Energy Consumption and Communicating Protocols
summary
Defines processing, wire and routing efficiency and measures MQTT DDS and Zenoh using throughput tests and wire counts. Zenoh implementation in Rust achieves 24 Gbps versus MQTT ~500 Mbps at 1 KB messages, hits a 32 KB MQTT throughput drop, and reaches a minimal frame overhead of five bytes (asymptotic three bytes) via batching and integer resource IDs. Zenoh reports 20x wire-efficient vs DDS and 95–99% reduced discovery traffic, yielding 1 year overhead examples 157 MB vs 1.8 GB and cost ~$1.2k vs $14k.
