On the Retrial-Queuing Model for Strategic Access and Equilibrium-Joining Strategies of Cognitive Users in Cognitive-Radio Networks with Energy Harvesting

This article studies the strategic access of single-server retrial queue with two types customers, where priority is given according to their category. On basis this concept, a cognitive-radio network was developed as energy harvesting. Cognitive radio allows for secondary user opportunistically idle spectrum primary (PU). Upon arrival user, service by cognitive interrupted, and PU band available user. After completion again users. Performance metrics are derived study equilibrium strategies A Stackelberg game formulated Nash noncooperative strategy Game-theory concepts incorporated queuing theory ideas obtain net benefit social cooperative strategy. Lastly, analytical results verified numerical examples, effects energy-harvesting rate discussed.
