As the popularity of WebVR applications rises in recent years, a great disparity exists between the huge 3D content on servers and the limited cache capacity on clients. In order to alleviate server loading, peer-to-peer (P2P)-based 3D content distribution has been proposed recently. However, given the limited cache sizes at clients, how to maintain and replace the cache content effectively becomes...
Peer-to-Peer streaming support for 3D content (i.e., P2P 3D streaming) has recently been proposed to provide affordable and real-time virtual environment (VE) content delivery. However, the generally limited client upload bandwidth requires maximal bandwidth utilization for effective streaming. This paper proposes Bandwidth-Aware Peer Selection (BAPS), a peer selection strategy that improves the bandwidth...
Many peer-to-peer-based virtual environment (P2P-VE) solutions have been proposed recently to improve the scalability of distributed virtual environment (VE) systems. By organizing peers to realize neighbor discovery through mutual peer collaboration, P2P-VEs allow systems to scale without additional server provision. Related services such as the real-time delivery of 3D content (i.e., 3D streaming)...
We propose the design of Plug, an application to find and keep contacts with friends within many inter-connected 3D virtual worlds. Users use an instant messenger (IM)-like interface to converse with friends and find new contacts, using a virtual representation of the user's self. It consists of three parts: a plug is an automatous agent / avatar situated at a user's computer that reflects and mimics...
Interactive 3D content on Internet has yet become popular due to its typically large volume and the limited network bandwidth. Progressive content transmission, or 3D streaming, thus is necessary to enable real-time content interactions. However, the heavy data and processing requirements of 3D streaming challenge the scalability of client-server delivery methods. We propose the use of peer-to-peer...
