Abstract
In the recent times, usage of mobile devices has been increased many fold. So, this is very serious problem in wireless communications. This leads to inaccessibility to the mobile services. If this is the situation in today's scenario then in future it would be more hard to provide valid access to all the users simultaneously. Cognitive Radio is a future technology to provide worldwide roaming to improve connectivity and also to have worldwide roaming and interoperability the "cognitive radio" concept was coined. In this proposed paper, a scheme including power allocation scheme and a prioritization scheme is used to achieve higher capacity with the same power. This is done by utilizing a simulated cognitive radio scenario.
