Abstract:
Cognitive radio (CR) techniques can solve radio spectrum scarcity, as is well known. Spectrum sensing helps unlicensed secondary users (SUs) use spectrum holes in cognitive radio networks (CRNs). Full-duplex (FD) spectrum sensing and data transmission can protect a licensed primary user (PU). This paper proposes and analyzes a spectrum sensing and spectrum access strategy. Based on delay tolerance, we consider heterogeneous real-time and non-real-time SU traffic. We address FD sensing’s FAR. Spectrum handoff and call buffering strategies with p-Retry policy buffer and possibly serve SUs that would otherwise be blocked or dropped. A five-dimensional continuous time Markov chain (CTMC) model and queueing theory are used to evaluate the proposed strategy. Numerical results show how spectrum sensing errors affect such CRNs. Retrial policy buffers also increase network resource utilization and decrease blocking and dropping probabilities.
