Opportunistic spectrum access (OSA) has been regarded as the most promising approach to
solve the paradox between spectrum scarcity and waste. Intelligent decision making is key …

This paper surveys the recent findings in the area of energy efficient radio resource
management in cellular networks. The primary objective is to identify and evaluate the key …

After about a decade of intense research, spurred by both economic and operational
considerations, and by environmental concerns, energy efficiency has now become a key …

This monograph presents a unified framework for energy efficiency maximization in wireless
networks via fractional programming theory. The definition of energy efficiency is introduced …

Both cognitive radio and femtocell have been considered as promising techniques in
wireless networks. However, most of previous works are focused on spectrum sharing and …

This paper addresses the problem of energy-efficient resource allocation in the downlink of
a cellular orthogonal frequency division multiple access system. Three definitions of energy …

Used to explain complicated economic behavior for decades, game theory is quickly
becoming a tool of choice for those serious about optimizing next generation wireless …

Defensive and offensive capabilities are both significant in communication confrontation
games. By exploiting the above two capabilities, a new confrontation mechanism in the …

Heterogeneous wireless networks are considered as promising technologies to improve
energy efficiency. In heterogeneous networks, interference management is very important …

While still early in its development, cognitive radio is a highly promising communications
paradigm that can effectively address the spectrum insufficiency problem. This book …
