DESCRIPTION:Fountain codes are a natural coding solution for broadcasting:
  in such a case\, they are a good alternative to ARQ\, especially when non
 e or little feedback can be used. But their versatile structure allows usi
 ng them as a protocol for many communication network topologies. The talk 
 explores the application of fountain codes to a single-hop multi-relay net
 work. Specifically\, in the considered system\, relays do not decode the i
 nformation\, but simply perform parity checks on symbols they have receive
 d from the source. This allows for uncoordinated\, low-complexity algorith
 ms at the intermediate nodes.  Thus\, the presented protocol\, whose analy
 sis and design are described in the talk\, represents a hybrid between fou
 ntain codes and network coding\, named distributed fountain codes\, whose 
 potential makes it a promising candidate for next-generation wireless LANs
