Modeling and Querying Mobile Objects in Location-based Services

A location-based service delivers geo-related information and geo-processing services to a mobile/stationary user in accordance with their current location and preferences, or the location of stationary/mobile objects of their interest. Such services, like automatic vehicle location, fleet management, tourist services, transport management, traffic control and digital battlefield, are all based on mobile objects and management of their continuously changing locations. Thus modeling and the representation of mobile objects are fundamentally important in these applications. The goal of the work presented in this paper is to provide a mobile object data model for representing and querying mobile objects, with particular emphasis on those with point geometry, moving on a transport infrastructure that are pervasive in the location-based services. The mobile object data model extends widely accepted OGC Simple Feature model, also adopted by ISO TC 211. The implementation of the mobile object data model represents the foundation of the mSTOMM component framework, intended for development of the location-based services that deal with tracking and management of mobile objects. As such, it is suitable for integration in any OGC compliant GIS platform or a DBMS, enabling them in the mobile object domain.
