Location-Aware Pub/Sub System: When Continuous Moving Queries Meet Dynamic Event Streams

Summary: Elaps is a location-aware pub/sub system for continuous moving queries over dynamic event streams from social media and commerce. Key ideas include impact regions to trigger safe-region updates, a cost model with incremental iGM/idGM safe-region construction, and BEQ-Tree for expressive spatial Boolean matching, achieving real-time, low-overhead dissemination.
