Mobile terminals such as cellular phones, smart phones and PDAs require wireless connection to exchange information with the external world. In this tutorial we focus on wireless packet networks based on the IEEE 802.11b protocol, commonly used to build local area networks of palmtop and notebook computers. Due to limited battery lifetime of mobile terminals, energy consumption of wireless interfaces becomes a critical design constraint. Within the IEEE 802.11 standard, power conservation protocols have been implemented that trade power for performance. In this tutorial, we present a power-accurate model of wireless network interface card that allows the power/performance trade-off to be studied as a function of traffic patterns imposed by the applications. The model has been validated against measurements on real hardware devices.

Abstract
Mobile terminals such as cellular phones, smart phones and PDAs require wireless connection to exchange information with the external world. In this tutorial we focus on wireless packet networks based on the IEEE 802.11b protocol, commonly used to build local area networks of palmtop and notebook computers. Due to limited battery lifetime of mobile terminals, energy consumption of wireless interfaces becomes a critical design constraint. Within the IEEE 802.11 standard, power conservation protocols have been implemented that trade power for performance. In this tutorial, we present a power-accurate model of wireless network interface card that allows the power/performance trade-off to be studied as a function of traffic patterns imposed by the applications. The model has been validated against measurements on real hardware devices.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
