Python 3.8 offers several advantages for software development. It is an object-oriented programming language with dynamic typing and automatic memory control. Python is cross-platform, making it suitable for various operating systems. It has a vast collection of libraries and modules for mathematical operations and methods, simplifying code reading and writing. Additionally, Python provides tools for graphical user interface designing. Despite its slower speed compared to other languages, Python's flexibility and ease of use make it a great choice for creating cross-platform desktop applications with graphical interfaces and mathematical operations. The multiprocessing module can address speed limitations, while removing unused object links during debugging can solve memory overflow issues.

The Kneed library implements the 'knee locator' method in Python programming language, specifically designed for calculating the optimal number of clusters in a wireless sensor network based on the device's position in space. By utilizing this library, researchers and developers can efficiently determine the ideal clustering configuration for their sensor networks, ensuring optimal performance and resource utilization. The Kneed library plays a crucial role in enhancing the scalability and efficiency of wireless sensor networks, enabling them to handle large-scale deployments and complex data processing tasks effectively.

LEACH protocol selects cluster heads based on a probability calculation for each node. The probability, P_i, considers the remaining energy (E_i) of the device, the maximum energy (max(E)) in the network, and the minimum distance (min(D_station)) between the node and the base station (D_i, station). The Fuzzy C-Means cluster technique divides IoT devices into fuzzy clusters, assigning membership coefficients to each node based on their distance to cluster centers. The cluster head is chosen based on the distance to the cluster center and the remaining energy of the device. The network topology remains the same as in the LEACH protocol, as depicted in Figure 3.

The energy consumption functions for IoT devices in a network include three primary functions: sending byte-messages, receiving byte-messages, and aggregating received data. The energy consumed by the transmitter to send k bytes of information on distance D is given by E = E0 + E1 * k + E2 * Dij. The energy consumed by the receiver to receive k bytes of data is E = Er * k. The energy consumed by the device electronics to aggregate k bytes of received data is E = EA * log(k). These functions help in understanding the energy consumption patterns of IoT devices in a network and optimizing energy usage for better performance and network lifetime.

The developed software tested on two specific topologies of wireless sensor networks. The first topology was randomly generated, while the second represented a smart farm case. The randomly generated topology consisted of forty devices within a 150x150 meters space, with the base station located in the center. The smart farm topology was used for monitoring soil state, temperature, and air humidity in agricultural industries. These tests allowed for an independent comparison of optimization methods.

The research shows that particle swarm optimization (PSO) methods are highly effective in node management systems for routing methods. The study tested various routing methods with and without sleep scheduling systems on two given topologies. The results indicate that the effectiveness of PSO methods in node management is significant, with a less than 5% difference in effectiveness when using sleep scheduling systems. The charts presented in the study demonstrate that the use of sleep scheduling systems slows down the decrease in energy consumption and the number of active nodes, indicating that the system is effective in both LEACH and Fuzzy C-Means routing methods. Overall, the research highlights the benefits of using PSO methods in node management systems for routing methods.
