NexusScout: An Advanced Location-Based Application on a Distributed, Open Mediation Platform

摘要

This demo shows several advanced use cases of location-based services and demonstrates how these use cases are facilitated by a mediation middleware for spatial information, the Nexus Platform. The scenario shows how a mobile user can access location-based information via so called Virtual Information Towers, register spatial events, send and receive geographical messages or find her friends by displaying other mobile users. The platform facilitates these functions by transparently combining spatial data from a dynamically changing set of data providers, tracking mobile objects and observing registered spatial events.
