Simulation Analysis on 5G-TSN Scheduling Algorithms based on OMNeT++.

The 5th Generation mobile system was featured as ultra-reliable and low-latency communications, which could support applications for industrial verticals. However, as to industrial control scenarios, it was necessary to ensure the deterministic data transmission. Therefore, 5G Rel.16 proposed Time-Sensitive Network technology integrating with the cellular mobile system to enhance the deterministic transmission capability of 5G networks. In the cooperation architecture of 5G and Time-Sensitive Network, the 5G system should enhance the capabilities of both the core network and access network to fulfill the cross-network transmission of time-sensitive services. As to the demands of cross 5G and TSN transmission, this paper built simulation environments for 5G-TSN cross-network transmission based on OMNeT++, which was aiming to verify the performance on latency, and throughputs of common-used scheduling algorithms of 5G systems such as proportional fairness, maximum C/I, and earliest deadline first in multi-service scenarios, as well as to verify adaption ability of scheduling to time-sensitive services in 5G system. The simulation results demonstrate that the proportional fairness algorithm can guarantee both the time delay performance of time-sensitive services and the system throughputs, and it becomes a potential scheduling algorithm for 5G-TSN cooperative transmission.
