My research focuses on developing models and methodologies for simulation and performance evaluation of urban mesh networks. The models developed include the propagation model, model for time-varying channels and the mobility model. The propagation model is based on ray-tracing and accounts for path-loss, delay-spread and other key metrics. The time-varying channel is modeled using diffusion process and estimates the channel variability in a dynamic environment. The mobility model is based on a large number of surveys of civilian mobility including data from the US Bureau of Labor Statistics and Department of Transportation.

By making use of the above models performance of application layer protocols such as http, ftp, music streaming and VoIP are evaluated in an urban mesh network setting.

In order to enhance the routing performance in presence of remotely accessible nodes a novel paging scheme, that utilizes the graphical structure introduced by the urban structure has been developed.

During my tenure as "Interim Engineering Intern" at Qualcomm Inc. I worked on various aspects of cellular and wlan integration. Specifically I worked on devloping seamless handoff mechanisms from wlan to cellular system.
