Projects

We investigate variable client-thickness execution mechanisms for interactive scientific applications. We observe that such applications usually consist of a resource intensive number-crunching phase, followed by a highly interactive visualization phase. While it is desirable to execute the crunch phase at a remote location, where it can leverage higher computing power or better dataset accessibility, resulting thin-client interaction during the visualization phase will not yield necessary crisp responses. To attack this problem we employ virtual machine migration techniques to relocate the site of execution of the application in a manner transparent to the user. Collaboration with the group of Prof. M. Satyanarayan at Carnegie Mellon University.

We investigated simulation models and optimizations for Multihop Mobile Ad Hoc Networks (MANETs). Our findings include cross-layer mechanisms for resource discovery, MAC layer optimizations for interaction with TCP, self-interference alleviation mechanisms, development of highly-detailed propagation models for indoor simulation, and qualitative conclusions about the suitability of simplified simulation models.

Accurate indoor localization has long been an objective of the ubiquitous computing research community, and numerous indoor localization solutions based on 802.11, Bluetooth, ultrasound and infrared technologies have been proposed. We investigate the accuracy of GSM-based localization solutions for indoor environments. We have recently presented the first accurate GSM indoor localization system that achieves median accuracy of 5 meters in large multi-floor buildings.
