Abstract: Architecture that enables location based notifications (e.g., geo-fences) using standard polygons the capture of complex regions. As applied to geo-fencing, it extends geo-fencing beyond the mere representation of the virtual perimeter (fenced) area. More specifically, the architecture takes into consideration geographical and demographical features, such as the layout of the roads and streets, the types of available of transportation (e.g., car, bus, walk, biking, etc.), the traffic conditions, and the dynamic properties of a point of interest (POI) such as opening hours, total wait time, etc.
