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.

Wireless technology has gained great attention from both academia and industry in the past decades. It is believed to be the essential part to achieve the ultimate goal of communications: communication happens whenever, wherever, and to whomever. With the proliferation of different wireless technologies and their vast deployment, we will soon enter the age of ubiquitous computing. Compared to its wireline counterpart, wireless network faces more technical challenges. The wireless channel is less reliable and more variable than fibers and cables. Wireless devices are usually mobile and energy-constraint. Wireless transceiver has limited coverage area. All these characteristics make the resource allocation and algorithm design in wireless networks challenging tasks. This dissertation investigates both issues in different types of next-generation wireless networks. This dissertation first explores the problem of providing a traffic-oblivious routing and scheduling for wireless mesh networks. We present an optimization model which generates a static routing and scheduling policy with worst-case performance guarantees under a range of traffic conditions. Packet-level simulations demonstrate good average performance for the generated routing and scheduling in addition to its worse-case guarantees. Next, we investigate the problem of identifying the maximum capacity of multi-channel multi-radio wireless networks, given the number of available channels. We provide an Integer Linear Program (ILP) framework to compute the maximum capacity. We also discuss how to extend the framework to consider heterogeneous network. Then the framework will output the minimum number of radios necessary for each node to fully utilize the available channels, which can be used to identify the bottleneck in the topology, and also indicates the "goodness" of the topology. We also study the integration gain of heterogenous WiFi and WiMAX networks. We propose a generic framework to identify the integration gain, the gain comes from better utilization of resources rather than the addition of resources. For the performance objective, we focus on the max-min throughput fairness, and also briefly cover the proportional fairness. We propose approximation algorithms to achieve different objectives and compute the integration gain based on the framework. The proposed framework can be used to evaluate the potential benefit of combining different heterogeneous wireless networks. The approximation algorithms can be directly used to perform intelligent user association in the integrated network. Last, we study the unique characteristics of cognitive radio networks. Based on our observations, we propose distributed algorithms to perform channel allocation among secondary users. We consider both throughput and fairness, and study their tradeoff. This dissertation makes important contributions by introducing novel models, algorithms and architectures that will help improve the network analysis, planning, and deployment of next-generation wireless networks.

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.

This book surveys state-of-the-art optimization modeling for design, analysis, and management of wireless networks, such as cellular and wireless local area networks (LANs), and the services they deliver. The past two decades have seen a tremendous growth in the deployment and use of wireless networks. The current-generation wireless systems can provide mobile users with high-speed data services at rates substantially higher than those of the previous generation. As a result, the demand for mobile information services with high reliability, fast response times, and ubiquitous connectivity continues to increase rapidly. The optimization of system performance has become critically important both in terms of practical utility and commercial viability, and presents a rich area for research. In the editors' previous work on traditional wired networks, we have observed that designing low cost, survivable telecommunication networks involves extremely complicated processes. Commercial products available to help with this task typically have been based on simulation and/or proprietary heuristics. As demonstrated in this book, however, mathematical programming deserves a prominent place in the designer's toolkit. Convenient modeling languages and powerful optimization solvers have greatly facilitated the implementation of mathematical programming theory into the practice of commercial network design. These points are equally relevant and applicable in today’s world of wireless network technology and design. But there are new issues as well: many wireless network design decisions, such as routing and facility/element location, must be dealt with in innovative ways that are unique and distinct from wired (fiber optic) networks. The book specifically treats the recent research and the use of modeling languages and network optimization techniques that are playing particularly important and distinctive roles in the wireless domain.
