Data management in location-dependent information services

Location-dependent information services (LDISs) answer queries in accordance with the locations the queries are associated with (e.g., the locations from which the queries are issued. The emergence of LDISs is resulted from the convergence of high-speed wireless networks, personal portable devices, and locatining techniques. LDISs have a variety of promising applications, such as local information access (e.g., traffic reports, news, and navigation maps) and nearest neighbor queries (e.g., finding the nearest restaurant), and are expected to become an integral part of our daily life. This seminar will provide background and an overview of research on location-dependent information access in mobile and pervasive environments. In particular, it will discuss the following topic areas:
