Abstract
An important issue to be addressed for the next generation of wirelessly-connected hand-held devices is battery longevity. In this paper we examine this issue from the point of view of the Network Interface (NI). In particular, we measure the power usage of two PDAs, the Apple Newton Messagepad and Sony Magic Link, and four NIs, the Metricom Ricochet Wireless Modem, the AT&T Wavelan operating at 915 MHz and 2.4 GHz, and the IBM Infrared Wireless LAN Adapter. These measurements clearly indicate that the power drained by the network interface constitutes a large fraction of the total power used by the PDA. We also conduct trace-driven simulation experiments and show that by using application-specific policies it is possible to ...
