Joint Communication and Computational Resource Allocation for QoE-driven Point Cloud Video Streaming
This work addresses the critical demand for efficient point cloud video streaming to improve immersive experiences in fields like online education and entertainment, though it appears incremental as it builds on existing resource allocation methods.
The paper tackles the challenge of streaming large, computationally intensive point cloud videos for VR/AR/MR applications by proposing a resource allocation scheme that maximizes system resource utilization to enhance quality of experience, with simulations showing superior performance over existing schemes.
Point cloud video is the most popular representation of hologram, which is the medium to precedent natural content in VR/AR/MR and is expected to be the next generation video. Point cloud video system provides users immersive viewing experience with six degrees of freedom and has wide applications in many fields such as online education, entertainment. To further enhance these applications, point cloud video streaming is in critical demand. The inherent challenges lie in the large size by the necessity of recording the three-dimensional coordinates besides color information, and the associated high computation complexity of encoding. To this end, this paper proposes a communication and computation resource allocation scheme for QoE-driven point cloud video streaming. In particular, we maximize system resource utilization by selecting different quantities, transmission forms and quality level tiles to maximize the quality of experience. Extensive simulations are conducted and the simulation results show the superior performance over the existing schemes
