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