IoT Operating Systems

An operating system is any computer’s brain and nervous systems, such as laptops, smartphones, and servers. The operating system is responsible for controlling an application’s software and hardware by assigning all resources such as processing, memory, and storage. The operating system has both open-source and commercial versions.

IoT operating systems are created to perform well within the limits of small IoT devices. If there was no OS, each application would have to have its own user interface and codebase to handle the nitty-gritty of the underlying computer. In this article, you will learn the best IoT operating systems. But before discussing the best IoT operating system, you must know about the IoT operating system.

What is IoT Operating System?

IoT operating systems enable users to perform basic computer activities on an internet-connected device. IoT OSs run on IoT devices and connects to a larger network of devices. These operating systems offer computer-like capabilities by providing memory and data storage processing capability. These systems may run and process any program that is installed on the device. Operating systems for IoT devices communicate with IoT device management software.

There are various best IoT operating systems available today. Some of the best IoT operating systems are as follows:

1. TinyOS
2. Contiki
3. RIOT
4. Ubuntu Core
5. Fuchsia OS
6. Windows 10 IoT
7. Tizen
8. Android Things
9. OpenWrt
10. Mbed OS

TinyOS

TinyOS is a component-based open-source OS. TinyOS’s fundamental language is nesC, a version of the C programming language. It is designed for wireless sensor networks. TinyOS is very popular among developers because to its memory optimization capabilities. TinyOS includes a component that neutralizes some IoT system abstractions, such as sensing, packet transmission, routing, etc. TinyOS Alliance is the developer group for this IoT Operating System.

2. TinyOS is an embedded operating system that runs on all devices. TinyOS requires less memory to execute. If you wish to run this OS, you don’t require buying more memory devices.
3. TinyOS’ source code is relatively minimal. The code may be optimized to help run for any particular system. Devices run faster due to their reduced code, and the OS doesn’t overload the device.
4. TinyOS is a portable OS that may be used on several devices. If the devices are of the same nature, the coding doesn’t need to be altered.
5. TinyOS is made up of various modules. The modules have various functions, including tasks, microcontrollers, commands, hardware, events, and software. Each module performs its own function.

Disadvantages

1. Some modifications are required to allow communication among hardware and software. It is due to the low voltage constraint.
2. TinyOS programming is tough due to constraints such as memory limits, asynchronous behavior, and low voltage. The main downside of this operating system is the NesC programming language.
