Abstract
A method for data transmission includes: if correctly receiving one or more source data packets, a destination node selecting source data packets which have not been saved from the source data packets to save; if receiving one or more network coded data packets, the destination node decoding them, and if the decoding can be correctly conducted and source data packets can be obtained, the destination node selecting source data packets which have not been saved from obtained source data packets to save; if judging that the number of currently saved source data packets is greater than one, the destination node selecting and sending one saved source data to other destination nodes, or after conducting network coding according to part or all of saved source data packets to obtain one or more network coded data packets, the destination node selecting and sending one network coded data packet to other destination nodes.
