Efficient Anti-Jamming Technique Based on Detecting a Hopping Sequence of a Smart Jammer

Military wireless communications have always been involved in the improvement of secured tactical Communications. However, securing such networks on a battlefield is far from being simple since wireless jamming attack can be easily done by emitting a continuous radio signal. Especially, a smart jammer is able to send back-to-back packets on the detected channel after scanning all of the channels. Finding a perfect way to avoid jamming is a utopia, but one of the well-knownsolutionsto mitigate jamming attacks is a channel-hopping scheme.In this paper, we consider an existing channel-hopping scheme under smart jammer attacks, and propose an efficient anti-jamming technique that canprotect users from jamming attack by finding outthe hopping sequence of a jammer.Through numerical analysis, we show that the proposed anti-jamming scheme can significantly improve the throughput performance.
