Executive Summary

Energy efficiency takes important in wireless communication systems where networked low-power devices relying on batteries should be able to communicate transparently. Current wireless network power management often substantially degrades performance and may increase overall energy usage when used with latency-sensitive applications. The authors propose power management that adapts its behavior to the access patterns and intent of applications, the characteristics of the network interface, and the energy usage of the platform. They have implemented software for power management as a windows family module - their results show substantial benefits for distributed file systems and thin-client applications.
