ABSTRACT: Intelligent Automation, Inc. proposes a game-theoretic framework for the design and analysis of a robust decision making tool for wideband satellite communications that integrates hierarchical spectrum sharing, spectrum sensing, waveform adaptation and active anti-jamming. We capture transmission and sensing delay aspects and asymmetric information structures in a reliable spectrum tracking mechanism. We apply advanced game theory tools to develop efficient transmission decisions in random satellite network environment with dynamic traffic and channel patterns, where PUs and SUs can share the spectrum hierarchically and protect themselves against cognitive jamming. We will develop a delay-centric and reliable spectrum sensing solution under dynamics traffic and channel conditions and possible sensing errors. We will integrate this with a robust game theoretic decision making mechanism to optimize the system performance in random satellite network environment. Going beyond expected utility optimization, we consider random utilities and propose a robust game theoretic solution that can achieve better computational efficiency, convergence, and overall system performance. We will study the performance with respect to heterogeneous spectrum allocation and jamming objectives. We will investigate the feasibility of using of software-defined radios (USRPs) to develop and prototype the proposed system and testing it on IAI"s wireless network emulation platform, RFnest. BENEFIT: The proposed effort has tremendous application potential in military and commercial satellite and space systems to provide spectrum sensing and management with active countermeasures for adaptive RF interference and adversarial jamming. Such tools are directly beneficial to military satellite communications systems with respect to resource allocation, dynamic spectrum management, active anti-jamming, and threat survivability. Our proposed technology can be also used in a wide range of space network environments, including Air Force Space Networks, Air Force Satellite Control Network (AFSCN), and Airborne Networks. This effort also applies to commercial organizations and homeland security. An important group of commercial applications will be tracking, threat detection and anti-jamming for commercial satellites. In addition, proposed system provides new design guidelines for software-defined-radio (SDR) and anti-jamming system development and opens new market opportunities regarding spectrum awareness and cyber security. Another application is airplane management, where our technologies can be used for tracking any abnormal airplanes and preventing terrorist attacks. These techniques already have enormous military, civilian, and commercial applications.
