摘要：Cognitive networks enable efficient sharing of the radio spectrum. Control signals used to setup acommunication and broadcast to the neighbors in their particular channels of operation. This paper deals withbroadcasting challengespecially in multi-hop CR ad hoc networks under practical scenario with collision avoidancehave been address. Exchanging control information is a critical problem in cognitive radio networks. Selectivebroadcasting in multi-hop cognitive radio network in which control information is broadcast over pre-selected set ofchannels. We introduce the idea of neighbor graphs and minimal neighbor graphs to obtain the necessary set ofchannels for broadcast. Selective broadcasting reduces the delay in disseminate control information and yet assuressuccessful transmission of information to all its neighbors. It is also confirmed that selective broadcasting reducesredundancy in control information and hence reduces network traffic.
