IoT Challenges Are They Hard To Solve

IoT is one of the most advanced technologies today but still, but it is in its development phase and it still has so many things which are not been discovered yet. So this technology is mostly unknown and has so much potential undiscovered as do the challenges that come coupled with it. In this article, we will discuss what are the different kinds of IoT challenges that people face and how to mitigate them easily. In order to make it easier for you to understand we have classified the different kinds of challenges according to the location of the architecture where they originate.

IoT challenges

It was estimated that within 2025 the number of active IoT devices will reach 42 Billion and the arrival of 5g can take the number reach even higher. As one of the most experienced companies in the IoT field, we here at Kotai electronics understand how important it is to solve the challenges and vulnerabilities during the development of the IoT solution.

As we believe safety and security should be the top priority over the bells and whistles when we literally remove the barrier between the real and digital world. where devices are not only exchanged but have become conscious as well and there is a possibility of IoT being used for more and more industries like farming and healthcare in future. Finding out the problems should be our first step.

The Scalability Issue

IoT Node: Every device that is connected to the IoT system and provides sensory data while working under the cloud server is called a node.

Every business has the primary objective to grow. When this happens companies need to put more and more resources just to make their system more sophisticated. If the organization is using IoT solutions it has to scale the system too. When we consider the number of devices needed and the network strength needed to hold onto all that the scalability comes as a challenge for IoT. It is often categorised into two categories (1) Verticle Scalability and (2) Horizontal scalability

IoT challenges while scaling

Verticle Scalability It’s about strengthening the computing power or the resources that are backed into powering the node and Horizontal scalability is about upgrading the node completely itself. Even though the arrival of 5g and the proposed model of coupling IoT with cloud computing or edge computing is coming but still the need to provide routine services with time and increasing numbers of devices, increasing the location of the expensive storage, etc is still an IoT challenge.


With the increasing number of endpoints, the attack surface of the IoT also increases which causes numerous security challenges. The lack of privacy is one of the biggest concerns of IoT. Though everyone is trying to make advancements for solving the issue from both hardware and software perspectives, either from hardware or software POV.

For example, engineers are using RFID chips, newer versions of networks like 5G and other local network protocols for tackling security issues at a hardware level. From the software, POV technologies like end-to-end encryption, blockchain, and KMS are used to solve these IoT challenges. Yes, there will be newer technologies which would bring newer threats and both of these technologies will fall short of these. So its another IoT challenge

Energy Efficiency

As IoT is mainly wireless so it quite natural that it will be vastly used in remote places. So battery efficiency is still very much needed. Unfortunately, even though IoT consumes minimal power the limitation of power consumption is still an IoT challenge that we still need to overcome.

We here at Kotai Electronics developed energy-efficient routing protocols to reduce power consumption. Our passionate engineers with years of experience have developed efficient systems for optimal use of network power while retaining the battery life in the system. We hare have successfully incorporated a wake-sleep feature for better battery life.

challenges of IoT

We also smartly use our the topology for least data loss. Implementation of renewable energy can also be a great way to make that happen, though the development of IoT is still going on it can be a great way to make IoT systems more accessible in rural areas.

The use of more advanced wireless charging can be effective but things go quite tuff to perform when we take large IoT applications into account which have so many functionalities and needs to be robust to withstand harsh weather outside. All these together seem a great way to solve the energy efficiency IoT problem but we are still far away from the hardware perspective we still have a far way to go before we can build something to solve the power consumption problem of IoT. As we need to balance fidelity and power efficiency. So it’s another IoT challenge that we need to overcome.

Providing Encryption

As we said before encryption is a great way to provide security to the IoT applications and platforms but often providing the security is a huge task to fulfil. Encryption prevents hackers from accessing data. It’s an IoT challenge as it was easier to perform in traditional computers but the modern systems where every day there is a new technology it’s quite hard to implement encryption without hampering compatibility.

Handling The Volume

The IoT space is growing and the data that those devices produce are massive in volume. As we said before the the the the number of IoT will cross the 42 billion mark. This sheer number of devices will have so increased numbers of devices the gathered data will also be huge.

