Communication systems are now ubiquitous and making them more intelligent remains very challenging.  The IFIP International Conference on Intelligence in Communication Systems is an effort to bring together researchers and practitioners who represent the latest developments in this area.  This volume contains selected papers from the conference in the following focus areas: ad hoc networks / hybrid networks / WLAN; security, privacy and consumer protection; adaptive architectures and protocols; flexible QoS and QoS management; flexible service specification, validation, searching and querying; service composition and Web services; personal, terminal and node mobility; programmable and active networks.

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 LTEIntroduces a mechanism that provides service continuity to end-users in self-organizing IP Multimedia Subsystem environmentsConsiders 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.

This timely Handbook provides a conceptual discussion and a wide empirical presentation of new disruptive forms of innovation producing appropriate technologies, addressing the needs of low-income populations, and providing alternative solutions for sustainable development. The Handbook of Innovation & Appropriate Technologies for International Development expertly analyses and compares contributions of appropriate technologies in developing, emerging and industrialized economies, including China and India, and their global development impacts. Additionally, it covers the transversal role of new international communication technologies, open access, digital tools as well as entrepreneurship and innovation from within emerging economies and in industrialized nations. Using empirical analyses of cases and experiences in manufacturing sectors and services, it covers both the formal and informal economy, and provides an insightful focus on differences and similarities across borders and sectors. NGO and private sector practitioners, public sector officers as well as academics specialized in development economics, entrepreneurship and engineering or management studies will find this Handbook to be illuminating and very informative. Science and technology producers and entrepreneurs will appreciate the global look into more sustainable development as related to appropriate technologies, and how they can be used across all economic backgrounds.

Over the last decade researchers and practitioners have developed a wide range of knowledge related to e-learning. This book provides state-of-the-art e-learning networked environments and architectures carried out over the last few years from a knowledge management perspective.The book is organized into four parts: After an introductory chapter which attempts to characterize the e-learning environments, Part I exposes the problems of building knowledge scenarios followed by Part II which analyzes the process of building knowledge environments. Part III summarizes the principles, methods and issues related to the design of knowledge networks and finally Part IV addresses the problem of retrieving resources and knowledge from networked environments.Presenting a wide-ranging survey of methods and applications from contributors from around the world, this book will be a valuable resource for researchers, practitioners and graduates.

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).

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.

Mobile Agents areat the crossroadsof twomore ancient concepts: agentand mobility. Theconceptofagentappearedinthe?eldofarti?cialintelligence(AI) inthelate1970sandisratherfuzzy,leadingtomanyde?nitions. Anagentis usually de?ned as a software servant that either relieves the user of routine, burdensome tasks such as appointment scheduling and e-mail disposition, or sortstheinformationthatisrelevanttotheuser'scurrentinterestsandneeds. This de?nition has made "agent " a buzzword within both the academic and industrialworlds.
