Mobile computing introduces a new form of distributed computation in which communication is most often intermittent, low-bandwidth, or expensive, thus providing only weak connectivity. In this paper, we present a replication schema tailored for such environments, that seeks to adapt consistency guarantees to networking conditions. Bounded inconsistency is deened by allowing controlled deviation among copies located at weakly connected sites. The database interface is extended with weak… CONTINUE READING
