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.
