Resource management with probabilistic performance guarantees in opportunistic networks

Abstract:
This letter proposes a multi-channel parallel transmission mechanism for channel assignment in cognitive radio (CR) networks. The proposed mechanism enables secondary users (SUs) to effectively utilize the spectrum. The main novelty in our mechanism lies in utilizing the parallel transmission capability of CRs while considering the randomness of their operating environment to provide soft guarantees on the performance of SUs. Simulation results show that utilizing CR’s parallel transmission capability while considering the time-varying nature of their operating environment allows for higher spectrum utilization and more energy saving.
