The demand for network-enabled limited-footprint mobile devices is increasing rapidly. A central challenge that must be addressed in order to use these next-generation devices effectively is efﬁcient data management – persistent data manipulated or required by applications executing on these computationally and communicationally impoverished devices must be consistently managed and made highly available. This data management has traditionally been the responsibility of the OS on which applications execute. In this paper, we extend this conventional OS functionality to include post-pc devices. We propose a novel programmatic solution to the problem of maintaining high data availability while attaining eventual consistency [16] in the presence of mobility and disconnected operations, device and network failures, and limited device capabilities. We achieve this by using a combination of a novel proxy architecture, a split request-reply queue based on soft-state principles, and a two-...
