Energy‐Efficient Protocol Design

Abstract

Recent studies have shown that the total energy consumed by the Internet has followed an increasing trend over the years. A considerable part of this energy is wasted due to an inefficient utilization of edge devices, i.e., Personal Computers (PCs) and other user equipment in homes and offices. PCs are often left on even when they are not used (e.g., overnight or during weekends), while other edge devices, such as printers, IP phones, and displays, are typically kept always on, especially in public buildings. A number of solutions have been proposed for eliminating, or reducing, energy wastes due to edge devices. In this chapter we propose a general taxonomy for their classification. Then, according to the introduced taxonomy, we survey the main proposals appeared in the literature. Finally, we highlight some open issues.

Power Profiling of Context Aware Systems: A Contemporary Analysis and Framework for Power Conservation

“…The power awareness at the OS level can be termed as 'battery-aware' as it considers the discharge management by the complete system rather than the applications [56]. This technique is implemented as a rule based system (RBS) using mapping and is limited to finetuning at the application level [57,58].…”
