Abstract :

In the wireless networks the wireless medium leaves it vulnerable to premeditated meddling attacks, typically eferred to as jamming. This premeditated meddling used in wireless transmission for Denial–of–Service on wireless networks. Fundamentally jamming has been addressed under external threat model. We proposed the problem of internal threat model. In the internal threat model the jammer with awareness of protocols and network secrets can perform low–effort jamming attacks. These attacks are difficult to discover and counter. In this paper, we propose the badly–behaviours of selective jamming attacks and also the jammer is active only for a short period of time and selectively targeting messages of high importance. We show that selective jamming attacks can be launched by performing real–time packet classification at the physical layer. To mitigate these attacks, we develop four schemes that prevent real–time packet classification by linking encrypting methods with physical–layer attributes.
