Overview of Previous Research
Power-efficient mechanisms for detecting
replay-based intruders in wireless ad hoc
networks

• Research Objective
• Investigate how to combat against replay-based
  attacks that cannot be just dealt with using
  cryptographic techniques
• Develop a protocol to verify physical presence of
  neighboring wireless nodes
• Progress
• We first consider RTT-based and power-based
  approaches. We then couple them to design an
  effective neighbor verification protocol (NVP).
• With the extension of this grant, we start
  investigating topology control, MAC and QoS
  issues in wireless ad hoc networks.

Proposed Research
Integrated QoS and security mechanisms to support
mission critical applications in MANETs

• Objective
• Despite their potential benefits, MANETs are
  currently not able to meet the stringent security
  and quality-of-service (QoS) requirements in
  military settings. In this project, we
  investigate these two key issues and integrate
  them so that various attacks can be
  detected/avoided during the QoS-aware operations
  of the network.
• Approach
• Develop basic mechanisms such as traffic
  prioritization and packet authentication at MAC
  layer. (We have some preliminary work here and
  continue to improve it)
• Consider soft QoS techniques across transport,
  network and data link layers
• Consider behavior monitoring to combat both
  outsider and internal attacks
• Budget
• Two Graduate students 50,000 (12-month
  stipend and tuition)
• Faculty summer support 24,000 (two-month
  salary and fringe benefits)
• Travel 5,000 (3000 for faculty and 2000
  for students)
• Supplies/Materials 1,000
