This paper presents a framework designed to work with a multi platform approach over two levels of definition of an embedded system built from software components. In the upper level, the framework focuses on the composition of components and the ...

Implementing embedded software systems involves many important design decisions, such as finding (near) optimal component deployment architectures, that have a strong influence on the quality of the final system perceived by its users. These decisions ...

Component-based middleware, such as the Lightweight CORBA Component Model, are increasingly used to implement large-scale distributed real-time and embedded (DRE) systems. In addition to supporting the quality of service (QoS) requirements of individual ...

Component-based software engineering provides for developers the ability to easily reuse and assemble software entities to build complex software. Component-based specification of software functional characteristics has been and is largely addressed, ...

In some industrial domains, it is beneficial to model systems that are both data-driven and control-driven. The challenge to component-based development is to provide suitable component models for this purpose. In this paper we propose such a component ...

Separation of concerns is an important aspect of component-based development (CBD), and managing data is a primary concern in enterprise systems. In CBD methods, such as Catalysis and UML components, this concern is addressed by business components. ...

Systems-of-Systems (SoS) are complex infrastructures, which are characterized by a wide diversity of technologies and requirements imposed by the domain(s) they target. In this context, the software engineering community has been focusing on assisting ...

Recommender systems constitute a new field that provides nowadays an important support for information search from huge amounts of data, since some of those information may be of interest of users but hard to be searched manually. According to forecasts,...

Automating the construction of secure distributed systems becomes necessary. Indeed, developing security code requires a deep expertise and verifying that the developed code respects the specified policy is a tedious task. In this paper, we define a ...

It is nowadays widely accepted that extra-functional properties (EFPs) are as important as functional properties for system correctness, especially when considering systems such as safety-critical embedded systems. The criticality and resource-...

As software complexity increases in embedded systems domain, component-based development becomes increasingly attractive. A main challenge in this approach is however to analyze the system's extra-functional properties (such as timing properties, or ...

Designing component-based systems (CBS) that exhibit a good trade-off between multiple quality criteria is hard. Even after functional design, many remaining degrees of freedom of different types (e.g. component deployment, component selection, server ...

Component based software engineering aims at re-using components in other systems. This requires a verification whether the component can safely interact with its communication partners in a new environment. Such verification is mandatory in case of ...

Software components are increasingly assembled from other components. Each component may further depend on others, and each may have multiple active versions. The total number of configurations --- combinations of components and their versions --- ...

To take advantage of component-based software engineering, software designers need a component framework that automates the assemblage and integration of developed components. It is then of prime importance to ensure that the synthesized code respects ...

Orphan requests are a significant problem for multi-tier distributed systems since they adversely impact system correctness by violating the exactly-once semantics of applications and may waste resources. Orphan requests stem from the failure(s) of non-...

We focus on reliability analysis for systems designed as workflow based compositions of components. Components are characterized by their failure profiles, which take into account possible multiple failure modes. A compositional calculus is provided to ...

Exception handling is a practical and important way to improve the availability and reliability of a component-based system. The classical code-level exception handling approach is usually applied to the inside of a component, while some exceptions can ...

Module systems have been acknowledged as software development and maintenance boosters. Likewise, dynamic updating, meaning the ability to evolve a software system at runtime, not only has the potential to increase developer productivity, but also to ...

Software distributions in the FOSS world rely on so-called package managers for the installation and removal of packages on target machines. State-of-the-art package managers are monolithic in architecture, and each of them is hard-wired to an ad-hoc ...

When evolving component based systems, possible side effects can bemitigated by changing only what is necessary. Identifying this minimal change is non-trivial, and exploring different heuristics used for this is the focus of this paper. We look at ...

In this paper we present a model-based approach to tackle the fragility pointcut problem that occurs in Aspect Oriented Systems. We focus on evaluating our work aiming at demonstrating that the definition of model-based pointcuts at early stages of the ...

Today, embedded systems are more and more involved in the definition of new and emergent functionalities of the vehicles and are developed by different component providers. This heterogeneity of origins complicates the integration and the validation of ...
