Jamming and Replay Packet Attack Detection in Time Critical Wireless Application

In recent few years, the development of digital physical frameworks has grown enormously, because of the fact that, the wireless networking applications has been drawing expansive interest of studies, specifically in the field of Smart Grid. The Digital Physical Frameworks are mainly suitable for the time-critical message transmission in wireless networks. This paper is attributed to the various attacks that are found in the wireless networks, and how these attacks can be detected and prevented in wireless applications. The attacks that we are concentrating are Jamming attack and the Replay attack. The shared and open nature of wireless networks invites the Jamming attacks, which shows the radio obstruction in influencing the system ability. The previous methods that have been proposed till now, are partially successful in detection of these attacks. But the prevention and securing the actual transmitted messages has been the real problem. Thus, we provide a novel method to detect the jamming attacks by use of message invalidation ratios.
