Secure Selection for Decode-and-Forward Cooperative Networks with Untrusted Relay
摘要
Abstract
Secure communication in decode-and-forward cooperative networks with untrusted relay in the presence of direct links is investigated in this paper.In the considered system,one base-station is selected for secure transmission to the destination node with the aid of an untrusted relay node.Three selection criteria are proposed to improve the secrecy capacity based on both the direct links and the relaying links.The exact close-form expressions and corresponding asymptotic expressions on secrecy outage probability are derived.From the asymptotic expressions and simulation results,the sub-optimal criterion has the same performance with the optimal criterion.Furthermore,the partial selection criterion achieves the full diversity gain.关键词
