1. A method, comprising:

  • receiving, by a first node in a network comprising a plurality of nodes, a data packet, the data packet identifying a destination node in the network to which the data packet is to be sent, each of the plurality of nodes comprising at least two communication interfaces, wherein the communication interfaces comprise at least one of a power line communication (“

    PLC”

    ) interface and a radio frequency (“

    RF”

    ) interface;

    selecting, by the first node, a particular transmission path from the first node to the destination node, based on a determination that the selected transmission path will introduce a least number of interferences compared to one or more other transmission paths, each transmission path comprising either a PLC interface option or an RF interface option for each of at least one node between the first node and the destination node;

    indicating, by the first node to each node in the selected transmission path, the particular interface option for that node in the particular transmission path;

    transmitting, by the first node, the data packet to the second node via the particular transmission path using one of the selected PLC interface or the selected RF interface;

    transmitting, by the second node, the data packet to a third node via the particular transmission path using one of the selected PLC interface or the selected RF interface and not the same communication interface as transmitted by the first node.
