Query: LT Codes Combined with Network Coding for Multihop Powerline Smart Grid
  Networks   This paper describes a novel approach for combining Luby Transform (LT) codes
and Network Coding (NC) in the context of PowerLine Communications (PLC) smart
grid networks. Multihop transmissions of LT-encoded data on PLC networks are
considered and algorithms to combine data at relay nodes are proposed. Without
the need to decode and then re-encode the total received data stream, the relay
nodes can forward the received data stream while adding at the same time their
own data. Simulation results are provided confirming the good performance of
the proposed algorithms.
