
Cooperative industry-university research center at
Rutgers University, focused on wireless technology
In operation since 1989, with a strong track record of
research contributions to wireless data networking
Research program a mix of core R&D, focus projects
and industry collaboration
~15-20 Industry sponsors, NSF, NJCST, …
~20 faculty/staff + ~40-50 students
Starting in Fall 2001, WINLAB has executed a strategic
growth plan that has significantly increased research
scope/activity and taken the center into new areas such
as sensor technology and ad-hoc networking…

PARIS & DARWIN: Securing Wireless Networks
PARIS: Privacy Augmented Relaying of
Information from Sensors:


Issues that arise because an adversary
observes the context surrounding
creation/transmission of wireless message.
For tactical networks, Source-Location
Privacy focuses on protecting the
networked soldier from traceback attacks
by adversaries!
DARWIN: Defenses for Attacks of Radiointerference on Wireless Networks


Wireless networks may be subjected to
“jamming” attacks that prevent wireless
communication.
Defense Strategies: Channel Surfing and
Spatial Retreats.
