Les réseaux mobiles ad-hoc sont créés par un ensemble de terminaux sans fil qui communiquent entre eux sans utilisation de quelconque infrastructure existante. Le multicast est une manière efficace pour supporter beaucoup de ces applications qui demandent des communications multipoint. Les défis supplémentaires tels que le changement fréquent de topologie et les ressources limitées sont à relever dans la conception de protocole multicast.Dans cette thèse, nous examinons d'abord les techniques qui sont employées par des protocoles courants. Ensuite, nous présentons notre proposition: MRDC, pour fournir un routage de multicast de "best effort" qui donne une optimisation entre les surcharges liées au routage et les surcharges de transmission mais également entre le taux de succès de la livraison et les surcharges en regardant des exigences des applications et les conditions du réseau. Pour les applications qui exigent la livraison fiable de paquets, nous proposons un protocole fiable de multicast, ARMPIS, qui active des noeuds intermédiaires pour aider les retransmissions. Tous ces travaux ont pour optimiser le taux de livraison de paquets pour répondre aux exigences des applications avec la bonne utilisation des ressources du réseau et notamment la bande de passante.Cette thèse inclut également notre experience de la construction d'un banc de test de réseau ad-hoc. Ce banc de test est développé par l'implementation de d'un protocole de routage d'unicast et de MRDC de sorte qu'il puisse supporter des communications point-à-point et aussi des communications multipoint. Il nous permettra d'analyser la performance de protocole et d'étudier de nouvelles applications.

In 1967, Canada celebrated the 100th anniversary of its founding with a spectacular party, and the whole world was invited. Montreal's Expo 67 was the first world's fair held in Canada, and it was a huge success, attracting over 50 million visitors. The 1,000-acre site was built on two man-made islands in the St. Lawrence River and incorporated 90 futuristic pavilions created by some of the world's greatest architects and designers. Over 60 countries were represented, along with many private, corporate and thematic pavilions, all brought together under the theme "Man and his World." With performers and entertainers of all varieties, restaurants, cultural attractions, exhibitions and a world-class amusement park, Expo 67 was literally the party of the century, exceeding all expectations.

A concise introduction to IMT-Advanced Systems, including LTE-Advanced and WiMAX There exists a strong demand for fully extending emerging Internet services, including collaborative applications and social networking, to the mobile and wireless domain. Delivering such services can be possible only through realizing broadband in the wireless. Two candidate technologies are currently competing in fulfilling the requirements for wireless broadband networks, WiMAX and LTE. At the moment, LTE and its future evolution LTE-Advanced are already gaining ground in terms of vendor and operator support. Whilst both technologies share certain attributes (utilizing Orthogonal Frequency Division Multiple Access (OFDMA) in downlink, accommodating smart antennas and full support for IP-switching, for example), they differ in others (including uplink technology, scheduling, frame structure and mobility support). Beyond technological merits, factors such as deployment readiness, ecosystem maturity and migration feasibility come to light when comparing the aptitude of the two technologies. LTE, LTE-Advanced and WiMAX: Towards IMT-Advanced Networks provides a concise, no-nonsense introduction to the two technologies, covering both interface and networking considerations. More critically, the book gives a multi-faceted comparison, carefully analyzing and distinguishing the characteristics of each technology and spanning both technical and economic merits. A “big picture” understanding of the market strategies and forecasts is also offered. Discusses and critically evaluates LTE, LTE-Advanced and WiMAX (Legacy and Advanced) Gives an overview of the principles and advances of each enabling technology Offers a feature-by-feature comparison between the candidate technologies Includes information which appeals to both industry practitioners and academics Provides an up-to-date report on market and industry status

Principles of Mobile Communication provides an authoritative treatment of the fundamentals of mobile communications, one of the fastest growing areas of the modern telecommunications industry. The book stresses the fundamentals of mobile communications engineering that are important for the design of any mobile system. Less emphasis is placed on the description of existing and proposed wireless standards. This focus on fundamental issues should be of benefit not only to students taking formal instruction but also to practising engineers who are likely to already have a detailed familiarity with the standards and are seeking to deepen their knowledge of this important field. The book stresses mathematical modeling and analysis, rather than providing a qualitative overview. It has been specifically developed as a textbook for graduate level instruction and a reference book for practising engineers and those seeking to pursue research in the area. The book contains sufficient background material for the novice, yet enough advanced material for a sequence of graduate level courses. Principles of Mobile Communication treats a variety of contemporary issues, many of which have been treated before only in the journals. Some material in the book has never appeared before in the literature. The book provides an up-to-date treatment of the subject area at a level of detail that is not available in other books. Also, the book is unique in that the whole range of topics covered is not presently available in any other book. Throughout the book, detailed derivations are provided and extensive references to the literature are made. This is of value to the reader wishing to gain detailed knowledge of a particular topic.

This revised edition of Communication Systems from GSM to LTE: An Introduction to Mobile Networks and Mobile Broadband Second Edition (Wiley 2010) contains not only a technical description of the different wireless systems available today, but also explains the rationale behind the different mechanisms and implementations; not only the ‘how’ but also the ‘why’. In this way, the advantages and also limitations of each technology become apparent. Offering a solid introduction to major global wireless standards and comparisons of the different wireless technologies and their applications, this edition has been updated to provide the latest directions and activities in 3GPP standardization up to Release 12, and importantly includes a new chapter on Voice over LTE (VoLTE). There are new sections on Building Blocks of a Voice Centric Device, Building Blocks of a Smart Phone, Fast Dormancy, IMS and High-Speed Downlink Packet Access, and Wi-Fi-Protected Setup. Other sections have been considerably updated in places reflecting the current state of the technology. • Describes the different systems based on the standards, their practical implementation and design assumptions, and the performance and capacity of each system in practice is analyzed and explained • Questions at the end of each chapter and answers on the accompanying website make this book ideal for self-study or as course material
