Incremental Relaying Transmissions with Relay Selection in Cognitive Radio Networks

In this paper, the authors investigate and evaluate the performance of incremental relaying and relay selection, when used in the context of cognitive radio networks. Assuming that a number of cognitive radio relay nodes N (N-2) are co-located with simultaneous primary and secondary transmissions, the "Best" relays are chosen to assist the primary and/or the secondary transmissions (in case of decoding failure at the destinations using the direct link source-destination). The outage probability of both primary and secondary systems is investigated and the associated power allocation problem analyzed.
