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

Free registration required

Executive Summary

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, the authors 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. Combined effect of path loss and log-normal shadowing on total secondary revenue and blocking probability is presented. Comparison between two algorithms for shadowing and non-shadowing cases has been done on basis of different metrics.
