Abstract

This paper proposes to adapt IEEE 802.1 Time Sensitive Networking (TSN) standards and EDCA to wired and wireless home networks as a combined QoS control for smart house networks. The authors conducted several experiments under different scenarios with IEEE 802.1TSN standards such as Credit Based Shaper (CBS), and Strict Priority Queuing (SPQ), and EDCA. The results showed TSN’s ability to guarantee a much better QoS control by keeping the latency below 0.2 milliseconds across all traffic except one, with baseline latencies where no QoS control was applied, reaching as far as four milliseconds. This difference was considered statistically significant upon performing a t-test between the registered latencies values (With QoS and Without QoS) and finding a p-value of 0.042 (<0.05). The case of the outlier traffic was examined as well. Furthermore, these results were held with the new setup with SPQ, keeping low latency results. However, when combined with EDCA, there was a decline in the performance even though EDCA showed better results for the wireless network registering the lowest latency overall (below 0.1 milliseconds). Thus, concluding TSN and EDCA efficacy for home networks and the conditions under which that can be maintained. Future work will focus on minimizing the impact of SPQ on the wireless network with the application of EDCA. This paper is the first article to offer a complete study on SPQ, CBS, and EDCA as QoS control methods, potentially solving a growing problem in modern smart homes and addressing the dual challenge of QoS in wired and wireless home networks.

Keywords: QoS, TSN, SPQ, CBS, EDCA, home networking.
