There are two main scalable methods for streaming live video over the Internet: Content Delivery Networks (CDNs) and Peer-to-Peer (P2P) networks. Though both have their own problems, P2P streaming systems challenge delivering video with constant quality and CDNs approaches require deployment of large number of servers throughout the Internet that is costly. Recently, using hybrid architectures based...
Internet-based video streaming applications is becoming more and more popular and attract millions of online viewers every day. The incredible growth of viewers, dynamics of participants, and high video quality-of-service (QoS) requirement pose scalability, availability and low-latency challenges to peer-to-peer (P2P) live video streaming systems. Tree-based systems have low-delay but are vulnerable...
In recent years a number of research efforts have focused on effective use of P2P-based systems in providing large scale video streaming services. In particular, live streaming and Video-on-Demand (VoD) systems have attracted much interest. While previous efforts mainly focused on the common challenges faced by both types of applications, there are still a number of fundamental open questions in designing...
In this paper, we address the problem of collaborative video caching in mobile ad-hoc networks. We consider network portraying static video server with wired interface to gateway node that is equipped with wireless interfaces, other nodes are requiring access to the video streams that is stored at video server. In order to reduce the average access latency as well as enhance the video accessibility,...
How to improve the scalability and QoS of peer-to-peer on-demand streaming system based on unstructured overlay is still a problem. Researchers have proposed some memory based buffering schemes to archive the targets. Considering the limited space of memory on one peer, a new caching strategy, which can integrate memory-caching strategy with disk-caching strategy, is proposed to make full use of peers...
Providing scalable video services in a peer-to-peer (P2P) environment is challenging. In this paper we formulize the QoS (quality-of-service)-aware replication problem for P2P video-on-demand (VoD)systems, the goal of which is to satisfy access time deadlines for all nodes while maximize the probability of the successful block requests. A novel caching mechanism was proposed to achieve the goal, which...
There has been much work on multicast approaches for scalable systems. Periodic broadcasting (PB) is the most effective approach to building large-scale video-streaming services. But, one weakness of PB is the assumption of a homogeneous environment where all clients have the same resources such as reception bandwidth and storage. This assumption about clients is not reasonable in practical situations...
