Abstract

Location-aware application ns need not only rapid location-related query, but also proactive spatial event service, both of which the traditional database system does not excel at. Aiming at the deficiencies of database system, we present a light-weighted proactive spatial service model for Smart Classroom: ASMod. This model adopts such new technologies as combined spatial index, refreshing-up & suspension-notification service process method and smart active update policy. Consequently it can not only proactively provide spatial event service, but also offer more efficient location-related query service than database system. Besides, it is facilely integrated into a multi-agent system, which makes it convenient to be applied into Smart Classroom.
