Infrastructure-less and energy-limited multi-hop ad- hoc networks are vulnerable to the Denial-of-service (DoS) attacks launched by malicious jammers. In this paper, we propose a power allocation scheme with cooperative anti-jamming strategy to enhance communication reliability against jamming in ad-hoc networks under limited resource. In the proposed anti-jamming strategy, multiple relays are employed to assist the transmission in multiple hops. Under this strategy, we propose the optimal power allocation scheme with the objective of minimizing the outage probability at the destination. We decompose the outage minimization problem into two sub-problems and obtain the near-optimal solution of each sub-problem based on the upper bound of the outage probability. Simulation results demonstrate the effectiveness of the cooperative jamming strategy and the power allocation scheme proposed.
