Token Based Control Packet Dissemination in Cognitive Radio Network
Zaw Zaw Htike, Choong Seon Hong · 2010
Cognitive radio network is opportunistic spectrum access network and it allows the secondary users to share the licensed bands with primary users or spectrum owners. The spectrum utilization depends on the information exchanging among users. The control information should be exchanged before any transmission is initiated. In this paper, we propose token based control packet dissemination mechanism. Necessary information is embedded in a token. The token is delivered to every secondary user and the user can get the information of all members in the network by capturing the token. This eliminates the need of control packets exchange procedure. I.
