Efficient uncoordinated FHSS anti-jamming communication

Proceedings of the tenth ACM international symposium on Mobile ad hoc networking and computing, 2009
We 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 ...

Anti-Jamming Communication Game for UAV-Aided VANETs

GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017
Vehicular 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.

Randomized channel hopping scheme for anti-jamming communication

2010 IFIP Wireless Days, 2010
Jamming 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 ...
