Jamming-Resistant Collaborative Broadcast Using Uncoordinated Frequency Hopping
IEEE Transactions on Information Forensics and Security
We propose a jamming-resistant collaborative broadcast scheme for wireless networks, which utilizes the Uncoordinated Frequency Hopping (UFH) technique to counteract jamming without pre-shared keys, and exploits node cooperation to achieve higher communication efficiency and stronger jamming resistance. In this scheme, nodes that already obtain the broadcast message serve as relays to help forward it to other nodes. Relying on the sheer number of relay nodes, our scheme provides a new angle for
... des a new angle for jamming counter-measure, which not only significantly enhances the performance of jamming-resistant broadcast, but can readily be combined with other existing or emerging anti-jamming approaches in various applications. We present the collaborative broadcast protocol, and analyze its successful packet reception rate and the corresponding cooperation gain for both synchronous and asynchronous relays for a snapshot scenario. We also investigate the full broadcast process based on a Markov chain model and derive a closed-form expression of the average broadcast delay. Simulation results in both single-hop and multi-hop networks indicate that our scheme is a promising anti-jamming technique in wireless networks.
