Description
Summary:Undoubtedly, mobility remains a fundamental asset in wireless communications. Conversely, time-sensitive networking (TSN) represents a vital technology that enables determinism and low latency, fundamental for time-sensitive applications. In our study, we marry these two concepts by introducing a pioneering procedure that facilitates seamless roaming within a Wi-Fi-based Wireless Time-Sensitive Network (W-TSN). Through extensive real-world development and testing, we assess various techniques for optimizing handover moment selection and reducing handover delay. Our findings demonstrate that an integrated approach combining Received Signal Strength Indication (RSSI) and location-based online reduces the need for traditional channel scanning. This approach surpasses the offline and midpoint selection methods, excelling in identifying the optimal handover point and reducing handover delay to less than 20 milliseconds.
