A Multi-Domain Anti-Jamming Defense Scheme in Heterogeneous Wireless Networks

Blog Article

In this paper, we investigate the anti-jamming problem in heterogeneous wireless networks.Although there are many studies on the anti-jamming defense problem in both power domain and spectrum domain, these two important aspects were addressed separately.In this paper, to cope with the jamming attacks flexibly, we study the anti-jamming defense problem from a multi-domain perspective, which includes both power domain and spectrum domain, and a multi-domain anti-jamming scheme (MDAS) is here proposed.To be more specific, a Stackelberg power game is formulated in the power domain to fight against the jamming attacks, and a multi-armed bandit-based channel selection with a channel switching cost and unknown channel availability state information is formulated in the spectrum domain.

Besides, we analyze color touch 7/97 the performance of the formulated Stackelberg power game and derive the optimal power strategy and utility of a legitimate user.In addition, it is proved that the proposed anti-jamming scheme has a logarithmic regret.Finally, extensive simulations are conducted to validate the performance of the proposed MDAS.
