Found in the set of routing network comprising a concentrator, the smart meter and the virtual node. Each concentrator node as the source broadcasts a route request to the virtual destination node (the RREQ) packet. The intermediate node routing node list stored in the RREQ packet (NL) and stored in the node routing table (RT). Subsequently, each smart meter node may be selected from any node to the smart meter concentrator primary route and secondary route from the routing table.
