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