Demo: a testbed to evaluate frequency-hopping anti-jamming techniques in ieee 802.11

Abstract

Wireless communication is inherently prone to disruption by interference. Frequency Hopping (FH) can counter interference and promises to enable communication again even in the presence of intentional interference by jammers. Evaluations of this anti-jamming technique and of corresponding strategies are, however, often limited to theoretical or simulation studies. This demo presents an IEEE 802.11 testbed for a practical FH-jammer game: a STA-AP pair synchronously changes channel to evade a (variable) number of reactive jammers, which try block their communications.
