The Internet of Things (IoT) is transforming the way we live, work, travel, and conduct business. As more and more objects, devices, and places become interconnected, our world is increasingly becoming an intelligent, responsive, and automated environment.
What is Internet of Things
what exactly is the Internet of Things? The IoT refers to the network of physical objects embedded with sensors, processing ability, software, and connectivity that enables these objects to collect and exchange data with minimal human intervention. Simply put, the IoT allows physical things or “things” to be connected to the internet and to each other. These connected things have the ability to sense, process data, and communicate.The IoT ecosystem comprises of several components:
- Physical devices and objects - The “things” in the Internet of Things can include a wide variety of physical objects such as smart home appliances, wearable fitness trackers, industrial machines, connected cars, medical devices, and more. These objects contain embedded processors and sensors that allow them to connect to the internet and other devices.
- Connectivity - IoT-enabled devices connect to the internet and each other using protocols like WiFi, Bluetooth, LTE, 5G, etc. This allows data transfer between devices, sensors, networks, and applications.
- Data storage and analytics - The huge amount of data generated by IoT devices is stored and analyzed in the cloud. Advanced analytics turned this raw data into meaningful insights.
- User interfaces - Mobile and web dashboards allow users to remotely monitor, control, and set preferences on connected IoT systems and devices from anywhere.
The IoT ecosystem has evolved tremendously over the past decade thanks to technological advancements in sensors, broadband connectivity, big data analytics, and more. According to Statista, the number of IoT-connected devices worldwide was 8.74 billion in 2020 and is projected to reach 38.6 billion by 202512. The global IoT market is estimated to be worth over $1.6 trillion by 2025
Applications of IoT Technology
The Internet of Things finds operation across a different range of industries and use cases. Here are some of the crucial parts where IoT is bringing substantial transformation.
Smart Homes
Smart home technology is one of the most common applications of IoT in the consumer segment. Smart home devices such as connected thermostats, security systems, cameras, locks, lights, appliances, and more allow users to monitor and control their home environment remotely via smartphone. Voice assistants like Amazon Alexa and Google Home are becoming the hub for controlling other IoT-enabled devices.Industrial IoT
Industrial IoT refers to the application of IoT technology in industrial and manufacturing environments. IIoT(Industrial Internet of Things) enables features like predictive maintenance, asset tracking, automation, supply chain optimization, and more through IoT sensors in production equipment, warehouses, fleets, and products.According to MarketsandMarkets, the IIoT market size is estimated to grow from $88.2 billion in 2020 to $106.1 billion by 20261. Another source, Grand View Research, estimates the IIoT market size to grow from $216.13 billion in 2020 to $1.1 trillion by 2028
Smart Cities
Urban areas are turning into “smart cities” with the implementation of advanced IoT systems for traffic monitoring, green energy, waste management, law enforcement, and other public services. IoT-enabled infrastructure improves efficiency, sustainability, and livability.According to Streetline, their smart parking solutions can reduce the time spent searching for parking by 43%, increase parking revenue by 20-30%, and reduce parking-related emissions by 30%
Retail and Supply Chain
In retail, IoT enables automated checkout, smart shelves for inventory optimization, digital data, surveillance, and supply chain tracking.According to Global Market Insights, the IoT in retail market size was $28 billion in 2019 and is projected to reach $94 billion by 2027. Other sources have different estimates, such as IMARC Group, which projects the market size to reach $147 billion by 2028, and Allied Market Research, which projects the market size to reach $177.9 billion by 2031.
Healthcare
The Internet of Medical Things (IoMT) allows the healthcare industry to improve patient monitoring, asset tracking, disease management, dosage errors, record keeping, and more through connected devices and wearables.According to MarketsandMarkets, the IoMT market is expected to grow from $72.5 billion in 2020 to $188.2 billion by 2025, at a CAGR of 21%
The applications of IoT are nearly across every industry. Other Crucial parts using IoT include energy, transportation, agriculture, insurance, financial services, and more. IoT adoption will accelerate as costs come down and benefits become more apparent across use cases.
IoT Architecture and Key Technologies
An IoT system is made up of components that enable devices to connect, transmit data, and integrate with applications and analytics tools.Here are the components that make up an IoT architecture:
Physical Devices/Things
The “things” in IoT refer to the end-point physical objects and devices that have connectivity and data exchange capabilities. It includes sensors, microcontrollers, chips, actuators, electronics, etc. embedded within the device. Common examples are smart thermostats, fitness trackers, autonomous vehicles, factory machines, etc.Connectivity
IoT devices connected to the internet and each other using a variety of protocols and networks like WiFi, Bluetooth, LTE, 5G, LoRaWAN, and Zigbee. Gateways and routers help connect devices to the wider internet and cloud platforms.Data Processing
The data generated by IoT devices gets aggregated and processed at the edge or in the cloud. Edge computing allows some analysis to occur locally on devices, while cloud platforms enable advanced centralized analytics.User Interface
The IoT ecosystem provides user interfaces like mobile and web dashboards for analytics visualization, monitoring, control, notifications, and configuration. Users can know insights and interact with devices and systems through these interfaces.IoT Platforms/Backends
IoT platforms like AWS IoT, Microsoft Azure, and Google Cloud IoT handle secure connectivity, data integration, device management, processing, and storage for massive numbers of devices and data points.IoT Security
Cybersecurity is a critical component in the entire IoT architecture. Security measures like encryption, access control, and device authentication help protect against breaches and attacks.In addition to this foundational architecture, other key technologies powering IoT include AI and machine learning, augmented reality, blockchain, 5G, and WiFi 6.
IoT Security Risks and Challenges
While the Internet of Things delivers substantial benefits across many sectors, it also introduces major new cybersecurity risks and challenges that must be addressed.Some of the top IoT security threats include:
- Data breaches - Sensitive user data collected by IoT devices can be stolen if not properly secured. Breaches can involve identity theft, privacy invasion, or espionage.
- Distributed denial-of-service (DDoS) attacks - Criminals can hijack thousands of poorly secured IoT devices to carry out massive DDoS attacks that disrupt or crash systems and networks.
- Device hijacking - Malware and hacking can allow threat actors to remotely take over IoT systems and use them maliciously. This presents safety and operational risks.
- Lack of encryption - Data transmitted between IoT devices and the cloud may not be adequately encrypted, exposing it to interception and theft.
- Insecure interfaces - Poorly designed user interfaces of IoT devices and dashboards can provide unauthorized access to configure or control systems.
- Regulatory non-compliance - Certain industries like healthcare and financial services have strict data security and privacy regulations that IoT systems need to adhere to.
Along with these threats, other challenges for IoT security include an extremely broad and growing attack surface, legacy systems lacking the latest security features, and resource constraints of low-power IoT devices.
A holistic approach combining device hardening, encryption, authentication, intrusion detection, access controls, and secure coding practices is imperative to mitigate risks across the entire IoT infrastructure. Security must be inbuilt into IoT systems by design.
