Nowadays, Java has been extensively used in industries as a reliable and portable object-oriented programming (OOP) language. To support novice students in learning Java programming, we have developed a web-based system called Java Programming Learning Assistant System (JPLAS). JPLAS offers the Code Writing Problem (CWP) among several types of exercise problems. A CWP instance requests a student to write a source code that will pass the provided test code in the assignment where the accuracy of the code is verified by running them on JUnit. In Java programming, every student should master basic OOP concepts, which can be challenging for novice students. This paper presents CWP instances for studying six basic OOP concepts including encapsulation, polymorphism, constructor, inheritance, abstract, and interface in JPLAS. Our preliminary evaluations of them confirm their validity. © 2023 IEEE.

This paper focuses on the 29GHz mmWave MIMO communication system in tropical environments, considering the impact of rain attenuation and providing a detailed analysis of channel estimation and system performance. Experimental results indicate that as the signal-to-noise ratio (SNR) increases, the mean square error (MSE) of channel estimation decreases. Under the same SNR conditions, MIMO systems with different antenna configurations exhibit distinct channel estimation error characteristics. Notably, in the 128x128 antenna configuration, the channel estimation error is most pronounced. Furthermore, increasing the number of training signals significantly reduces channel estimation errors, especially in the 128x128 antenna configuration. This study offers a performance evaluation of the 29GHz mmWave MIMO communication system in tropical regions, providing valuable insights for further research and optimization in this field. © 2024 IEEE.

Data breaches, identity theft, and the lack of user control within traditional digital identity management systems, it begs a more secure and decentralized alternative. In this study we propose a blockchain based digital identity management framework that implements privacy, security and transparency by employing distributed ledger technology. To provide tamper proof identity storage and automated verification, the proposed model uses cryptographic hashing and smart contracts. The use of a novel token-based access mechanism enables users to safely share their identity data with third parties, while keeping sensitive information out of sight. Security metrics are enhanced by 30% for data integrity with 45% reduction in unauthorized access attempts all through simulations. The framework also achieves improved efficiency reducing identity verification time by 40 percent compared to traditional systems. It offers a promising approach to address important vulnerabilities in centralized identity management in line with the development of marketable and user-friendly digital identity solutions. © 2025 IEEE.

Experimental evaluation of MU-MIMO in TDD environment for 5G NR using exploiting channel reciprocity

International Journal of Information Technology (Singapore) 2024年第7期16卷 4651-4666页

5G New Radio (NR) operates in two frequency ranges viz. Frequency Range 1 (sub-6 GHz band) and Frequency Range 2 (millimeter wave communication). It utilizes Time Division Duplex (TDD) communication, allowing the same frequency band for uplink and downlink transmission using sounding reference signals. These signals help estimate channel conditions for scheduling downlink traffic. Multi-User Multiple Input Multiple Output (MU-MIMO) technology enables simultaneous data transmission to multiple users using multiple antennas. This study examines MU-MIMO performance in TDD by analyzing variables like radio conditions, modulation schemes, code rates, precoding algorithms, and sub-carrier spacing. Simulation results show that Zero Forcing (ZF) precoding outperforms Block Diagonalization (BD) and Regularized Zero Forcing (RZF) in good radio conditions. However, in bad radio conditions, RZF performs better than ZF. Choosing higher code rates in 16 and 64-QAM and lower code rates in 256-QAM from the MCS table improves throughput. This indicates that MCS and user selection are crucial for higher throughput in TDD-based MU-MIMO for 5G NR. © Bharati Vidyapeeth's Institute of computer Applications and Management 2024.

Street lights currently use more energy than other types of lighting because of an inefficient mechanism that makes the bulbs use a lot of electricity. The suggested approach uses various sensors on intelligent streetlights to keep an eye on and manage the lights. It has sensors for measuring temperature, brightness, and power that control dimming levels and keep track of status. One Zigbee network serves as the connection point for these lights. In the modification, a cloud- and IoT-based installation was made. Through Zigbee -based data transmission, sensor values are recorded on a distant server known as the Cloud. Additionally, it lowers electricity theft. We include a trash can notice in addition to this street light idea. When the garbage can is whole, a machine automatically notifies the business as people approach the sun, and the brightness of the street lights changes or is increased. © 2024 IEEE.

MANETs use multi-hop wireless connections to connect nodes, and the topology often changes as nodes move around. Therefore, dynamic routing techniques are required. A multipath routing strategy all better services network factors, including delay, energy consumption, and network throughput in dynamic contexts, than using a single path routing system. Each protocol addresses a specific use case in a networking environment. This can be caused by various factors, such as random loss;delaying packet delivery due to this data loss would harm real-time applications. This study offers guidance on how to deal with the confluence of serious issues that plague MANETs. Among the Ad-hoc On-demand Multipath Distance Vector (AOMDV) routing protocol, this study proposes Coyote optimizer-based Multipath Routing to choose the most efficient route from the available options. The suggested optimizer has a novel algorithmic structure and techniques for balancing exploitation. When data packets are randomly lost, these protocols use an optimization procedure to identify well-organized routes with the highest fitness values, resulting in the least data traffic, shortest path, and residual energy possible. Here, a mechanism is introduced that allows the suggested model to use the TCP Congestion Control Improvement for Random Loss (TCP CERL) to improve the effective route. © 2022 IEEE.
