Abstract

In this paper, we investigate the selection of cooperative relays in a cellular mobile network. We take into account the effect of the resource sharing of each relay by its served users on the relay selection strategy. At first, we propose a novel selection strategy of one cooperative relay considering both Amplify and Forward (AF) and Decode and Forwards (DF) protocols. Then, we extend our study to the case of selection of two cooperative relays in an attempt to improve the spatial diversity gain. The performances of the proposed selection algorithms are analyzed in terms of number of users assisted by cooperation and residual powers at the relays.
