1. A method comprising:

  • determining a strength of received signals on communication links from neighbor nodes in a mesh network, the received signals including multiple different communication technologies, wherein the multiple different communication technologies include multiple different radio frequency (RF) communication technologies having different RF modulation schemes;

    selecting a subset of the communication links based in part on the strength of the received signals;

    exercising the subset of the communication links by sending data and receiving response data via each of the subset of the communication links;

    analyzing the response data;

    evaluating a link quality as a function of an available data rate of each of the subset of the communication links based in part on the analyzing;

    determining a figure of merit (FOM) based at least in part on a combination of the link quality and the available data rate for each link in the subset of the communication links;

    employing a routing protocol to select a communication link from the subset of the communication links for routing a data packet to a neighbor node based in part on the FOM associated with the selected communication link and an identified communications technology; and

    transmitting the data packet to the neighbor node using the identified communication technology and the available data rate of the selected communication link.
