DTN Routing and Capacity Enhancement in an Outdoor Mobile Environment

Delay-Tolerant Networks (DTNs) enable routing when mobile nodes are sparsely populated and connect only intermittently. These include networks that attempt to survive large-scale natural disasters, sensor deployments for ecological monitoring, ocean sensor networks, and vehicular networks supported by wireless meshes.

At UMass Amherst we have focused on designing, building, and deploying large-scale DTN systems and protocols. We have deployed a 40-node DTN operating on a public transit system, called DieselNet. We are expanding this deployment to include ad hoc vehicular nodes, such as safety workers, and a Town-wide wireless mesh network. Furthermore, we are deploying our DTN technology in monitoring system for endangered turtles in western Massachusetts. In this talk, we will discuss our DTN deployment experience and two technical contributions: novel, utility-based routing protocols and adding capacity to the network with energy-efficient devices we call throwboxes.

Mark Corner has been an Assistant Professor in the Computer Science Department at the University of Massachusetts-Amherst since 2003 after graduating with his PhD in Electrical Engineering from the University of Michigan. His primary interests lie in the areas of mobile and pervasive computing, networking, file systems and security. He was the recipient of an NSF CAREER award in 2005, a Best Paper at ACM Multimedia 2005, as well as the Best Student Paper Award at Mobicom 2002. Prof. Corner’s work is supported by the NSF, DARPA, and the NSA.

Brian Neil Levine is currently an Associate Professor in the Department of Computer Science at the University of Massachusetts Amherst, which he joined in 1999. He received a PhD from the University of California, Santa Cruz. In the networking area, his research focuses on mobile systems and peer-to-peer networking. In the security area, his research is focused on privacy, including anonymous routing protocols. He was awarded an NSF CAREER grant in 2001 for work in peer-to-peer networking. In 2004, he was awarded a Lilly teaching fellowship from UMass Amherst. Levine is an associate editor of the IEEE/ACM Transactions on Networking, and was co-chair of NOSSDAV in 2006.
