摘要：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, we propose a new robust rate adaptation scheme that is resilient to jamming attack in a wireless multi-hop tactical network. The proposed rate adaptation scheme detects jamming attack and selects the data transmission mode which has the expected maximum throughput based on the successful transmission probability. Through the performance evaluations, we prove rate adaptation scheme that improves packet delivery ratio and the wireless link utilization.
