Abstract
Cognitive Radio (CR) technology and its capabilities are being explored for their application in military communication networks. Defence Advanced Research Projects Agency (DARPA), USA has conducted successful trials and initiated future programmes for military applications based on CR. Though CR technology is innovative, it is more susceptible to interference and jamming attacks, due to its nature of sensing and adaptive switching. Hence, the performance analysis of Cognitive Radio under jamming conditions is an important requirement and a subject for a new area of research. Development of effective Anti-jamming approaches require in-depth knowledge on jamming techniques and their effects. In this paper, various jamming threats on Cognitive Radio Networks (CRN) are presented based on literature survey, research carried out in various universities and defence research organisations.
