From Location Databases to Pervasive Catalog
One characteristic of the next generation wireless mobile environments is a high level of interoperability between mobile applications and services. This imposes significant demand on the knowledge maintained by the wireless network about itself (system meta-data). Maintaining a repository of wireless meta-data in a way that location databases are maintained is not sufficient to support adaptable application interoperability. The availability/freshness/precision requirements for the system meta-data are different from the requirements for location data and involve more complex monitoring queries. In this paper we examine the problem of implementing and maintaining a wireless interoperable infrastructure with a comprehensive meta-data repository — a pervasive catalog system. Our proposed pervasive catalog system utilizes advanced data management methods in wireless environment and is structured as a dynamic hierarchy of meta-repositories, consolidating meta-data at different levels...
