It is widely recognized that the Locator/ID Split paradigm fits well the requirements for the new, more scalable, Future Internet architecture. Both the academy and the industry have already produced several technical proposals, with their own peculiarities and merits. However, despite such an effort, it is still unclear, how the Locator/ID Split will be deployed, what are the drivers of its adoption, who will adopt it, and how the adoption process will most likely evolve in time. In this paper, we answer to these questions by presenting an adoption model for the Locator/ID Split paradigm.

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 ...

This is mainly due to the difficulties found during the implementation phase. In this paper, we introduce Warp, a framework for fast prototyping of wireless network protocols. Warp provides a set of simple building blocks that implement common functionalities needed by a wide range of wireless protocols.

Several high performance solutions can be found in the literature, however, they all have the same requirement that refrains them from being widely adopted: they need either modifications or additional modules into the protocol stack of users' equipment. In this paper, we investigate the mobility problem in WMNs and propose a new efficient solution, which does not rely on any modification or additional software on the client side, thus being totally transparent for end-users. In our analysis, we first show the measurements performed on the existing WMN deployed in LIP6, namely MeshDVNet, and highlight the reasons of its poor performance. Then, we describe the design of Enhanced Mobility Management (EMM), our proposal, which does not need any supplementary installation. EMM takes advantage of the existing Neighbor Discovery Protocol (NDP) cache to keep a track of the last client association and uses this information to trigger an update in order to re-route packets. The measurements we performed show how EMM is able to greatly improve performances.

Prawn provides a software environment that makes prototyping as quick, easy, and effortless as possible and thus allows researchers to conduct both functional assessment and performance evaluation as an integral part of the protocol design process. Since Prawn runs on real IEEE 802.11 nodes, prototypes can be evaluated and adjusted under realistic conditions. Once the prototype has been extensively tested and thoroughly validated, and its functional design tuned accordingly, it is then ready for implementation. Prawn facilitates prototype development by providing: (i) a set of building blocks that implement common functions needed by a wide range of wireless protocols (e.g., neighbor discovery, link quality assessment, message transmission and reception), and (ii) an API that allows protocol designers to access Prawn primitives. We show through a number of case studies how Prawn supports prototyping as part of protocol design and, as a result of enabling deployment and testing under real-world scenarios, how Prawn provides useful feedback on protocol operation and performance.

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 ...

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.

In order to exploit all the advantages that the wireless medium offers, new routing metrics must be explored. These metrics should come from a cross-layer approach in order to make the routing layer aware of the local issues of the underling layers. In the present paper, we explore three primitive physical layer parameters: Interference, Packet Success Rate, and Data Rate. We define the metrics so that the routing level can correctly find paths that offer: low levels of generated interference, reliability in terms of Packet Success Rate, and highest available transmission rate. We prove that for cross-layer based routing, if the metrics are well designed, the problem is NP-Complete.
