Table 12 Communication cost comparison between baseline and proposed MPC-Based Aggregation.
Scheme | Communication Topology | Compression Used | Communication Complexity | Per Round Communication (MB) | Reduction (%) |
|---|---|---|---|---|---|
Baseline FL (No MPC) | Centralized | No | O(N) | 80 MB | – |
Naive MPC (Fully Connected) | All-to-All | No | O(N2) | 340 MB | – |
Naive MPC + Quantization | All-to-All | Yes | O(N2) | 210 MB | 38% |
Proposed Efficient MPC (Ours) | Ring-Based | Yes | O(N) | 95 MB | 72% |
