And for that, IoT app development companies and IoT engineers are pushing the boundaries of this very disruptive technology. Fortunately, there are lots of open-source resources available for IoT engineers to experiment and come up with unique products. So, if you are one of those IoT engineers who are on the hunt to discover goldmine, here is one. In this blog, I will list out top IoT OS, top IoT hardware platforms, top IoT software platforms, and top IoT protocols. 

Top IoT OS

Generally, in mobile phones, an OS works as a translator between hardware (touch screen, speakers, power button) and the software. It takes user command as the input from the hardware, processes it using software and gives relevant output. Same as a mobile OS, an IoT device should have OS which processes the data and manages functions. In the specific term, an IoT OS takes care of memory, size, power and processing capacity. In older versions of IoT devices, IoT OS doesn’t play a significant role. But since the latest IoT devices collect much information and have a lot of nodes, a control system (OS) is needed. 

Following are the top 5 most popular IoT OS.

Intel has been leading the IoT movement and probably among a few companies which have experienced the evolution of IoT. Intel had already released many boards a while ago. Those boards accommodated all-important IoT features.  But later, Intel had discontinued some of the boards and launched a few more revolutionary boards. Though Intel IoT hardware platforms have all the same features as other platforms, there is one area where no other platforms can beat Intel – processing power! Intel Edison Compute module is the most popular IoT hardware platform.

It is running on 512 KB programmable flash and 32 KB of RAM and supports dual-band operation. In order to develop an application based on real-time information, it is equipped with real-time clock capabilities. 

Top IoT software platforms 

Just because of the fact that an IoT project includes hardware as well as software development, IoT project has always been a tedious task. IoT engineers do not only need to take IoT hardware into account, but they are also required to write code to control the hardware product via a cloud system. To do so, IoT software plays a significant role. And to use the IoT software, you should have knowledge of some programming languages. 

Following are the top 3 IoT software.

Losant has two very unique features. One is real-time stream processing and another is batch processing. Because of these two features, an enterprise can perform complex analytics and offer a dynamic experience to users.     

Top IoT protocols 

An IoT device actively sends data to the server and mobile apps. At the same time, it also gets data from mobile apps and server. So, whenever there is data communication between two entities, we must follow a protocol which protects and ensures the optimal security to the data while it is being exchanged through the communication channel. 

Following are the top 3 IoT protocols. 

Constrained Application Protocol (CoAP)

CoAP is the web transfer protocol and it is generally used with constrained nodes and constrained networks. With this protocol, one can establish the connection between the server and client – the client can send a request to server and server can respond in HTTP. To reduce the space usage, it derives benefits from User Datagram protocol. Automation, mobiles and microcontrollers are the areas where CoAP is used widely. 

Advanced Message Queuing Protocol (AMQP)

AMQP is very useful for message-oriented middleware environment which is responsible for routing and queuing. It establishes the point to point connection and supports secure data exchange. Using AMQP, developers can establish the link between one message with another. Because of its security features, AMQP is widely used in the banking industry. This protocol tracks each and every message until the message is delivered to the user.  

MQTT (Message Queue Telemetry Transport) 

MQTT is the most preferred IoT protocol. It supports remote device monitoring, establishes the connection and collects data from many IoT devices. It runs on TCP and so, it can exchange message based on the event. One unique thing about MQTT is that it is the subscribe/publish protocol. Meaning, only a device gets a message from another device if a device is subscribed to another device. Since MQTT is the light-weight protocol, it is only used in devices which require less power and battery, I.e. car sensors, smartwatches and fire detectors. 


Developing an IoT product and software to control it is not as easy as pie. e-scooter app development is the best example of how difficult it is to actualize the IoT product like e-scooter and software like e-scooter app. An IoT engineer has to convert a physical object into a smart one by fitting in IoT controller or IoT hardware in it. Then he has to write the code for the user system which is used to interact with the IoT device. And lastly, to let users interact with IoT devices, he has to establish a connection between IoT device and user system (mobile app) using protocol. Throughout these processes, he does not have any other option than available hardware platforms, software platforms, and protocols.
