Optimal anti-jamming strategy in sensor networks
2012 IEEE International Conference on Communications (ICC), 2012Wireless sensor networks have been widely applied to various application domains such as environmental monitoring and surveillance. Because of reliance on the open transmission media, a sensor network may suffer from radio jamming attacks, which is easy to launch but difficult to defend.

Anti-jamming Strategies: A Stochastic Game Approach
2015Due to their shared and open-access design, wireless networks are very vulnerable to many malicious attacks, ranging from passive eavesdropping to active interfering. In this paper, using stochastic game modeling we study anti-jamming strategies and their effectiveness against two types of interference attacks: (i) a random jammer, where the malicious ...

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.

An evolved anti-jamming adaptive beamforming network
Genetic Programming and Evolvable Machines, 2011Interference in wireless networks is undesirable, whether it is due to unintentional or malicious causes. Adaptive beamforming is a spatial filtering technique that can prevent jammers from disrupting wireless networks. This paper presents an evolvable hardware (EH) application in which an evolutionary algorithm (EA) is used to configure an adaptive ...

Dynamic Adaptive Anti-Jamming via Controlled Mobility
IEEE Transactions on Wireless Communications, 2013In this paper, the mobility of network nodes is explored as a new promising approach for jamming defense. To fulfill it, properly designed node motion that can intelligently adapt to the jammer's action is crucial. In our study, anti-jamming mobility control is investigated in the context of the single and multiple commodity flow problems, in the ...

A study of GPS jamming and anti-jamming
2009 2nd International Conference on Power Electronics and Intelligent Transportation System (PEITS), 2009The weaknesses of GPS (Global Positioning System) is vulnerable to be jammed, so the study of jamming and anti-jamming of GPS has drawn more and more attention. In this paper, it analyzes the performance of GPS jamming and the anti-jamming of GPS receiver about blanket jamming.

An Improved Radar Anti-jamming Method
2018 IEEE 3rd International Conference on Signal and Image Processing (ICSIP), 2018When the interference enters from the main lobe direction of the radar, the adaptive side-lobe cancellation algorithm will lead to beam distortion, main lobe pointing offset, and affect the detection of the target. This paper proposes a phase-coded signal system.
