Component-Based Software Architecture is a promising solution for distributed computing. To develop high quality software, analysis of non-functional aspects of the software properties (also called Quality of Service or QoS) is very important. The UniFrame research project proposes a Unified Component Meta-Model Framework (UniFrame) that includes QoS contracts. A classification of QoS parameter...

Several commercial software allow to model and simulate an architecture at the physical network layer. However, none of them allow simulating the operating scheme of a distributed object architecture. The aim of this article is to propose a methodology based on the DEVS formalism for the modeling and the simulation of distributed object architectures. We extend the classical “Waterfall” softwar...

This paper presents a distributed software system for a wireless sensor network application that remotely monitors the effects of hurricane winds on manmade structures. The software system is divided into three independent segments that are distributed across the Internet to provide real-time collection and transmission of data between wireless remote sensor units and a centralized server. The ...

The advances of parallel and distributed computing demand high-level programming models that support efficient software development and execution. Graphs can effectively represent the logical structures of distributed systems and applications so as to facilitate the programming of distributed applications and support efficient mapping of programs to hardware architecture. This chapter presents ...

The explosive growth of the Web, the increasing popularity of PCs and the advances in high-speed network access have brought distributed computing into the mainstream. To simplify network programming and to realize componentbased software architecture, distributed object models have emerged as standards. One of those models is distributed component object model (DCOM) which is a protocol that e...

This paper presents an approach to distributed condition monitoring systems that offers a reusable software architecture for a class of condition monitoring (CM) applications. The focus of this paper deals with an open software framework for development of CM applications stemming from 1) the Open System Architecture for Condition Based Maintenance (OSA-CBM) specification, which is an architect...

The techniques of meta-modeling and meta-levels have become a mature concept and have been largely used to solve real problems in programming languages, distributed environments, knowledge representation, or data bases. In this article it is shown how the same techniques can be applied in component-based software architecture. It also shown the need to propose mechanisms of reflexivity within t...

To facilitate the design of large-scale, self-adaptive systems, we have developed the Port-Based Adaptable Agent Architecture. This distributed, multiagent architecture allows systems to be created with the flexibility and modularity required for the rapid construction of software systems that analyze and dynamically modify themselves to improve performance. This architecture provides user-leve...

This research paper deals with Distributed Reconfigurable Embedded Control Systems (RECS) which can dynamically follow different behaviors at run-time according to user requirements or any possible evolution in its environment. We optimize a multi-agent architecture for the system in which a Reconfiguration Agent is affected to each device to apply local reconfigurations, and a Coordination Age...
