IEEE 802.11ax employs a paradigm shift from a distributed to a centralized coordination strategy with its new channel access mechanism called Orthogonal Frequency Division Multiple Access (OFDMA). Using OFDMA, the Access Point (AP) always has to win contention against its associated Stations (STA) before it can initiate a trigger-based transmission. However, contention-based, distributed channel access mechanisms are still supported in IEEE 802.11ax networks, interfering with any hard real-time communication. Multi-user Enhanced Distributed Channel Access (MU EDCA), introduced in IEEE 802.11ax, was designed to influence when to use the distributed or the centralized coordination strategy. It allows to shift the probability of STAs accessing the channel towards the AP, such that the AP can initiate an OFDMA-based transmission. OFDMA is a promising starting point for real-time transmissions in Wi-Fi, We propose a modification of MU EDCA that guarantees worst-case channel access times for the AP in networks which only consist of Wi-Fi 6 capable devices (e.g., in the 6-GHz band). Simulations result in a worst-case channel access delay for the AP of $55 mu s$ independent of the number of STAs.","PeriodicalId":345607,"journal":{"name":"2023 IEEE 19th International Conference on Factory Communication Systems (WFCS)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128972766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Originally developed for Ethernet-based audio-video applications using the User Datagram Protocol (UDP). TSN assume unidirectional flows from source (talked) to destination(listener) and it is most easily implemented using UDP in which packets are transmitted without an acknowledgment from the recipient. However, most existing industrial protocols are implemented using the reliable Transport Control Protocol (TCP) in which each transmission is explicitly acknowledged. In this work, a bandwidth efficient TSN schedule is developed to accommodate the TCP traffic flow between two synchronized robots collaboratively moving an object. We then demonstrate an IEEE 802.1Qbv TSN schedule over an IEEE 802.11 wireless medium that guarantees robot performance requirements are maintained while accommodating concurrent best-effort traffic flows. The process for schedule selection and experimental data collection is discussed, and TSN configuration parameter tuning and experimental results are provided.","PeriodicalId":345607,"journal":{"name":"2023 IEEE 19th International Conference on Factory Communication Systems (WFCS)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116822261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
