ROUTING MESSAGES BASED ON GEOLOCATION INFORMATION

摘要

Embodiments relate to method and computer program products for routing messages based on geolocation information. Aspects include receiving a message from a publisher, computing a geo-hash for the message based on a location associated with the message, and traversing a geo-hash tree associated with a subscriber to determine if the geo-hash of the message corresponds to a geo-hash grid in the geo-hash tree. Based on determining that the geo-hash of the message corresponds to an identified geo-hash grid in the geo-hash tree, a point in a polygon algorithm is performed to determine if the location associated with the message is inside an area of interest associated with the identified geo-hash grid. If the location associated with the message is inside the area of interest, the message is forwarded to the subscriber.
