- W3011471025 abstract "Cognitive radio (CR) is in a form of wireless communication in which a transceiver can detect which communication channels are in used up and which are not free, and instantly move into vacant channels merely avoiding occupied ones. This leads to the use of available radio-frequency (RF) spectrum while minimizing interference to other users. Cognitive Radio Network (CRN) is a combination of Licensed and Unlicensed CR users. In this network, licensed user is primary user and unlicensed user is secondary user which opportunistically and dynamically access the frequency channels finding out the current state of the spectrum without interfering with licensed users. Solutions which are proposed still now are not able to deal with the issues occurring with the state: multiple CRN operating without a centralized coordinator leading to coexistence problem of heterogeneous CRN’s.Fairness between CR users is feature that should be considered in heterogeneous/synchronized networks. In this paper decentralized MAC protocol is proposed to solve the unfairness issue. Various Markov chain models are projected for the study of unfairness condition and a medium access control layer approach.Numerical and simulation results of throughput performance of users are presented to verify the proposed solution." @default.
