Cluster approach for network routing in hierarchical systems

This paper considers routing in a hierarchical space based on the principle of greedy forwarding. In order to avoid overloading the hierarchical tree, we suggested to take into account horizontal communication channels based on the cluster principle. We introduced notion of a cluster and the metric for describing the level of the intercluster transition. The modernised method of greedy forwarding involves the transfer of data with a deviation from the main hierarchical tree.
