We present the initial architecture and implementation of VLab, a Grid and Web-Service-based system for enabling distributed and collaborative computational chemistry and material science applications for the study of planetary materials. The requirements of VLab include job preparation and submission, job monitoring, data storage and analysis, and distributed collaboration. These components ar...

Real-time event stream processing (RT-ESP) applications must synchronize continuous data streams, e.g., infrared scans and video monitoring for survivor detection after a natural disaster, despite fluctuations in resource availability. Satisfying these needs of RT-ESP applications requires predictable QoS from the underlying publish/subscribe (pub/sub) middleware. If a transport protocol is not...

Middleware is necessary for developing distributed systems. Developers compose them from reusable services provided by standard or proprietary middleware infrastructures, including the Object Management Group’s Common Object Request Broker (CORBA), Microsoft’s Distributed Component Object Model, Sun Microsystems’ Java Remote Method Invocation, and related services, to deal with nonfunctional re...

Developers of distributed multimedia applications face a diversity of multimedia formats, streaming platforms and streaming protocols. Furthermore, support for end-to-end Quality-of-Service (QoS) is a crucial factor for the development of future distributed multimedia systems. This paper discusses the architecture, design and implementation of a Quality of Service (QoS) aware middleware platfor...

In smart home environment, different kinds of system components including hardware elements, software components, network connections, and sensors are required to cooperate with each other to reduce environmental burden by energy management and to support human’s life allow for a comfortable lifestyle. This paper proposes a concept of an agent-oriented middleware for smart home that consists of...

VANET is one of the most important parts in smart cities. However, heterogeneous network devices used by different vehicles make data exchange among vehicles become particularly difficult. To solve the problem, a distributed service sharing middleware for VANET called VssOSGi is proposed in the paper. In this middleware, various kinds of functions provided by sensing devices in vehicles are vir...
