AN ARCHITECTURE FOR LOCATION-DEPENDENT SEMANTIC CACHE MANAGEMENT

摘要

Location-Dependent Information Services is an emerging class of application that allows new types of queries such as location-dependent queries and continuous queries. In these systems, data caching plays an important role in data management due to its ability to improve system performance and availability in case of disconnection. In mobile environment, cache management requires more than traditional solutions. This paper presents a new semantic cache scheme for location dependent systems based on spatial property. The proposed architecture is called as Location Dependent Semantic Cache Management -^sLDSCM. In addition, we examine location-dependent query processing issues and segment reorganization.
