During past years many people have thought much about what a next generation network environment would look like and have proposed diverse ideas. Significant steps have already been made towards merging the many and often very different visions of such an environment into a more coherent picture in the first place, and then towards proposing the mechanisms, protocols, and technologies which would make possible its real-life rolling and eventually adoption. It was like putting together a puzzle with a secret picture whose overall aspect no one knows, but everybody can imagine. A puzzle at whose completion many people with potential different visions of the overall image are working together, revealing different areas of that picture at various moments in time. A puzzle whose secret picture keeps changing, evolving during the work of putting the puzzle together, often influenced by the work of the people in charge of finishing the puzzle themselves. A puzzle whose secret image is not only a 2D representation required for the communication between different entities, but a 3D structure based on the classic layered network architecture enhanced with novel contributions. In this context almost everybody agrees that the effort required to put this puzzle together is large and complex and there should be an expectation of many more years of hard and highly innovative work to be put towards the puzzle completion in order to fully develop the next generation network architecture and its underlying mechanisms.

In this concentrated effort imaginative thinking plays an important role, and identifying various scenarios and trying to find solutions for them have helped fuel the progress. Imagine a user leaving their house for work in the morning, journey in which they have to drive then take a public means of transport and finally walk to reach the city centre’s workplace. During commuting they may want to be directed via certain place (e.g. school or petrol station) following the best route, while also getting access to the latest news, listening to music and/or being informed about the most pressing work-related aspects of the day. At work regardless of the building or office the user is located in, there should be continuous communication and access to relevant applications in order to make work efficient. On the journey back home, avoiding high traffic while getting past certain landmarks (e.g. school, shopping centre), while also connecting with family and friends, performing other pending tasks and accessing infotainment are highly relevant. At home family routine may require availing from additional communication-related applications from various devices be them for talking to distant relatives or planning the day ahead or solving some other pressing problems.

In short in order to enable and support such a mobile dynamic lifestyle which is common to most of us, at least three major aspects need to be taken care of: devices, communication infrastructure, and services. Most users have access to complex computational devices be they desktops, laptops or simple mobile devices. With the advances in technology, computing devices such as smartphones, iPhones, and netbooks, have become more affordable, easy to use, and powerful, while enabling mobility to users while also making sure there is network connectivity. Network connectivity is possible via wired and wireless infrastructures. There are many Internet Service Providers which provide excellent wired connectivity to residential and business users alike. For local network access and service support wireless technologies such as WLAN (wireless local area network) and WPAN (wireless personal area network), can be employed. Additionally full wireless connectivity is supported via different radio access technologies, offered by different operators. These operators can provide connectivity by making use of different technologies such as: GSM (Global System for Mobile Communications), EDGE (Enhanced Data Rates for GSM Evolution), UMTS (Universal Mobile Telecommunications System), HSPA (High Speed Packet Access), LTE (Long Term Evolution), WiMAX (Worldwide Interoperability for Microwave Access), etc. One operator can cover different regions with different technologies.

Most of the effort put in enabling networked communications and providing the user with complex devices is done in order to support an increasingly extensive set of service types. Starting with the classic email and Web browsing services with basic best-effort transport requirements, continuing with online shopping and online banking which have additional requirements which include security and finishing with multimedia streaming, voice-over-IP (VoIP), mobile TV, and high definition television (HDTV) applications which put significant pressure on all components of the communication chain in terms of data amount and continuity-related demands is just an ever evolving set of services, which are increasingly hungry in terms of resources for content production, storage, delivery, processing and display. This continuous evolution is mainly triggered and fuelled by the users who are more and more interested in mobility, rich media content, novel services (e.g. social networking), etc.

In this context, there is a continuous race between the service, device and network researchers in order to propose solutions to the latest problems as response to users desire to access more complex content, in a higher quantity and in more difficult conditions. No single solution will solve all the problems the way no single device, no single service and no single network technology will be able to cope with the amount, type and requirements of data exchange. Multiple devices, multiple services and multiple co-existing access technologies, many of them in the radio space, will be fundamental for the next generation network communication in order to handle the volume and diversity of user application demands at high the quality levels expected by the users. Therefore the overall aim is to keep the user “always best connected” anywhere and anytime in this multi-technology multi-application multi-terminal multi-user environment.

This book will cover important aspects of the emerging technologies in the heterogeneous next generation network environment with focus on wireless communications and their quality. It presents network selection mechanisms, handover solutions and adaptive techniques. It identifies the research issues and challenges and presents a survey of the proposed solutions in the literature.

The manuscript is structured in two parts. The first part, on Architectures, describes the current wireless multi-access environment which leads towards the next generation of wireless networks. It includes important chapters written by researchers from prestigious laboratories from Australia, China, Mexico, Portugal, Greece, Germany, United Kingdom, and India which present the current state of the art in wireless communications including mobility challenges, management, security, ensuring always best experience, multimedia content distribution, etc. The second part entitled QoS Provisioning Solutions presents various solutions proposed by world known researchers in different areas of wireless communications. It includes research results in the area of ad-hoc networking, wireless sensor networking, cognitive and fibre networking, wireless mesh networking, etc.

The prospective audience of this book is mainly undergraduate students, postgraduate students, and researchers who are interested in learning more about the latest developments in the area of mobile and wireless communications. It also targets industry professionals who are working or are interested in this area, providing them with a reference of the latest efforts which bring the research further by addressing some of the shortcomings of the existing solutions.
