The Cognitive Radio (CR) technology has evolved in the recent past to solve the problem of wireless networks resulting from the limited available spectrum. The networks employing cognitive radios are termed as Cognitive Radio Ad hoc Networks (CRAHN). These networks employ: Primary Users (PUs) and Secondary Users (SUs), PU is the one that have licensed band while the SU uses the licensed band of PU opportunistically for communication purpose. To have communication in CRAHN, a routing protocol is required. The performance of this protocol depends upon various factors such as: mobility, transmission range, number of nodes deployed and environment. This paper is an effort to measure the efficacy of routing protocol by varying the above mentioned factors. For this purpose we implemented a Cognitive Ad hoc On demand Distance Vector (CAODV) routing protocol in MATLAb-09. Moreover, this paper also shows the advantage of CAODV over the standard protocol AODV.
