Abstract

Wireless networks dependent on the active nodes which are reciprocally connected to uninterrupted availability of the wireless environment. Any person with a device which transmits and receives radio signals can secretly read those transmitted lines on wireless transmissions and put some bogus information, or stop legitimate ones. The surroundings of wireless medium is exposed to predictable interruption attacks which are referred as jamming. With wireless transmissions this predictable interruption can be used as launch pad for increasing Denial of Service attacks on wireless network. The internal information of procedure specifications and network secrets with challengers can launch low-effort jamming attacks which are difficult to distinguish and oppose. A condition of particular jamming attacks in wireless networks is shown in this paper. At the physical layer by performing real time packet classification the selective jamming attacks can be launched are demonstrated. By combining cryptographic primitives with physical-layer attributes we expand three schemes that prevent real time packet classification in order to moderate these attacks.
