== Abstract ==
To maximize capacity and reliability in large-scale wireless mesh networks,
it is critical to intelligently control transmit power and coordinate
airtime consumption. We have developed distributed algorithms to perform
congestion detection and per-packet bit rate and power control to provide
reliable performance under extreme load conditions. Comparisons in
real-world city-wide networks demonstrate their effectiveness.

Cyrus Behroozi is Tropos Networks' Chief Scientist. After joining in
2000, he developed the company's first wireless mesh hardware. More
recently he has focused on network performance, developing advanced
distributed algorithms for route selection, power and bit rate
control, airtime coordination, and channel selection. Mr. Behroozi
draws upon his background in experimental physics for insight into
electromagnetic propagation and complex systems. At Harvard
University, he was part of the research team that slowed light to 38
miles per hour in a Bose-Einstein condensate and subsequently stopped
it outright. He co-authored two articles in Nature on this work.

Mr. Behroozi holds a BS in Physics from the California Institute of
Technology and an AM in Applied Physics from Harvard University.
