Jamming-Resistant Collaborative Broadcast in Wireless Networks, Part I: Single-Hop Networks

We propose a collaborative broadcast scheme for wireless networks, which is based on the Uncoordinated Frequency Hopping (UFH) technique and exploits the node cooperation to achieve higher communication efficiency and stronger jamming resistance. In the collaborative broadcast, nodes that already obtain the broadcast message help forward the message to other nodes. Relying on the sheer number of relay nodes, which grows with time surely, our scheme is fundamentally more powerful than most recent attempts for anti-jamming broadcast. Potential applications include emergency alert broadcast and distribution of key system information in the presence of jamming. We provide three relay channel selection strategies for collaborative broadcast, analyze the corresponding successful packet reception rates for both synchronous and asynchronous scenarios, and present the corresponding cooperation gain. Simulation results in a practical setting show that our scheme significantly reduces broadcast delay and energy consumption against the most powerful jamming, - responsive-sweep jamming.
