A Novel Physical Channel Characteristics-based Channel Hopping Scheme for Jamming-resistant in Wireless Communication

Jamming is an effective denial-of-service (DoS) attack in wireless networks due to the open nature of radio propagation. In Jamming attack, the attacker purposely emits radio signals to corrupt the ongoing communication between the legitimate transmitter and receiver. Channel hopping is a feasible link-layer method for preventing jamming attack in wireless communications. In this paper, we propose a novel channel hopping scheme for jammingresistant in wireless communication. In our proposed scheme, we explore the reciprocity, randomness and spatial uncorrelation of the wireless fading channel to generate random channel hopping sequences. We evaluate our channel hopping scheme through real-world experiments on 802.11a 5 GHz band. Experiment results show that our scheme is efficient and secure, and achieves higher channel agreement ratio with almost equally channel distribution.
