Cooperative communication plays the vital role in cognitive radio network where intermediate nodes are employed as relays. But it is really tough to select the desired or so called the best relay in a multiple-relay cognitive radio system in order to improve the performance of the secondary network while ensuring the quality-of-service (QoS) of the primary network. In this paper we propose a new fuzzy logic-based decision-making procedure for relay selection unlike to many existing works where Signal-to-Interference-plus-Noise Ratio (SINR) is considered as the only parameter for relay selection. The underlying decision criterion considers SINR with some other important parameter like Relative Link Quality (RLQ) of the relay node from destination & Reliability of the relay node. To find out the best relay using our proposed scheme, we have conducted an extensive simulation study. The simulation results reveal the impact of different parameters on selection of Best relay.
