Abstract
This paper primarily concentrates on Nash bargaining (NB) which is extensively accepted in cognitive radio (CR) network for allocation of resources. The application domains and effectiveness of NB in wireless networks are discussed systematically. Afterward NB is formulated with step by step computation in sharing of resources for a unique scenario. The base station shares the resource of single primary user (PU) with a particular CR subject to constraint imposed by the PU. The utility function is designed that directly reflects the spectrum utilization of CR. The existence and uniqueness of NB solution is verified analytically. The theoretical and simulation analyses are done to find the competence of NB in sharing of resources to CR satisfying the prerequisites of PU. The variation of Jain’s fairness index with the data rate of CR signifies that the NB provides reasonably high-quality resource allocation to CR.
