Conditional-Coverage Contributor Selection for Regional Digital Twins Under Mobility

2026-09-28

AI Summary

This study addresses the challenge of coordinating contributor admission for regional digital twins in mobile scenarios over congested broadcast networks lacking fixed infrastructure. Modeling regional state as a public good, this work proposes a host coordination protocol that dynamically admits contributors based on timely non-redundant coverage gain and congestion pricing. To eliminate single-shot redundancy through set-level decision-making, the protocol incorporates a lightweight pre-transmission scoring mechanism using 13-byte beacon summaries. Experimental results demonstrate that, under equivalent network load, the proposed approach reduces the timely actionable coverage deficit from 5.6% to 1.4%, achieving a 26% performance improvement over random admission strategies.

Abstract

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.
