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 RD, 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

Hardware Projects Cognitive Radio and MUSE

• MUSE Multimodal Sensors
• First system-level MUSE prototype completed 11/03
• New ECG interface board
• CerfCube platform with 802.11b (off-the shelf
  components)
• WINLAB drivers networking software
• Next steps
• Make this prototype available to BioMed and UMDNJ
  collaborators
• Integrate with ZnO devices
• Continue work towards MUSE sensor SoP/SoC with
  low-power 802.11b

• Cognitive Radios
• Network Centric concept for cognitive radio
  prototype, integrating agile RF/adaptive modem
  with network processing for etiquettes and
  multi-hop collaboration
• Joint NSF NeTS proposal with Bell Labs (Dr. T.
  Sizer) and GA Tech (Prof. Lasker) to develop
  flexible cognitive radio platform

PARIS DARWIN Securing Wireless Networks

• DARWIN Defenses for Attacks of
  Radio-interference on Wireless Networks
• Wireless networks may be subjected to jamming
  attacks that prevent wireless communication.
• Defense Strategies Channel Surfing and Spatial
  Retreats.

• 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!

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
