Relay selection plays a very important role in wireless ad hoc networks. We propose a cooperative diversity protocol as simple and easy to understand with multi-objective cross-layer criterion by considering the condition of source-to-destination (S-D) link and employing amplify-and-forward (AF) relays. The proposed protocol guarantees full diversity based on scalarization of the two-objective criterion with root mean square (rms) normalization to gain fairness. The two objectives include signal-to-noise power ratio (SNR) and load variance. Simulation results show that the proposed protocol gives higher SNR than a single-objective protocol that does not consider the S- D link conditions. The proposed protocol results in an improvement of 3.03 dB in SNR and is likely to result in cooperative diversity configuration involving two parallel relays. In addition, the load variance achieved by applying the proposed algorithm indicates more evenly distributed traffic load.
