First Claim
Patent Images
1. A method for determining an approximate location of a target node attached to a network comprising:
- determining communication latencies amongst a plurality of reference nodes;
measuring the communication latency between the target node and at least one of the reference nodes; and
approximating a geographic region within which the target node is located according to the communication latency between the target node and at least one of the reference nodes.

Abstract
A plurality of reference nodes that are attached to the network are correlated with geographic location. Communication latency between the reference nodes are used to approximate the location of a target node once the communication latency from one of the reference nodes to the target node is determined.
