En dépit des efforts déployés dans le domaine de la mobilité dans le contexte des réseaux maillés sans fil (Wireless Mesh Networks-WMN), la gestion de mobilité souffre toujours d'un manque de recherche. Plusieurs travaux intéressants ont été menés sur ce type de réseaux, dont quelques-uns qui proposent des solutions pour gérer la mobilité des clients. Cependant, souvent ces solutions exigent aux utilisateurs de modifier ou rajouter des modules supplémentaires dans la pile protocolaire de leur équipement. Dans ce ...

Due to the specificities of wireless links (eg, interferences, collisions, and fading), one of the arguments frequently exposed is that only hop-count as a metric is not enough. To overcome this issue, researchers aimed at making the routing layer more aware of the peculiarities of the physical layer. In this paper, we focus on ad hoc routing ...

Malgré le nombre élevé de protocoles de communication destinés aux réseaux sans fil, seule une petite partie a fait l'objet d'une implémentation dans des conditions réelles. En même temps, attendre l'implémentation finale d'une solution afin d'observer son comportement dans une situation réelle peut s' avérer très fastidieux. Dans cet article, nous suggérons d'insérer une phase de prototypage dans le processus de conception de ces protocoles. Ce prototypage s' appuie sur des outils de haut niveau afin d'aboutir à une ...

In this paper, we present a Prot´´ e- 4 plugin based on the RIO (Regularities Inspector for Ontologies) framework, which detects such regularities in ontologies using cluster analysis. The RIO plugin is an open source tool for visualising syntactic regularities in ontologies; the user can load

We argue that such regularities will be able to help to identify parts of the schemas and guidelines upon which ontologies are often built, espe- cially in the absence of explicit documentation. Such analysis can also isolate irregular

The Regularity Inspector for Ontologies (RIO) is a frame- work for detecting such regularities in ontologies using cluster analysis. Detection of syntactic regularities can be used to identify parts of an ontology that have a similar syntactic structure, and could therefore provide an intuition of their

The Locator/ID separation paradigm seems to well fit the requirements for this new Internet Architecture. Among the various solutions, LISP (Locator/ID Separation Protocol), proposed by Cisco, has gained attention due to the fact that it is incrementally deployable. In the present paper we give a short overview on Open-LISP, an open-source implementation of LISP. Beside LISP's basic specifications, OpenLISP provides a new socket-based API, namely the Mapping Sockets, which makes OpenLISP an ideal experimentation platform for LISP, but also other related protocols.

In particular, the Locator/ID Split paradigm, based on the idea of separating the identity from the location of end-systems, is gaining momentum and seems to be the most promising candidate for the future Internet architecture. A critical component of any Locator/ID Split approach, from a performance and resources consumption perspective, as well as from a security point of view, is the cache. The cache is meant to temporarily store mappings, i.e., the bindings between identifiers and locations, in order to provide routers with the knowledge of where to forward packets.Taking as reference protocol LISP (Locator/ID Separation Protocol), the most successful proposal currently under discussion at the IETF, this paper presents a thorough analysis of such a component, including the implications of policies to increase the level of security, b...

How-ever, the impact of this new paradigm on the Internet traffic is yet to be assessed. In this extended abstract, we present a preliminary analysis of TCP performance in the context of Locator/ID separation.
