IMPROVED PROXIMITY DETECTION METHOD

摘要

The invention relates to a method of determining a proximity between a root node (301) and a leaf node (303) in a network. The method comprises computing a link proximity value between any two mutually connected nodes in the network, at an initial node, sending a proximity computation request message containing a proximity counter to an intermediate node to which said initial node is connected, at an intermediate node (302) being connected to a first node and to a second node, upon receipt of the proximity computation request message containing a proximity counter from the first node, adding the computed link proximity value to the proximity counter and passing on the proximity computation request message to the second node, at a final node, upon receipt of the proximity computation request message, determining the proximity between the root node and the leaf node as the value indicated by the proximity counter.
