Abstract
Optical Networking with Wavelength Division Multiplexing (WDM) has
immense potential to satisfy the future needs of both military and
commercial avionic communication systems, in large part due to the
high bandwidth provision, low electromagnetic interference, and light
weight. However, fiber optic components are susceptible to faults,
particularly in the hazardous working conditions of avionic systems.
There is a need to design appropriate network level architectures that
are able to offer fault tolerant operations, wavelength assignment and
routing and that leverage the advantageous features of WDM
technologies. In this talk, a torus-based fault-tolerant all-optical
architecture is discussed that applies four optimal non-overlapping
light-paths to achieve a fast 3-failures-free protection. To minimize
wavelength utilization. A wavelength allocation and reuse scheme is
presented as well. The proposed network architecture provides fault
tolerance performance improvement that is demonstrated via a
comprehensive connection reliability and network capacity analysis.

Electrical & Computer Engineering at the University of Florida, where
she leads the Wireless And Mobile (WAM) Systems Laboratory. She earned
her B.S. and M.S. in electrical engineering from the University of
Texas at Austin in 1991 and 1993, respectively, and her Ph.D. in
electrical and computer engineering from the Georgia Institute of
Technology in 2000. Currently, she serves on the Editorial Board of
the Elsevier Ad Hoc Networks Journal and the Springer Wireless
Networks Journal, has served as session chair for several years at the
IEEE Military Communications Conference, and is currently publications
chair for IEEE INFOCOM 2012. Dr. McNair has participated in several
DoD-related communications research projects, including an avionic WDM
LAN study for the US Navy and as a participant in the 2008 DARPA
Computer Science Study Group. Her current research interests are next
generation networks, including WDM, small satellite networks, and
cognitive networks, specifically addressing security, routing and
medium access control.
