Admission Control Using Stochastic Learning Games in Cognitive Radio Networks

Opportunistic Routing in Cognitive Radio Networks Using Reinforcement Learning

Cognitive radio (CR) technology is rapidly developing these days due to its capability of adaptive learning and reconfiguration. Thus, using Cognitive Radio Networks (CRNs) spectrum efficiency can be increased by allowing the secondary users (SUs) to access the licensed band dynamically and opportunistically without interfering the primary users (PUs). Daniel H. and Ryan W. Thomas, define the C...

Joint Power Control and Admission Control for CDMA Cognitive Radio Networks

Machine Learning Techniques in Cognitive Radio Networks

Cognitive radio is an intelligent radio that can be programmed and configured dynamically to fully use the frequency resources that are not used by licensed users. It defines the radio devices that are capable of learning and adapting to their transmission to the external radio environment, which means it has some kind of intelligence for monitoring the radio environment, learning the environme...

Performance of Joint Admission and Power Control Algorithms for Cognitive Radio CDMA Networks in Shadowed Environment

Cognitive radio network maximizes number of secondary users (SUs) without affecting the service of primary users (PUs). Admittance of SUs is not only affected by the path loss but also lognormal shadowing. In this paper, we have carried out the simulation study of joint admission and power control (JAPC) algorithms: JAPCMRER and JAPC-MSSRA in presence as well as absence of log-normal shadowing....

Medium Access Control in Cognitive Radio Networks

Cognitive radio (CR) is seen as one of the enabling technologies for realizing a new regulatory spectrum management paradigm, viz. opportunistic spectrum sharing (OSS). In the OSS paradigm, unlicensed users (a.k.a. secondary users) opportunistically operate in fallow licensed spectrum on a non-interference basis to licensed users (a.k.a. incumbent or primary users). Incumbent users have absolut...
