Abstract: In one embodiment, a gateway to a Layer-3 network forms a first Layer-2 tunnel between the gateway and a first wireless access point (AP) that communicates wirelessly with a first mobile node of a mobile system (MS) via a first wireless connection. The gateway generates a mapping that associates an onboard device of the MS with the first AP and an identifier for the MS, based on traffic conveyed via the first Layer-2 tunnel and associated with the onboard device, the traffic comprising a header that indicates the identifier for the MS. The gateway receives, from a second AP, an indication that the MS is roaming from the first wireless connection to a second wireless connection, the indication including the identifier for the MS. The gateway updates the mapping to associate the onboard device of the MS with a second AP, based on the indication that the MS is roaming.

Abstract: In one embodiment, a mobile system scans wireless channels for any upcoming access points using a dedicated monitor radio of the mobile system. The mobile system identifies a particular wireless channel in use by an upcoming access point. The mobile system notifies a second radio of the mobile system of the particular wireless channel. The mobile system performs a handoff between a current access point and the upcoming access point in part by switching the second radio of the mobile system to the particular wireless channel of the upcoming access point.

Abstract: In one embodiment, a networking device receives packets of a traffic flow destined for a mobile system. The networking device sends a first flowlet of the traffic flow towards the mobile system via a first wireless access point. The networking device determines an idle time between the first flowlet and a second flowlet of the traffic flow. The networking device sends, based on the idle time, the second flowlet towards the mobile system via a second wireless access point.

Abstract: In one embodiment, a device identifies a path of travel of a mobile system. The device subdivides the path of travel into a plurality of zones. The device generates time-slotted channel hopping schedules for the plurality of zones, each time-slotted channel hopping schedule having an associated zone among the plurality of zones. The device causes the mobile system to communicate wirelessly with networking infrastructure located along the path of travel, in accordance with a particular one of the time-slotted channel hopping schedules while the mobile system is located in its associated zone.

Abstract: The present disclosure is directed to 3-D visualization of wireless signal propagation representing wireless signal strength and interference in 3-D space. The present technology can identify a plurality of access points (APs) in the 3-D space, determine a wireless signal strength for each of the plurality of APs, and determine an interference with the wireless signal strength of each of the plurality of APs, wherein the interference is caused by a neighboring AP of the plurality of APs in the 3-D space. The present technology can further present a 3-D visualization of a wireless signal propagation pattern representing the wireless signal strength from each of the plurality of APs in the 3-D space and the interference from the neighboring AP.
