Executive Summary

Frequency hopping has been the most popularly considered approach for alleviating the effects of jamming attacks. In this paper, the authors provide a novel, measurement-driven, and game theoretic framework that captures the interactions between a communication link and an adversarial jammer, possibly with multiple jamming devices, in a wireless network employing Frequency Hopping (FH). The framework can be used to quantify the efficacy of FH as a jamming countermeasure. The model accounts for two important factors that affect the aforementioned interactions: the number of orthogonal channels available for use and the frequency separation between these orthogonal bands.
