Abstract :

A cognitive radio network is composed of secondary users, referred to as cognitive users, which are allowed to use a given licensed spectrum in an effective manner, and also band as long as there are no primary (or) licensed, users occupying this band in their neighborhood. This limited spectrum access strategy leads to heterogeneity in spectrum availability among secondary users .The first objective is maximizing the network coverage area, in terms of the total number of clients served, and at the same time reduce the communication coordination function. To address this type of problem, we proposed a received based spectrum allocation strategy that reduces the need for a common control channel, thus reduce the coordination function.
