| 1. A method for scalable status change detection in a network of nodes, comprising the steps of:
determining reference positions in a virtual map environment;
determining node coordinate positions based on the reference positions in the virtual map environment;
clustering nodes based on the positions in the virtual map environment;
representing a cluster of nodes with a leader node where changes in a status of the leader node implies a status change in
the nodes of the cluster and wherein the changes in the status being monitored include delay changes, distance changes, security,
packet loss rate and/or activity changes; and
monitoring the leader node for status changes at a plurality of different cluster levels to provide scalable monitoring of
a network.
