Geofence retrieval prioritization

A computer system, comprising:

• a processor;
• a memory device coupled to the processing unit;
• a measuring device or sensor;
• and
• a computer readable storage device coupled to the processor, wherein the storage device contains program code executable by the processing unit via the memory device to implement a method for prioritizing retrieval of geofences comprising the steps of:
• querying, by the processor, a list of geofences, wherein each geofence in the list of geofences comprises a location, a size defined by a boundary, a payload and an expiration time;
• receiving, by the processor, location data of the computer system;
• computing, by the processor, measurements from a measuring device or a sensor, quantifying movement of the computer system;
• estimating, by the processor, an amount of time for the computer system to travel to the boundary of each geofence in the list of geofences, as a function of the movement of the computer system, the location data and the expiration time of each geofence;
• retrieving, by the processor, each geofence from the list of geofences having an amount of time for the computer system to travel to the boundary of the geofence that is less than the expiration time of the geofence.

A computer program product comprising:

• one or more computer readable hardware storage devices having computer readable program code stored therein, said program code containing instructions executable by the one or more central processing units (CPU) of a computer system implement a method for prioritizing retrieval of geofences comprising the steps of:
• querying, by the CPU, a list of geofences, wherein each geofence in the list of geofences comprises a location, a size defined by a boundary, a payload and an expiration time;
• receiving, by the CPU, location data of the computer system;
• estimating, by the CPU, an amount of time for the computer system to travel to the boundary of each geofence in the list of geofences, as a function of movement of the computer system, the location data and the expiration time of each geofence;
• retrieving, by the CPU, each geofence from the list of geofences having an amount of time for the computer system to travel to the boundary of the geofence that is less than the expiration time of the geofence.
