Geocast-Based File Transfer

A method comprising:

• geocasting a plurality of geocast messages via single hop, tiered geocasting directly from a source in a tier to a node in a different tier using long range transmitters and a long range forwarding zone, wherein the geocast messages are associated with a plurality of chunks of a file;
• waiting a predetermined amount of time;
• if a request for a chunk of the plurality of chunks of a file is received prior to expiration of the predetermined amount of time:
• incorporating the requested chunk into a new geocast message;
• and
• geocasting the new geocast message.

A non-transitory computer readable storage medium comprising executable instructions that when executed by a processor cause the processor to effectuation operations comprising:

• receiving at least one geocast message via single hop, tiered geocasting directly from a source in a tier to a node in a different tier using long range transmitters and a long range forwarding zone, each geocast message of the at least one geocast message comprising a respective chunk of a plurality of chunks of data of a file, wherein at least one geocast message of the at least one geocast message comprises an indication of a total number of chunks in the plurality of chunks;
• determining if all chunks of the plurality of chunks have been received;
• and
• when it is determined that all chunks of the plurality of chunks have not been received, geocasting a geocast message comprising a request for a missing chunk.
