基于多窃听协作的最佳中继安全可靠性能研究
Security versus reliability analysis for multi-eavesdropper cooperation wireless networks with best relay
摘要
Abstract
Physical-layer security could be used to effectively combat eavesdroppers and the transmission reliability of the main link could be improved. A wireless relay network with multiple both decode and forward eavesdroppers and re-lays were considered, in the presence of the link from source to destination. A best relay selection scheme based on multi-eavesdropper's cooperation was proposed, and the outage probability and the intercept probability was deduced under both schemes without relay and with best relay. Then, the security and reliability influenced by different relay selection schemes were analyzed. The simulation results show that the achievable channel capacity at the destination node and the system outage probability are directly affected by different relay selection scheme. Lower system outage probability can be achieved by the proposed scheme, and the system outage probability and intercept probability are both decreased with the increase of the number of relays. The intercept probability increases with the increase of the number of eavesdroppers, which, however, can be reduced by increasing the number of relays to ensure the main link's reliable transmission.关键词
