4.1 Introduction

Wireless networks have become more and more popular because of ease of installation, ease of access, and support of smart terminals and gadgets on the move. Energy-efficient wireless network operation is without doubt of high importance, both for infrastructure and for ad-hoc communication. While for infrastructure networks, economic and ecological considerations are predominant and the networking components are often connected to the power grid, ad-hoc networks mainly rely on limited battery-powered components and, thus, the network's lifetime and availability is challenged. Similarly, the energy depletion of mobile client devices such as smartphones is a crucial challenge, as they are the user interface to ubiquitous connectivity.

In the overall life cycle of providing green ...
