Free registration required

Executive Summary

Understanding and optimizing the energy consumption of wireless devices is critical to maximize network lifetime and to provide guidelines for the design of new protocols and interfaces. In this paper, the authors first provide an accurate analysis of the energy performance of an IEEE 802.11 WLAN, and then they derive the configuration to maximize it. They also analyze the impact of the energy configuration of the device on the throughput performance, and discuss in which circumstances throughput and energy efficiency can be both maximized and where they constitute different challenges.
