Fight Jamming With Jamming - A Game Theoretic Analysis of Jamming Attack in Wireless Networks and Defense Strategy

Free registration required

Executive Summary

In wireless networks, jamming is an easily mountable attack with detrimental effects on the victim network. Existing defense strategies mainly consist of retreating from the jammer or rerouting traffic around the jammed area. In this paper, the authors tackle the problem from a different angle. Motivated by the high energy-consuming nature of jamming, they propose their defense strategy to defeat the jammer by draining its energy as fast as possible. To gain an in-depth insight on jamming and to evaluate the proposed defense strategy, they model the interaction between the jammer and the victim network as a non-cooperative game which is proven to admit two equilibria.
