Various Jamming Attacks and Jamming Methodology: A Survey

S. Pushpa Latha and Dr.R. Sabitha

Jamming in wireless networks is defined as the interference in existing wireless communication to decrease the signal to noise ratio at the receiver sides through the transmission of interfering wireless signals. Jamming can be referred as the planned disrupted attack on wireless networks. It is the attempt of the users to not use the networks. Jamming attacks severe Denial-Of –Service attacks against wireless medium. It causes intentional interference in networks which blocks legitimate communication by malicious nodes. For better understanding of this problem, we need to discuss and analyze about the common jamming techniques, the various types of jammers and typical countermeasure against jamming. Various jamming strategies and parameter matrices for different jamming attacks are studied. In this paper we describe open issues such as energy efficient detection scheme, packet delivery ratio, packet sending ratio, End to End delivery, characteristic of jamming attack, and jammer classification. Finally we study about PSR and PDR for the jammer models adapted in different MAC protocol.
