Dynamicity is an important requirement for critical software adaptation where a stop can be dangerous (e.g. for humans or environment) or costly (e.g. power plants or production lines). Adaptation at run-time is also required in context-aware applications where execution conditions often change. In this paper, we introduce MaDcAr, an abstract model of(More)
Building softwares in a concern oriented fashion can be splited in two main steps : rst de ning each concern separately (or reusing existing ones) and then composing (i.e. integrating) those concerns together. Among existing approaches to support this development scheme, we are interested in re ection. This interest is particularly motivated by the natural(More)
Exploration of an unknown environment is one of the major applications of Multi-Robot Systems. Many works have proposed multi-robot coordination algorithms to accomplish exploration missions based on multi-agent techniques. Some of these works focus on multi-robot exploration under communication constraints. In this paper, we propose an original way to(More)
Component-Based Software Development (CBSD) swears software reuse but it suffers from code scattering and tangling. Aspect Oriented Programming (AOP) deals with these problems. We present in this paper, Fractal-AOP, an add-on to the Fractal component model that combines AOP and CBSD into an overall model. Combining is achieved by applying AOP principles on(More)
In the context of meta-programming and reflective languages, classes can be treated as full fledged objects which are instances of other classes named metaclasses. Metaclasses have proved to be useful for defining new class properties. Examples of such properties are lazy memory allocation, multiple inheritance, having a single instance. . . A class with(More)

Maintaining the network connectivity in mobile Multi-Robot Systems (MRSs) is a key issue in many robotic applications. In our view, the solution to this problem consists of two main steps: (i) making robots aware of the network connectivity; and (ii), making use of this knowledge to plan robots tasks without compromising connectivity. In this paper, we view(More)
A proxy object is a surrogate or placeholder that controls access to another target object. Proxy objects are a widely used solution for different scenarios such as remote method invocation, future objects, behavioral reflection, object databases, inter-languages communications and bindings, access control, lazy or parallel evaluation, security, among(More)
