Claim of US Patent No. 10,356,843

1. A distributed method for selecting appropriate transmission configurations in a mobile ad hoc frequency division duplexing (FDD) mesh network, the method comprising:receiving, at a first node, one or more transmission parameters from at least one neighboring node, at least one of the transmission parameters including an indication of the first node's current, first transmission configuration, including an indication of a transmitting band first frequency and a receiving band second frequency wherein the first node performs single-hop bidirectional communication with one or more nodes having a second transmission configuration, wherein the second transmission configuration is an opposite transmission configuration including a transmitting frequency that is the second frequency and a receiving frequency that is the first frequency,
informing the first node about how it is being viewed by other nodes in the network; receiving, at the first node, one or more network parameters from at least one neighboring node, wherein the network parameters include connection information describing the first node's current network connection to the at least one neighboring node;
based on the received transmission parameters and the received network parameters, calculating, for at least the first node in the mobile ad hoc FDD mesh network, a change factor which indicates the desirability of changing transmission configuration, including changing the current transmission configuration to the opposite, second transmission configuration;
accessing the calculated change factor to determine whether the transmission configuration of the fist node is to be changed;
and upon determining that the change factor indicates that the transmission configuration of the first node should be changed, changing the transmission configuration of the first node from the first current transmission configuration to the second, transmission configuration causing the first node to perform single-hop bidirectional communication with one or more different nodes than the first node previously communicated with in single-hop bidirectional communication and preventing the first node from performing single-hop bidirectional communication with the one or more nodes having a second transmission configuration that the first node previously communicated with.
