INTELLIGENT SPECTRUM HANDOVERS IN COGNITIVE RAD...

This book highlights the need for an efficient Handover Decision (HD) mechanism to perform
switches from one network to another and to provide unified and continuous mobile services that
include seamless connectivity and ubiquitous service access. The author shows how the HD
involves efficiently combining handover initiation and network selection process. The author
describes how the network selection decision is a challenging task that is a central component
to making HD for any mobile user in a heterogeneous environment that involves a number of
static and dynamic parameters. The author also discusses prevailing technical challenges like
Dynamic Spectrum Allocation (DSA) methods  spectrum sensing  cooperative communications 
cognitive network architecture protocol design  cognitive network security challenges and
dynamic adaptation algorithms for cognitive system and the evolving behavior of systems in
general. The book allows the reader to optimize the sensing time for maximizing the spectrum
utilization  improve the lifetime of the cognitive radio network (CRN) using active scan
spectrum sensing techniques  analyze energy efficiency of CRN  find a secondary user spectrum
allocation  perform dynamic handovers  and use efficient data communication in the cognitive
networks.Identifies energy efficient spectrum sensing techniques for Cooperative Cognitive
Radio Networks (CRN) Shows how to maximize the energy capacity by minimizing the outage
probability Features end-of-chapter summaries  performance measures  and case studies.
