Recently, the demand for wireless networks resources is exponentially increasing over the world.This is because of the large increment in the web-services.In wireless networks, there are limited resources that can be used by different users for their data transmission to achieve their requirements of quality of service (QoS).The limitation of the available resources and the increment of the demands of these recourses lead to spectrum scarcity problem.To overcome spectrum scarcity problem, Federal Communications Commission (FCC) has already started working on the concept of spectrum sharing.In spectrum sharing the spectrum could be shared between both unlicensed (secondary users, SUs) and licensed (primary users, PUs) users, provided the SUs respect PUs rights to use the spectrum exclusively.Cognitive technology is considered as a promising technology for spectrum exploitation dynamically.By integrating the capability of the cognitive technology in the traditional wireless
