DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi

4. IOT DEVELOPMENT BOARD
An IoT (Internet of Things) development board is a hardware platform that is
designed to provide a convenient and cost-effective way for developers to create
and prototype IoT devices and applications. It typically consists of a
microcontroller or microprocessor, sensors and/or actuators, wireless
connectivity, and various other components required for interfacing with the
physical world and connecting to the internet. They offer a wide range of features
and capabilities, and the choice of the board depends on the specific
requirements of the project.
Wireless connectivity is a critical feature of IoT development boards, allowing
them to connect to the internet and interact with cloud-based services and other
devices. Wi-Fi and Bluetooth are the most common wireless protocols used, but
some boards also support cellular connectivity, LoRa, and other long-range
wireless technologies.
5. Programming and development environments for IoT development boards vary,
with some boards using familiar programming languages like C++ and Python,
while others may require more specialized languages or development
environments. However, many boards support Arduino IDE, which is an open-

13. Computer networks that are not connected by cables are called wireless
networks. They generally use radio waves for communication between
the network nodes. They allow devices to be connected to the network
while roaming around within the network coverage.
14. Types of Wireless Networks
1. Wireless LANs − Connects two or more network devices using
wireless distribution techniques.
2. Wireless MANs − Connects two or more wireless LANs spreading
over a metropolitan area.
3. Wireless WANs − Connects large areas comprising LANs, MANs and
personal networks.
Examples of wireless networks
• Mobile phone networks
• Wireless sensor networks
• Satellite communication networks
• Terrestrial microwave networks
15. Advantages of Wireless Networks
1. It provides clutter-free desks due to the absence of wires and cables.
2. It increases the mobility of network devices connected to the system since
the devices need not be connected to each other.
3. Accessing network devices from any location within the network coverage
or Wi-Fi hotspot becomes convenient since laying out cables is not
needed.
4. Installation and setup of wireless networks are easier.
5. New devices can be easily connected to the existing setup since they
needn’t be wired to the present equipment. Also, the number of equipment
that can be added or removed to the system can vary considerably since
they are not limited by the cable capacity. This makes wireless networks
very scalable.
6. Wireless networks require very limited or no wires. Thus, it reduces the
equipment and setup costs.
16. What is a Wi-Fi or wireless network vs. a wired network?
• A wireless network allows devices to stay connected to the network but roam
untethered to any wires. Access points amplify Wi-Fi signals, so a device can
be far from a router but still be connected to the network. When you connect
to a Wi-Fi hotspot at a cafe, a hotel, an airport lounge, or another public
place, you're connecting to that business's wireless network.
• A wired network uses cables to connect devices, such as laptop or desktop
computers, to the Internet or another network. A wired network has some
disadvantages when compared to a wireless network. The biggest
disadvantage is that your device is tethered to a router. The most common
wired networks use cables connected at one end to an Ethernet port on the
network router and at the other end to a computer or other device.
• Previously it was thought that wired networks were faster and more secure
than wireless networks. But continual enhancements to wireless network
technology such as the Wi-Fi 6 networking standard have eroded speed and
security differences between wired and wireless networks.
17. How to deploy a wireless network
1. Centralized Deployment: The most common type of wireless network
system, centralized deployments are traditionally used in campuses where
buildings and networks are in close proximity. This deployment
consolidates the wireless network, which makes upgrades easier and
facilitates advanced wireless functionality. Controllers are based on-
premises and are installed in a centralized location.
2. Converged Deployment: For small campuses or branch offices,
converged deployments offer consistency in wireless and wired
connections. This deployment converges wired and wireless on one
network device—an access switch and performs the dual role of both
switch and wireless controller.
3. Cloud-Based Deployment :This system uses the cloud to manage
network devices deployed on-premises at different locations. The solution
requires Cisco Meraki cloud-managed devices, which provide full visibility
of the network through their dashboards.
