Abstract
A performance comparison of relay selection based on the path probability selection of Ant Colony Optimization algorithm (ACO), among dual-hop amplify-and-forward and decode-and-forward relay networks is formulated in this paper. An adaptive power allocation strategy based on Brent’s method has been proposed. The secrecy performance is evaluated in traditional, fading and path loss wireless models. Traditional best relay selection, exhaustive search optimization algorithm and equal power allocation strategy have been derived as schemes for comparison. The effect of number of relays on secrecy is also evaluated. Simulation results reveal the merits of the proposed relay selection and optimization schemes as compared to conventional schemes.
