Performance of Combined RF and non-RF based Energy Harvesting scheme for Multi-Relay Cooperative Cognitive Radio Network

This work presents a novel approach of combined RF and non-RF assisted Energy Harvesting using Opportunistic Relay Selection protocol in Cooperative Cognitive Radio Network. The study of network throughput performance and effective harvested energy has been the main focus of this paper. The influence of various network parameters such as the sensing time, number of relays, energy conversion efficiency, mean power of non-RF sources and Energy Harvesting coefficient on the system performance has been evaluated. Results show that the proposed model outperforms the existing model in terms of network throughput. Also a trade-off has been observed between throughput and sensing time.
