PROJECT TITLE:

Security-Aware Relaying Scheme for Cooperative Networks With Untrusted Relay Nodes - 2015

ABSTRACT:

This paper studies the problem of secure transmission in twin-hop cooperative networks with untrusted relays, where every relay acts as both a possible helper and an eavesdropper. A security-aware relaying theme is proposed, which employs the alternate jamming and secrecy-enhanced relay selection to prevent the confidential message from being eavesdropped by the untrusted relays. To evaluate the performance of the proposed strategies, we tend to derive the lower certain of the achievable ergodic secrecy rate (ESR), and conduct the asymptotic analysis to examine how the ESR scales as the quantity of relays increases.
