RESEARCH

Scalable Network Systems:

I am conducting research on the design and analysis of Large Scale Network Systems. In particular, we are studying the structure and performance of overlays in the presence of selfish users. In our initial work, we identified the causes and implications of Mistreatment in distributed caching groups, and we designed a novel framework to mitigating mistreatment in such groups (see Distributed Selfish Caching). In a collaborative effort, we are designing scalable algorithms for Service Deployment in the Internet-scale. In the past, we have studied the robustness of resource-reduced routers in the presence of aggressive high speed transport protocols (see The Effect of Router Buffer Size on the end-to-end Protocols Performance ) and we designed distributed leader election mechanisms to prolong the lifetime of heterogeneous wireless networks (see SEP: A Stable Election Protocol for clustered heterogeneous wireless sensor networks).

Network Statistics:

I am interested in applying, in collaboration with colleagues from other disciplines, Statistical Methods in the Networking arena. We are designing efficient Network Sampling techniques for fast and efficient Network Discovery.We are also applying Large Deviations Asymptotic results to rigorously identify, in real-time, Network Anomalies (see A Large Deviations Approach to Network Anomaly Detection).
