Relay Selection for Multi-Destination in Cooperative Networks with Secrecy Constraints

Abstract-Most of the prior researches in the field of relay selection techniques under security constraints for cooperative networks have only concentrated on single destination, although the factual communication environment comprehends multiple transmitters and receivers. This paper proposes relay selection for multi-destinations in cooperative networks. The study is im- plemented under a security constraint whereby an eavesdropper tries to eavesdrop on information sent from the sender. Hence, we investigate an optimal relay selection technique, in order to improve the level of security in the network by securing information sent to multi-destinations and thereby confusing the eavesdropper. The performance of the proposed system scheme is analysed using average secrecy capacity and outage probability, which are confirmed by numerical results based on simulations.

Index Terms-Relay selection, cooperative networks, secrecy capacity, outage probability, multi-destination.
