4 Challenges to Consider Before Creating an IoT Device

Key Challenges in IoT Device Development

The Internet of Things (IoT) is sweeping the technology industry and has triggered the fourth industrial revolution. More and more companies are committed to IoT development, however, many companies do not fully assess potential challenges before embarking on development. This article will focus on four key challenges in the development process of IoT devices:

1. Connectivity

How the device is connected depends on its usage environment. Home smart devices can usually connect to Wi-Fi, while devices such as agricultural IoT or smart cars may only rely on cellular networks. As IoT technology continues to evolve, ensuring future compatibility of device connectivity is crucial. Choosing the right connection scheme requires a trade-off between cost and performance. For example, the cost of transmitting data through a cellular network is high, and edge computing or blockchain technology may need to be considered to reduce dependence on the cloud.

2. Security and Privacy

There is a fundamental difference between IoT security and traditional network security. The following aspects need to be paid attention to:

• Physical Security: IoT devices are usually exposed and lack physical protection. When designing, the device must be tamper-proof and malicious attacks must be prevented. Encrypting the data stored on the device is also crucial.
• Security of Data Exchange: Ensure secure data transmission from sensors to gateways to the cloud requires the use of an encrypted transmission protocol, and consider authentication and authorization.
• Cloud Storage Security: Data stored in the cloud is equally fragile. The platform should provide appropriate encryption and access control.
• Update: Vulnerabilities may still appear even if the code and hardware are strengthened. Plans need to be made to quickly fix vulnerabilities and push patches to users safely. Over-the-air upgrade (OTA) is a commonly used update mechanism, but it needs to be ensured that it does not become a security vulnerability.

In addition, relevant laws and regulations must be followed, and it is recommended to anonymize customer data and avoid storing personally identifiable information (PII).

3. Flexibility and compatibility

The Internet of Things field is changing rapidly, and product design needs to consider future technical support. Dedicated hardware provides the best performance, but may limit the introduction of updates and new features. Choosing the right storage and computing resources and IoT operating systems (such as Linux, Brillo, or Windows IoT) can flexibly expand device functionality, although it may slightly reduce performance. Some manufacturers even allow developers to extend device functionality by providing APIs and SDKs. In addition, devices should be seamlessly integrated with users’ existing IoT ecosystem to avoid increasing complexity and difficulty in use.

4. Data collection and processing

Planning is required to handle the collected data. First, evaluate the amount of data to expand cloud storage. More importantly, how to effectively utilize data. This includes hiring data scientists and using the right analytics and machine learning tools to extract valuable insights from the data. IoT data can be used to: supplement existing data, user profiles and segments, and improve products.

Summary

The development of IoT products faces many challenges, and this article lists only some of the main challenges. Ignoring these challenges can lead to development failure.
