Security Versus Reliability Analysis of Opportunistic Relaying
TLDR
We characterize the security-reliability tradeoffs (SRT) of conventional direct transmission from the source to the destination in the presence of an eavesdropper, where the security and reliability are quantified in terms of the intercept probability (IP) and the OP experienced at the destination, respectively.
