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.

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.

This work deals with the end-to-end QoS aware path computation problem under three separate parts: a distributed inter-domain scheme, a joint inter- layer/inter-domain path computation scheme and traffic engineering, and an inter-layer path computation algorithm for GMPLS networks. It first presents a distributed pre-reservation based procedure for inter-domain path computation of LSPs within a PCE based architecture. This allows the computation of optimal inter-domain paths with efficient setup times. It then extends this solution by considering the joint inter-layer/inter-domain problem for a complete view and global optimization. Finally it presents a novel mathematical program specific to GMPLS multi-layer path computation that solves the problem of nesting and un-nesting LSPs from one switching region to another.

The book describes protocols, architectures, standards mobility and performance for next generation wireless system.
