Abstract: Access points and a wireless client device, such as a workgroup bridge, are configured to optimize a roaming algorithm of the client device for a high-speed vehicle scenario, such as a high-speed train. A static/dynamic neighbor list is generated and used to improve scanning efficiency. An improved parent access point selection procedure, metrics, and thresholds are provided to optimize client roaming along the vehicle's path, e.g., the train track.
