Title: Connectivity jamming game for physical layer attack in peer to peer networks,
Abstract: Because of the open access nature of wireless communications, wireless
networks can suffer from malicious activity, such as jamming attacks, aimed at
undermining the network's ability to sustain communication links and acceptable
throughput. One important consideration when designing networks is to
appropriately tune the network topology and its connectivity so as to support
the communication needs of those participating in the network. This paper
examines the problem of interference attacks that are intended to harm
connectivity and throughput, and illustrates the method of mapping network
performance parameters into the metric of topographic connectivity.
Specifically, this paper arrives at anti-jamming strategies aimed at coping
with interference attacks through a unified stochastic game. In such a
framework, an entity trying to protect a network faces a dilemma: (i) the
underlying motivations for the adversary can be quite varied, which depends
largely on the network's characteristics such as power and distance; (ii) the
metrics for such an attack can be incomparable (e.g., network connectivity and
total throughput). To deal with the problem of such incomparable metrics, this
paper proposes using the attack's expected duration as a unifying metric to
compare distinct attack metrics because a longer-duration of unsuccessful
attack assumes a higher cost. Based on this common metric, a mechanism of
maxmin selection for an attack prevention strategy is suggested.
