A Deterministic Scheme for Handover Traffic Based on Smart Identifier Network

In the process of industrial digital transformation, wireless communication technology has garnered widespread acclaim for its high flexibility within production systems and robust support for mobility. Integrating wireless technology and Time-Sensitive Networking (TSN) into the wireless side of industrial networks can address the urgent need for time-sensitive data transmission in wireless devices. Since mobile handovers are very frequent in wireless communication scenarios, it is important to ensure TSN traffic's deterministic transmission during handovers. However, existing IP network architectures have difficulty in supporting a seamless handover process, which may cause significant delay and jitter. To address this issue, we propose a deterministic handover framework based on Smart Identifier Network, which can maintain the cognition of traffic within the wired network domain and ensure deterministic transmission during the handover. Additionally, we propose an interval-based scheduling algorithm to rapidly calculate feasible scheduling for handover traffic. Experimental results validate the excellent performance of the proposed algorithm and the effectiveness of the proposed deterministic scheme for handover traffic.
