Selection of inter-network communication

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to:

• identify, by a processor, content to be communicated to a first network;
• identify, by the processor, information associated with a probability that a first device of a second network will travel to the first network;
• and
• transfer, by the processor and based on the probability that the first device will travel to the first network, the content to the first device.

A system comprising a first processor, wherein the first processor is configured to perform a method for inter-network communications comprising:

• broadcasting, to devices of a first network over the first network, a request for information associated with histories of travel of the devices to a second network;
• receiving replies over the first network from a set of the devices, each reply including information associated with the replying devices' history of travel to the second network;
• identifying, based on the replies, a first subset of devices within the set of devices that have travelled to the second network;
• identifying, based on the replying devices' history of travel, a second subset of devices within the first subset of devices that have a sufficient probability of travelling to the second network within a target time period;
• and
• sending, to the second subset of devices, data addressed to the second network.
