Abstract
In tactical wireless local area networks, jamming attack can easily occur by sending out continuous radio signals. The damage will be serious when the channel frequency is identical. Since wireless channel environment is open to everyone, the perfect solution for jamming attack does not exist. However, a channel-hopping scheme is well known for mitigating those jamming attacks. In this paper, I consider various channel-hopping schemes in order to analyze the throughput and fairness performance under smart jammer attack. Also an analytical model is introduced to evaluate the throughput performances of channel-hopping schemes. After analyzing well known channel-hopping schemes, I propose a simple channel-hopping scheme that can enhance fairness significantly at minimal throughput degradation expense.
