Cooperative Multi-Relay Resource Allocation Algorithm in Cognitive Radio Networks
2017
ICIC Express Letters
Cognitive radio (CR) is an effective way to improve the utilization of spectrum resource. This paper focuses on the resource allocation in cooperative multi-relay cognitive radio networks and proposes a cooperative multi-relay transmission algorithm. In the algorithm, secondary users (SUs) work as the relays of a primary user (PU) to cooperate PU transmitting its data. The transmission slot is divided into two sub-slots. In the first slot, the PU chooses suitable SUs and sub-channels to relay
