To improve the quality of service (QoS) of delay-sensitive application, a High-functional Node (HN) network is studied. HNs can operate automatic-repeat-requests between adjacent HNs. Meanwhile, duplicating packets and transmitting them along with the original packets between adjacent HNs may more improve QoS of livestreaming. Then, the Sub Optimal Number of Duplicated Packets Determining Method is proposed. However, duplicating packets causes traffic congestion and increases queueing delay on HNs. Thus, we expand conventional method into finite bandwidth network with queueing delay. In this study, queueing delay is derived by queueing theory and approximated as a normal distribution. In numerical analysis, we confirm that proposed method gives almost optimum solution. Thus, we analyze characteristics of the proposed method. From the result, proposed method can satisfy livestreaming QoS with small duplicated packets. However, proposed method cannot improve QoS in a network with heavy congestion or on large bandwidth flow. |
