AIA IAS Research Review & Proposals July 14, 2006 Turgay Korkmaz Department of Computer Science UTSA

Overview of Previous Research 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 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 Integrated QoS and security mechanisms to support mission critical applications in MANETs
