Efficient wireless multicast retransmission techniques based on multiple coded packets

Abstract

This paper evaluates the performance of four algorithms for wireless network multicast transmission in a single cell. An efficient retransmission technique for multicast services based on network coding with a buffer is proposed and compared to other traditional schemes, such as the case with no retransmission, a simple retransmission and retransmission with multiple coded packets scheme. It is shown that the proposed algorithm outperforms other techniques and quality of the multicast transmission is improved.
