An Improved Retransmission Approacb Based on Opportunistic Network Coding in Multicast Networks
A novel opportunistic-network-coding-based retransmission approach was proposed.According to the feedback on packet loss from the receiving nodes
this novel approach can not only efficiently select a combination of lost packets through Hash lookup for packet retransmission
but also can ensure priority retransmission making up to a single combination retransmission packet which can maximize the number of receiving nodes for recovering their lost packets.Furthermore
the proposed approach fully exploits the coding opportunity based on neighborhood association
and allows the receiving nodes to recover their lost packets from multiple retransmission packets.The simulation results show that this novel approach can effectively reduce the number of retransmissions to improve the transmission efficiency with respect to the existing algorithms.
