With the explosive increase in the number of mobile devices and applications, it is anticipated that wireless traffic will increase exponentially in the coming years. Moreover, future wireless networks all carry a wide variety of flows, such as video streaming, online gaming, and VoIP, which have various quality of service (QoS) requirements. Therefore, a new mechanism that can provide satisfactory performance to the complete variety of all kinds of flows, in a coherent and unified framework, is needed. In this book, we introduce a framework for real-time wireless networks. This consists of a model that jointly addresses several practical concerns for real-time wireless networks, including per-packet delay bounds, throughput requirements, and heterogeneity of wireless channels. We detail how this framework can be employed to address a wide range of problems, including admission control, packet scheduling, and utility maximization. Table of Contents: Preface / Introduction / A Study of the Base Case / Admission Control / Scheduling Policies / Utility Maximization without Rate Adaptation / Utility Maximization with Rate Adaptation / Systems with Both Real-Time Flows and Non-Real-Time Flows / Broadcasting and Network Coding / Bibliography / Authors' Biographies

This Synthesis Lecture presents a discussion of Quality of Service (QoS) in wireless networks over unlicensed spectrum. The topic is presented from the point of view of protocols for wireless networks (e.g., 802.11) rather than the physical layer point of view usually discussed for cellular networks in the licensed wireless spectrum. A large number of mobile multimedia wireless applications are being deployed over WiFi (IEEE 802.11) and Bluetooth wireless networks and the number will increase in the future as more phones, tablets, and laptops are equipped with these unlicensed spectrum wireless interfaces. Achieving QoS objectives in wireless networks is challenging due to limited wireless resources, wireless nodes interference, wireless shared media, node mobility, and diverse topologies. The author presents the QoS problem as (1) an optimization problem with different constraints coming from the interference, mobility, and wireless resource constraints and (2) an algorithmic problem with fundamental algorithmic functions within wireless resource management and protocols.

This dissertation recommends system engineering designs that implement the latest technologies in OFDMA cellular and femtocellular networks, specifically in the area of resource allocation and interference coordination. These recommended designs guarantee good user experience for time-sensitive applications such as streaming video. While throughput is often the metric used to benchmark a system, field performance requires the system also guarantees a maximum service latency to satisfy users. This dissertation provides both intuitive and low-overhead schemes that are robust and practical for implementation. The novelty of this work is the application of stochastic control techniques that guarantee the Quality of Service (QoS) through proper buffer management. Guarantee of a non-empty user buffer for streaming applications prevents service interruption. The thesis considers both centralized and distributed topologies that result from either a single base-station serving many users, or many femtocell base-stations each serving a single user, respectively. This dissertation provides insight and solutions to the following question: Under the constraints of buffer management, how does a system engineer determine the transmission scheme, resource allocation algorithms, transmitter coordination, user feedback, and achievable QoS guarantees that maximize efficiency. A combination of theory, heuristics motivated in theory, and numerical simulations will justify the presented methods.

The emerging trends in computing have increasingly had a network-centric focus. Networked services offered through cloud computing paradigms have replaced applications that would traditionally run on local machines. In addition, the growing usage of applications such as social networking and platforms such as smartphones has resulted in greater need for ubiquitous network access. The consequent heightened demand for networked computing warrants efficient utilization of the limited network resources and more intelligent resource control algorithms, with a focus on providing an enhanced user experience. This thesis examines quality-of-service aware resource control for both wireless and wired networks. The first part of the thesis focuses on smartphones, which have become the de-facto mobile computing platform. A smartphone typically has access to multiple types of wireless networks, such as cellular networks and WiFi. Moreover, the functionality of smartphones can be expanded by installing applications. These two core characteristics of smartphones also reveal their most significant limitations: lower available bandwidth and limited computing power. Both of these limitations are addressed in this thesis. Available bandwidth on wireless networks fluctuates over time and is also shared among all users connecting to the same base station. In this work we present a dynamic bandwidth prediction model that makes short term predictions on the evolution of bandwidth. The model is dynamic and adjusts to the latest measurements provided by Zeus, a bandwidth measurement tool we designed and implemented on Nokia phones. The bandwidth predictions of our model are utilized in a novel rate control scheme, which we demonstrate to offer better performance than existing schemes. We next investigate the computing limitations of smartphones. A novel framework is considered, where computational tasks may be transferred to a central server and the results are fetched back at a later time. The central server has ample computing resources compared to the smartphones and the computing speedup outweighs the communication delays. The goal is to minimize the latency experienced by computational tasks, while judiciously utilizing the scarce memory resources available at the smartphone. Given the fluctuating nature of wireless bandwidth, there is a tradeoff between limited connectivity and congestion at the mobile. The second part of this thesis investigates resource control issues in wireline computing and more specifically in packet switches. Packet switches are essential parts of the Internet backbone and are also present in every data center. Modern data centers are severely constrained by their power consumption and power saving schemes would enable their further expansion. We propose novel power-aware scheduling algorithms for switches that offer significant power savings while sacrificing minimal performance. Finally, we examine a novel, scalable two-stage ingress memory switch architecture and we add backlog awareness to the scheduling algorithm to improve performance and fairness as perceived by the user.
