RIOT (operating system)
RIOT is a small operating system for networked, memory-constrained systems with a focus on low-power wireless Internet of Things devices. It is open-source software, released under the GNU Lesser General Public License.Background
It was initially developed by Freie Universität Berlin, Institut national de recherche en informatique et en automatique and the Hochschule für Angewandte Wissenschaften Hamburg. RIOT's kernel is mostly inherited from FireKernel, which was originally developed for sensor networks.Technical aspects
RIOT is based on a microkernel architecture. In contrast to other operating systems with similarly low memory use, RIOT allows application programming with the programming languages C and C++. An experimental Rust API is also available. It has full multithreading and real-time abilities. SSL/TLS is supported by popular libraries such as wolfSSL.
RIOT runs on 8-bit, 16-bit and 32-bit processors. A native port also enables RIOT to run as a Linux or macOS process, enabling use of standard development and debugging tools such as GNU Compiler Collection, GNU Debugger, Valgrind, Wireshark etc. RIOT is partly Portable Operating System Interface compliant.
RIOT provides multiple network stacks, including IPv6, 6LoWPAN, or Content centric networking and standard protocols such as RPL, User Datagram Protocol, Transmission Control Protocol, and CoAP.
