Brief Bio

Padma Mundur is a member of the research faculty at UMIACS. Prior to joining UMD, she was on the faculty of University of Maryland, Baltimore County (UMBC), CSEE Department. Padma got her Ph.D. from George Mason University (GMU), Fairfax, VA in May 2000. She received an M.E. from University of Virginia, Charlottesville, VA in 1990. Prior to GMU, she worked at Georgetown University Medical Center, Georgetown, Washington DC. She has a post-graduate degree from Indian Institute of Science, and an undergraduate degree in engineering from Bangalore University, Bangalore, India. During her tenure at UMBC, Padma taught graduate and undergraduate courses on Databases, Computer Networks, Multimedia Systems, and Modeling and Simulation. Among her professional activities, she has served on numerous program committees, performed reviews for journals and funding panels. She currently serves on the editorial board of IEEE Communications Surveys & Tutorials Journal(Impact Factor is 3.692 and ranking in the telecommunications area is 3 out of 80).

Curriculum Vitae

Research

Padma's research over the years has focused on network modeling and protocol design, multimedia networking and video server design, mobile multimedia, distributed systems, and analytical resource allocation and performance models.

At UMIACS, her research is on the topic of Delay Tolerant Networks (DTNs), funded by the Laboratory for Telecommunications Sciences (LTS). These networks present interesting challenges to implementing the TCP/IP protocols requiring alternative ideas and concepts. The difficulty arises due to intermittent connectivity within the network leading to an absence of end-to-end paths for routing and other services. The specific focus of Padma's research has been to design and implement new routing algorithms and protocols for DTNs. Her current project involves building a mobile wireless testbed that can be used to evaluate many DTN protocols and applications. Many of the recent publications linked below provide details of this research work.

Virtual MeshTest Testbed (VMT) Project: This project deals with building a scalable mobile wireless testbed in a laboratory setting for evaluating a host of applications for DTNs. The core idea behind the testbed project is to use node virtualization and live migration to achieve scalability. A plan for the testbed implementation describing that core concept was published in ExtremeCom 2009. More recent publications describing the testbed architecture and implementation are given below. Demos of the testbed were presented in HotMobile 2010 and Chants 2010.

The VMT team consists of researchers Brenton Walker (LTS), Padma Mundur (UMIACS), and UMD GRAs Carson Dunbar, Keith Taylor, and Jonathan Jesuraj. Past students include Ginnah Lee, Kun Lin, Dongwoon Hahn, Inkeun Cho, and Youngil Kim. Other collaborators at LTS include Matt Seligman, Calvin Ardi, and Matt Beecher.
