This book focuses on the emerging research topic "green (energy
efficient) wireless networks" which has drawn huge attention recently
from both academia and industry. This topic is highly motivated due to
important environmental, financial, and quality-of-experience (QoE)
considerations. Specifically, the high energy consumption of the
wireless networks manifests in approximately 2% of all CO2 emissions
worldwide. This book presents the authors' visions and solutions for
deployment of energy efficient (green) heterogeneous wireless
communication networks. The book consists of three major parts. The
first part provides an introduction to the "green networks" concept, the
second part targets the green multi-homing resource allocation problem,
and the third chapter presents a novel deployment of device-to-device
(D2D) communications and its successful integration in Heterogeneous
Networks (HetNets).
The book is novel in that it specifically targets green networking in a
heterogeneous wireless medium, which represents the current and future
wireless communication medium faced by the existing and next generation
communication networks. The book focuses on multi-homing resource
allocation, exploiting network cooperation, and integrating different
and new network technologies (radio frequency and VLC), expanding the
network coverage and integrating new device centric communication
paradigms such as D2D Communications. Whilst the book discusses a
significant research topic supported with advanced mathematical
analysis, the resulting algorithms and solutions are explained and
summarized in a way that is easy to follow and grasp. This book is
suitable for networking and telecommunications engineers, researchers in
industry and academia, as well as students and instructors.
