Web Services using Asynchronous Communication

Asynchronous interactions are becoming more important in the implementation of complex B2B Web applications. This paper addresses correlation and coordination issues involved with asynchronous Web services, by studying different mechanisms and metadata structures for supporting them; in addition, several interaction patterns for building asynchronous computations are discussed, and the trade-of...

Toward Semantic Web Services for Multimedia Adaptation

Universal Multimedia Access (UMA), where users can consume any multimedia resource anywhere at any time, is the driving vision of ongoing ISO/IEC Moving Picture Experts Group (MPEG) standardization efforts. In that context, intelligent adaptation means that before resources are sent over the network, they are prepared according to the client’s device capabilities, the network conditions, or eve...

Parallel Strategies for Multimedia Web Services

This paper describes a parallel data structure used to perform multimedia web searches. The Spatial Approximation Tree(SAT) is the data structure selected to index queries, where the complexity measure is given by the number of distance computed to retrieve those objects close enough to the query. We present some parallel methods for load balancing the work performed by the processors. The meth...

QoS-aware Multimedia Web Services Architecture

Due to the increasing growth of Web Services, Quality of Service (QoS) is becoming a key issue in web services community. Providers and clients need to use QoS-aware architectures to get/ensure end-to-end QoS. The QoS delivery to clients is highly affected by the web service performance itself, by the hosting platform (e.g., Application Server) and by the underlying network (e.g., Internet). Th...
