Cooperative networks have been appreciated for their spatial diversity benefits in wireless communications. In this paper a novel scheme of cooperative networks depending on the number and locations of relays in the network. The effect of relay number and locations are investigated by considering energy optimization. First selects the optimal relay from a set of available relays and then uses this "optimal" relay for cooperation between the source and the destination. The simulation-based performance analysis confirms that the cooperative relaying scheme has an advantage of diversity gain thus improving the bit error ratio performance. The simulation results demonstrate that the proposed cooperative relay node selection algorithm can improve performances by achieving the cooperative gain.
