Abstract
A wireless mesh network has a plurality of nodes. One of the nodes, referred to as a “topology building node,” is configured to discover a topology of the network. In this regard, a multicast topology message is transmitted via at least one node of the network. Each node that receive such message transmits a topology multicast reply to the topology building node which adds the transmitting node to the topology if the transmitting node is not already identified by the topology. Upon adding a node to the topology, the topology building node transmits a topology multicast command to the added node thereby causing such node to transmit a multicast topology message. Accordingly, the topology eventually receives a topology multicast reply from each node of the network allowing such node to build a complete topology of the network.
