artificial intelligence of things (AIoT)

What is artificial intelligence of things (AIoT)?

Artificial intelligence of things (AIoT) is the combination of artificial intelligence (AI) technologies and the internet of things (IoT) infrastructure. AIoT's goal is to create more efficient IoT operations, improve human-machine interactions and enhance data management and analytics.

AI is the simulation of human intelligence processes by machines, especially computer systems, and is typically used in natural language processing, speech recognition and machine vision.

IoT is a system of connected devices, mechanical and digital machines, or objects with unique identifiers with the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. A thing in IoT can be a person's heart monitor implant, an automobile with built-in sensors to alert the driver when tire pressure is low or any other object that can be assigned an IP address and transfer data over a network.

How does AIoT work?

In AIoT devices, AI is embedded into infrastructure components, such as programs and chipsets, which are all connected using IoT networks. Application programming interfaces (APIs) are then used to ensure all hardware, software and platform components can operate and communicate without effort from the end user.

When operational, IoT devices create and gather data, and then AI analyzes it to provide insights and improve efficiency and productivity. Insights are gained by AI systems using processes such as data learning.

Primarily, AIoT systems are set up either as cloud-based or edge-based.

Cloud-based AIoT

Commonly referred to as IoT cloud, cloud-based IoT is the management and processing of data from IoT devices using cloud computing platforms. Connecting IoT devices to the cloud is essential since that's where data is stored, processed and accessed by various applications and services.

Cloud-based AIoT is composed of the following four layers:

1. Device layer. This includes several types of hardware, including tags, beacons, sensors, cars, production equipment, embedded devices, and health and fitness equipment.
2. Connectivity layer. This layer comprises fields and cloud gateways consisting of a hardware or software element that links cloud storage to controllers, sensors and other intelligent devices.
3. Cloud layer. This consists of data processing via an AI engine, data storage, data visualization, analytics and data access via an API.
4. User communication layer. This layer is made up of web portals and mobile applications.

Edge-based AIoT

AIoT data can also be processed at the edge, meaning the data from IoT devices is processed as close to these devices as possible to minimize the bandwidth needed to move data, while avoiding possible delays to data analysis.

Edge-based AIoT consists of the following three layers:

1. Collection terminal layer. This covers a range of hardware devices, such as embedded devices, cars, manufacturing equipment, tags, beacons, sensors, mobility devices, and health and fitness equipment that are connected to the gateway over existing power lines.
2. Connectivity layer. This consists of the field gateways that the collection terminal layer is connected to over existing power lines.
3. Edge layer. This layer includes facilities for data storage, data processing and insight generation.

Applications and examples of AIoT

Although many AIoT applications focus on the implementation of cognitive computing in consumer appliances, the following are several examples of the wider use of AIoT:

• Smart cities. Smart technology, such as sensors, lights and meters, are used to collect data that's designed to help improve operational efficiency, drive economic growth and improve the quality of life for residents.
• Smart retail. Retailers use smart cameras to recognize shoppers' faces and detect if they've scanned their items at the self-checkout before leaving the store.
• Smart homes. Smart appliances learn through human interaction and response. AIoT appliances can also store and learn from user data to understand user habits to provide customized support.
• Smart office buildings. AI and IoT converge in smart buildings. Companies opt for a network of smart environmental sensors installed within their offices that detect the presence of people and automatically alter the lighting and temperature to maximize energy savings. In addition, facial recognition technology enables smart buildings to control access by using linked cameras and AI to compare live photos with a database to determine who gets access.
• Enterprise and industrial. Manufacturers use smart chips to detect when equipment isn't functioning properly or a part needs to be replaced.
• Social media and human resources (HR). AIoT tools can be integrated with social media and HR-related platforms to create an AI decision-as-a-service function for HR professionals.
• Autonomous vehicles. These vehicles rely on multiple video cameras and sensor systems to gather data about nearby vehicles, monitor driving conditions and look for pedestrians.
• Autonomous delivery robots. Sensors gather data about the robot's environment -- for example, a warehouse -- and then use AI to make traversal-based decisions.
• Healthcare. Medical devices and wearables collect and monitor real-time health data, such as heart rate, and can detect irregular heartbeats.
• Wearable devices. Wearable technology can monitor and analyze personal health data to offer insights into a person's fitness, sleep and general well-being.
• Collaborative robots (cobots). Cobots are intended to assist people in the manufacturing and assembly of components. They aid humans in various tasks, such as production, assembly, packaging and quality control of products, by using data from IoT devices and AI tools, including computer vision.
• City brains. City brains are intended to promote urban development by combining machine intelligence and real-time municipal data. For example, intelligent AIoT systems can process massive logs, videos and data streams from systems and sensors throughout an urban center to detect issues such as illegal parking, road accidents and changing traffic lights.

