Secrecy outage probability analysis for cooperative communication with relay selection under non-identical distribution
Esa R. Alotaibi, Khairi Ashour Hamdi · 2016
In this paper, secrecy outage probability is analyzed in a cooperative network for an independent but non-identically distributed (i.n.i.d) Rayleigh fading channel. By using multi-trusted decode and forward relays, the model assumes direct links between a sender (Alice) and receiver nodes (Bob and an eavesdropper). The protocol employed herein selects the best relay with the highest signal-to-noise ratio (SNR) in relation to the destination (Bob). The eavesdropper's channel state information (CSI) is neither available to the sender nor to the best relay, while maximum ratio combining (MRC) is employed at Bob and the eavesdropper. Finally, the theoretical analysis is validated through simulation, and the results show that performance is enhanced with an increasing number of relays in the event of a direct link between the sender and the receiver's terminals.
