Recently, peer-to-peer (P2P) networking has been proposed to deliver contents efficiently in Distributed Virtual Environments (DVEs) without overloading servers. Due to the nature of the real-time communications in DVEs, peers should carefully select neighbors and content pieces with prioritization in order to achieve the best streaming quality. In this paper, we proposed a prioritization framework...
To construct various Virtual Environments (VEs) is essential for geographically dispersed users to real-time interact and roam in various virtual worlds(e.g., virtual city, massively multiuser online games). However, this operation has been hindered by the contradiction between explosively growing 3D contents and relatively slower increasing resources (e.g., bandwidth, CPU resource). This work thus...
Recent technical progress on the Internet and virtual reality has enabled the proliferation of distributed virtual environments (DVEs). In a DVE, high-resolution 3D contents may generate huge data, and the peer-to-peer (P2P) streaming takes advantages to carry these huge traffic in a cost-effective manner. In this P2P paradigm, peers can cache and share DVE data cooperatively to reduce server workload...
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...
Now all kinds of 3D virtual worlds have been popular on Internet, but due to gigantic data of virtual scenes and limit network bandwidth, traditional Client/Server based downloading scheme has been bottleneck for a user to construct local virtual worlds swiftly. This paper proposes a parallel delivery scheme for large scale virtual scenes in a two-layer hybrid based P2P(Peer-to-Peer) overlay, in which...
