Computer-centered services and broadband wireless connectivity have boosted the demand for delivery of multimedia-based entertainment from the Internet to in-house wireless appliances. In this context, rich-media applications can be supported by a variety of protocols, each sharing the same bottleneck, affecting one another's performance. Indeed, in current systems, real-time applications (e.g., video...
With the increase of network bandwidth, more and more new applications such as audio, video and online games have become the main body in network traffic. Based on real time considerations, these new applications mostly use UDP as transport layer protocol, which directly increase UDP traffic. However, traditional studies believe that TCP dominates the Internet traffic and previous traffic measurements...
Most of future digital services for home and office users will be deployed and delivered through the Internet and wireless connectivity. However, employing regular access points (APs) and protocols will not allow an efficient coexistence among heterogeneous application flows. Indeed, real-time and elastic applications are (and will be) supported by different protocols and featured with different performance...
The presence of high-volume file-sharing activity on the Internet has caused reconsideration of purely flat-rate pricing for bandwidth in some access networks through the use of dynamic differential service priorities for protocol-agnostic (application-neutral) congestion control. We study how BitTorrent-style file-sharing depends on flat-rate pricing. A simple deterministic game-model of BitTorrent...
Peer-to-peer (P2P) media streaming quickly emerges as an important application over the Internet. A plethora of approaches have been suggested and implemented to support P2P media streaming. In our study, we first classified existing approaches and studied their characteristics by looking at three important quantities: number of upstream peers (parents), number of downstream peers (children) and average...
Datasets of tens of gigabytes are becoming common in computational and experimental science. Providing remote visualization of these large datasets with adequate levels of quality and interactivity is an extremely challenging task, particularly for scientists who collaborate in widely distributed locations and their primary access to visualization resources is a desktop computer. This paper describes...
The increased availability of mobile broadband connec- tions enables the expansion of software downloads to mobile devices. This leads to greater number of available services and a better utilisation of the computational power of mobile devices. The downside of this increased software availability is an increase in the possible attack vectors. One scenario is the misuse of resources, for example,...
