24 May 2012Models in frequency-hopping-based proactive jamming mitigation for space communication networks
In this paper, we consider a cognitive radio based space communication system in a game-theoretical framework, where
players dynamically interact through wireless channels to utilize the wideband spectrum for their objectives. The
performance indices include data rate, covertness, jamming, and anti-jamming; each of which relate to an effective
signal-nose-ratio (SNR). The game players have different intents and asymmetric and hierarchical information about the
frequency spectrum which are modeled as three different types of players: primary users, secondary users, and hostile
active jammers. We consider the informational asymmetry in two situations: (1) different information sets for friendly
users and jammers and (2) even among the friendly sensors; some sensors may only have partial or little information
about others due to jammed observations. Such an asymmetric information pattern naturally partitions the sensors into
leaders and followers. In our hierarchical anti-jammer approach, a two level approach includes a pursuit-evasion game
and a Stackelberg game. At the higher-level, a non-cooperative pursuit-evasion game is constructed to model the
interactions between jammer and primary users in the frequency-location domains. At the lower level, primary and
secondary users play a dynamic Stackelberg game in the presence of jammers. Theoretical game solutions are provided
to demonstrate the proposed proactive jamming mitigation strategy.
