Abstract

Relay selection (RS) and power control are two essential parts in cooperative cognitive relay network. RS is equal to power control in the condition that a relay cooperates with its full power or doesn´t cooperate at all. So the optimal signal-to noise ratio (SNR) value is described as a 0-1 nonlinear programming integer problem (NLIP). In this paper, a multiple relay selection (MRS) scheme based on artificial bee colony algorithm (ABC) is proposed that can fully obtain optimal SNR value. Simulations show the performance of MRS scheme by ABC algorithm is better than that of exhaustive search, single RS scheme and other sub optimal MRS schemes.
