Wireless Information Network Laboratory 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: Privacy Augmented Relaying of

Information from SSensors: 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!

WINLAB Prototypes: ORBIT Testbed Open-access next-generation wireless network testbed being developed at Rutgers for NSF network

research testbeds (NRT) program Large scale “radio grid emulator” for evaluating new concepts for future wireless networks, e.g. ad-hoc

sensor nets, pervasive systems... Also, outdoor “field trial network” covering RU Busch & NB campuses for real-world application work
