Research

My research interests are mainly in the areas of security, quality of service (QoS), and resource management in wireless networks. Specifically, the thrust has been the following:

(a) Identification of protocol vulnerabilities in WiFi, WiMAX, ad hoc wireless, RFID, sensor and smartphone networks;
(b) Design of security best practices, risk mitigation and analysis, and the design of intrusion detection and prevention mechanisms;
(c) Cryptographic algorithms for group key management in resource-constrained networks;
(d) Enhancement of QoS in 3G+ wireless networks, optical burst switching techniques for QoS, and performance analysis of wireless networks.

Recently, I have explored the vulnerabilities, reliability issues and applications of RFID systems, NFC-enabled smartphones and sensor networks and obtained preliminary results for body area networks.

The research has been supported by NSERC and Industry Canada. This has also been complemented by industry collaborations with local private sector companies such as SheepdogInc.ca, Timeless Medical Systems, SolutionInc., and DSM Telecommunications.
