An overview of security issues in cognitive radio ad hoc networks

Abstract

Cognitive radio ad hoc network (CRAHN) is an emerging discipline of network computing. It combines the advantages of cognitive radio networks and mobile ad hoc networks. This chapter starts with an overview of various research issues of CRAHN along with representative solutions for these research issues. Among the various research issues presented, security is discussed in detail due to its prime importance. A review of existing literature reveals that not much work on security has been reported for cognitive radio networks. Specifically, an overview of security issues in CRAHN, presented in this article, is a novel work of this kind. A major part of this article highlights the importance of security in CRAHN and presents an overview of major security issues and the solutions proposed to address these issues in CRAHN.
