针对移动性下区域数字孪生的贡献者选择问题，提出宿主协调协议，通过13字节信标摘要评分，将覆盖缺口从5.6%降至1.4%，比随机接纳降低26%。
AI 中文摘要
移动性下的区域数字孪生（DTs）必须在没有固定基础设施的拥塞广播网络上协调贡献者的接纳。每发送者冗余缓解无法做出这种集合级决策，因为只有宿主拥有区域范围的覆盖图。将区域状态视为公共物品，本文开发了一种宿主协调协议，接纳在周期截止时间内其及时、非冗余的覆盖增益超过拥塞价格的贡献者。一个13字节的信标摘要支持传输前评分。基于标准的仿真表明，在与ETSI冗余缓解相当的负载下，该协议将及时可操作的覆盖缺口从5.6%降至1.4%，在匹配的紧预算负载下，与随机接纳相比降低了26%。
英文摘要
Regional digital twins (DTs) under mobility must coordinate contributor admission over congested broadcast networks without fixed infrastructure. Per-sender redundancy mitigation cannot make this set-level decision because only the host has a region-wide coverage map. Treating regional state as a public good, this letter develops a host-coordinated protocol admitting contributors whose timely, non-redundant coverage gain exceeds a congestion price within a cycle deadline. A 13-byte beacon digest enables pre-transmission scoring. Standards-based simulation shows the protocol reduces the timely actionable coverage deficit from 5.6\% to 1.4\% at load comparable to ETSI redundancy mitigation and by 26\% versus random admission at matched tight-budget load.
