On-board self-healing network for delivery of vehicle passenger-consumable content
A self-healing network on-board a vehicle includes multiple wireless devices that are directly and communicatively interconnected via communications backbone(s). One of devices is collectively determined by the other devices to be a lead device of the network, and therefore establishes a wireless link (e.g., an only wireless link) communicatively connecting any of the self-healing network devices to other devices/servers on-board the vehicle and external to the network. Passenger-consumable content may be delivered between any device of the self-healing network and the other on-board, external devices via the lead wireless device, its established wireless link, and the communications backbone(s). Any wireless device of the self-healing network may serve as a hot spare for the lead wireless device, so that the self-healing network may automatically reconfigure to mitigate and recover from faults, e.g., by automatically forming multiple, mutually exclusive sub-self-healing networks, each of which has its own cooperatively selected lead wireless device.

routing, by the device based on the mapping, a requested portion of the passenger-consumable content stored in a first self-healing network to a requesting device included in a second self-healing network, the first self-healing network and the second self-healing network included in the plurality of self-healing networks.
2. The method of claim 1 , wherein the requested portion of the passenger-consumable content is a first requested portion, and the method further comprises routing, by the device, a second requested portion of the passenger-consumable content that is stored at the one or more servers to a respective requesting device included in one of the plurality of self-healing networks.

wherein routing the requested portion of the passenger-consumable content to the requesting device includes accessing the copy of the requested portion stored at the lead wireless device of the second self-healing network.
7. The method of claim 1 ,
further comprising updating, by the device, the mapping responsive to additional passenger-consumable content has been newly stored in one of the plurality of self-healing networks; and
routing, by the device, the additional passenger-consumable content to another requesting device based on the updated mapping.
8. A device for delivering content for consumption by passengers on-board a vehicle, the device disposed on-board the vehicle and the device comprising:
one or more memories storing a mapping of portions of distributively stored passenger-consumable content and respective on-board storage locations, the respective on-board storage locations including a plurality of self-healing networks on-board the vehicle, each self-healing network of the plurality of self-healing networks having a respective plurality of wireless devices storing a respective portion of the distributively stored passenger-consumable content, the respective plurality of wireless devices of the each self-healing network including a respective lead wireless device providing an only wireless link communicatively connecting any device of the each self-healing network to one or more servers on-board the vehicle, and the device included in the plurality of lead wireless devices; and
one or more processors executing computer-executable instructions stored on the one or more memories to thereby route, based on the mapping, a requested portion of the passenger-consumable content stored in a first self-healing network to a requesting device included in a second self-healing network, the first self-healing network and the second self-healing network included in the plurality of self-healing networks.
9. The device of claim 8 , wherein the requested portion of the passenger-consumable content is a first requested portion, and the one or more processors execute the computer-executable instructions to route a second requested portion of the passenger-consumable content that is stored at the one or more servers to a respective requesting device included in one of the plurality of self-healing networks.
10. The device of claim 8 , wherein the device is the lead wireless device of the first self-healing network.
11. The device of claim 8 , wherein the device is the lead wireless device of the second self-healing network.
12. The device of claim 8 , wherein the device is the lead wireless device of a third self-healing network.
13. The device of claim 11 , wherein:
the requested portion of the passenger-consumable content is stored at another device included in the first self-healing network;
the one or more processors execute the computer-executable instructions to thereby obtain a copy of the requested portion from the lead wireless device of the first self-healing network and store the copy of the requested portion at the lead wireless device of the second self-healing network; and
access the stored copy of the requested portion stored at the lead wireless device to route to the requesting device.
14. The device of claim 8 , wherein the one or more processors execute the computer-executable instructions to thereby:
update the mapping responsive to an indication that additional passenger-consumable content is newly stored in the plurality of self-healing networks; and
route requested portions of the passenger-consumable content to respective requesting devices based on the updated mapping.
15. A system for delivering content for consumption by passengers on-board a vehicle, the system comprising:
one or more servers disposed on-board the vehicle;
a plurality of self-healing networks disposed on-board the vehicle, each self-healing network of the plurality of self-healing networks having a respective lead wireless device providing an only wireless link communicatively connecting any device of the each self-healing network to the one or more servers; and
