Abstract: An opportunistic relay selection based on instantaneous knowledge of channelsis considered to increase security against eavesdroppers. The closed-formexpressions are derived for the average secrecy rates and the outageprobability when the cooperative networks use Decode-and-Forward DF orAmplify-and-Forward AF strategy. These techniques are demonstratedanalytically and with simulation results.
