The development and proliferation of wireless technologies has revolutionized communications. With the advent of the cellular phone, an untethered, mobile lifestyle has become both possible and prevalent. As a result, many users are coming to expect and demand ubiquitous connectivity for phone service, as well as Internet-related applications like e-mail and web browsing. Unfortunately, the existing cellular infrastructure is ill-suited for high-bandwidth, data-centric applications, and the traditional Internet provides inadequate support for highly mobile devices.

The third volume of the influential WWRF Book of Visions of research and trends in mobile communications has been fully updated. It includes three new chapters on flexible spectrum use, ultra-broadband convergent home-area networks, and the system concept. Visions from manufacturers, network operators, research institutes and academia from all over world are captured by the WWRF in one comprehensive single point of reference. Technologies for the Wireless Future, Volume 3 describes the expectations and requirements of a user in the ‘future wireless world’ between 2010 and 2017. This will enable readers to prioritise research topics based on the provision of cost-effective solutions. This book is ideal for researchers from both academia and industry, as well as engineers, managers, strategists, and regulators. WWRF has become highly influential on the future of wireless communication. You can see the evidence already, as many of the concepts described in the very first Book of Vision have been adopted in today’s wireless implementations. The organization brings together the long-range views of academia with the practical constraints and requirements of industry. This is a powerful combination. Mark Pecen, Vice President, Research In Motion Limited The WWRF Book of Vision series of books are an invaluable source of information for key thoughts and technology developments in wireless and mobile communication. The comprehensiveness and diversified nature of its research reports and results can prove to be a very useful tool in planning and developing the next generation network and services. Bill Huang, General Manager, China Mobile Research As mobile broadband becomes part of our daily lives, in the same way that mobile telephony has done, and helps us to support important issues such as health care, education and many other priorities, WWRF is again exploring the options for mobile and wireless systems in its' third edition of the Book of Visions. Earlier versions have helped to reach global consensus on research objectives, reduce investment risk and generate critical mass in research efforts. The third book of visions provides key insights into the international academic and commercial discussion on tomorrows' hot topics in mobile research!

Over the last few decades, we have been witnessing a tremendous evolution in mobile computing, wireless networking and hand-held devices. In the future communication networks, users are anticipated to become even more mobile demanding for ubiquitous connectivity to different applications which will be preferably aware of their context. Admittedly, location information as part of their context is of paramount importance from both application and network perspectives. From application or user point of view, service provision can upgrade if adaptation to the user's context is enabled. From network point of view, functionalities such as routing, handoff management, resource allocation and others can also benefit if user's location can be tracked or even predicted. Within this context, we focus our attention on indoor localization and handoff prediction which are indispensable components towards the ultimate success of the envisioned pervasive communication era. While outdoor positioning systems have already proven their potential in a wide range of commercial applications, the path towards a successful indoor location system is recognized to be much more difficult, mainly due to the harsh indoor characteristics and requirement for higher accuracy. Similarly, handoff management in the future heterogeneous wireless networks is much more challenging than in traditional homogeneous networks. Handoff schemes must be seamless for meeting strict Quality of Service (QoS) requirements of the future applications and functional despite the diversity of operation features of the different technologies. In addition, handoff decisions should be flexible enough to accommodate user preferences from a wide range of criteria offered by all technologies. The main objective of this thesis is to devise accurate, time and power efficient location and handoff management systems in order to satisfy better context-aware and mobile applications. For indoor localization, the potential of Wireless Local Area Network (WLAN) and Radio Frequency Identification (RFID) technologies as standalone location sensing technologies are first studied by testing several algorithms and metrics in a real experimental testbed or by extensive simulations, while their shortcomings are also identified. Their integration in a common architecture is then proposed in order to combine their key benefits and overcome their limitations. The performance superiority of the synergetic system over the stand alone counterparts is validated via extensive analysis. Regarding the handoff management task, we pinpoint that context awareness can also enhance the network functionality. Consequently, two such schemes which utilize information obtained from localization systems are proposed. The first scheme relies on a RFID tag deployment, alike our RFID positioning architecture, and by following the WLAN scene analysis positioning concept, predicts the next network layer location, i.e. the next point of attachment to the network. The second scheme relies on an integrated RFID and Wireless Sensor/Actuator Network (WSAN) deployment for tracking the users' physical location and subsequently for predicting next their handoff point at both link and network layers. Being independent of the underlying principle wireless access technology, both schemes can be easily implemented in heterogeneous networks. Performance evaluation results demonstrate the advantages of the proposed schemes over the standard protocols regarding prediction accuracy, time latency and energy savings.
Designers of wireless networks face a problem which is multidimensional in nature, where issues of multiaccess, radio propagation, antennas, mobility and teletraffic all need to be understood and simultaneously addressed in order to create a properly functioning system. This book does not merely concentrate on one of these issues but takes a broader view, and presents a mix of papers addressing systems and networking issues. Multiaccess, Mobility and Teletraffic: Advances in Wireless Networks addresses fundamental theoretical issues about future wireless networks, such as capacity improvements theoretically attainable from spread spectrum systems, and practical concerns associated with current networks such as signalling, implementation of GSM and CDMA networks, and implementation of packet data services over wireless networks. As well as the papers looking at specific technologies, this book contains a number of papers discussing more generic problems in mobile networks, such as issues associated with handoff, resource management, frequency reuse, mobility, signalling and wireless packet networks. Multiaccess, Mobility and Teletraffic: Advances in Wireless Networks covers a broad range of issues associated with wireless networks and provides a very interesting snapshot of the current state-of-the-art. It will be of interest to all researchers and practitioners working in the field of wireless communications and networks.
