Title:       Power-aware Routing and Scheduling

Power efficiency has emerged as an important concern in the design and
operation of networks. One important concept is rate adaptivity, or
"power follows load", using low power in times of low traffic and
higher power in times of heavier traffic.

Power-follows-load can be accomplished globally by rerouting traffic
streams to minimize network-wide power consumption. The resulting
problem is a multi-commodity flow problem where the cost function
displays diseconomies of scale. For this problem we present a
polylogarithmic approximation.

Another approach takes place at a local level by adjusting the clock
speed of each individual network element, and hence its power
consumption as a function of traffic.  In this context, we study how
to devise rate-setting algorithms in combination with existing
scheduling policies to achieve power minimization against competing
goals such as network stability, delay and queue minimization.

This work is joint with Spyros Antonakopoulos and Lisa Zhang.
