An algorithm for joint optimization of dynamic routing and scheduling in time-sensitive networking
Published 2023-12-01“…Time-sensitive networking (TSN) is a set of protocols developed by the IEEE TSN task group, aiming at achieving deterministic communications over Ethernet.As the implementation method of TSN traffic scheduling is not specified in the protocols, the routing and scheduling algorithm for TSN remains an open issue.The joint optimization problem of routing and scheduling in TSN for industrial applications was modeled, and then an online heuristic algorithm was proposed to deliver the routing and scheduling solution for dynamic traffics.The routing path was determined by optimizing both the transmission delay and network load factors, and the scheduling time was quickly conducted by twice clipping operations.Finally, a simulated TSN testbed was developed with NeSTiNg framework based on OMNeT.The simulation results show that the execution time of the proposed algorithm outperforms the baseline algorithms even with large scale of network size and network traffics.It shows that the proposed algorithm guarantees the real-time performance even in dynamically changing networks.…”

Research on scheduled WLAN MAC protocol with failure retries on RoF-DAS architecture
Published 2020-03-01“…Aim to reduce control frames consumption and improve the delay performance,a scheduled gated-service polling access (SGPA) mechanism was proposed,in which the total data packets in the buffer at the polling instant were aggregated into a data set,that was transmitted and acknowledged uniformly.Then,an inner-arrival gated-service polling (IAGP) model was proposed to analyze the quantitative relationship between failure retry mechanism and network access performance of the wireless local area network (WLAN) in RoF-DAS.The failure retry mechanism were modeled as the arrival and service process of inner customers in IAGP.Using the Markov chain and generating function method,the closed-form expressions for the quantitative relationship between delay performance and retrial parameters,such as retry times,and the probability of retransmission,were achieved.The simulation results show that the proposed SGPA can achieve a lower delay than IEEE 802.11,and the theoretical performance evaluation calculated by IAGP are identical with the simulation results,which provides an effective evaluation mechanism for the access performance in RoF-DAS WLAN,with inperfect channel and failure retry mechanism.…”
