Most existing works on video transmission over wireless multi-hop networks only consider routing as a network layer problem and have been decoupled from application. Traditionally, the multi-path routing protocol selects paths with lower hop counts and discards routes with higher hop counts, which are application-agnostic. However, the paths with minimum hop counts are not always the least delay ones...
Police departments and other law enforcement agencies have integrated a greater number of video cameras into their daily routines. This has introduced with it the problem of moving and processing vast amounts of video data. In this work, we take a look at some of the associated problems and our own attempts to address them. We first analyze the physical network and infrastructure at Temple University's...
Video-on-demand (VoD) service has been explosively growing since its first appearance. For maintaining an acceptable buffering delay, the bandwidth costs have become a huge burden for the service providers. Complementing the conventional client-server architecture with a peer-to-peer system(P2P) can significantly reduce the central server's bandwidth demands. However, the previous works focus on establishing...
Client diversity is one of the main characteristics of wireless networks. Due to channel diversity, multicasting a video stream in a wireless LAN to multiple clients with different channel conditions is a challenging task. A promising approach for such a problem is to use multiresolution video coding (i.e. scalable video coding) with network coding. In this paper, we study a triangular approach for...
Cloud computing is a new computing paradigm that takes all resources as services, and it is not only agile, but also scalable. With the development of cloud computing, video on demand has become one of the most popular applications over the Internet. Currently, there is a trend of using cloud data centers and virtualization technologies to expand large-scale video streaming services with higher quality...
In recent years, some researchers have begun to focus on researching CDN-P2P-hybrid architecture, but most hybrid architectures belong to tightly-coupled hybrid model. Cloud computing era calls for a more open content service mode. In order to construct open service relationship, we propose one novel CDN-P2P loosely-coupled SLA negotiation model. CDN firstly needs to provide an open and standard-based...
Nowadays, faced with heterogeneous, isolated content service systems, people require peering or allied content services. Firstly, we analyze some existing content service hybrid schemes, such as CDN over P2P Architecture and Peering of CDN Architecture. Based on problem statement, we propose A Novel Web Services-based Content Delivery Service Peering Scheme (WS-CDSP), and we describe scheme architecture...
In this paper, we firstly analyze the mechanism of PeerCast as a P2P live streaming steaming solution. An then, based on the shortcoming analysis of tree-based PeerCast, we propose a improved tree-mesh-hybrid scheme-MultiPeerCast, including Multi-thread media transmission, multiple-to-one overlay network reconstruct, optimized buffer design, media retrieving style changing from push mode to pull mode...
Providing scalable streaming media service over the internet is a demanding task nowadays, CDN(Content Delivery Network) and P2P are the main approaches while both have pros and cons. We propose a novel hybrid architecture - PeerCDN to combine the two approaches seamlessly with their inherited excellent features. PeerCDN is a two-layer streaming architecture. Upper layer is a server layer which is...
