Abstract:
1. A method of configuring the topology of a communication network of mesh network type comprising a plurality of nodes (i,j, . . . , N), said communication network being organized as a forest structure comprising trees and subtrees, at least one node i maintaining a periodic timer and an expiration of said timer of said node i triggering the steps of: searching, by said node i, a parent node; selecting, by said node i, the parent node using at least throughput and subtree size as selection criteria; wherein an expiration of said timer of said node i also triggers the step of: migrating said node i to the selected parent node along with its subtree size and, the step of selecting the parent node by said node i is performed by using a routing metric referred to as the Expected Throughput ETP defined as:
