RESEARCH

Coordination Systems for Datacenter Networks

 Fall 2010 - Present
Designing and implementing a coordination framework for networked systems. The framework builds upon a new object-oriented approach that proposes using application-specific coordination objects.
Advisor: Prof. Emin Gün Sirer


Improving Internet Archive File System Performance

 Fall 2009 - Summer 2010
Analyzed Internet Archive data sets for common spatial and temporal localities and built a cache simulator to observe potential improvements in terms of energy efficiency by being able to turn off unused discs.
Advisor: Prof. Hakim Weatherspoon


SCALAR & ScalarUp: Scalable data lookup and reactive replication framework

 Fall 2008 - Spring 2009
Worked on a scalable and reactive data replication framework, SCALAR. Later, enhanced the proposed framework to take data updates into consideration. The study employed extensive simulations on Scalable Wireless Ad hoc Network Simulator (SWANS).
Advisor: Prof. Öznur Özkasap
