My research
Research, projects and people
My research interests lie in the broad areas of distributed systems and wireless Internet technologies, including next-generation wireless networks and systems, smart cities and multimedia communications. I develop new algorithms, protocols and solutions that ensure the best user experience, tackling key problems such as mobility and resource management. My current focus is AI for mobile networks, 4G/5G/6G, Wi-Fi 6/7/8, time-sensitive networking, the edge-cloud continuum and adaptive video/XR streaming.
Keywords: 4G, 5G, 6G, software-defined networking (SDN), network function virtualization (NFV), video on demand, live video, quality of experience (QoE), virtual, augmented and extended reality (VR/AR/XR), time-sensitive networking (TSN), edge-cloud continuum, agentic AI, mobile sensory data, big data analysis, performance modeling and optimization.
I am grateful to my research sponsors and collaborators across the world:
