The latest advances in the Internet of Vehicle (IoV) networks, and Software Defined Radio (SDR) enabled spectrum sharing between anonymous users. Such enablement raised many concerns in regards to the system’s security and privacy. Therefore, there is a desperate need for transformative solutions to ensure wireless communication security against eavesdropping attacks.

This paper presents a novel Moving-target Defense (MtD) to enhance the channel secrecy capacity in a Decode-and- Forward (DF) dual-phase large network containing K relays and source nodes with multi-antennas operating on different frequencies. Our MtD approach enables multidimensional spatiotemporal diversification for the user’s traffic in cooperative wireless transmission, to obfuscate signal transmission-patterns and data, across the entire spectrum available. In time, we obfuscate the transmitted data by employing real-time …
