Bo Han, Associate Professor, Computer Science, College of Engineering and Computing (CEC), and Parth Pathak, Associate Professor, Computer Science, CEC, received funding for the project: “Collaborative Research: NeTS: Medium: Scaling up Multi-user Immersive Content Delivery Over mmWave.” This project is a collaboration with Dr. Feng Qian from the University of Southern California.
Via this project, the researchers aim to overcome the challenge of supporting multiple users with limited network and computing resources.
They will do this by innovating three key dimensions.
First, they will develop an accurate motion prediction model that captures users' collective motion and their interactions, and study how to adapt to changes deviating from training data.
Second, they will leverage mmWave sensing based on FMCW (frequency-modulated continuous-wave) radar to directly incorporate environment reflection profiles into beamforming and mmWave throughput prediction.
Third, they will propose two approaches to scale up at the application layer: hybrid streaming where certain viewers receive 3D content and others consume content live transcoded by the edge and allowing viewers to share a transcoded view.
The team will integrate the above thrusts into a holistic framework and implement it on their mmWave testbed with heterogeneous client devices. They will also conduct extensive evaluations, including field trials with real users.
“This project is vital for enabling high-quality, real-time interactions in immersive environments, and overcoming bandwidth and latency challenges to support large-scale applications in domains such as education, training, and healthcare,” Han said.
The researchers will receive $720,000 from the National Science Foundation for this project. Funding will begin in Oct. 2024 and will end in late Sept. 2028.
