Wireless Multimedia Sensor Networks (WMSNs) have brought unprecedented potentials for applications requiring ubiquitous access to multimedia contents such as still images. However,...
In high energy physics, bioinformatics, and other disciplines, we encounter applications involving numerous, loosely coupled jobs that both access and generate large data sets. So...
In a data intensive Grid system, many data replica schemes and models have been proposed to improve the system response time or data consistency, but little attention has been pai...
This paper explores the feasibility of a cost-efficient storage architecture that offers the reliability and access performance characteristics of a high-end system. This architec...
When spatial objects are replicated at several sites in the network, the updates of a long transaction in a specific site should be propagated to the other sites for maintaining th...
