The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

An upper bound on the achievable sum-rate is derived, based on which the existence of an optimal segment activation level is theoretically established, and the proposed HSS/A schemes outperform conventional full-segment aggregation.

C2weakest assumption

The upper bound derivation and optimality result rely on idealized channel models and interference assumptions typical for SWAN systems that may not capture real-world propagation effects or hardware imperfections.

C3one line summary

Derives an upper bound on sum-rate for uplink SWANs establishing an optimal segment activation level and shows proposed hybrid schemes outperform full-segment aggregation via numerical results.
