Abstract
In this paper we propose an anti-jamming technique which is based on a secret reallocation of the jammed channels. Jamming is defined to be a deliberate use of radio noise or signals in an attempt to disrupt communications. We present suitable algorithms to be executed by a transmitting and a receiving node, assuming the possible presence adversaries acting as jammers. In our proposed algorithm, for a network with n jammed channels out of m simultaneously active communications, the average number of attempts to find n free channels is equal to ⌈1/f⌉, where f is the fraction of free channels out of total of C channels, and is hence independent of both m and n. Simulation results of our proposed approach on random networks also show that our proposed anti-jamming protocol is quite effective in counteracting jamming attacks.
