Mobile Sensor Approach to Location-Based Services

Moving object database is the core technology for location-based services (LBS), permitting users to pose spatial queries about the environment around them. We introduce a sensor-based LBS approach that is more economical and scalable for large-scale deployments supporting a large user community. We discuss this framework in the context of k-nearest-neighbor queries. We present simulation results and efficiency analysis to show the effectiveness of the proposed technique.
