Abstract: 

We propose an easy-to-decode network coding scheme to offer reliable wireless broadcasting. Our encoding algorithm, based on user feedback, generates encoding vectors that are sparse enough to make the decoding process at the receiver much easier than that of the random linear network coding (RLNC) scheme. Simulations show that the worst-case delay performance of our scheme with a small finite field size is comparable to that of the RLNC scheme with a large finite field size while the average required number of operations in decoding of our scheme is less than that of the RLNC scheme.
