Title : Impact of Outdated Channel Estimation on Secure Opportunistic Relaying System 
Authors : Jonghyun Bang, Seokjung Kim, Taehyung Kim, and Daesik Hong 
Conference : ICEIC 2017 
Abstract : In this paper, we study an opportunistic relaying system with secrecy constraints, where a number of eavesdropper nodes may overhear the source message. To deal with this problem, we consider two relay selection strategies. The first scheme tries to reduce the overheard information at the eavesdroppers by choosing the relay having the lowest instantaneous signal-tonoise ratio (SNR) to them. The second strategy is a conventional relay selection that seeks the relay having the highest SNR to the destination. The system performance in terms of the achievable secrecy rate of the two schemes are analyzed and confirmed by Monte Carlo simulations.
