Final Report: Secure Wireless Network with Full-Duplex Radio
Abstract
This project aims to develop much improved understanding of the potential of full-duplex radio for secure wireless network, and to develop real-time computational methods for power allocation and beamforming to maximize the security of wireless network equipped with full-duplex radio subject to little or no penalty on user experience. We consider the scenario where full-duplex radio is used to provide the first line of defense at the physical layer of wireless network against eavesdropping from enemy. The full-duplex mode in any given fullduplex radio is treated as dynamically switchable (enabled or disabled) according to user's need. The residual self interference in full-duplex radio is fully taken into account in maximization of secrecy capacity subject to rate, power and/or other constraints. We consider cases where social network and wireless network are treated holistically so that human needs are best served. One particular example is where military radio and civilian radio coexist to improve the efficiency in utilizing limited radio spectrum but without compromising security. The network and channel information readily available for communications among radios for common civilian purposes is utilized to provide additional security for communicating sensitive information.
