Book excerpt: Doctoral Thesis / Dissertation from the year 2011 in the subject Computer Science - Internet, New Technologies, Lille 1 University (Laboratoire d'Informatique Fondamentale de Lille), course: Security in Wireless Multi-hop Networks, language: English, abstract: While the rapid proliferation of mobile devices along with the tremendous growth of various applications using wireless multi-hop networks have significantly facilitate our human life, securing and ensuring high quality services of these networks are still a primary concern. In particular, anomalous protocol operation in wireless multi-hop networks has recently received considerable attention in the research community. These relevant security issues are fundamentally different from those of wireline networks due to the special characteristics of wireless multi-hop networks, such as the limited energy resources and the lack of centralized control. These issues are extremely hard to cope with due to the absence of trust relationships between the nodes. To enhance security in wireless multi-hop networks, this dissertation addresses both MAC and routing layers misbehaviors issues, with main focuses on thwarting black hole attack in proactive routing protocols like OLSR, and greedy behavior in IEEE 802.11 MAC protocol. Our contributions are briefly summarized as follows. As for black hole attack, we analyze two types of attack scenarios: one is launched at routing layer, and the other is cross layer. We then provide comprehensive analysis on the consequences of this attack and propose effective countermeasures. As for MAC layer misbehavior, we particularly study the adaptive greedy behavior in the context of Wireless Mesh Networks (WMNs) and propose FLSAC (Fuzzy Logic based scheme to Struggle against Adaptive Cheaters) to cope with it. A new characterization of the greedy behavior in Mobile Ad Hoc Networks (MANETs) is also introduced. Finally, we design a new backoff scheme to quickly detect the greedy nodes that do not comply with IEEE 802.11 MAC protocol, together with a reaction scheme that encourages the greedy nodes to become honest rather than punishing them.

Nous proposons ainsi une nouvelle Les réseaux sans fil à multi-sauts se communiquent par des liens hertziens par le relayage de paquets (les sauts). La très haute dynamique dans cet environnement force l'utilisation des approches d'auto-configuration, c'est-à-dire des approches où les paramètres des terminaux sont adaptés automatiquement face approche de partage d'informations d'auto-configuration et de cross-layer, basée sur le concept du plan de d'information, ainsi que deux algorithmes de auto-configuration qui les utilisent. Nous commençons la thèse avec l'architecture et l'évaluation du logiciel du plan d'information. Ensuite nous présentons et évaluons les deux algorithmes d'auto-configuration proposés. Le premier algorithme améliore le routage en prenant en compte la bande passante et la puissance de transmission des liens sans fil hertziens. Nous présentons un modèle mathématique pour ce problème comme support à notre proposition. Le deuxième algorithme utilise la théorie de contrôle et la logique floue pour adapter le mécanisme d'enquêtes d'une application pair à pair à la charge du réseau.

Download or read book Sustainable Wireless Sensor Networks written by Yen Kheng Tan and published by BoD – Books on Demand. This book was released on 2010-12-14 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless Sensor Networks came into prominence around the start of this millennium motivated by the omnipresent scenario of small-sized sensors with limited power deployed in large numbers over an area to monitor different phenomenon. The sole motivation of a large portion of research efforts has been to maximize the lifetime of the network, where network lifetime is typically measured from the instant of deployment to the point when one of the nodes has expended its limited power source and becomes in-operational - commonly referred as first node failure. Over the years, research has increasingly adopted ideas from wireless communications as well as embedded systems development in order to move this technology closer to realistic deployment scenarios. In such a rich research area as wireless sensor networks, it is difficult if not impossible to provide a comprehensive coverage of all relevant aspects. In this book, we hope to give the reader with a snapshot of some aspects of wireless sensor networks research that provides both a high level overview as well as detailed discussion on specific areas.

Available in PDF, EPUB and Kindle. Book excerpt: De nombreux protocoles, basés sur les contentions entre les receveurs, ont été proposés pour les réseaux de capteurs sans fil (WSNs). Ces protocoles ont besoin de capteurs connaissant la localisation géographique de tous ses nœuds voisins, afin d'optimiser la transmission vers la station centrale. La position des nœuds peut-être déterminée par un système de localisation, e.g., le système de positionnement global (GPS). Cependant, ce genre de système est difficilement adaptable en raison de son volume, son coût financier et sa consommation d'énergie. Par conséquent, un nouveau protocole inter-couche MAC/routage, basé sur l'indicateur de niveau du signal reçu (RSSI) est proposé pour les réseaux de capteurs multi-sauts. L'affaiblissement du signal le long du parcours (Path Loss), mesuré à partir de paquets balise (beacon packet) transmis par le collecteur, est utilisé par le protocole comme paramètre clé afin de sélectionner le nœud relais. Un nœud situé près du collecteur sera donc privilégié comme relais à cause de son niveau d'énergie résiduelle important. Pour réduire la consommation d'énergie, nous proposons une commande adaptative des cycles d'activité, pour la planification d'un candidat au relayage en mode sommeil, en fonction du nombre de voisins. Cette nouvelle planification permet une meilleure utilisation de l'énergie par paquet de données et une augmentation de la durée de vie du réseau lorsque la densité des nœuds augmente. Ce nouveau protocole, dédié à une seule station de collecte, est également étendu pour une configuration multi-stations utilisant la mesure de multiples affaiblissements de signaux. De plus, nous proposons de nouvelles solutions de routage de réseaux multi-stations : Minimum Path Loss (MPL) et 1-Hop Residual Energy Feedback (1HREF). Les performances du protocole et des solutions de routage proposées sont évaluées au moyen de simulations.

