2. 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 couplethem 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. • Outcome • Turgay Korkmaz, Wei Zhou, "On Finding Optimal Paths in Multi-radio, Multi-hop Mesh Networks using WCETT Metric", International Wireless Communications and Mobile Computing Conference IWCMC 2006, ACM.  July 3 - 6, 2006.

3. 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
