Spectrum is the most valuable and scarce resource for every wireless application. Due to the scarcity of the spectrum other alternatives are also being searched. Cognitive Radio (CR) technology is one such alternative which has gained popularity in the recent times. It has been established from various researches that the allocated band is not in use for all the time by the licensed user or as Primary Users (PUs). The Cognitive Radio users also called as Secondary Users (SUs) communicate using unlicensed band or by using the idle licensed band of primary users opportunistically. This paper evaluates the performance of routing protocols by varying concentration level of PU and SU. We have also investigated the impact of time given by PU’s to SU’s for data transfer. For performing the above task, a simulator is designed in MATLAB-7.01. The results show that the performance of routing protocols improves significantly as the number of PUs and allowable time given by PU’s to SU’s increases.
