Cross‐layer optimization for energy‐efficient wireless communications: a survey

TLDR

Battery technology lags semiconductor progress, making power efficiency a critical concern in wireless networking alongside traditional metrics such as bandwidth and throughput. This article provides a comprehensive survey of recent advances in cross‑layer design for energy‑efficient wireless communications. The survey focuses on system‑based approaches to energy‑optimal transmission and resource management across time, frequency, and spatial domains, and also reviews energy‑efficient hardware implementations. © 2008 John Wiley & Sons, Ltd.

Abstract

Abstract Since battery technology has not progressed as rapidly as semiconductor technology, power efficiency has become increasingly important in wireless networking, in addition to the traditional quality and performance measures, such as bandwidth, throughput, and fairness. Energy‐efficient design requires a cross layer approach as power consumption is affected by all aspects of system design, ranging from silicon to applications. This article presents a comprehensive overview of recent advances in cross‐layer design for energy‐efficient wireless communications. We particularly focus on a system‐based approaches toward energy optimal transmission and resource management across time, frequency, and spatial domains. Details related to energy‐efficient hardware implementations are also covered. Copyright © 2008 John Wiley & Sons, Ltd.
