In this paper, the authors propose a novel packet forwarding scheme based on network coding that is resilient to jamming attack in a tactical area. Wireless communication is necessary in a battlefield, but it is fragile to jamming attacks from an adversary because of the wireless shared medium. Jamming attack is easily achieved by emitting continuous radio signals and it can interfere with other radio communications. 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 the network topology. The new scheme exploits packet redundancy of network coding.
