Information Management in a Ubiquitous Global Postioning Environment

Recent developments in Global Positioning Systems (GPS) and personal locator technologies will enable environments in which (i) objects know their exact location as well as the locations of surrounding objects and (ii) objects are able to report their location and a profile back to regional servers. We envision a new environment where active GPSs are ubiquitously attached to every object in the environment. We term this environment the Ubiquitous Global Positioning Environment (UGPE, for short). Users in an UGPE environment will be able to subscribe to a variety of services. Services range from assisting the navigation of objects by continuously informing users of the surrounding obstacles/objects, to users forming groups of objects that are queried on a continuous basis. This vision paper highlights challenges and opportunities for database and information management research arising from this new environment. UGPE is characterized by a unique combination of ubiquity, large scale real-time spatia-temporal data, spatial and temporal fuzziness, and new types of queries. Understanding query processing and data management in UGPE is fundamental to the success of such environments and it provides a basis for using UGPE in novel applications.