This huge amount of data needs to be stored and processed without it all the data collection will be in vain. For that reason, it needs to be transmitted to the server and get processed there. IoT is used mostly in remote places with limited Internet bandwidth, making it difficult and often expensive to transmit the collected data. So it’s another IoT challenge that we face and this will also increase in future.

Managing The Complexity

A good IoT device is built to handle big data. IoT devices collect much information as possible and send it to cloud-based servers for processing. This data set is not only massive in terms of volume but also complexity, as the collected dataset is highly dispersed and unstructured. These data provide little to no context and perspective. This data must be carefully timestamped, indexed, and correlated with other data sources to make the context required for effective decision-making.

challenges in IoT

The data that is produced is super hard to interpret effectively and efficiently. Many tools designed to manage complex datasets cannot cope with the volume of data that IoT devices produce. On the other hand, systems that are capable of doing that may not be needed everywhere as they can cost quite high and that heavy software capability coupled with slow internet can show latency.

Insufficient testing

There are very few companies that develop IoT at this time so the companies who are in the market have a huge load of working on their head because of the increasing demand for IoT. The customers are always in a hurry to build here solutions and the company often don’t get enough time to test the solution properly. It happens mostly when you are developing a new IoT solution and can be avoided if you give enough time to get it tested. With the increasing numbers of manufacturers who are so much eager to properly get tested the security becomes weak.

Sure, they can be given security patches, updates and other security updates but still doing all that in a hurry puts the IoT system in danger of hackers and malware on the other hand building the solution in laid back manner can delay the development and give your competitors an edge for a short time. It’s another IoT challenge.

Users Prefer Default Password

Another IoT challenge appears when people who are using Weak credentials like birth year and login details leave nearly all IoT devices vulnerable to password hacking and brute force. It becomes more vulnerable when users don’t change the default password. It puts the user and its customer’s valuable information in danger.

what are the challenges of IoT

Time Consuming

Embedded systems are lightly constrained by cost.
The need originates to drive better approaches when designing IoT devices in order to handle the cost modelling or cost optimally with digital electronic components.
Designers also need to solve the design-time problem and bring the embedded device at the right time to the market.


One of the biggest challenges of IoT. As it happens the very first time when trying to connect it with other devices, applications and cloud platforms. The information that the IoT collects from the environment is highly valuable and useful but this needs to be transmitted so when the network is unreliable it causes IoT challenges for things like where IoT sensors are required to monitor process data and supply information.


IoT is a bunch of different kinds of devices coming together forming an amalgamation of technologies. As we are thinking about keeping an IoT in use for a long and not changing it right away it has to be future-ready. The IoT needs to have a balanced function of software and hardware. It’s another IoT challenge to build the device and platform that can best performance despite heavy device rates and fixings.

Lack of Skill

All the development challenges can only be handled by properly skilled professionals working in the IoT industry. Being a new technology that is quite hard to find. This will always be an IoT challenge.

Malware and Ransome ware

IoT challenges do not every time comes from the development part it can also come after it has been working perfectly for a number of people. As the devices are connected to so many devices and have a large attack surface it is very much prone to the attack of ransomware. It uses the same encryption to lock out users from various devices and platforms and still uses a user’s valuable data and info.

IoT BoTNet

IoT botnet workers can manipulate data privacy, which can be a dangerous thing, especially at a time when the crypto market can decide many things. As the mal-intentioned hackers can manipulate the exact value and creation of cryptocurrencies.

Blockchain companies are trying to boost security. Blockchain technology itself is not particularly vulnerable, but the app development process is, so it’s another IoT challenge.


So these are the IoT challenges that people face whether it’s during the development or while it is being used. It can be either caused by the time of development or it can cause by hackers or malware. Every technology has its challenges. For IoT, it’s not more or less than that it’s a new technology and we have yet to find out things about it.

So, why do we just don’t wait till it gets used up? because the people who took the risk and implemented new technologies are the ones who won in the world. Now the choice is completely yours whether you want to implement IoT into your systems or not. hope you liked our article thankyou for reading, and have a great day.
