Abstract:
1. A network comprising: a plurality of network communication nodes, wherein each of the network communication nodes includes a communications link that provides communications with neighboring network communication nodes within the network and a controller coupled to the communications link; wherein the controller calculates path metrics including both a path remaining available bandwidth (PRAB) from the controller's node to at least one destination node within the network, and at least one secondary metric selected from an interference cost metric (ICM) for the controller's node based on the number of 1-hop neighbors in communication with the controller's node, a path stability metric (PSM) for each path to the destination node, and a path delay metric (PDM) for each of the available paths to the destination node; wherein the controller selects a desired path for data transmission via the communication link from the controller's node to the destination node based on the calculated path metric; and wherein controller calculates the PRAB based on an available time quantity and an effective retransmission bandwidth (ETB) calculation; and wherein a one-hop ETB at node (i), used when node (i) is the final destination, is given by: where R where R where R
