A way for error recovery is forward error correction (FEC), where a sender sends redundant information alongside the data bits, and a receiver gets the data bits and can correct conceivable errors using the redundant information. Since, in WSNs, packets are ordinarily broadcast over shared channel and forwarded over numerous hops, utilizing FEC is ideal sinbecause it can reduce the need to retransmit data packets, along these lines, diminishing the power consumed simultaneously.
In \cite{Ref10}, the authors have presented a basic successful model to accomplish high performance reliable multicast based on adaptive forward error correction (AFEC), which is over a wide range of redundancy levels. The sender selects the optimal redundancy level at a small amount of the first cost. Also, they have proposed two simple and proficient algorithms for choosing the repetition level depending on the network conditions. Their approach is independent of any reliable multicast protocol; it can be used with any dependable multicast protocol supporting negative acknowledgments (NACK) (or any other semantic to gather the information about lost packets). Subsequently, the approach is simple, effective and very versatile. The greatest advantage of the methodology in \cite{Ref10} is the performance boost, by off lining the FEC era. The plate overhead included is specifically relative to the scope of system misfortune.

Authors in \cite{Ref11} have discussed the issues of consolidating eradication based FEC with dependable multicast transport ARQ schemes. It has been demonstrated that a coordinated FEC/ARQ for reliable multicast transport can accomplish noteworthy productivity upgrades, particularly for uncorrelated packet loss. A case outline of integrateding this approach into a current ARQ reliable multicast convention was presented and performance tradeoffs were discussed.
