Mobility Management Strategies in Heterogeneous Cognitive Radio Networks

Mobility management strategies in cognitive radio networks are paramount for seamless operation across different frequency bands and diverse radio access technologies. In order to satisfy mobility management requirements in cognitive radio networks, cross layer optimization and cooperation within a cognitive radio protocol stack is necessary. This paper examines spectrum mobility requirements and solutions suitable for deployment in cognitive radio networks. The requirements for mobility management tasks in cognitive radio networks are described together with mobility management protocol architecture intended to fulfill these requirements.
