Jack L. Burbank leads the Wireless Networking section within
the Communications and Network Technologies group of The Johns
Hopkins University Applied Physics Laboratory (JHU/APL). Mr.
Burbank is an expert in the areas of wireless networking and
modeling and simulation, focusing on the application and evaluation
of wireless networking technologies to the military context. His
team of network engineers at JHU/APL participates within the
Internet Engineering Task Force (IETF) and the IEEE 802 standards
organization. Mr. Burbank is a professor of networking and
telecommunications in The Johns Hopkins University Part-Time
Engineering Program, and is a member of the IEEE and ASEE.

William T. Kasch received a B.S. in Electrical
Engineering at the Florida Institute of Technology in 2000 and an
M.S. in Electrical and Computer Engineering at the Johns Hopkins
University in 2003. His interests include various aspects of
wireless networking, including MANET, IEEE 802 technology, and
cellular. He participates actively in both the IEEE 802 standards
organization and the Internet Engineering Task Force.

Jon R. Ward works in the wireless networking section of
the communications and networking technology (VCT) group atT he
Johns Hopkins University Applied Physics Laboratory (JHU/APL) in
Laurel, MD. He has worked projects focusing on network design and
interference testing of standards-based wireless technologies such
as IEEE 802.11, IEEE 802.15.4, and IEEE 802.16.
