summary

Paper claims MOSAIC replaces fragile hop-by-hop cellular sessions with SIM-based one-time tokens that let satellites locally authorize pay-as-you-go 4G/5G access, removing dependence on remote mobile operators. Prototype runs on a commodity 3GPP NTN protocol stack and is evaluated with real LEO satellite traces, showing token consumption adds low latency, eliminates signaling storms, and yields 100% serviceable area for users while enabling multi-operator tenancy and incremental deployment. Results validate viability and attack‑resilience in realistic settings.
