Moving Objects Information Management: The Database Challenge

Miniaturization of computing devices, and advances in wireless communication and sensor technology are some of the forces that are propagating computing from the stationary desktop to the mobile outdoors. Some important classes of new applications that will be enabled by this revolutionary development include location-based services, tourist services, mobile electronic commerce, and digital battlefield. Some existing application classes that will benefit from the development include transportation and air traffic control, weather forecasting, emergency response, mobile resource management, and mobile workforce. Location management, i.e. the management of transient location information, is an enabling technology for all these applications. Location management is also a fundamental component of other technologies such as fly-through visualization, context awareness, augmented reality, cellular communication, and dynamic resource discovery.In this paper we present our view of the important research issues in location management. These include modeling of location information, uncertainty management, spatio-temporal data access languages, indexing and scalability issues, data mining (including traffic and location prediction), location dissemination, privacy and security, location fusion and synchronization.
