The service integration of different wireless access technologies is envisioned as a viable approach to accommodate the expected increase in the demand on wireless resources. This vision originates a new networking paradigm that introduces a new vertical mobility dimension, which significantly magnifies the mobility impact on the system performance and creates new challenging design issues that necessitate adopting novel innovative approaches to handle the inherent system heterogeneity.Clearly, vertical mobility is completely dismissed in the current mobility models that are primarily developed for homogeneous cellular systems. Hence, the development of new mobility models that consider vertical mobility in heterogeneous systems evolves as a crucial requirement for proper system design and performance evaluation. These models should satisfy general mobility modeling requirements such as flexibility and analytical tractability. More importantly, they should accommodate the correlation between the mobile terminal (MT) cell residence time (CRT) and the durations spent by the MT under the umbrellas of different technological coverage cocktails. In this dissertation, we developed a novel CRT mobility modeling framework that realizes the aforementioned modeling requirements. This framework is used to develop mobility models for two-tier and n-tier heterogeneous systems. Based on these models, we developed generic performance evaluation frameworks to estimate several salient performance metrics. Additionally, we employed the developed mobility modeling and performance evaluation frameworks to study several interesting network planning and dimensioning problems.In a complementary research direction, we studied vertical mobility management in heterogeneous systems. The asymmetric nature of vertical mobility is a novel design challenge that invalidates the traditional handoff decision mechanisms, which are based on comparing the signal strength from different base Stations of the same network. Hence, the vertical handoff decision should adopt novel mechanisms that consider a predetermined set of user preferences and network design goals. Consequently, we developed a novel flexible vertical handoff approach that, can adapt to different operating parameters such as, user mobility, required handoff delay, and different application requirements.

LTE- A and Next Generation Wireless Networks: Channel Modeling and Performance describes recent advances in propagation and channel modeling necessary for simulating next generation wireless systems. Due to the radio spectrum scarcity, two fundamental changes are anticipated compared to the current status. Firstly, the strict reservation of a specific band for a unique standard could evolve toward a priority policy allowing the co-existence of secondary users in a band allocated to a primary system. Secondly, a huge increase of the number of cells is expected by combining outdoor base stations with smaller cells such as pico/femto cells and relays. This evolution is accompanied with the emergence of cognitive radio that becomes a reality in terminals together with the development of self-organization capabilities and distributed cooperative behaviors. The book is divided into three parts: Part I addresses the fundamentals (e.g. technologies, channel modeling principles etc.) Part II addresses propagation and modeling discussing topics such as indoor propagation, outdoor propagation, etc. Part III explores system performance and applications (e.g. MIMO Over-the-air testing, electromagnetic safety, etc).

The convergence of wireless communication and the Internet is one of the strongest emerging markets in the telecommunications industry. This book consists of a compilation of papers on key issues related to 3G and 4G wireless communications and wireless access to next generation Internet (NGI). Included in Multiaccess, Mobility and Teletraffic for Wireless Communications: Volume 5 are new results on space-time access schemes that can dramatically increase the achievable bit rates of wireless systems, perhaps approaching bandwidth efficiencies in the order of 10 bits/s/Hz. The book also considers broadband wireless access to NGI. Effective management of radio resources in wireless systems is necessary for high spectral efficiency and to support mobility. This book treats issues relating to handoff and channel assignment in cellular frequency reuse systems. In order to achieve quality of service (QoS) expectations in a dynamically changing wireless environment, effective error and QoS control protocols are needed. To guarantee fairness in the access to resources, medium access control (MAC) protocols are needed. Optimization of network resources traffic and mobility models are also needed, along with effective call admission control strategies. All of these topics are covered herein. Finally, this book considers future 3G and 4G wireless systems and highlights the critical challenges that must be overcome to make these systems a commercial reality. Multiaccess, Mobility and Teletraffic for Wireless Communications: Volume 5 is an important book for researchers, students and professionals working in the area of wireless communications and mobile computing.

This book is an organized and edited work of enabling technologies for the applications and services needed for future wireless networks. Its focus is the defining architectures, services and applications, with coverage of all layers, i.e., from the physical layer to the information handling layers of the network. The new wireless network architectures are geared specifically for enabling mobility and location-enhanced applications. Presented first are tutorials on new network architectures, including a discussion of "infostations", the role of satellites in broadband wireless access, and the "infocity" concept. The next three chapters present material that describes the state-of-the-art in wireless geolocation systems (including "assisted GPS"), alternatives for wireless geolocation, and empirical data on wireless geolocation capabilities. The first of the last two chapters demonstrates the use of location information in next generation wireless networks, with coverage of real-time geolocation measurements in mobile connectivity. The final chapter portrays the creation of a "killer application" in wireless networks. Leading researchers in the field have contributed to this volume. Next Generation Wireless Networks is essential reading for engineers, researchers, application design specialists, and product managers in the field of wireless network architectures and wireless geolocation.

The success of first and second generation wireless systems has paved the way for further research opportunities towards the next generation systems. The two standards GSM and IS-95 based on TDMA and CDMA respectively, have deeply influenced our system-level understanding, bringing new perspectives on the problems associated with wireless networks and potential for innovations. This volume presents the proceedings of the second workshop on multiaccess, mobility and teletraffic for personal communications held in May 1996 in Paris, France where some important subjects on the next generation systems have been treated. These include topics dealing with information theoretic aspects, channel modeling, diversity, interference control, resource allocation, power control, packet multi-access, stochastic modeling of mobility and traffic, and wireless network control. The selected topics in this workshop and their presented set of solutions reflect the richness of the problems in wireless communications. Indeed, development of theoretical frameworks with considerable attention to the peculiar environment of wireless communications has been the prime objective of this workshop. To elaborate, consider the problem of multi-access methods which remains a challenge for researchers. A complete evaluation of an access scheme must consider different aspects such as propagation, interference, mobility and traffic modeling. Some common bases, paradigms and models are needed. For example, today, we do not have a common archetype like the A WGN channel as in classical statistical communication. Clearly, there is a need for justified assumptions and models.
