Smart Cities: Traffic, Energy, and Waste Management
​Machine learning in IoT is transforming smart cities by enhancing traffic, energy, and waste management systems.​
Traffic Management
AI driven traffic systems are being implemented in cities to relieve congestion. A $350,000 trial has also seen South Australia put AI powered road cameras onto the roads, which use traffic flow information to change signal timings in an attempt to reduce delay and economic losses.
At a CAGR of 32.2%, the global AI for Smart City Traffic Optimization market, worth USD 7.5 billion in 2024, is to reach a market value of USD 122.3 billion during 2034. ​
Energy Management
The integration of IoT and the machine learning technique allows for smart energy usage in the smart city. Machine learning algorithms analyze data from smart meters and sensors to predict energy demand and optimize distribution, costing less to produce and also reducing the negative impact on the environment. Such systems can have a great benefit on improving the energy efficiency in urban areas. ​

Waste Management
Machine learning in IoT is also improving urban waste management. With sensors, smart bins can help monitor the number of waste and optimize the route, thus saving operational costs and helping reduce the environmental impact. For instance, in Wyndham City, Australia, smart bins have reduced garbage truck trips by 80% within six months.
Healthcare: Patient Monitoring and Anomaly Detection
​Machine learning in IoT is revolutionizing healthcare by enabling continuous patient monitoring and early anomaly detection. Smartwatches and biosensors, bearing wearable IoT devices, record real time data of all of their vital signs including the heart rate, blood pressure and oxygen saturation. This data is then analyzed by machine learning algorithms to detect deviations from the normal patterns for the physicians to take timely medical interventions.​
Remote Patient Monitoring
According to a new report, the global remote patient monitoring devices market is to register 19.1 percent compound annual growth rate (CAGR) from 2024 to 2032, reaching USD 203.68 billion by 2032, from the revenue level of USD 50.39 billion in 2024. The growth signals the steadily rising demand for IoT devices for continuous health tracking. For example, wearable sensors can automatically take health measurements from patients in places other than patient –visited clinics and save the need for frequent in –person visits .​
Anomaly Detection
Anomaly detection is possible with the help of the machine learning algorithms that diagnose unusual patterns in the data collection from the IoT devices that indicate that there could be some health issues. According to a study, via AI, the anomaly detection in smart healthcare can alert providers about possible health issues in real time to provide better patient care and lower costs .​

This innovation provides real-time monitoring and alert system for patient safety and ensures quality of life.​
Challenges and What’s Changing
​Machine learning in IoT is transforming industries by enabling intelligent data analysis and automation. However, there are several challenges that organizations have to deal with.​
Data Privacy and Security Concerns
​Integrating machine learning in IoT raises significant data privacy and security concerns. The phenomenal growth of IoT devices has increased the attack surface for cyber vulnerabilities. The number of IoT devices is expected to increase 13% from 2023 to the end of 2024, up to 18.8 billion. ​
It has caused the surge in these attacks targeting these devices. Specifically, one in three data breaches now involves an IoT device — and the fact remains that they’re prone to be vulnerable. ​In home networks, the average volume of attacks per device, per day, is ten. Security solutions like Bitdefender block approximately 2.5 million threats daily, underscoring the persistent risks. ​
One of the major reasons for such vulnerabilities is the poor security implementations of many IoT devices. A survey found that 44.5% of consumers do not even have any mobile security solution in use on their devices which makes them prone to malware, phishing, and data breaches. ​
This is also financially expensive for businesses. The average costs of data breaches involving the Internet of Things devices have proven to be higher and 34 percent of the affected enterprises have $5 million to $10 million of the losses. ​
Organizations are thus investing in advanced security solutions to address the challenges. According to Global Market Insights, the global IoT security market was worth $34.2 billion in 2023 and is to grow at a CAGR of 18.5%, reaching $112.4 billion by 2030. ​
With machine learning algorithms, we can implement IoT security to detect such threats and subsequently mitigate them in real–time. With these, such algorithms are able to use patterns and anomalies to provide proactive defense mechanisms to prevent cyberattacks.
Hardware Limitations and Data Volume
Integrating machine learning in IoT presents significant challenges due to hardware limitations and the vast volume of data generated by connected devices.​
Hardware Limitations
IoT devices can be limited in both computational resources, processing power, memory, and energy capacity. These limitations affect the deployment of such complex machine learning models directly on the devices. This is because typical microcontrollers in IoT devices may not have enough capabilities to run complex algorithms efficiently. In order to tackle this, researchers are designing models suitable for resource constrained hardware. There are various techniques for delivering the models on microcontrollers, such as model quantization and pruning. These models can achieve meaningful compression without sacrificing much accuracy, enabling more efficient on device processing. ​
Data Volume
There has been an exponential increase in data generation from IoT proliferation. By 2024, the world will generate a data base on the digitization of activities around the globe and the data volume is about 149 zettabytes. Additionally, processing and analysis of this immense data flow and storage challenges are tremendous ones. Latency and bandwidth constraints present such large scale data to traditional centralized cloud infrastructures in handling such data in an efficient way. However, to ease these problems, something called edge computing is taking up the process of processing of data closer to its source. This approach decreases latency of, and bandwidth usage for, machine learning applications in such IoT environments. ​
Emerging Solutions
Efficient machine learning models are not deployed enough, which incurs runtime latency, and current methods to quantify their cost do not work on very small devices. This development and reducing the need of constant data transmission to central servers remove the bandwidth issues and improve the real time processing capabilities. For instance, tailored accelerator chipsets have been developed to support the efficient on-device processing of machine learning algorithms and to allow the use of device side AIu functions in constrained resources environments. ​

Challenges in Scalability
The amount of data coming from billions of IoT devices is too immense to manage and process. Systems that utilize traditional centralized computing find it difficult to cope with these types of large-scale data due to the latency and bandwidth constraints. To get around these problems, machine learning models are being built on a large scale that can quickly mine valuable intelligence from the data generated by IoT. ​
Edge Computing Solutions
Processing data closer to its source has emerged as a critical solution and has become a very effective solution to the problem of edge computing reducing latency and bandwidth usage. This increased the efficiency of machine learning applications in the IoT ecosystem. ​
Cloud-Based Scalability
Cloud environments are to enable scalable machine learning models for the IoT data analytics. With cloud resources, large scale data processing can become easier and thereby one can take care of real time analysis and decision making. ​
Future Outlook
