Message Ferrying (MF) is a technique used to deliver data in wireless and mobile networks that are either sparse or intermittently connected. The scheme utilizes a set of mobile nodes called message ferries that take responsibility for carrying messages within the network. I will first describe the context in which the MF scheme is relevant. I will then discuss the problems that one faces in the design and operation of networks using message ferries and our approach to solving them.

Mostafa Ammar is a Regents' Professor with the School of Computer Science at the Georgia Institute of Technology. He has been with Georgia Tech since 1985 and has served as Associate Chair of the School of Computer Science since 2006. Dr. Ammar received the S.B. and S.M. degrees from the Massachusetts Institute of Technology in 1978 and 1980, respectively and the Ph.D. from the University of Waterloo, Ontario, Canada in 1985. Dr. Ammar's research interests are in network architectures, protocols and services. He has contributions in the areas of multicast communication and services, multimedia streaming, content distribution networks, network simulation and, most recently, in intermittently-connected wireless networks and overlay network design. He has published extensively in these areas. To date, 29 PhD students have completed their degrees under his supervision; many have gone on to distinguished careers in academia and industry. Dr. Ammar has served the networking research community in multiple roles. Most notably, he served as the Editor-in-Chief of the IEEE/ACM Transactions on Networking (ToN) from1999 to 2003, and he was the co-TPC Chair for the IEEE ICNP 1997, ACM CoNEXT2006 and ACM SIGMETRICS 2007 conferences. He currently serves on the steering committees of ToN and CoNEXT. Dr. Ammar was elected Fellow of the IEEE in 2002 and Fellow of the ACM in 2003.
