Efficient uncoordinated FHSS anti-jamming communication
Proceedings of the tenth ACM international symposium on Mobile ad hoc networking and computing, 2009We address the problem of jamming-resistant communication in scenarios in which the communicating parties do not share secret keys. This includes scenarios where the communicating parties are not known in advance or where not all parties can be trusted (e.g., jamming-resistant key establishment or anti-jamming broadcast to a large set of unknown ...

A self-recovery scheme in anti-jamming communications
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002By exploiting the spatial diversity among different signals, anti-jamming communications can be accomplishing using antenna arrays. In this paper, we discuss the self-recovery problem for antenna array wireless systems after the communication link is broken due to abrupt environmental changes.

Dynamic Spectrum Anti-Jamming Communications: Challenges and Opportunities
IEEE Communications Magazine, 2020Due to the openness of the transmission medium, it is necessary for radio systems to have anti-jamming abilities. Traditional anti-jamming methods such as sequence-based frequency hopping and direct sequence spread spectrum have shortcomings of low spectral efficiency and fixed communication patterns.

Randomized channel hopping scheme for anti-jamming communication
2010 IFIP Wireless Days, 2010Jamming attacks have been recently studied as wireless security threats disrupting reliable RF communication in a wireless network. By emitting noise-like signals arbitrarily on the shared wireless medium, a jammer can easily disturb the network. Countermeasures such as Frequency-Hopping Spread Spectrum enable nodes to avoid the jamming attacks by ...

Anti-Jamming Trajectory and Power Design for Cognitive UAV Communications
2021 International Wireless Communications and Mobile Computing (IWCMC), 2021This paper studies the anti-jamming issue for cognitive unmanned aerial vehicle (UAV) communication networks. We aim to maximize the throughput of information collection in sensitive areas or unmanned areas of military borders by optimizing the UAV trajectory and the secondary transmitters (STs)' transmit power, in the presence of malicious jammers ...

Anti-Jamming Communication Game for UAV-Aided VANETs
GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017Vehicular ad-hoc networks (VANETs) are vulnerable to jamming attacks, and frequency hopping-based anti- jamming techniques are not always applicable in VANETs due to the high mobility of the onboard units (OBUs) especially under a large scale network topology.

An anti-jamming framework of spread spectrum communications with ICA
SPIE Proceedings, 2012When jamming signal is strong enough, the performance of spread spectrum (SS) communications will decline quickly. According to the independence between the SS signal and the jamming signal in baseband, a novel anti-jamming framework of SS communication with independent component analysis (ICA) is proposed in this paper.

Randomized positioning DSSS for anti-jamming wireless communications
2016 International Conference on Computing, Networking and Communications (ICNC), 2016Traditional anti-jamming approaches like Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS) require the sender and the receiver to share a secret key prior to their communication. If this key is compromised by the jammer, the jammer can then generate the frequency hopping patterns or the spreading codes used by the ...
