Energy consumption of smartphones and IoT devices when using different versions of the HTTP protocol
🤖 AI Summary
Quantifying the end-to-end energy consumption differences among HTTP/1.1, HTTP/2, and HTTP/3 on resource-constrained mobile and IoT devices remains an open challenge, particularly across diverse network conditions and usage patterns.
Method: We conduct a systematic, controlled experimental study on real smartphones and IoT devices, covering machine-to-machine (M2M) communication and browser-like interaction scenarios under varied network conditions—including high packet loss—request sizes, and device models. Energy measurements leverage PowerMonitor hardware alongside low-level Android/iOS power APIs, complemented by cross-protocol traffic modeling.
Contribution/Results: This is the first empirical, end-to-end energy comparison of all three HTTP versions on actual mobile and IoT endpoints. Results show HTTP/3 reduces energy consumption by 12–19% over HTTP/2 under high packet loss; conversely, HTTP/1.1 outperforms both in small-request scenarios due to lower handshake overhead. These findings have directly informed protocol stack optimizations at two IoT vendors and provide evidence-based guidance for HTTP protocol selection in mobile and embedded systems.
