Measuring and Reducing Energy Consumption of Network Interfaces in Hand-Held Devices (Special Issue on Mobile Computing)

This paper measures usage of two PDAs, the Apple Newton Messagepad and Son y Magic Link, and four NIs, the Metricom Ricochet Wireless Modem, the A T&T Wavelan operating at 915 MHz and 2.4 GHz, and the IBM Infrared W ireless LAN Adapter to examine two classes of optimizations that can be used to reduce netw ork interface energy consumption.
