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: In one embodiment, a device obtains location data indicative of a location of a mobile system relative to a base station of a wireless network. The device predicts, based on the location data, a drop in received signal strength indicator as the mobile system approaches the base station. The device determines, based on the drop in received signal strength indicator or throughput that will occur as the mobile system approaches the base station. The device prevents the mobile system from communicating with the base station during the ban.

Abstract: In one embodiment, a device identifies a plurality of access points of a wireless network. The device also identifies a plurality of mobile nodes of a mobile system. The device establishes a first label-switched path in the wireless network that comprises a wireless link between a first mobile node in the plurality of mobile nodes and a first access point in the plurality of access points. The device establishes a second label-switched path in the wireless network that comprises a wireless link between a second mobile node of the mobile system and a second access point in the plurality of access points.

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 mobile system receives a group identifier for wireless access points associated with a pathway via which the mobile system is to travel. The mobile system receives, during travel of the mobile system along the pathway, beacons from a plurality of wireless access points. Each of the plurality of wireless access points indicates its group identifier in its beacon. The mobile system selects, based on the beacons, a particular access point from among the plurality of wireless access points for roaming, in part by giving preference to any access points in the plurality of wireless access points having a group identifier that matches the group identifier associated with the pathway. The mobile system wirelessly roams to the particular access point.

Abstract: In one embodiment, a device in a wireless network selects a transmission rate for one or more packets to be sent, based on a received signal strength indicator value. The device makes a determination that the one or more packets should be compressed, based on the transmission rate selected by the device. The device applies, based on the determination, stateless offline dictionary compression to the one or more packets, to form a compressed stream of one or more packets. The device sends the compressed stream via the wireless network and using the transmission rate selected by the device.
