Abstract
Jamming is a serious security problem in wireless networks. Recently, software-based channel hopping has received attention as a jamming countermeasure. In particular, proactive, or periodic, channel hopping has been studied more extensively than reactive hopping. In this paper, we address the question of which of the two defense strategies, namely proactive and reactive channel-hopping, provides better jamming resiliency than the other? in the context of single- and multi-radio wireless devices. In the single-radio context, we develop theoretical models to analyze the blocking probability for combinations of defense and attack strategies. In the multi-radio setting, we formulate the jamming problem as a max-min game and show through simulation that the game outcome depends on the payooff function. Our results show that reactive defense provides better jamming tolerance than proactive when considering communication availability. However, both reactive and proactive defenses have almost the same performance when energy efficiency is considered as a performance metric.
