Data transmission method performing Luby transform (LT) coding in a broadcasting scheme

摘要

A data transmission method may include: dividing original data to be transmitted from a transmitting node to a plurality of receiving nodes into a plurality of sub groups having K (K being a natural number equal to or larger than 1) packets, performing Luby transform (LT) coding on the respective K packets in all of the plurality of sub groups to generate a plurality of transmission packets, and transmitting the plurality of transmission packets to the plurality of receiving nodes in a broadcast scheme.
