In a wireless or hybrid mesh communication system, radio frequencies are managed by assigning an in-use frequency channel to each local family of nodes, distributing spare frequency channel(s) among the local families of nodes, and changing the in-use frequency channel of at least one selected local family of nodes to a new frequency channel selected among its spare frequency channel(s), if any, or among the spare frequency channel(s) of another local family of nodes if said at least one selected local family of nodes has no spare frequency channel(s), and/or as the in-use frequency channel of another local family of nodes if none of said local families of nodes has spare frequency channel(s).

MAC protocol selection is described. In a communication system, a MAC protocol is automatically selected from a set of MAC protocols based on a connectivity graph of at least part of the communication system.

Method of detour path determination for data packets re-routing in a mesh network comprising a plurality of N nodes, arranged according to a network topology, each node has a K-hops neighborhood knowledge of the network topology, with 1&#x2266;K&#x3c;N, primary paths are predefined for routing data packets within the mesh network. Detour paths are automatically discovered and set up while expending relatively few resources in terms of processing complexity, signaling and information spreading. The method is particularly advantageous when used in a wireless mesh network wherein the available bandwidth and the node resources and capabilities are much more limited than in wired networks.
