    IEEE 802.11 WLAN analytical model for M2M small data service by WANG Ya-hui, CHI Xue-fen

    Published 2011-01-01
    “…Machine to machine(M2M) communications had a huge potential market.Wireless local area network(WLAN) as the main complement for 3G networks would carry a lot of M2M services.Considering the characteristics of typical M2M small data service which was delay tolerant and retry patient,a large time-scale backoff algorithm was proposed in the network model of IEEE 802.11 DCF.MAC layer service time probability distribution was derived,and IPP/G/1/K discrete-time queuing model was established in order to analyze the QoS performance of M2M under unsaturated traffic condition and imperfect channel in the WLAN.Simulation results indicate that the proposed algorithm effectively enhances system throughput and reduces system blocking rate.…”

    Optimized scheduling mechanism based on IEEE 802.1Qch standard in time-sensitive networking by Hongrui NIE, Shaosheng LI, Yong LIU

    Published 2022-09-01
    “…To address the problem of complex gating planning for generic time-aware shaper (TAS), a traffic scheduling mechanism of adaptive queue buffer size and hardware time slot length was proposed with the help of IEEE 802.1Qch standard.Taking traffic and network characteristics into account, a mixed integer linear programming routing and scheduling model was formulated to maximize the number of time-sensitive flows mapped to the target network and then further improve the network scheduling capability by balancing the traffic carried by each scheduling time slot.Moreover, the impact of traffic and network features on queue buffer and hardware scheduling time slot was obtained through different scenarios.Simulation results show that the proposed method could successfully deploy thousands of time-sensitive flows for solving the scheduling problem in local area networks, and can improve the scheduling success rate by up to 28% compared with other algorithms with feasible execution time.…”
