This paper investigates the secrecy outage probability of multicast cooperative relay networking in the presence of multi-destination and multi-eavesdropper nodes. The study is carried out in a multicast relay communication scenario whereby multi-eavesdropper nodes attempt to overhear the source message. Most of the previous studies in the field of cooperative communications and relay selection have considered the presence of either a single eavesdropper or a single destination environment. However, in the actual multicast communication scenario, multi-destination and multi-eavesdropper are presented. We therefore consider an optimal relay selection scheme in order to increase secrecy capacity for multi-destinations and to decrease it for eavesdroppers. The performance of the system is analysed using secrecy outage probability in Rayleigh and Rician fading scenarios, and the results are confirmed through Monte Carlo simulations. The proposed model is compared with other cooperative communication scenarios.
