Abstract:
1. A power line communication (PLC) system, comprising: a source node; a plurality of intermediate nodes; and a destination node, wherein each of the source node, the plurality of intermediate nodes and the destination node comprise a PLC interface including: wherein the routing modules of the source node, one or more of the intermediate nodes, and the destination node establish a route from the source node to the destination node via one or more selected ones of the plurality of intermediate nodes, wherein the route is selected using a route cost that is calculated based on link costs of a plurality of hops in the route from the source node to the destination node, wherein the link costs are based on forward link costs and reverse link costs, wherein when the destination node receives a route request packet, including a route cost, from one of the intermediate nodes corresponding to a neighbor node of the destination node, the destination node waits a predetermined period to receive one or more additional route request packets, wherein, after waiting the predetermined period, the destination node identifies a selected one of (i) the route request packet and (ii) the one or more additional route request packets having a lowest route cost, and wherein the destination node transmits a unicast route reply packet to the source node identifying the selected route.
