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 ...

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.

The Jamming Transition and the Marginally Jammed Solid
Annual Review of Condensed Matter Physics, 2010When a system jams, it undergoes a transition from a flowing to a rigid state. Despite this important change in the dynamics, the internal structure of the system remains disordered in the solid as well as the fluid phase. In this way jamming is quite different from crystallization, the other common way in which a fluid solidifies.

UAV Relay in VANETs Against Smart Jamming With Reinforcement Learning
IEEE Transactions on Vehicular Technology, 2018Frequency hopping-based antijamming techniques are not always applicable in vehicular ad hoc networks (VANETs) due to the high mobility of onboard units (OBUs) and the large-scale network topology. In this paper, we use unmanned aerial vehicles (UAVs) to

The physics of jamming for granular materials: a review
Reports on progress in physics. Physical Society, 2018Granular materials consist of macroscopic grains, interacting via contact forces, and unaffected by thermal fluctuations. They are one of a class systems that undergo jamming, i.e. a transition between fluid-like and disordered solid-like states. Roughly

Fiber Jamming Transition as a Stiffening Mechanism for Soft Robotics.
Soft Robotics, 2020Robots made of soft materials are demonstrating to be well suited in applications where dexterity and intrinsic safety are necessary. However, one of the most challenging goals of soft robotics remains the ability to change the stiffness of body parts to
