Abstract
Although a jamming attack is an important problem in Wi-Fi networks, there is no effective solution to this problem yet. In this paper, we propose a new approach to resolve jamming attacks in Wi-Fi networks based on the concept of channel hopping. If we assume that the attacker does not jam all the channels simultaneously, then it might be possible to circumvent a jamming attack by changing the channel. A channel hopping mechanism is designed so that the access point (AP) and a normal user can agree on the next channel with a high probability without pre-sharing of any secret information between the AP and a user node. The proposed scheme is evaluated through experiment in a test bed.
