Opportunistic Channel-Hopping Based Effective Rendezvous Establishment in Cognitive Radio Networks

摘要: In cognitive radio networks (CRNs), second users (SUs) exploit spectrum holes by accessing multiple channels opportunistically. such a dynamic-spectrum-access network, the SUs equipped with radios have to establish rendezvous on common channel before they are able communicate each other. Due intermittent appearance of primary users’ signals, access opportunistically, which makes problem challenging. This paper focuses blind where neither any central controller nor control is available. Under an opportunistic framework, we propose concept availability measure dynamic feature channels, and study pairwise effective systematically, for simple yet efficient flexible method proposed. We further extend our many-to-one fairness consideration. The performances solutions evaluated via both theoretical analysis extensive simulations.
