The beginning of the twenty-first century is characterized by global markets, and the mobility of people is becoming an important fact of life. Consequently, the mobile user is demanding appropriate technical solutions to make use of customized information and communication services. In this context the notion of next-generation networks (NGNs), which are driven by the convergence of the entertainment sector, the mobile Internet, and fixed/mobile telecommunications, is emerging. Such NGNs are aggregating a variety of different access networks and supporting the seamless connection of an open set of end-user devices, and due to the adoption of an all-IP network paradigm they enable a much better integration of voice and data services. Coincidently the buzzword 'fixed mobile convergence' (FMC) describes the current trend towards providing common services across fixed and mobile networks resulting in the medium term in the full integration of fixed and mobile telecommunication networks. The adoption of appropriate middleware technologies and the provision of - called service delivery platforms driven by the ongoing innovation in the field of information technologies provides today the technical foundation for supporting terminal, personal and service mobility and thus the implementation of real seamless information and communication services. Furthermore, users are nowadays looking, in light of an omnipresent service environment, for a much higher degree of customization and context awareness in the services they use. The papers in this volume look at these enabling mobility-aware technologies and their use for implementing mobility-aware and context-aware applications.

AdHoc Networks are wireless, self-organizing systems formed by co-operating nodes, within communication range of each other which form temporary n- works. Their topology is dynamic, decentralized, and ever-changing, and the nodes may move around arbitrarily. The last few years have witnessed a wealth ofresearchideasonAdHocnetworkswhicharemovingrapidlyintoimplemented standards. Mobile computing, particularly wireless-enabled mobile computing, covers a large area of applications in mobile computing environments, networking, c- municationdevicesandsystems.Thisconferenceexposesexperimentalaswellas theoretical research in adhoc, mobile and wireless networks. The range of topics covered includes management of power consumption, architectures and pro- cols, quality of service, and security. The aim of the conference was to provide a unique opportunity for researchers and students in industry and academia to participate at an annual forum and share their research results and experiences. This conference followed the ?rst successful conference (held at the Fields - stituteinTorontoduringSeptember20-21oflastyear),andwasheldattheH- iday Inn, Midtown in Montreal during October 8-10, 2003. It was co-sponsored by the Mobile Computing and Networking Research Laboratory (LARIM) of the ' Ecole Polytechnique de Montr' eal, theSchool of Computer Science (SCS) of C- leton University, MITACS (Mathematics of Information Technology and C- plex Systems), and the Association for Computing Machinery (ACM).

This book constitutes the refereed proceedings of the Third International Workshop on Mobile Agents for Telecommunication Applications, MATA 2001, held in Montreal, Canada in August 2001. The 26 revised full papers presented were carefully reviewed and selected for inclusion in the volume. Among the topics addressed are network management, mobile applications, nomadic computing, feature interaction, Internet applications, QoS managment, policy-based management, interactive multimedia, tele-learning, and computer telephony integration.

Explore Twisted, the Python-based event-driven networking engine, and review several of its most popular application projects. It is written by community leaders who have contributed to many of the projects covered, and share their hard-won insights and experience. Expert Twisted starts with an introduction to event-driven programming, explaining it in the context of what makes Twisted unique. It shows how Twisted's design emphasizes testability as a solution to common challenges of reliability, debugging, and start-to-finish causality that are inherent in event-driven programming. It also explains asynchronous programming, and the importance of functions, deferreds, and coroutines. It then uses two popular applications, treq and klein, to demonstrate calling and writing Web APIs with Twisted. The second part of the book dives into Twisted projects, in each case explaining how the project fits into the Twisted ecosystem and what it does, and offers several examples to bring readers up to speed, with pointers to additional resources for more depth. Examples include using Twisted with Docker, as a WSGI container, for file sharing, and more. What You'll Learn Integrate Twisted and asyncio using adapters Automate software build, test, and release processes with Buildbot Create clients and servers with Autobahn Transfer files with Magic Wormhole Distribute cloud-based file storage with Tahoe LAFS Understand HTTP/2 with Python and Twisted Support for asynchronous tasks using Django Channels Who This Book Is For Readers should have some Python experience and understand the essentials of containers and protocols, but need not be familiar with Twisted or the associated projects covered in the book.

An authoritative collection of research papers and surveys, Emerging Wireless Networks: Concepts, Techniques, and Applications explores recent developments in next-generation wireless networks (NGWNs) and mobile broadband networks technologies, including 4G (LTE, WiMAX), 3G (UMTS, HSPA), WiFi, mobile ad hoc networks, mesh networks, and wireless sensor networks. Focusing on improving the performance of wireless networks and provisioning better quality of service and quality of experience for users, it reports on the standards of different emerging wireless networks, applications, and service frameworks.

The book begins by appraising the management challenges in emerging wireless networks. It examines the state-of-the-art in mobility management for IP-based mobile networks, at both the network and link layers. Proposing an integrated network architecture design for NGWNs including wireless local, metropolitan, and wide area networks it analyzes WLAN/3G network convergence and advanced mobility features based on the IP Multimedia Subsystem (IMS) architecture. It highlights the challenges and issues related to mobile virtual private networks, and also:

• Examines the emerging mobile broadband wireless standards such as IEEE 802.16 and LTE
• Introduces a mechanism that provides service continuity to end-users in self-organizing IP Multimedia Subsystem environments
• Considers the challenges, solutions, and services of vehicular communication networks
• Unveils a new transmission paradigm (network coding) to improve the performance of the transmission control protocol.

The book presents a novel distributed scheme based on the stochastic optimization formulation of the network selection problem for heterogeneous wireless networks by using cognitive radio networks concepts. Describing the issues and schemes for network selection and congestion avoidance in multi-access networks, it supplies you with a clear perspective of where the technology is headed and where future opportunities might be found for mobile broadband technologies.
