Mobile Computing Lab.

Research Themes

With cyber-physical systems (CPS) at our core, we explore technologies that contribute to the development of cities, people, and communities. Our laboratory organizes research around five application domains (Smart City & Building, Smart Mobility & Transportation, Disaster Management, Space & Satellite Technologies, and Intelligent Environment) and three foundation technology layers (System Foundation, Communication & Computing Foundation, and Data Processing & Analysis Technologies). By integrating real-world sensing data with computational capabilities in cyberspace, we develop next-generation systems utilizing cutting-edge communication technologies (Beyond 5G/6G), edge computing, and AI/machine learning. We actively engage in industry-academia collaborations and international joint research, pursuing practical research activities with an eye toward social implementation.
