Outage Probability of the Optimal and Four Optimal Relay Selection in Bidirectional Dual-Hop Half-Duplex Cooperative Wireless Relay Networks

The work in this paper evaluates the outage probability in two-way dual-hop cooperative relay networks for selecting the optimal relay and the best four relays when there are m relays are available by using the channel conditions. We use the probability density function and the cumulative density function of end-to-end signal to noise ratio to derive close expressions for outage probability (OP). Simulation results show the impact on the performance of our system by applying relay selection (RS) strategy when there are different number of relay nodes are available in our wireless network.
