IoT devices that last: The role of device reliability engineering

IoT advancements have resulted in broad acceptance of different elements of our lives, such as ocean-based sensors, animal tracking collars, and smart baby monitors. However, these developments bring with them hazards that might influence device development, operation, and maintenance. From the first user experience to long-term client loyalty, developers must evaluate how each product will perform.

Promoting reliability

To solve these difficulties, two innovations must have IoT development which concentrates equally on firmware architecture as it does on design. 

1. Objectives: The market for IoT devices is predicted to increase significantly, with 14.4 billion linked devices by 2022 and 27 billion by 2025. Consumers are still concerned about hackers and problems, but adoption is still high. To address these issues, developers must provide dependable solutions. Consumer wearables and low-cost sensors may be inexpensive, but problems can damage a company’s brand and cash line. Industrial IoT applications may interrupt infrastructure operations, whilst healthcare gadgets containing sensitive data may be disastrous.

2. Security requirements: As user expectations rise, developers are under pressure to enhance device security due to multiple vulnerabilities in operating systems, microcontrollers, and connection stacks. Consumers want gadgets that secure their data and perform as promised. Governments are enacting stricter compliance and regulatory standards, such as the IoT Cybersecurity Act in the United States, the EU Cybersecurity Act, and France’s mandate that IoT device makers reveal repairability. These actions signal a movement towards increased regulation, encouraging developers to comply with fundamental security requirements right away.

By delivering individual device and fleet-level data to improve IoT and edge device delivery, new hardware development methodologies like as device reliability engineering (DRE) enable device producers to focus on enhancing products and customer happiness.

DRE Implementation for IoT Devices

Tip 1: Consider bugs while building: When developing devices, developers should take a proactive approach, anticipating issues and planning for regular patches and upgrades. This entails resetting devices to factory settings or outdated firmware versions and adhering to a Day-0 methodology. This technique provides continual algorithm refinement and device upgrades, allowing teams to confidently deploy products.

Tip 2: Actively consider security: When deploying products, developers must prepare how to update them in the event of breaches or known vulnerabilities that must be corrected. Other important security measures include signing firmware updates and demanding firmware validation on a device, as well as anti-rollback methods, which ensure safe delivery and an unencrypted state in transit. Another security need is to keep third-party libraries up to date. Because third-party code is prevalent and frequently responsible for important functionality such as connection or cryptography, developers must understand it, including its license(s) and accessible support.

Tip 3: Be ready for surveillance: It is not sufficient to just bring a product to market. Today’s devices must perform properly and provide unique features, as well as receive frequent upgrades and integrate smoothly with other apps, platforms, and devices—all while protecting client data. Remote device monitoring in the field is crucial for visibility into a fleet’s health as well as addressing consumers’ escalating needs. To address the demands for device monitoring, the development cycle effectively stretches into post-production. Over-the-air (OTA) monitoring of metrics (e.g., battery life, Bluetooth connectivity, crash-free hours, meantime among failures) enables faults to be detected—and repaired—with minimal inconvenience to the user, often before the user is even aware.


Software development teams are well aware that reliability engineering tools contribute to better overall products. Teams may use device reliability engineering to take an ongoing, observable, and highly efficient strategy. As a consequence, long-lasting items are placed in the ownership of loyal customers.
