The advancement of embedded systems into the Internet of Things begins with some basic concepts. First of all, embedded systems are those physical devices that have electronics embedded inside them.
Henceforth, these electronics are present to monitor their operations efficiently. Nonetheless, usually monitors one or more microcontrollers among other components. Examples of embedded systems range from a digital weighing scale to a mobile phone.
Yet, the Internet of Things is a system of physical objects termed as things. IoT objects connect over the internet in order to establish a network. Examples of IoT are lamps, door locks, fridges, etc.
So, any computer which can connect to a network inevitably possesses a controller circuit. This circuit usually comes up in the form of a small chip, called an IC.
It can be a Wi-Fi chip, ZigBee, Z-wave, Ethernet, GSM, or any other type of network controller. But then, in essence, the connection to a network has been made conceivable by electronics within it.
By definition, then, an embedded system is any network that has connected devices. These devices were generally computers until a few years ago.
Yet then we see them evolving into all shapes and sizes, i.e., a smart bulb, a coffee maker, and a speaker. Consequently, we widely call them an evolution and are known collectively as the Internet of Things (IoT).
Advancement of Embedded Systems
If we understand the advancement of embedded systems, we will get better insights. Primarily, the embedded systems were impartial or standalone devices. They were running assembly or bare metal C code.
As the technology advanced, the embedded systems are becoming proficient in running operating systems. They can also connect OS to wired or wireless networks.
However, with the evolution of the internet, the usage of internet-based services has become very handy. So, people are getting more and advance information at their fingertips.
Supporting Processors and Networks in Advancement of Embedded Systems
On the one hand, the embedded technology evolved from 8-bit to 16-bit, 32-bit, and now 64-bit processor. These processors are supporting multi-core design and function at a gigahertz clock.
Also, they provide backup gigabytes of memory, integrating peripherals, and capable OS. Then again establishes Wi-Fi, gigabit networks, 4G-internet networks, and 4G-smartphones networks.
Embedded Systems Evolution to Internet of things
Embedded devices use wireless or wired networks to accommodate all forms of network communication. With this, the large pieces of embedded devices are easier to handle and monitor.
It has been made possible to remotely track and manage the embedded devices.
Internet access has been brought to the next level by smartphones. Mobile applications have helped users link to the internet at all times.
Also, to use internet-based services such as bill paying, e-commerce, social networking, video chat, etc. Embedded systems have increasingly become smarter, more integrated, and more user-friendly.
In the advancement of embedded systems, it was possible to run data analytics. Even more, ES able to link to the cloud and push the data. With the blessings of ES, it is conceivable to have a mobile app for monitoring and controlling the systems.
At this stage, people started schmoozing about the Internet of Things, Smart homes, Smart building, and Smart city, etc.
Internet of Things Momentum and Evolution
Even though all of these terminologies look dissimilar, however, they are associated somewhere in the context. We just need to join these dots to get the universal view.
Thousands of embedded systems have engendered massive quantities of data. Data can take from devices, regulators, surveillance cameras, video recorders, and sensors etc. This information is essentially gathered to analyze data.
Then analyzed data has used to produce a comprehensive information sense. Also, this data will use to cognize the behavior of the system. This data is even purifying and processing to apprehend consumer behavior.
The advancement of the Internet to 3G and 4G networks as well as their affordability, open roads for the Internet of Things. Society started chatting about linking and everything to the internet.
It can be your washing machine, a freezer, and a home robotics panel. The notion of associated things started evolving. So, IoT taking place and gaining momentum.
Consequently, chip originators came out with chips also with tons of sensor assimilation for IoT applications. Numerous companies started functioning along with IoT infrastructure, i.e., gateways, and cloud structure.
So, formerly embedded systems became impartial, they evolved into the Internet of Things. Say, in your house, you have a TV, a washing machine, a fridge, a camera, and a panel.
All these things can turn into the Internet of Things and connected to the Internet. Several protocols support the IoT gateways to communicate to these items and collect the data.
In general, this information pushes the cloud and web where processed data is present. The mobile app tracks the IoT systems as well as manage them.
All your embedded systems are present in this complete sequence. It might be a sensor, it might be a monitor, it might be a screen, and it might be a gateway.
So, there is far more in the IoT network than standalone embedded systems. In the advancement of embedded systems, it has embedded systems in stuff or edge applications. It has an IoT gateway, cloud access, data analytics, remote monitoring, and control mobile apps. IoT has given a different dimension to the embedded systems.
