Algorithm 2

EDEC algorithm for relay nodes.

(1) if every symbol in the received packet is intact then

(2) if (a predetermined number) packets received then

(3) Generate randomly, linearly combined packets using the received packets (network coding)

(4) Send out the network encoded packets

(5) end if

(6) else

(7) Mark the packet as corrupted and send it out

(8) end if
