28 Jan 21
The Internet of Things has been one of the most adopted technologies in the 21st century.
How to develop an IoT app successfully is a question mobile app developers worldwide are thinking about!
Though the idea for an interconnected network of things has been around since the 1980s and 1990s, it wasn’t until 2010 that the concept began to take off.
And now, in 2021, it has become a reality, not just in enterprises and industries but also in our homes.
Just think about wearable devices, home automation, smart gardening, and personal assistants!
According to statistics, in the year 2015, we had around 15.4 billion interconnected devices, and by 2025 it is estimated to reach a whopping 75.4 billion!
As IoT devices are becoming widespread, the need to develop IoT apps is also on the rise.
In this blog, we will talk about everything related to IoT app development.
But before that, let’s answer some basic questions about what IoT is and what its uses are.
What is the Internet of Things (IoT)?
The Internet of Things is a network that connects devices in an environment to support data exchange between them.
IoT creates a scenario where real-world objects can communicate with each other without any need for human intervention.
Any guesses how every device is connected in an IoT network?
Through the internet, of course!
It is a promising technology that aims to revolutionize people’s lives by changing the way they carry out their everyday routines, be it at work, home, or during transit.
Controlling the intensity of light through mobile phones, changing the humidity and temperature of conference rooms depending on the number of people, having your home’s door open automatically when you reach in front of it- IoT powers all these.
With each passing day, IoT is growing, and so is IoT app development.
What are The Key Components of the Internet of Things?
Before we look at how to develop an IoT app, let’s get familiarized with the structure of an IoT system.
There are four main components in any IoT system. They are hardware, software, network, and Cloud.
All the physical systems in an IoT system come under hardware.
These can be sensors, servers, routing devices, etc.
Almost all IoT systems will have sensors. These sensors act as measurement devices and could be used to measure several things depending on its application.
Measuring temperature, pressure, light, humidity, speed are some of the standard applications.
Another popular hardware in the IoT system are wearable devices.
These are electronic devices worn on body parts like the head, feet, arms, etc.
Smartwatches and smart glasses are examples of wearable devices.
The desktop, tablet, or mobile phone used to control the sensing devices will also come under hardware.
Software is the component that takes care of device integration, data collection, and analysis.
It is the bridge between hardware and the central server. It helps in collecting data from devices.
It ensures that all the devices are integrated, can work in cooperation, and communicate properly.
They manage the various protocols and settings of each device in an IoT system to ensure a stable real-time connection.
Software is also responsible for real-time analytics of data input from the devices.
The data from devices are converted into information suitable for human understanding by the software.
The network is the binder in an IoT system.
It is the link that connects different components in an IoT system together.
The network ideally takes care of the data transmission from and to devices.
It is also responsible for arranging intertwisted data into a systematic format.
Cloud is the backbone of an IoT system.
It is the space where data is processed and stored. With Cloud, there is no need for any physical resources for data storage.
Considering the high data needs of an IoT system and the limitations of conventional storage technologies, Cloud storage is the most useful and viable option for an IoT system.
What Are the Top 7 Layers of the Internet of Things?
Now that we have become familiar with the components of an IoT system let us take a look at how an IoT system works.
How actually does the data travel from one end to the other?
There are seven key layers on which an IoT system operates.
What are these seven layers, and what are their functions? Read on.
The first layer of an IoT system consists of the things- that is, devices, sensors, controllers, etc. It is the boundary between real and digital.
It is in this layer that real parameters are taken as input and converted into digital forms.
2. Things to Gateways
This is the layer that connects layer 1 (Things) to layer 3 (Gateways).
To achieve the data transmission between these layers, it is necessary to follow specific communication protocols and network standards. This is the first network layer of an IoT system.
Protocols like Zigbee, Bluetooth are employed here.
The gateways collect data from layer 2 and transmit it to the backend system.
They can be routers or modems that enable data transmission from Things to the Internet. Some sensory devices come with built-in gateways.
4. Gateways to Internet
This is just like layer 2, but it supports data transmission from gateways to the internet.
But unlike layer 2, this network may range over a broader area to support transmission to farther locations.
Ethernet, WiFi, Satellite are the protocols that are used in this layer.
5. Data Ingestion and Analysis
Data from layer 4 is collected, stored, and converted into legible information in this layer.
The data is stored in Cloud and processed using advanced technologies like machine learning to convert from raw format to valuable information.
6. Internet to Users
The processed data from the Cloud reaches the users through this layer.
This is the final network layer in an IoT system. To access data from Cloud, it uses the same protocols as layer 4.
The final layer in an IoT system, this is where users get to see the information collected from the Things (layer 1).
People might access this information through smartphones, desktops, or custom IoT apps.
The information may be transmitted in various forms, like graphs, alerts, numbers, or charts. Whatever form it may take, it will be presented in such a way where users can grasp it easily, derive insights, and take actions accordingly.
How IoT is Changing Mobile App Development?
From a market share of 235 billion USD in 2017, IoT is expected to reach 520 billion USD in 2021.
With its extent of connectivity, amount of data involved, and the level of integration in people’s day-to-day lives, IoT app development demands a change in the usual approach to mobile app development.
Since IoT is a complex technology and various new IoT frameworks make their appearance in the industry, it demands the developers to acquire a specific skill set.
The extent of functionalities required of IoT apps, the accuracy of the information, and the need for excellent security practices make developing an IoT application rather complex.
It is influencing mobile app developers to grow beyond their usual practices and think and act out of the box.

Top 5 Challenges of an IoT System
We have seen the benefits of IoT applications. Now let us know what are the challenges that IoT poses and how they are affecting the deployment of IoT applications.
1. Inconsistent Hardware
A major challenge in IoT app development is the inconsistency created by different hardware in an IoT system.