Download or read book Corpus written by Jean-Luc Nancy and published by Fordham Univ Press. This book was released on 2009-08-25 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: How have we thought “the body”? How can we think it anew? The body of mortal creatures, the body politic, the body of letters and of laws, the “mystical body of Christ”—all these (and others) are incorporated in the word Corpus, the title and topic of Jean-Luc Nancy’s masterwork. Corpus is a work of literary force at once phenomenological, sociological, theological, and philosophical in its multiple orientations and approaches. In thirty-six brief sections, Nancy offers us at once an encyclopedia and a polemical program—reviewing classical takes on the “corpus” from Plato, Aristotle, and Saint Paul to Descartes, Hegel, Husserl, and Freud, while demonstrating that the mutations (technological, biological, and political) of our own culture have given rise to the need for a new understanding of the body. He not only tells the story of this cultural change but also explores the promise and responsibilities that such a new understanding entails. The long-awaited English translation is a bold, bravura rendering. To the title essay are added five closely related recent pieces—including a commentary by Antonia Birnbaum—dedicated in large part to the legacy of the “mind-body problem” formulated by Descartes and the challenge it poses to rethinking the ancient problems of the corpus. The last and most poignant of these essays is “The Intruder,” Nancy’s philosophical meditation on his heart transplant. The book also serves as the opening move in Nancy’s larger project called “The deconstruction of Christianity.”

Download or read book Building Wireless Community Networks written by Rob Flickenger and published by "O'Reilly Media, Inc.". This book was released on 2003 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building Wireless Community Networks is about getting people online using wireless network technology. The 802.11b standard (also known as WiFi) makes it possible to network towns, schools, neighborhoods, small business, and almost any kind of organization. All that's required is a willingness to cooperate and share resources. The first edition of this book helped thousands of people engage in community networking activities. At the time, it was impossible to predict how quickly and thoroughly WiFi would penetrate the marketplace. Today, with WiFi-enabled computers almost as common as Ethernet, it makes even more sense to take the next step and network your community using nothing but freely available radio spectrum. This book has showed many people how to make their network available, even from the park bench, how to extend high-speed Internet access into the many areas not served by DSL and cable providers, and how to build working communities and a shared though intangible network. All that's required to create an access point for high-speed Internet connection is a gateway or base station. Once that is set up, any computer with a wireless card can log onto the network and share its resources. Rob Flickenger built such a network in northern California, and continues to participate in network-building efforts. His nuts-and-bolts guide covers: Selecting the appropriate equipment Finding antenna sites, and building and installing antennas Protecting your network from inappropriate access New network monitoring tools and techniques (new) Regulations affecting wireless deployment (new) IP network administration, including DNS and IP Tunneling (new) His expertise, as well as his sense of humor and enthusiasm for the topic, makes Building Wireless Community Networks a very useful and readable book for anyone interested in wireless connectivity.

Download or read book GeoSensor Networks written by Silvia Nittel and published by Springer. This book was released on 2008-08-15 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume serves as the post-conference proceedings for the Second GeoSensor Networks Conference that was held in Boston, Massachusetts in October 2006. The conference addressed issues related to the collection, management, processing, ana- sis, and delivery of real-time geospatial data using distributed geosensor networks. This represents an evolution of the traditional static and centralized geocomputational paradigm, to support the collection of both temporally and spatially high-resolution, up-to-date data over a broad geographic area, and to use sensor networks as actuators in geographic space. Sensors in these environments can be static or mobile, and can be used to passively collect information about the environment or, eventually, to actively influence it. The research challenges behind this novel paradigm extend the frontiers of tra- tional GIS research further into computer science, addressing issues like data stream processing, mobile computing, location-based services, temporal-spatial queries over geosensor networks, adaptable middleware, sensor data integration and mining, au- mated updating of geospatial databases, VR modeling, and computer vision. In order to address these topics, the GSN 2006 conference brought together leading experts in these fields, and provided a three-day forum to present papers and exchange ideas.
