Abstract
A mesh network system includes an electronic control unit. The electronic control unit is configured to calculate a plurality of radio metric scores for a plurality of network interfaces for a first vehicle of a plurality of vehicles of a mesh network as a function of radio metrics in a current motion state of the first vehicle. The radio metrics indicate performance of the plurality of network interfaces in the current motion state of the first vehicle. The electronic control unit is further configured to select a desired network interface from the plurality of network interfaces comprising a desired radio metric score indicative of a desired performance in the current motion state.
