Multi-access mobile devices and overlapping mobile and wireless network deployments have emerged as a reality in the converged telecommunications world. In heterogeneous wireless and mobile environment it is highly important to provide QoS support and seamless handovers between different radio access networks, something that is particularly needed for real-time services. Therefore, this book provides performance analysis of packet scheduling algorithms for cellular mobile networks and for WiMAX. Also, it provides QoS analysis of vertical handover for VoIP and video traffic in a heterogeneous wireless environment. Further, the book proposes improvements for vertical handover decision algorithms regarding the QoS provisioning in mobile and wireless heterogeneous networks, accompanied with numerical analysis and radio access technology selection algorithm. Finally, it gives important discussions and conclusions for improving the QoS in heterogeneous mobile and wireless networks. Hence, this book is useful for all professionals in mobile and wireless networking and to everyone else who is interested in this field of science.

Heterogeneous wireless networking, which is sometimes referred to as the fourth-generation (4G) wireless, is a new frontier in the future wireless communications technology and there has been a growing interest on this topic among researchers and engineers in both academia and industry. This book will include a set of research and survey articles featuring the recent advances in theory and applications of heterogeneous wireless networking technology for the next generation (e.g., fourth generation) wireless communications systems. With the rapid growth in the number of wireless applications, services and devices, using a single wireless technology such as a second generation (2G) and third generation (3G) wireless system would not be efficient to deliver high speed data rate and quality-of-service (QoS) support to mobile users in a seamless way. Fourth generation (4G) wireless systems are devised with the vision of heterogeneity in which a mobile user/device will be able to connect to multiple wireless networks (e.g., WLAN, cellular, WMAN) simultaneously. This book intends to provide a unified view on the state-of-the-art of protocols and architectures for heterogeneous wireless networking. The contributed articles will cover both the theoretical concepts and system-level implementation issues related to design, analysis, and optimization of architectures and protocols for heterogeneous wireless access networks.

In accordance with the latest research, this book presents several segments that describe the direction and techniques together with actual implementation of new methods for controlling and improving of the quality of services in future generation mobile networks. It gives review of the architectures of the future generations of networks, it performs analysis of network architectures in heterogeneous networks and the ways radio resource management is achieved in each of them. The main focus was given on the heterogeneous wireless networks, through which a new proposal is presented for their architecture of internetwork operation using the Internet model for interoperability between radio access technologies that participate in the construction of heterogeneous networks. The proposed new architecture in this book defines the unique ecosystem of inter-network operation between different RAT's that form next generation mobile networks. Furthermore, the book defines a new algorithm for selecting of access network in heterogeneous wireless environment by using algorithms from artificial intelligence. This proposal can be base for implementation of new 5G architecture.

This volume presents the proceedings of the 6th International ICST Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness and of the Third International ICST Workshop on Advanced Architectures and Algorithms for Internet DElivery and Applications. Both events were held in Las Palmas de Gran Canaria in November 2009. To each of these events is devoted a specific part of the volume. The first part is dedicated to the proceedings of ICST QShine 2009. The first four chapters deal with new issues concerning the quality of service in IP-based telephony and multimedia. A second set of four chapters addresses some important research problems in mul- hop wireless networks, with a special emphasis on the problems of routing. The following three papers deal with recent advances in the field of data mana- ment and area coverage in sensor networks, while a fourth set of chapters deals with mobility and context-aware services. The fifth set of chapters contains new works in the area of Internet delivery and switching systems. The following chapters of the QShine part of the volume are devoted to papers in the areas of resource management in wireless networks, overlay, P2P and SOA arc- tectures. Some works also deal with the optimization of quality of service and energy consumption in WLAN and sensor networks and on the design of a mobility support in mesh networks.

QShine 2004 looks at recent technological developments and challenging new problems in broadband high-speed networks, P2P networks, wireless and mobile networks, and Grid computing. The topics covered include voice and multi-media protocols, QoS routing, reliability and resource management, wired-wireless networks, and advanced routing techniques.

With the ubiquitous diffusion of the IoT, Cloud Computing, 5G and other evolved wireless technologies into our daily lives, the world will see the Internet of the future expand ever more quickly. Driving the progress of communications and connectivity are mobile and wireless technologies, including traditional WLANs technologies and low, ultra-power, short and long-range technologies. These technologies facilitate the communication among the growing number of connected devices, leading to the generation of huge volumes of data. Processing and analysis of such "big data" brings about many opportunities, as well as many challenges, such as those relating to efficient power consumptions, security, privacy, management, and quality of service. This book is about the technologies, opportunities and challenges that can drive and shape the networks of the future. Written by established international researchers and experts, Networks of the Future answers fundamental and pressing research challenges in the field, including architectural shifts, concepts, mitigation solutions and techniques, and key technologies in the areas of networking. The book starts with a discussion on Cognitive Radio (CR) technologies as promising solutions for improving spectrum utilization, and also highlights the advances in CR spectrum sensing techniques and resource management methods. The second part of the book presents the latest developments and research in the areas of 5G technologies and Software Defined Networks (SDN). Solutions to the most pressing challenges facing the adoption of 5G technologies are also covered, and the new paradigm known as Fog Computing is examined in the context of 5G networks. The focus next shifts to efficient solutions for future heterogeneous networks. It consists of a collection of chapters that discuss self-healing solutions, dealing with Network Virtualization, QoS in heterogeneous networks, and energy efficient techniques for Passive Optical Networks and Wireless Sensor Networks. Finally, the areas of IoT and Big Data are discussed, including the latest developments and future perspectives of Big Data and the IoT paradigms.
