An Architecture for Tetherless Communication Seth, Aaditeshwar Darragh, Patrick Liang, Suihong Lin, Yunfeng Keshav, Srinivasan Delay tolerant networks Opportunistic communication Tetherless computing Wireless Mobile 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.
