Graduate Research Assistant, Georgia Institute of Technology, Atlanta, GA (01/01 – 05/04)

Advisor: Dr. John Copeland

Dissertation Research: Mathematically analyzed tree based collision resolution mechanisms, including

the Home PNA 2.0 MAC. Proposed a QoS MAC framework for contention based medium access in

CSMA local networks. The proposed ‘implicit scheduling’ framework uses a more deterministic channel

access method than traditional randomized methods. The determinism is achieved through compact state-

keeping of channel access history and by using specific access rules. Our protocol achieves strong

hierarchical fairness with efficient channel utilization.

Network Security Research: Proposed a novel method for detecting rogue 802.11 WLAN access points

by comparing inter-packet temporal spacing in the rogue environment versus that in a normal wired LAN

environment.
