The invention concerns a method of configuring the topology of a communication network comprising a plurality of nodes (i,j, . . . , N), the communication network being organized as a forest structure comprising trees and subtrees, wherein at least one node i maintains a periodic timer and an expiration of the timer of the node i triggers the steps of: searching, by the node i, a parent node; selecting, by the node i, a parent node using at least throughput and subtree size as selection criteria; and migrating the node i to the selected size as selection criteria; and migrating the node i to the selected parent node along with its subtree size. Preferably, the step of selecting a parent node by the node i comprises a sub-step of executing a function having as parameters respective subtree sizes of a node j before and after the migration of the node i to another node k.
