My research interests lie broadly in networked systems. I have conducted research on several topics including mobile and wireless networking, content distribution, peer-to-peer systems, Internet architecture, protocol design and analysis, datacenter systems, and network measurement. Some of my recent research efforts are:
- MobilityFirst: This "Future
Internet Architecture" effort seeks to design an implement a
future Internet with mobility and trustworthiness as central design
goals. I am co-leading the MobilityFirst architecture in
collaboration with Rutgers and several other institutions. Check out
page for an overview.
- Robust wireless stack: Seeks to develop a robust protcol stack for diverse wireless networks ranging from well-connected mesh networks to to highly mobile, vehicular, or disruption-tolerant networks.
- Routing: R3 (MobiCom'11) ensures robust routing performance in any kind of a multi-hop wireless network. R3 builds upon our work on RAPID (IEEE/ACM ToN'10, Sigcomm'07), one of the first DTN routing protocols validated by real deployment.
- Transport: Hop (NSDI'09) is a "block-switched" hop-by-hop transport protocol that dramatically outperforms TCP and is robust to routing disruptions.
- Mobile P3: Seeks to optimize performance, price, and power consumption in a multi-technology mobile world. Check out our work on TailEnder (IMC'09) to optimize 3G power consumption, and Wiffler (MobiSys'10) to balance performance and 3G usage.
- Content networking: Our recent paper (Infocom'11) reveals surprising implications of replicated content on ISP traffic engineering.
