This research provides the initial detailed technical analysis and empirical performance evaluation of Matter, an open, IPv6-based connectivity standard aiming to unify smart home device interoperability. The study quantifies Matter's encapsulation overhead, latency, and energy consumption over Wi-Fi and Thread, comparing its characteristics to existing smart home protocols.
Key insights
- Matter exhibits substantial encapsulation overhead (166 bytes over Wi-Fi, 79 bytes over Thread) due to its comprehensive security and interoperability features, posing a trade-off for resource-constrained networks.
- Device processing on constrained endpoints is the primary contributor to latency, with sleepy devices further introducing delays up to their poll or beacon intervals.
- For battery-operated Thread devices, polling frequency dictates energy consumption at low poll periods, but longer poll and report periods can enable battery lifetimes approaching 10 years, making sleepy devices suitable for infrequent, unidirectional sensors.
