In wireless multi-hop networks, broadcasting by flooding generates frequent retransmissions of unnecessary packets that participate heavily in increasing contention and collision probability. These problems become increasingly likely in a wireless mesh network which can interface to other external networks, thus leading to a significant increase in(More)
The notion of competence and learner model is the kernel of the Competency-Based Approach (CBA). However, as of today there is not a commonly learner model or ontology for competencies, we have presented in this paper our ontology-based representation in order to define the CBA. This representation provides a baseline for an e-learning adaptive system in(More)
An important part of education is student's learning. Good quality education is based mainly on how well student attain the knowledge. One way to achieve that is to simplify the content and make it as intuitive as possible. This can be challenging especially for introductory computer science courses for non-computer science students. Such courses are(More)
E-learning is not restricted to publishing online content. The challenge is to apply pedagogical models using new information and communication technologies in order to adjust the learning process. This adaptation will take place by proposing an adaptive learning system. There are several e-learning environment adaptation approaches such as adaptive(More)
We describe a new temporal verification framework for safety and robustness analysis of nonlinear control laws, our target application being a space launcher vehicle. Robustness analysis, formulated as a nonconvex nonlinear optimization problem on admissible trajectories corresponding to piecewise polynomial dynamics, is relaxed into a convex linear(More)
Wireless mesh networks have seen a real progress due of their implementation at a low cost. They present one of Next Generation Networks technologies and can serve as home, companies and universities networks. In this paper, we propose and discuss a new multi-objective model for nodes deployment optimization in Multi-Radio Multi-Channel Wireless Mesh(More)
With the growing need for service oriented architecture and the rise of cloud computing, web services have become the focus of many researchers and software developers. Our area of focus is web service composition. In this paper we are presenting an evaluation and analysis of the proposed orchestration algorithm in [1]. The algorithm is intended to(More)
Wireless mesh networks have seen a real progress because of their implementation at a low cost. Thus, the planning of such networks presents many challenges for network operators. Our aim in this paper is to provide a new solution to the planning problem using a multi-objective optimization approach. Refer ences I. F. Akyildiz, X. Wang, and W. Wang,(More)
