。以传统直接传输方案作为基准，给出了安全性与可靠性折中性能（SRT）。数值仿真结果表明，所提方案的SRT性能优于传统直接传输方案的SRT，并且其性能随着中继数量和在一定中继数下Nakagami信道衰落因子m的增加而显著改善。

Abstract

Physical layer security (PLS) and reliability tradeoff scheme in a cognitive decode-and-forward (DF) relay network consisting of one source

one destination and multiple relays was investigated.A best relay selection scheme (BRS) against eavesdropping attack was proposed

in order to guarantee the maximum secure main link channel capacity.Traditional direct transmission scheme was taken into consideration as a benchmark.In addition

security-reliability tradeoff (SRT) performance was presented.Numerical results show that the proposed SRT scheme strictly outperforms traditional direct transmissions in terms of SRT performance.SRT performance can be enhanced obviously with the increasing of relays and Nakagami channel fading factor m for a given numbers of relays.
