Game Theory in Wireless and Communication Networks

Abstract

This unified treatment of game theory focuses on finding state-of-the-art solutions to issues surrounding the next generation of wireless and communications networks. Future networks will rely on autonomous and distributed architectures to improve the efficiency and flexibility of mobile applications, and game theory provides the ideal framework for designing efficient and robust distributed algorithms. This book enables readers to develop a solid understanding of game theory, its applications and its use as an effective tool for addressing wireless communication and networking problems. The key results and tools of game theory are covered, as are various real-world technologies including 3G networks, wireless LANs, sensor networks, dynamic spectrum access and cognitive networks. The book also covers a wide range of techniques for modeling, designing and analysing communication networks using game theory, as well as state-of-the-art distributed design techniques. This is an ideal resource for communications engineers, researchers, and graduate and undergraduate students.

Opportunistic Spectrum Utilization in Vehicular Communication Networks

“…To utilize the licensed spectrum, vehicles should opportunistically access the channels with different ECAs in a distributed manner. Game theory [126] is a well-known tool to analyze the behavior of distributed players who are considered to be selfish and rational. We apply a noncooperative congestion game to model the spectrum access process in CR-VANETs, in which vehicles in a cluster choose channels to access in a distributed manner, trying to maximize their own utilities.…”

Shannon meets Walras on interference networks

“…The decoding order is as follows: First, the public message of the other link and then, the own public and finally the own private message is decoded. For the Gaussian interference channel, the following conditions [16,Chapter 6] limit the achievable rates for the 1 Such a meeting between Shannon and Walras could not happen because Shannon was born six years later than Walras has died. interference channel…”

“…Proposition 1. The utility function u 1 defined in (9) is 1) strongly increasing in λ (1) and 2) quasi-concave in λ (1) .…”

“…However, the UMP can be formulated and solved in closed form. For h 11 <h 1 , the utility function u 1 in (16) is strongly decreasing in λ (1) 1 , by a change of variables a modified strongly increasing and strictly quasi-concave utility function can be developed.…”

“…One approach to study the conflict situation of coexistence and resource sharing on the physical layer is based on game theory [1]. Depending on the system operation, non-cooperative or cooperative game theory is applied.…”
