OpenThread

OpenThread is an open-source implementation of the Thread networking protocol developed by Google. It supports all key features of the Thread specification — including networking layers such as IPv6, 6LoWPAN and LR-WPAN — as well as mesh network capabilities that allow a device to function as both a node and a border router. OpenThread runs on a wide range of hardware platforms, leveraging a flexible abstraction layer and integration hooks that enable vendors to incorporate their own radio and cryptographic capabilities. This mature protocol is widely used in commercial products and, in our experience, has proven reliable for building diverse IoT solutions — from battery-operated, low-power devices to large-scale mesh sensor networks.
