TAPs: An Architecture and Protocols for a High-Performance Multi-hop
Wireless Infrastructure
Ed Knightly
While high-speed wireless access is easy to achieve in an enterprise
network via low-cost IEEE 802.11 (WiFi) access points, wireless
technology in public spaces is in its infancy. ``Hot spots'' provide
high-speed wireless access, but do so in very few isolated ``islands''
at immense costs. Likewise, while fixed wireless and 3G can provide
ubiquitous coverage and 3G can support mobility, throughputs can often
be two orders of magnitude slower than WiFi. In this talk, I will make
the case for the requirement of a fundamental new architecture based on
beamforming antennas deployed on fixed, Transit Access Points (TAPs) that
form a multi-hopping wireless backbone with a limited number of wired
ingress/egress points. Moreover, I will describe a number of research
issues including opportunistic and coordinated resource management and
a ``network is the channel'' framework that searches for fundamental
information-theoretic tradeoffs between protocol overhead and capacity.
Bio
Edward Knightly is an associate professor in the ECE and CS Departments
at Rice University. He received the B.S. degree from Auburn University
in 1991 and the M.S. and Ph.D. degrees from the University of California
at Berkeley in 1992 and 1996 respectively. He is an associate editor of
the Computer Networks Journal and IEEE/ACM Transactions on Networking,
and previously, IEEE Transactions on Multimedia and IEEE Network Magazine.
He served as co-chair of IWQoS 1998 and on the steering committee for
IWQoS from 1999-2001. He served as finance chair for ACM MOBICOM 2002
and 2003, tutorial co-chair for IEEE ICNP 2001 and MOBIHOC 2003, and
on the program committee for numerous networking conferences including
ICNP, INFOCOM, IWQoS, MOBICOM, and SIGMETRICS. He received the National
Science Foundation CAREER Award in 1997 and the Sloan Fellowship in 2001.
He will be technical co-chair of INFOCOM 2005. His research interests are
in the areas of mobile and wireless networks, high-performance protocol
design, quality of service, and performance evaluation.
