Book Description
Ce mémoire de thèse s'attache aux problèmes d'équilibrage de charge sur les réseaux dynamiques. Un réseau dynamique est un réseau sur lequel certains liens de communication peuvent être perdus ou surchargés. Dans un premier temps, nous introduisons un nouvel algorithme d'équilibrage de charge, puis nous présentons, l'adaptation aux réseaux dynamiques desalgorithmes de premier ordre. Dans un second temps nous nous intéressons aux algorithmes de second ordre. Pour ces derniers, nous définissons une nouvelle contrainte qui garantit la positivité de la charge car la charge d'un système ne peut pas être négative. Suite à cette définition, nous donnons l'adaptation de ces algorithmes aux réseaux dynamiques. Nous illustrons le comportement des deux types d'algorithmes présentés - premier et second ordre - par différentes simulations qui mettent en évidence l'impact du dynamisme du réseau sur leur évolution. Ces simulations nous montrent que les algorithmes de second ordre sont nettement plus sensibles que ceux de premier ordre. Pour finir ce mémoire, une mise en pratique d'un algorithme d'équilibrage de charge sur un problème concret - la résolution d'une équation différentielle partielle - détaille les différentes étapes nécessaires au déploiement d'un algorithme d'équilibrage de charge.

Book Description
This book describes the fundamental aspects of the new generation of electrical distribution grids, taking as its starting point the opportunities that exist for restructuring existing infrastructure. It emphasizes the incorporation of renewable energy sources into the distribution grid and the need for a technological evolution towards the implementation of smartgrids. The book is organized into two parts: the first part analyzes the integration of distributed energy sources into the distribution grid and the impact of these sources on grid operation. After a general description of the general characteristics of distribution grids and renewable energy sources, it then analyzes the economics of electrical energy distribution networks and presents the impact of these sources on grid operation. The second part of the book then analyzes the various functions which allow for safe operation of the grid and realization of the path towards real world application of smartgrids.

Book Description
This book presents the latest research findings, as well as innovative theoretical and practical research results, methods and development techniques related to P2P, grid, cloud and Internet computing. It also reveals the synergies among such large scale computing paradigms. P2P, Grid, Cloud and Internet computing technologies have rapidly become established as breakthrough paradigms for solving complex problems by enabling aggregation and sharing of an increasing variety of distributed computational resources on a large scale. Grid computing originated as a paradigm for high-performance computing, offering an alternative to expensive supercomputers through different forms of large-scale distributed computing. P2P computing emerged as a new paradigm following on from client-server and web-based computing and has proved useful in the development of social networking, B2B (Business to Business), B2C (Business to Consumer), B2G (Business to Government), and B2E (Business to Employee). Cloud computing has been described as a “computing paradigm where the boundaries of computing are determined by economic rationale rather than technical limits”. Cloud computing has fast become the computing paradigm with applicability and adoption in all domains and providing utility computing at large scale. Lastly, Internet computing is the basis of any large-scale distributed computing paradigm; it has very quickly developed into a vast and flourishing field with enormous impact on today’s information societies and serving as a universal platform comprising a large variety of computing forms such as grid, P2P, cloud and mobile computing.
