Wi-NetX: Next Generation Wi-Fi 7 based Train Wireless Networks

The ongoing development of IEEE 802.11be introduces a plethora of advanced features, encompassing wider bandwidth, multi-link operation (MLO), and latency-sensitive operation. In light of this progress, this paper proposes Wi-NetX, an innovative train all-wireless network leveraging the capabilities of the next-generation wireless LAN. Designed to adeptly support mission-critical transmissions in intra-train communication scenarios, Wi-NetX incorporates priority-based link allocation, flexible service period time extension, delay-guaranteed slotted service period operation, and expedited priority-based channel contention. The efficacy and remarkable performance of Wi-NetX are meticulously validated through both numerical analysis and simulation.
