Geocast-Based File Transfer
First Claim
1. A system comprising:
- a first apparatus; and
a second apparatus communicatively connected with the first apparatus, the second apparatus comprising;
a processor; and
memory coupled to the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising;
geocasting a plurality of geocast messages via single hop, tiered geocasting directly from a source in a tier to the first apparatus 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 the 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.

Abstract
Geocast-based file transfer may be implemented via use of a Geocast File Transfer (GFT) protocol. A sending device may parse a file into multiple chunks. Respective multiple geocast packets comprising the chunks may be geocast. The sending device may geocast all packets sequentially. Upon geocasting all packets, the sending device may wait a predetermined amount of time. During the period of time, any receiving device that did not receive a chunk of the file may geocast a request for the missing chunk. Receiving devices also may wait various respective amounts of time before geocasting requests. Other receiving devices that may have missed a chunk may hear that the chunk it missed is being requested. And that device need not make a request for the chunk. Rather, that device may wait for the sending device to retransmit a geocast packet that contains the missing chunk.

17. 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. - View Dependent Claims (18, 19, 20)