Every manufacturing company will have its standards, security, and connection features.
In an IoT system, this causes a problem as devices from different vendors might not be able to connect with each other and work together.
To solve this technical inconsistency, users of an IoT system mostly have to stick to using devices of a single company.
Otherwise, the IoT application you develop may not be able to connect with all the devices.
Security is a prominent concern that keeps most people from implementing IoT solutions.
The lack of consistency that we discussed above also affects security.
Since there is no defined standard among companies, there are no set security rules. This causes a big problem.
Another factor is that there are a number of connected devices in an IoT system, which means there are multiple entry points for hackers to get in.
This makes the IoT system more vulnerable. Security checks have to be done separately for each entry point, which is a complicated process.
Connectivity is the crux of an IoT system. However, wireless connectivity is still a growing technology. Thus, enabling seamless connectivity at all times is a major IoT challenge.
And with billions of IoT devices being deployed year after year, it further complicates the connectivity issue.
It is expected that with the arrival of 5G technology, this challenge can be resolved once and forever.
5G will ensure uninterrupted connectivity, better speed, and support a large number of connected devices.
4. Government Regulations
Lack of proper government regulations is another challenge that IoT is facing.
It leaves businesses in much confusion when it comes to making decisions.
Because there are no strict regulations to follow, it gives rise to a situation where there is no standardization.
This further aids the security concerns as well because without sufficient regulation, the IoT systems are open to threats.
In the healthcare and financial industries, this lack of regulations causes many difficulties.
The demand for strict regulations and universal security standards for IoT is becoming more persistent today.
Billions of devices trying to coexist and operate through the same channels will inevitably result in congestion of signals.
In a mixed-signal environment, how a device will operate in the presence of another signal is a matter that is still under study.
This poses a massive challenge as it might most probably lead to collisions and data losses.
Imagine an IoT device stops operating in the midst of a crucial operation due to signal interference! The results could be drastic!
Thus, congestion is another challenge that the IoT system faces and needs to solve to ensure efficient working in all conditions.

Why Create a Custom IoT Application?
With the rising popularity of IoT technologies, everyone wants to develop IoT apps.
It has already made its presence known in several industries, as we saw above.
But being a versatile technology, it has a lot to offer to other markets as well.
For each sector, the requirements of IoT application development could be different.
For example, IoT devices in agriculture may not need a mobile interface, but if we take the fitness sector, it might be required.
Thus we see how the needs for IoT based apps vary from one to another.
Depending on your mobile app ideas and considering your target market, how you want your IoT app to be developed will also change.
The market for IoT app development will be saturated in a matter of years.
Right now, it is yet to explode. So this is the best time to find good IoT app developers and create a mobile app for your IoT system.
How to Create an IoT Application?
An IoT application involves several components, as we saw earlier in this blog. So creating an IoT application requires developers to follow specific steps.
1. Choose the Hardware
Hardware is an essential component of an IoT system, so it is necessary that you choose reliable hardware that will give you accurate data.
Hardware comes at the first layer of the hierarchy, so if it’s not chosen wisely, it will affect the success of the entire IoT application.
To make sure that the hardware is reliable, you have to carefully choose the device maker. Choose someone who guarantees quality, accuracy, and has a good reputation.
2. Choose the Industry
It is possible that your IoT application could come of service in multiple industries, but ideally, it is good to target a single industry.
By doing so, you will be able to add more customization to your IoT app development.
This will help in making it more efficient and providing a unique and quality experience.
Another factor for choosing an industry is it will also help in marketing your app.
When you have a specific target audience to appeal to, the probability of your app becoming a success is more.
3. Choose the Platform
Choosing the right platform is a crucial step in creating an IoT application.
There are several trustworthy platforms that support IoT app development.
HomeKit, Android Things, Azure IoT Suite, IBM Watson, and Oracle IoT are some of the proven IoT app development platforms.
It is essential to choose a reliable platform, as an IoT system might have multiple devices from multiple vendors, which could lead to technical inconsistencies.
Platforms like the one mentioned above can unify these multiple devices and create a consistent connection.
4. Define Scalability and Performance
If the IoT application you are creating does not support high-speed performance, then it can’t succeed.
Since most IoT systems involve continuous and real-time sharing of data, even a little lag could very much affect their working.
For example, if you are developing a connected car, it can’t afford even a second’s lag as the consequences could be drastic.
If your IoT system is related to body vitals measurement, then small lags won’t cause many problems. So depending on your need, you need to define the speed.
It’s also important to think about scalability in advance. Consider if, in the future, you plan to add more devices or deal with more data, would the system be good enough?
Will your app still work if you increase the number of users?
Keeping in mind the growth of IoT across industries, scalability is the factor that will ensure whether your app can remain relevant for a long time.
5. Think about User Experience
Since IoT applications are very closely connected to users, user experience is key in their development.
Your users might be using the app on an everyday basis, so their comfort and satisfaction define the rate at which they will embrace the app.
If your app has a very complicated UX and leaves users confused, it will make them stop using it.
It doesn’t matter if you have state of the art hardware and excellent software, if the app’s user interface fails to engage users, the whole system will break apart.
Study your target audience, research about the other applications in the market, find out their pros and cons, and then design your app accordingly.
6. Ensure Application Security
Since an IoT system involves a number of devices connected to the internet, it is highly vulnerable to threats.
Hence it is crucial to strictly define and implement the security policies involved with IoT app development.
You have to ensure the devices’ firmware security as well as the data security.
Often the data involved in IoT systems will be sensitive, hence any threat could lead to harmful consequences.
Since there are multiple entry points in an IoT system, ensuring security is somewhat more complicated than for regular applications.
However, its importance is also so much more.
