The application of mathematical analysis to wireless networks has met with limited success, due to the complexity of mobility and traffic models, coupled with the dynamic topology and the unpredictability of link quality that characterize such networks. The ability to model individual, independent decision makers whose actions potentially affect all other decision makers makes game theory particularly attractive to analyze the performance of ad hoc networks. Game theory is a field of applied mathematics that describes and analyzes interactive decision situations. It consists of a set of analytical tools that predict the outcome of complex interactions among rational entities, where rationality demands a strict adherence to a strategy based on perceived or measured results. In the early to mid-1990's, game theory was applied to networking problems including flow control, congestion control, routing and pricing of Internet services. More recently, there has been growing interest in adopting game-theoretic methods to model today's leading communications and networking issues, including power control and resource sharing in wireless and peer-to-peer networks. This work presents fundamental results in game theory and their application to wireless communications and networking. We discuss normal-form, repeated, and Markov games with examples selected from the literature. We also describe ways in which learning can be modeled in game theory, with direct applications to the emerging field of cognitive radio. Finally, we discuss challenges and limitations in the application of game theory to the analysis of wireless systems. We do not assume familiarity with game theory. We introduce major game theoretic models and discuss applications of game theory including medium access, routing, energy-efficient protocols, and others. We seek to provide the reader with a foundationalunderstanding of the current research on game theory applied to wireless communications and networking.

Over the past few years the wireless technology industry has seen massive growth with ever increasing mobile subscriber rates. Simple analog radio tools have evolved into sophisticated adaptive technologies. These now employ advanced hardware, modulation and coding techniques and processing solutions, unimaginable a decade ago. Network designs based on CDMA 2000 are becoming extremely complex and highly standardized. Designing CDMA 2000 Systems provides engineers with the background information needed to understand the CDMA 2000 technology, by describing design techniques and available algorithms. This book: *Covers the main standards involved in the technology specification whilst focussing on those aspects required for the design of CDMA systems. *Describes in detail the structure of CDMA 2000 systems and provides guidelines for their optimisation. Written in a thorough and knowledgeable manner this book fills a gap in the information available today and will serve as a reference for designers and operators. Its specialist coverage from introductory to advanced level serves as an excellent 'how to' manual for all those looking for one complete source on CDMA 2000.
