Abstract

This paper discusses the multimedia multicast application problem with allowable delay and high packet loss rate.It proposes a new reliable multicast protocol based on relay nodes mechanism(RMPRM).The RMPRM protocol focuses on allowable delay provides quality of service(QoS) for multimedia.Relay nodes are placed along the multicast tree.Data recovery is done between relay nodes.This paper proposes the methods that enable protocol relays to request retransmission immediately and reduce the number of duplicate packets.It compares the RMPRM with non-reliable multicast protocols.Simulation results show that the RMPRM has high delivery ratio and low end-to-end delay for packet transmission.
