Cognitive radio, as a promising technology, plays an important role in ad hoc network communications, leading to more reasonable and orderly utilizations of wireless spectrum resources. It is not only an opportunity but also a challenge for wireless mobile communications. In cognitive radio ad hoc networks, the non-uniform channel arrays available for secondary users make difficult to the application of broadcasting technologies, concentrating on common channel selection and broadcast collision. In this paper, a probabilistic selective broadcast, called pSB, is proposed, aiming at economy and energy-saving distributed wireless communications. The protocol adopts an intelligent channel selection policy with a probabilistic forwarding strategy to alleviate collisions caused by redundant message exchanges. Consequently, the proposed pSB outperforms other methods in terms of higher message reach rates and fewer broadcast collisions evaluated by simulations under different parameter configurations.