What are the benefits and challenges of AIoT?

Benefits of AIoT include the following:

• Increased operational efficiency. AI-integrated IoT devices can analyze data to reveal patterns and insights and adjust system operations to become more efficient.
• Ability to adjust on the fly. Data can be generated and analyzed to identify points of failure, which enable the system to make adjustments as needed.
• Data analytics. Employees don't have to spend as much time monitoring IoT devices, thus saving money.
• Scalability. The number of devices connected to an IoT system can be increased to optimize existing processes or introduce new features.
• Transformational technology. AIoT is transformational and mutually beneficial for both types of technology, as AI adds value to IoT through machine learning capabilities and improved decision-making processes. IoT adds value to AI through connectivity, signaling and data exchange. AIoT can improve businesses and their services by creating more value from IoT-generated data.
• Enhanced security. IoT devices can be susceptible to security risks. However, AI can identify and avert these risks since AI algorithms can analyze data from sensors to discover anomalies and potential security breaches. For example, AI can analyze security camera footage to spot suspicious activity and notify security staff.
• Reduced human error. Businesses lose millions of dollars each year as a result of human error. By integrating machine learning with IoT technology, organizations can effectively reduce errors. In normal workflows, data must pass through multiple phases or locations, creating more opportunities for human errors, such as data entry mistakes, to occur. AIoT mitigates these risks by analyzing information at its source. Minimizing data movement and reducing the number of intermediaries involved decrease the chances of errors significantly.
• Personalization. While IoT devices can gather information about user preferences and behavior, AI can use this information to further tailor user experiences. For example, a smart speaker can use AI to learn a user's musical preferences and generate customized playlists automatically.

Along with its benefits and use cases, there are also instances where AIoT could fail, causing a backup in production or other negative consequences. For example, autonomous delivery robots that fail might cause a delay in the delivery of a product; smart retail stores could fail to read a customer's face, leading to the customer accidently stealing a product; or an autonomous vehicle might fail to read its surroundings, such as an oncoming stop sign, and cause an accident.

The following are some additional challenges associated with AIoT:

• Cybersecurity issues. The growing number of devices connected through AIoT increases the risk of cyber attacks and security breaches.
• Complexity. IoT and AI technology integration can be challenging and demand particular knowledge and abilities.
• Data management concerns. Effective data management strategies are required for processing the data gathered from various sensors.
• High cost. Due to the need for specialized equipment, software and employees, executing AIoT technologies can be costly.
• Privacy concerns. There are concerns about how data acquired by AIoT devices is handled and stored, which could result in privacy issues and violations.

What is the future of AIoT?

With the integration of AI, IoT creates a much smarter system. The goal is to have these systems make accurate judgments without the need for human intervention.

Digital transformation and the collaboration between AI and IoT have the potential to tap into unrealized customer value in several industry verticals, including edge analytics, autonomous vehicles, personalized fitness, remote healthcare, precision agriculture, smart retail, predictive maintenance and industrial automation.
