In a tactical field, communicate receiver communication is prevailed among military agents and vehicles, but it is fragile by throng charge from an adversary because of the wireless shared medium. Jamming attack is easily achieved by emitting continuous radio signal and it ass interfere with other radio communications within the network. pathway switching over multiple channels or street detouring have been proposed to restore communication from jamming attacks, but they crave a special radio system or acquaintance of network topology. In this paper, in order to overcome limitations of the previous research, we propose a new robust rate edition 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 level best throughput based on the successful transmission probability.



Through the operation evaluations, we prove rate adaptation scheme that improves packet slant ratio and the wireless link utilization. Keywords: Tactical networks, Jamming attack, Rate adaptation, Multi-hop networks

1. Introduction
C In tactical environments where no infrastructure exists, a wireless MANET (Mobile Ad hoc Network) attracts attention since military agents and vehicles must show a selforganized network to exchange message that supports tactical operations. However, radio communications in the tactical MANET face several redoubted security and reliability contests due to the shared medium. One challenge is jamming [1]. A jamming attack is easily delivered by emitting continuous signal or injecting dummy...If you want to get a full essay, order it on our website: Ordercustompaper.com
