Method for linking several communication busses using wireless links

Method for linking a first and a second communication bus through a wireless link, comprising a first portal connected to the first bus and a second portal connected to the second bus, said first and second portal communicating over a wireless connection, said method comprising the steps of:

• associating the two portals to the wireless network, wherein after association of the two portals, forcing at least one of the two portals to be the root node on its local bus;
• exchanging, between the two portals of self identification packets of nodes connected to their respective local busses, including the self identification packets of the portals themselves;
• —generating a reset on each bus;
• carrying out a self identification procedure on each bus, where each portal generates self identification packets for itself and for nodes of the respective remote bus, using the self identification packets received following the association step;
• and —having each portal determine, prior to exchanging self identification packets, whether the network topology which would result from linking the two busses would be valid or not, and in the negative, to abort the linking process.
