Understanding and optimizing the energy consumption of wireless devices is critical to maximize the 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 optimize it. They further analyze the impact of the energy configuration of the stations on the throughput performance, and they discuss under which circumstances throughput and energy efficiency can be both jointly maximized and where they constitute different challenges.
