Повний текст джерелаLarge-scale deployment of IEEE 802.11 wireless LANs (WLANs) remains a significant challenge. Many access points (APs) must be deployed and interconnected without a-priori knowledge of the demand. We consider that the deployment should be iterative, as follows. At first, access points are deployed to achieve partial coverage. Then, usage statistics are collected while the network operates. Overloaded and under-utilized APs would be identified, giving the opportunity to relocate, add or remove APs. In this thesis, we propose extensions to the WLAN architecture that would make our vision of iterative deployment feasible.
One line of work focuses on self-configuration, which deals with building a WLAN from APs deployed without planning, and coping with mismatches between offered load and available capacity. Self-configuration is considered at three levels. At the network level, we propose a new distribution system that forms a WLAN from a set of APs connected to different IP networks and supports AP auto-configuration, link-layer mobility, and sharing infrastructure between operators. At the inter-cell level, we design a load-balancing scheme for overlapping APs that increases the network throughput and reduces the cell delay by evenly distributing the load. We also suggest how to reduce the handoff time by early detection and fast active scanning. At the intra-cell level, we present a distributed admission control that protects cells against congestion by blocking stations whose MAC service time would be above a set threshold.
Another line of work deals with self-deployment and investigates how the network can assist in improving its continuous deployment by identifying the reasons for low cell throughput. One reason may be poor radio conditions. A new performance figure, the Multi-Rate Performance Index, is introduced to measure the efficiency of radio channel usage. Our measurements show that it identifies cells affected by bad radio conditions. An additional reason may be limited performance of some AP models. We present a method to measure the upper bound of an AP’s throughput and its dependence on offered load and orientation. Another reason for low throughput may be excessive distance between users and APs. Accurate positioning of users in a WLAN would permit optimizing the location and number of APs. We analyze the limitations of the two most popular range estimation techniques when used in WLANs: received signal strength and time of arrival. We find that the latter could perform better but the technique is not feasible due to the low resolution of the frame timestamps in the WLAN cards.
The combination of self-configuration and self-deployment enables the autonomic operation of WLANs.

Повний текст джерелаIn the next generation of wireless communication systems, there will be a need for the rapid deployment of independent mobile users. Significant examples include establishing survivable, efficient, dynamic mobile communication for tactical Special Operation Force (SOF) networks, as well as SOF units that are ad hoc networking with first responders conducting emergency/rescue and disaster relief operations. Such network scenarios cannot rely on centralized and organized connectivity, and should instead employ applications of newly developing Control Based Mobile Ad Hoc Networking (CBMANET). In a CBMANET environment, an autonomous collection of mobile users communicate over relatively bandwidth constrained wireless links by taking benefit of nodes mobility and topology control in combination with mobile platform switching. The network is decentralized. All network activity, including discovering the topology and delivering messages, must be executed by the nodes themselves (i.e., routing functionality will be incorporated into mobile nodes). Harnessing the tremendous flexibility and efficiency of CBMANET would allow for better control and protection of ad hoc mobile networks. Therefore, we need to work tirelessly to improve our capabilities in the three aforementioned control spaces.

Повний текст джерелаEn parallèle avec le développement des services multicast dans l'Internet, la dernière décennie a vu l'émergence des réseaux ad hoc, grâce à l'apparition de nouvelles technologies sans fil et de nouvelles normes (par exemple 802.11, Wimax, ...). Un réseau ad hoc est une collection dynamique de dispositifs, autonomes, reliés sans aucune infrastructure fixe, qui peut être fortement mobile.
La combinaison d'un environnement ad hoc avec des services multicast à déployer, a induit de nouveaux défis envers l'infrastructure de sécurité requise pour un large déploiement des communications multicast dans un tel environnement. C'est dans ce cadre que nous avons défini deux protocoles de gestion de clé de groupe dans les MANETs, un protocole orienté récepteurs, appelé Enhanced BAAL et un protocole orienté sources, dénommé BALADE. Nous avons également proposé OMCT : un algorithme de clusterisation dynamique du groupe multicast, que nous avons intégré dans BALADE. Ce couplage assure une distribution de clés efficace et rapide, tenant compte de la mobilité et de la localisation des nœuds, tout en optimisant la consommation de l'énergie et de la bande passante. L'applicabilité de BALADE couplé avec OMCT est démontrée à travers sa validation formelle avec l'outil AVISPA, son implantation dans le cadre d'une application de Jukebox coopérative, et l'évaluation de ses performances avec l'outil de simulation de réseaux NS2.

