Most of the wireless network faces the problem of intentional interference attacks that is typically referred as jamming. This intentional interference with wireless transmissions can be used as a platform for mounting Denial-of-Service attacks on wireless networks. Most of the jamming attacks addressed external thread model. In this paper, the authors addressed problem of selective jamming attack in wireless network. In these attacks, the adversary is active only for a short period of time, selectively targeting messages of high importance.
