operating system for IOT devices

December 23, 2020

what is IOT (internet of things) ?

The Internet of Things (IoT) describes the network of physical objects( things ) that are embedded with sensors, software, and other technologies for the purpose of connecting and exchanging data with other devices and systems over the internet. These devices range from ordinary household objects to sophisticated industrial tools.

Unlike traditional Desktops and laptops, IoT devices don’t always have powerful processers or large amount of memory.

what is OS ?

An operating system is a program that acts as an interface between the user and the computer hardware and controls the execution of all kinds of programs.

It governs the memory and processes of the computer and all its software and hardware. You can also communicate with your computer without understanding the language of your computer. A machine is useless without an operating system.

What Technologies Have Made IoT Possible?

Access to low-cost, low-power sensor technology : Affordable and reliable sensors are making IoT technology possible for more manufacturers.

Connectivity : A host of network protocols for the internet has made it easy to connect sensors to the cloud and to other “things” for efficient data transfer.

Cloud computing platforms : The increase in the availability of cloud platforms enables both businesses and consumers to access the infrastructure they need to scale up without actually having to manage it all.

Machine learning and analytics : With advances in machine learning and analytics, along with access to varied and vast amounts of data stored in the cloud, businesses can gather insights faster and more easily.

Conversational artificial intelligence (AI) : Advances in neural networks have brought natural-language processing (NLP) to IoT devices such as digital personal assistants Alexa, Cortana, Siri, etc.

selecting an IoT operating system

Depending on the specific need or restraints driving the development of your IoT edge device, there are several considerations that will drive the decision-making process. One of the first areas where device builders often start is their level of familiarity with the platform.

So now the questions arises

What level of reliability and long-term support is needed?

Devices with low price points tend to have shorter lifecycles, and so might not need to support feature updates or software upgrades years down the road if consumers frequently purchase new versions.

· Is the device a specialized system (e.g., point-of-sale systems, ATMs)?

Specialized systems typically perform a single important task and don’t require feature updates as often as other devices, but it does mean they often require a longer servicing option and need to be kept as stable and secure as possible. This is why it’s important to look at the servicing model offered with the OS.

There are multiple operating systems for IOT devices so now we will see best of them.

Best IoT Operating System

An operating system is the core program of IoT projects. Modern IoT operating system uses cloud computing technology to control IoT devices anywhere from the world. With a low memory footprint and higher efficiency, each operating system represented below can fulfill the user’s requirement.

1. Contiki

Contiki is an operating system for IoT that specifically targets small IoT devices with limited memory, power, bandwidth, and processing power. It uses a minimalist design while still packing the common tools of modern operating systems. It provides functionality for management of programs, processes, resources, memory, and communication.

2. Riot

Riot is one of the free open source IoT operating systems built for IoT services. RioT has a huge development community, and it was released under an unclonable GNU Lesser General Public License. For these two reasons, RioT is called Linux of the IoT world. Academics, hobbyists, and different companies put their contribution together to develop Riot Operating System.

3. Apache Mynewt

Similar to Riot, this IoT OS is built for tinny embedded IoT devices. This is a real-time operating system under Apache License 2.0 which provides a complete environment for developing, managing, and operations of IoT devices. With rich libraries, modular-based operating systems like Apache Mynewt can work for long times.

Conclusion

To the success of any IoT project, operating system selection is important. With a wide range of operators targeting the IoT space compared to other settings such as personal computers and telephones, the characteristics of IoT are important to understand. Surely due consideration must be given to ensuring the suitability of any specific OS to all IoT components. At present Linux dominates the IoT gateways OS market. For both open source and commercial systems prevalence, the final option is motivated by the degree of freedom of production and rapid time-to-market considerations. With IoT, there are a wide range of sensory applications, which previously had no OS, but which use small foot printing systems more and more. There are now a wide range of RTOSes that target IoT nodes and the many choices for hardware architectures differ in capability and suitability.
