Abstract: 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). For example, maintaining a repository with wireless meta-data in a way that location databases are maintained is not an appropriate solution. Both query complexity and availability/freshness/precision requirements for that data are different from the requirements for location data. This project examines the problem of implementing and maintaining a wireless interoperable infrastructure with a comprehensive metadata repository - a pervasive catalog system, for highly distributed and constantly changing mobile wireless environments. Advanced methods of data management in wireless networks are applied to provide efficient maintenance of the metadata in a pervasive catalog.
