The explosive proliferation of smart devices and cloud computing has ushered the era of Cyberphysical Systems (CPS), a congruence of physical dynamical systems with the cyberspace. The success of deploying an Internet of Things (IoT) interconnecting billions of devices relies heavily upon making the right choices in revisiting traditional architectures for networked control and information processing...
The standard solution for automotive control networks is the Control Area Network (CAN) bus. Almost any vehicular computer system comprehends at least one CAN line. For the past two decades, software development for control system has been strongly connected to the properties and interfaces of the CAN bus. Currently, the automotive industry is in the middle of a technology leap towards an information-based...
Self-protection refers to the ability for a system to detect illegal behaviors and to fight-back intrusions with counter-measures. This article presents the design, the implementation, and the evaluation of a self-protected system which targets clustered distributed applications. Our approach is based on the structural knowledge of the cluster and of the distributed applications. This knowledge allows...
Social robots must adapt to dynamic environments, human interaction partners and challenging new stringent tasks. Their inner software should be designed and deployed carefully because slight changes in the robot's requirements can have an important impact in the existing code. This paper focus on the design and implementation of a lightweight middleware for networked robotics called \textit{Nerve},...
This paper describes a self-configurable middleware and a node execution platform to support autonomous sensor networks. We achieve self-configuration by scheduling and strategies similar to load balancing (mapping) that is integrated in our proposed middleware. On the node execution platform we decide on the fly between microprocessor and FPGA realization of hybrid tasks. We propose a combination...
In the current distributed simulation system, the real-time network transmission has been increasingly demanded. However, the traditional physical shared storage and LAN technology both have some limitations. This paper describes the reflective memory network technology and compares it with the traditional network transmission technology. In the High Level Architecture (HLA) applications, Most of...
Cognitive radio networks are expected to address and resolve important operational challenges such as opportunistic spectrum access, spectrum and network heterogeneities and requests for the provision of diverse Quality-of-Service (QoS) for different applications. Accordingly, a number of network functionalities are required to take into account these challenges towards the efficient management of...
Architectural styles impose constraints on both the topology and the interaction behavior of involved parties. In this paper, we propose an approach for analyzing implemented systems based on the publisher subscriber architectural style. From the style definition, we derive a set of reusable questions and show that some of them can be answered statically whereas others are best answered using dynamic...
While the advances in networking technologies actually enable mobility and ubiquity of access to computing resources located at different administrative domains, the progress in multimedia technologies has created large amounts of digital content that can be purchased and distributed on the Internet. Within this setting, the problem of the copyright protection of digital content has become a well-known...
The SORMSYS project's main goal is to optimize resource management in large scale distributed systems with the capability of self-organization. This paper will present the design of management architecture based on existing middleware solutions through the design of algorithms and methods inspired by natural models. The architecture is full decentralized and it will aim to optimize resource management...
Industrialised societies are increasingly dependent on embedded systems that are getting more and more complex, dynamic, open, while interacting with a progressively more demanding and heterogeneous environment. To manage efficiently the life cycle of applications deployed in such devices, some frameworks like OSGi have emerged. Such frameworks enable flexible applications deployment but in the absence...
Our work provides the specification and implementation of a communication mechanism between broadcast content viewers and interaction devices or sensors placed on the scenario of a live video show. This solution was designed using middleware based architecture and interconnects the devices and sensors of a broadcast program environment in a device network. By using the proposed architecture, the viewers...
Component-based software engineering (CBSE) focuses on the reuse of already available software assets aiming better productivity and quality. By adopting software product line (SPL) practices, an organization is able to develop a family of products, each one targeting a particular market segment or platform. In this context, this paper presents a repository that allows the management of CBSE and SPL...
Remote healthcare monitoring has attracted the interest of many research projects during last years. The need to address the issue of ageing population has lead to the exploitation of modern communication and software technologies in this domain too. This is instigated by related technological evolutions such as the evolutions in sensor networks which can now support self organization. This paper...
Large computing systems including clusters, clouds, and grids, provide high-performance capabilities that can be utilized for scientific applications. As the ubiquity of these systems increases and the scope of analysis performed on them expand, there is a growing need for applications that do not require users to learn the details of high-performance computing, and are flexible and adaptive to accommodate...
An agent-oriented pervasive system supporting a context-aware and personalized mLearning services provision within an InfoStation-based University network is presented. The InfoStation's middleware architecture facilitating the users' mobile (WiFi) access to services is described. The agents' interaction is explained in detail. An extended system architecture supporting the service personalization...
The steady drumbeat of Cloud as a disruptive influence for Infrastructure Service Providers (ISP's) and the enablement vehicle for Software As A Service (SAAS)providers can be heard loud and clear in the industry today. In fact, Cloud is probably at the peak of the hype curve, and already there are identified challenges associated with effective deployment for business critical applications (so called...
Digital Video Content is now pervasive and services like IPTV are gaining traction on hand held devices too. Android, a software platform from Google, pioneering middleware and applications for handheld devices does not offer support for content management services by design. Motivated by these observations, we propose an aggregate model software platform to offer content management and value added...
Until now, high-performance has been the main objective in software for robotics and, as a result, the ad-hoc implementations have been optimized for specific hardware and platforms. Nevertheless, there is a renewed interest in designing robot control architectures to be reusable and maintainable as possible, so that existing software modules can be adapted to new platforms and requirements, thus...
The second generation of the Radar Open Systems Architecture has been developed and put into practice. This approach consists of a layered architecture that isolates applications from underlying hardware and software elements such as operating systems, middlewares, communication fabrics, and computer platforms. The framework also consists of a set of component libraries that are being populated as...
