Abstract :
—In this study, we enhance achievable sum-rate in an ad hoc network consisting of two source-destination pairs and k half-duplex Decode-and-Forward (DF) relays. We assume that two receivers use strong interference cancellation technique and can cancel strong interference. Then, in order to enhance the achievable sum-rate, we propose a novel relay selection scheme that can make Strong and Weak Interference (SWI) at both receivers. Furthermore, in the proposed scheme, we aim to allocate resources fairly among two transmitters. Simulation results show that with the proposed relay selection scheme, SWI can be made with high probability (greater than 0.95 in crowded environments) at both receivers. Also simulations show that by using the proposed scheme, the transmitters achieve sufficient rates and their achievable rates increase linearly with power of relays.
