1. A method of conveying a communication from a transmitting node to a disadvantaged node of a wireless communication network, said disadvantaged node being a node in the network that is subject to localized interference that is present within a jammed region, the method comprising:

  • for each of a plurality of candidate nodes in the network, collecting by the candidate node of node quality data of the candidate node, the node quality data including statistics on the communication performance of the candidate node and a measured local noise level of the candidate node;

    for each of the plurality of candidate nodes in the network, sharing by the candidate node of the node quality data of the candidate node with at least one other of the plurality of candidate nodes in the network;

    for each of the plurality of candidate nodes in the network, determining by the candidate node of a node quality of the candidate node using the node quality data of the candidate node and node quality data received from at least one other of the candidate nodes in the network;

    for each of the plurality of candidate nodes in the network, determining a quality level of the candidate node, said quality level being dependent at least in part on a communication reliability of the candidate node and a proximity of the candidate node to the disadvantaged node;

    according to the quality levels of the candidate nodes, designating a node from among the plurality of candidate nodes as a relay node; and

    relaying by the relay node of the communication between the transmitting node and the disadvantaged node.
