V2XFabric: 分布式侧行网状网与动态自组网互联拓扑体系

V2XFabric 落地车规级地理寻址路由 (GeoNetworking) 与多跳转发算法，将感知视野扩展至单个车辆视距射频极限范围之外。

通过智能多跳中继消除通信盲区

当高大卡车或城市建筑遮挡直线视距时，单跳 V2X 会失效。V2XFabric 依据 3GPP Release 17 的 UE 对 UE 规范，通过中间车辆作为透明中继来路由安全数据包。

Core Engineering Areas

Multi-Hop Sidelink Relay Protocols — Selecting optimal relay vehicles based on link quality, battery state, and geographic trajectory.
Ad-Hoc Mesh Routing — Preventing broadcast storms while ensuring emergency notifications propagate 2 kilometers upstream.
Multipath Traffic Distribution — Aggregating throughput and achieving 99.999% availability via redundant spatial paths.
