Abstract
A distributed tempero-spatial query service uses a plurality of service agents each having an assigned area of responsibility. The service agents are organized into a spatial hierarchy based upon each service agent's area of responsibility. The spatial hierarchy is distributed and hosted on each of the service agents. The spatial hierarchy enables matching of requests from subscribing agents with publishing agents based upon spatial attributes. The spatial hierarchy is dynamically maintained in a distributed manner on each of the service agents. The service agents can be arranged into a tree-based spatial hierarchy having a limited depth.
