This article introduces the knowledge of "what are the open source operating systems of the Internet of things". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Ubuntu Core

Because Ubuntu is a popular Linux distribution, Ubuntu Core IoT products have also become very popular. Ubuntu Core is a secure, lightweight operating system for the Internet of things, and is designed with the concept of "security first". According to official documentation, the entire system has been redesigned to focus on security from the first launch.

Ubuntu Core has tamper-proof function. Because applications may come from different sources, they only have privileges on their own data. This is done so that an improperly designed application does not make the entire system vulnerable. Ubuntu Core is built for business, which means that developers can focus directly on the application at hand, while other requirements are supported by the default operating system.

Another important feature of Ubuntu Core is the availability of the secure App Store, as well as an off-the-shelf software ecosystem, making it easier to use Ubuntu Core.

RIOT

RIOT is a user-friendly operating system for the Internet of things. RIOT supports many low-power IoT devices, and it also supports various microcontroller architectures.

It is developer-friendly: it supports standard environments and tools, so developers do not have to go through a steep learning process. Support for standard programming languages, such as C or C +. There is very little hardware-related code. Developers can write code once and then run their code on 8-bit, 16-bit, and 32-bit platforms.

RIOT is resource-friendly: one of the important features of RIOT is its ability to support light equipment. It can achieve greater energy consumption. It supports multithreading with little thread overhead.

RIOT is Internet of things friendly: the common system support provided by RIOT makes it a very important choice for the Internet of things. It supports CoAP,CBOR, high resolution and long-term timer.

Contiki

Contiki is an important operating system of the Internet of things. It helps connect lightweight, low-cost and low-power devices to the Internet. The main reasons for choosing Contiki OS are as follows.

Internet standards: in addition to the low-power 6 lowpanline RPL and CoAP standards, the Contiki operating system also supports IPv6 and IPv4 standards.

Support for a variety of hardware: Contiki can run on a variety of low-power devices, which are easily available online.

Large community support: one of the important advantages of using Contiki is that you can have an active developer community. Therefore, when you have to solve some technical problems, these community members will make the problem-solving process simple and effective.

The main functions of Contiki are as follows:

Memory allocation: even small systems with only a few thousand bytes of memory can use Contiki. Its storage efficiency is an important function.

Complete IP network: Contiki OS provides a complete IP network stack. This includes major standard protocols, such as UDP,TCP,HTTP,6lowpan,RPL,CoAP.

Power: the ability to assess power requirements and use them in a quality and minimal manner is an important feature of Contiki.

Cooja network simulator makes the process of software development and debugging easier.

The availability of the Coffee Flash file system and Contiki Shell makes file processing and command execution easier and more efficient.

TinyOS

TinyOS is an open source operating system designed for low-power wireless devices. It has a dynamic user community, and its users are all over academia and industry. The popularity of TinyOS is understandable from the fact that TinyOS has been downloaded more than 35000 times a year. TinyOS is very effective in a variety of scenarios, such as sensor networks, intelligent buildings, smart meters and so on.

Zephyr

Zephyr is a real-time OS that supports multiple architectures and is optimized for resource-constrained environments. Security is also important in Zephyr design. The main functions of Zephyr are listed below:

More than 150 boards are supported.

Complete flexibility and freedom of choice.

Can handle small Internet of things devices.

You can develop products with built-in security features.
