In a tactical field, wireless communication is prevailed among military agents and vehicles, but it is fragile by jamming attack from an adversary because of the wireless shared medium. Jamming attack is easily achieved by emitting continuous radio signal and it can interfere with other radio communications within the network. Channel switching over multiple channels or route detouring have been proposed to restore communication from jamming attacks, but they require a special radio system or knowledge of network topology. In this paper, in order to overcome limitations of the previous research, the authors propose a new robust rate adaptation scheme that is resilient to jamming attack in a wireless multi-hop tactical network.
