Some Foundational Problems in Mobile-Based Services

The substantial complexity of Mobile-Based Services (MBSes) comes from the need to support flexible policies and provide fault-tolerance while scaling to a large space size, client number and query/update density. Despite impressive progress in characterizing space-temporal indexing of moving objects, many problems remain unsolved, and the behavior of clients is still poorly understood. This paper argues that the authors must understand MBSes and any system supporting MBSes in terms of: intrinsic properties and design trade-offs of policy-based MBS system, independent of the specific back-end algorithm, properties that related to difficulties in scaling system requirements, and user's arbitrary behavior that causes specific faults in MBS System.
