The Design and Evaluation of a Storage System for Pervasive Computing

Many interesting pervasive applications require the maintenance of state, but few pervasive computing systems provide a compelling system for managing such state. Although conventional storage abstractions can fill some of these needs, the unique character of the pervasive environment suggests slightly different answers. Pervasive applications often have to work with data in forms they were not directly coded to support, need to be able to extend the behavior of existing applications, and must support mobility across a wide range of devices. The one.world storage architecture supports the needs of pervasive computing and overcomes many of these limitations in other systems. This paper examines the design decisions made in the one.world storage architecture and API and provides an initial look at the lessons learned from the implementation of this design.
