From the analysis of some hard drawbacks faced server-centric VOD system today, a novel P2P-based VOD system using media file segments selecting algorithm (P2P-VOD- FSS), is introduced in this paper. In this infrastructure, we emphasize on how to real-timely and orderly download and consume file segments from multiple peer nodes to guarantee streaming service, we firstly give a system model of selecting...
Publish/subscribe (pub/sub) systems are very suitable for the dissemination of dynamic information over the Internet. As dynamic information is usually characterized by a short lifetime, both publishers and subscribers may specify the delay requirement on message delivery. Although existing pub/sub systems can easily be extended so that publishers and subscribers can specify their delay requirements,...
Peer-to-peer (P2P) systems are characterized by direct access between peer computers, rather than through a centralized server. File sharing is the dominant P2P application on the Internet, allowing users to easily contribute, search and obtain content. P2P systems can be categorized by the degrees of centralization. For fully centralized systems, the lookup service will not be available when the...
Radio frequency identification (RFID) is expected to be widely used in the future, as it can be embedded into everyday items as RFID tags. Using RFID technology, enterprises can share real-time data about products with trade partners over the Internet. Application service provider (ASP) provides services for clients in a central managing way by Internet. Users who subscribe the ASP service do not...
On analysis of the drawbacks of the current content delivery system, such as heterogeneous, isolated content service systems and difficult integration, a novel Web services-based content alliance broker scheme - WS-CABroker, is introduced in this paper. Firstly, we propose the architecture of WS-CABroker for integrating heterogeneous content service systems based on Web services standard. Then we...
The link structure of the Web graph is used in algorithms such as Kleinberg's HITS and Google's PageRank to assign authoritative weights to Web pages and thus rank them. Both require a centralized computation of the ranking if used to rank the complete Web graph. In this paper, we propose a new approach based on a Layered Markov Model to distinguish transitions among Web sites and Web documents. Based...
Advances in mobile agent research have brought in a new method for network routing, ant routing. Recently, we have derived some preliminary results regarding the agent population growth property and the jumping behavior for an ant routing algorithm. The focus was on the expected number of agents in a node. In practice, the number of agents propagating on each network channel is also critical as the...
