Routing In Cognitive Radio Networks: A Detailed Description
Journal Title: International Journal of Computer Science & Engineering Technology - Year 2016, Vol 7, Issue 5
Abstract
The lack of spectrum availability and the need for effective use of the spectrum has led to the novel technology called cognitive radio networks. There are two kinds of users in the network. The primary or licensed users, who make use of the spectrum assigned to them by any governmental agencies. The Secondary or unlicensed users has restricted access to the spectrum. The secondary user is also called as Cognitive user. The basic idea of the cognitive radio network is that the unlicensed or secondary users can make use of the spectrum of a primary user but the secondary user has to vacate the band once the primary user starts transmitting the packets. There is also another option in which the primary and the secondary user can transmit the packets simultaneously. In order to achieve this coexistence, the transmission power of the secondary user must be lesser than a threshold value such that the QoS requirements of the primary user are satisfied.