Повний текст джерелаEn los últimos años, el campo de las comunicaciones aeronáuticas ha experimentado un incremento masivo de los intercambios de datos entre plataformas terrestres, aéreas y satelitales. Los métodos de comunicación aeronáuticos convencionales han demostrado no ser suficientes para manejar esta demanda creciente. Como resultado, los sistemas aeronáuticos han tendido hacia el uso de comunicaciones vía satélite, que aunque efectivas, suponen un reto económico tanto en su instalación como en su uso. En respuesta a este problema, el trabajo académico en esta área ha propuesto el uso de alternativas basadas en redes de comunicación en la forma de redes aeronáuticas ad-hoc. Estas redes usan alcances de comunicación inmensos y trabajan bajo la premisa de las Redes Ad-Hoc Móviles (MANETs) requiriendo la existencia de conectividad extremo a extremo para su correcto funcionamiento. Las redes aeronáuticas tienen una topología extremadamente variable juntamente con enlaces de comunicación poco fiables. Con estas propiedades en mente, creemos que asumir conectividad de red es una elección desafortunada. Por tanto, en esta tesis intentamos solucionar estos retos utilizando un enfoque diferente. Específicamente, intentaremos establecer una red de aviones sin asumir garantías de conectividad, enlaces de radio cortos y utilizando tan solo los encuentros esporádicos entre nodos para realizar intercambio de datos. Este enfoque oportunista ofrece una alternativa más barata que aquellas basadas en enlaces de radio de largo alcance o en comunicaciones vía satélite. Los fundamentos de esta propuesta se basan en las redes oportunistas, y eventualmente se unen con la tendencia actual de utilizar enlaces vía satélite, para ofrecer una nueva arquitectura de red que reduce ampliamente los costes de comunicación y equipamiento. Las principales contribuciones de esta tesis son las siguientes. Por un lado, el uso de un modelo de movilidad preciso describiendo patrones aeronáuticos basados en información y horarios de vuelo reales. Además, este trabajo utiliza un modelo minucioso para describir las capacidades de red de los nodos incluyendo la representación completa de todas las capas de red. Estas características realistas son muy importantes para asegurar el correcto despliegue en redes reales. Por otro lado, esta tesis ofrece una serie de garantías en la calidad de servicio que son difíciles de obtener en redes oportunistas. Hasta donde sabemos esta tesis representa el primer estudio detallado de una red aeronáutica a gran escala utilizando comunicaciones oportunistas.
In recent years, the aeronautical communications field has experienced increased demand for data exchanges between terrestrial, aerial and satellite platforms. Conventional aeronautical communications have proven to fall short on handling this growing demand. As a result, aeronautical systems have moved towards the use of satellite-based communications, and while effective, their deployment and later use poses an economical challenge. To deal with this problem, academic work on the topic has proposed the use of networking alternatives in the form of Aeronautical Ad-hoc Networks. These networks use large radio communication ranges and work on the premises of Mobile Ad-Hoc Networks (MANET), requiring end-to-end connectivity to function properly. Aeronautical networks have an extremely varying topology coupled with a frequently unreliable communication channel. With this in mind, we think that assuming full network connectivity is a problematic choice. Therefore, in this thesis we will approach those problems using a different method. Specifically, we will strive to establish a network of aircraft assuming no guarantees for connectivity, limited radio ranges, and relying solely on the sporadic encounters between nodes to perform data exchanges. This opportunistic approach offers a cheaper solution than those based on long-range radio links or satellite communications. The foundation of this proposal lies in opportunistic networks, and eventually merges with the current communication trend based on satellite links, to provide a new network infrastructure that greatly minimizes communication costs and equipment expenditure. The main contributions of this thesis are as follows. On one hand, the use of an accurate mobility model describing aeronautical patterns by considering on flight route and scheduling information of real flights. Additionally, this work provided accurate modeling of the network capabilities of each node including the complete representation of all layers of the network stack. These realistic features are of severe importance to ensure successful deployment in real networks. On the other hand, this thesis provides Quality of Service assurances that are hard to achieve in opportunistic networking. To the best of our knowledge, this thesis represents the first in-depth analysis of a realistic large-scale aeronautical opportunistic network.

Повний текст джерелаDans la première partie, nous proposons un système permettant d'établir des communications interactives non-observables, c'est-à-dire telles qu'un observateur ne puisse pas déterminer vers quelle(s) destination(s) sont établies ces communications, ni même, en fait, être certain qu'il y a bien de vraies communications!
Ce système innove par le niveau de protection qu'il vise, puisque même un observateur très puissant ne devrait pas être à même de la contourner.
Cette protection se base sur l'Onion-Routing et le complète avec des méthodes sophistiquées destinées à déjouer l'analyse de trafic.
Dans la seconde partie, nous nous intéressons plus particulièrement au protocole DNS.
Bien qu'il soit possible de le protéger avec notre proposition de la partie précédente, cela dégrade ses performances (en termes de latence), ce qui à son tour a un impact sur celles des protocoles qui utilisent DNS.
Dans cette partie, nous proposons une solution spécifique à DNS, qui fournit à la fois un bon niveau de protection et de meilleures performances.
Ces deux systèmes peuvent bien sûr se combiner, mais aussi être utilisés comme des briques séparées, avec d'autre mécanismes de protection de la vie privée.

The Naval Undersea Warfare Center, Division Newport (NUWCDIVNPT), Code 382 has been assigned as the program manager for a T&E version of the 21CLP system. The 21CLP vision is a common instrumentation function that links, in real-time, live land, air and maritime entities together with a virtual battlespace in any location where forces are deployed or being trained, weapons systems are being tested and evaluated, and ultimately where missions are being conducted. This vision will be realized with an embedded, mobile, distributed, untethered system that requires little or no site preparation.
