1. A method for selecting operational channels in a communication network comprising a plurality of gathering nodes connected together by cable links and wireless links, the nodes connected together solely by wireless links forming a branch, the branches being connected together by cable links, said method comprising:
for each branch, selecting at least one operational channel, using said at least one selected operational channel for sending beacon frames and informing the other branches of the communication network of the selection thereof;
for each branch, determining whether there exists at least one selected operational channel in common between said branch and another branch;
identifying at least one group of branches wherein each branch has at least one selected operational channel in common with another branch in said group and wherein each branch sees from a radio-propagation point of view at least one other branch in said set;
for each group of branches identified, selecting at least one operational channel by realigning within the group the selections of at least one operational channel made by branch;
for each group of branches, applying the at least one operational channel selected by said group.
