Randomized Channel Hopping Scheme for Anti-Jamming Communication
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 hopping over multiple channels. However, these solutions require pre-key establishment before data transmission, which in turns introduces several constraints. In order to solve the problem, this paper proposes a novel Quorum Rendezvous Channel Hopping (QRCH) scheme.
