Ram Ramanathan is a Principal Scientist in the Internetworking Research Department at BBN Technologies. His primary area of expertise is Mobile Ad Hoc Networking (MANET) in which he has had more than 14 years of advanced research and development experience. He has made significant contributions to several areas -- topology control, use of directional antennas, and scalable flat routing for MANETs.
Dr. Ramanathan's recent research areas include new MANET architectures, disruption tolerance, software radios, opportunistic spectrum access, topology control, beamforming antennas, and medium access control. Over the past few years, he has led several projects on advanced ad hoc networking for the Defense Advanced Research Projects Agency (DARPA). He has been the Principal Investigator for the DARPA project neXt Generation Communications (XG) which seeks to develop technologies for opportunistic spectrum access for cognitive radios. He was the co-Prinicpal Investigator of the DARPA project Utilizing Directional Antennas for Ad Hoc Networking (UDAAN), as part of which the first prototype ad hoc networking system with directional antennas was designed, simulated and field-demonstrated. Prior to that he was the PI for the DAWN project under the DARPA GloMo program. Currently, he is working on the DARPA WNAN program which seeks to build a very large MANET with Dynamic Spetrum Access and DTN support using inexpensive nodes each consisting of up to four frequency-agile radios. He is also part of the Network Science CTA program where he is working on operational capacity and dynamic network structures.
Ram has served on the program committees of several top-tier conferences including ACM MobiCom, Mobihoc and IEEE Infocom, and is on the editorial board of IEEE Transactions on Mobile computing. He was the TPC co-chair of ACM Mobicom 2007. He has published over 40 refereed papers in international journals and conferences, including best paper award winning papers at IEEE MILCOM, IEEE INFOCOM, and ACM SIGCOMM. Ram received his Bachelor of Technology in Electrical Engineering from the Indian Institute of Technology, Madras, and received his M.S and Ph.D degrees in Computer and Information Sciences from the University of Delaware. respectively.
