A survey of jamming attack prevention techniques in wireless networks

Network security consists of provisions and policies adopted by network administrator to prevent unauthorized access of network accessible resources. Jamming can be viewed as a form of Denial-of-Service attack, whose goal is to prevent users from receiving timely and adequate information. In these attacks, the adversary is active only for a short period of time, selectively targeting messages of high importance. This paper presents a survey of the existing jamming attack prevention techniques. Selective jamming attacks can be launched by performing real-time packet classification at the physical layer. To mitigate these attacks, three schemes that prevent real-time packet classification by combining cryptographic primitives with physical-layer attributes are also presented in this paper.
