Aaditeshwar Seth, Patrick Darragh, Suihong Liang, Yunfeng Lin, and Srinivasan Keshav. An Architecture for Tetherless Communication. In Disruption Tolerant Networking. Dagstuhl Seminar Proceedings, Volume 5142, pp. 1-13, Schloss Dagstuhl – Leibniz-Zentrum für Informatik (2005)


In the emerging paradigm of tetherless computing, client applications running on small, inexpensive, and smart mobile devices maintain opportunistic wireless connectivity with back-end services running on centralized computers, enabling novel classes of applications. These applications require a communications infrastrastructure that is mobility-aware, disconnection-resilient and provides support for an opportunistic style of communiction. It should even be able to function across network partitions that may arise when end-to-end communication is not possible. We outline, design, and evaluate the implementation of an architecture that provides this functionality. we shot that it is possible for next-generation mobile devices to obtain up to 80-fold improvement over conventional mechanisms by exploiting opportunistic WiFi links, and that this benefit can be delivered as an overlay that is compatible with the current Internet.
