RIOT OS (An Operating System for IoT)

Introduction The Internet of Things (IoT) is used with heterogeneous devices. They range from 8 bit to 32 bit microcontrollers from different manufacturers. Traditional Operating system (OS) or the conventional embedded OS may not suit the requirements that these tiny devices demand (low power, small in size and low memory foot print). RIOT Operating system is a free and open source arachtiecture which is friendly to IoT applications and proved to be a perfect OS for IoT Systems. It started in the year 2008 as an Operating system for Wireless Sensor nodes, later the OS is fine tuned for IOT systems. Features of RIOT The OS is actively developed and maintained. There are no new programming environments, C or C++ can be used directly with existing tools like gcc, gdb, etc. Less hardware dependent code Supports 8,16 ad 32 bit microcontroller platforms Energy efficieny is maintained less interrupt latency, so real time capability is ensured multi threading is e
