摘要
A system(s), method(s) and computer program product to optimize Luby Transform codes to facilitate a transmission of data over a communication network are disclosed. Demands from various sinks are received and a demand vector is calculated. Various sources are employed with LT codes to encode the data. A Generalized LT code (GLT) is generated for an objective function determined for a given demand vector irrespective of the LT codes employed at the sources. Morphing rules are designed by optimizing a degree distribution of the data and mapping LT codes to the generalized LT codes. The GLT is optimized by using a linear transformation to obtain optimal morphing rules. The LT codes are retargeted by re-encoding an LT encoded data to further obtain an LT re-encoded data. The LT re-encoded data is then transmitted by a relay device to plurality of sinks.
