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.

9. The method of claim 8 , wherein obtaining the identification of the additional passenger-consumable content includes:
receiving a broadcasted transmission from the additional wireless device, the broadcasted transmission including the identification of the additional passenger-consumable content; or
receiving, from the additional wireless device, the identification of the additional passenger-consumable content in response to a request for respective identifications of any passenger-consumable content stored at the additional wireless device, the request transmitted from the lead wireless device to the additional wireless device.
10. The method of claim 1 , further comprising:
receiving, at the lead wireless device, a request of a first wireless device included the network for particular passenger-consumable content; and
in response to the received request,
obtaining, by the lead wireless device, the particular passenger-consumable content from a memory of the lead wireless device, from a second wireless device included in network, from another network on-board the vehicle, or from the on-board server, and
providing, by the lead wireless device, the obtained particular passenger-consumable content to the first wireless device.
11. The method of claim 10 ,
further comprising storing, at the lead wireless device, respective indications of at least one of: respective content stored at each wireless device included in the network, respective content stored at the another network, or respective content stored at the on-board server; and
