Distributed Channel Selection Protocol for Single-Hop Transmissions in Cognitive Radio Networks

We propose a distributed channel selection protocol for cognitive radio networks that are organized as ad hoc architectures considering single hop transmission. The channel selection is performed over a common control channel in such a way that channel congestion as well as heavy sensing effort is avoided. Simulation results show that the proposed protocol significantly outperforms a random channel selection protocol. Categories and Subject Descriptors C.2.2 [Network Protocols]
