Jamming Games for Power Controlled Medium Access With Dynamic Traffic

Due to the broadcast nature of the wireless medium, wireless networks are highly susceptible to jamming attacks. Such attacks are often studied in a game theoretic framework under the assumption of uninterrupted traffic subject to continuous jamming opportunities. The authors analyze the effect of dynamically changing traffic on jamming games for power controlled medium access. Random packet arrivals raise the possibility that the transmitter queues may be empty when jamming attacks start and waste the energy of jammers. They consider a non-cooperative game in which transmitters and jammers select transmission power to balance the transmission cost subject to delay and energy constraints. They show that jammers incur a significant performance loss when they do not have knowledge of the transmitter's queue states.
