Abstract:
1. In a computing environment, a method comprising: determining a primary recipient; determining state data corresponding to data already received at the primary recipient based upon a previous transmission, wherein the state data is determined by an algorithm at a file-level granularity, wherein determining the state data comprises communicating with the primary recipient from an access point, and wherein the access point maintains a reception state table configured to track a current data state of each vehicle within range of the access point; receiving a second set of data at one other recipient; combining, using XOR operation, a first set of data intended for the primary recipient and the second set of data intended for the one other recipient, based upon the state data, into encoded data; transmitting the encoded data to the primary recipient; receiving an acknowledgement of receipt of the encoded data from the primary recipient, wherein only the primary recipient transmits acknowledgements of receipt; in response to a determination that the second set of data was not intended for the one other recipient, determining whether the second set of data can be used in a decoding process in conjunction with the first set of data previously received by the primary recipient; and in response to a determination that the set of data can be used in a decoding process in conjunction with another set of data previously received by the recipient, performing the decoding process.
