ABSTRACT:
A system and method for scalable status change detection in a network of nodes includes embedding node coordinate positions into a virtual map environment. A cluster of nodes are represented with a representative node to form a hierarchy of nodes and clusters where changes in a status of the representative node imply a status change in the nodes of the cluster. By selectively monitoring the representative nodes for the changes in status, the representative nodes create a capability for scalable monitoring of the network.
