Quality-Aware Data Aggregation in Environmental WSNs Using Autoencoder Filtering

Ayobami Adedokun — 2025-10-31

Environmental monitoring using Wireless Sensor Networks (WSNs) requires accurate and reliable data to support real-time decision-making. However, traditional data aggregation techniques often suffer from issues such as redundancy, noise, outliers, and unreliable readings, which compromise data integrity. This paper proposes a hybrid quality-aware data aggregation method that integrates autoencoder-based anomaly detection with rule-based filtering to enhance data fidelity. The autoencoder identifies anomalies through reconstruction error analysis, while the rule-based system applies sensor-specific thresholds to eliminate invalid values. The approach was implemented and simulated in MATLAB using real-world sensor data patterns. Performance was evaluated against conventional LEACH, PEGASIS, K-LEACH, and MABRL protocols based on metrics such as aggregation accuracy, packet delivery ratio, data loss rate, routing overhead, and end-to-end delay. Results show that the proposed method consistently achieves higher accuracy across various sensor types and significantly improves network reliability and communication efficiency. It also reduces unnecessary transmissions, leading to lower energy consumption and extended network lifespan. This work presents a robust solution for ensuring high-quality data aggregation in environmental WSN applications, contributing to more accurate and sustainable environmental monitoring systems.

This article examines the creation and execution of a College Community Online Voting System, aimed at modernising the election process in academic institutions through the use of digital technology to improve participation, security, and administrative efficiency. The main aim of this system is to offer a seamless, accessible, and secure platform for executing diverse voting activities, such as student elections, faculty surveys, and decision-making procedures. Through the resolution of the drawbacks associated with conventional paper-based voting, including difficulties with administration, vulnerability to fraud, and restricted accessibility, this technology seeks to enable a more equitable and effective voting process. The project involves developing a web-based application that includes characteristics necessary for a democratic voting process, such as secure user authentication, real-time vote tracking, and robust data protection methods. The system utilises sophisticated cryptographic methods and stringent security rules to guarantee the integrity and confidentiality of each vote, alleviating concerns regarding data tampering and unauthorised access. The system's efficacy and user-friendliness have been demonstrated through a pilot implementation in a college context, which has resulted in significant improvements in administrative workflow and voter engagement. Feedback from this pilot indicates a substantial improvement in the overall voting experience, with users valuing the system's user-friendliness and the dependability of the voting process. The innovation of the proposed system resides in its customised strategy for meeting the distinct requirements of academic institutions, integrating modern web technologies with specific security protocols to develop a platform that is both versatile and secure. This method establishes a standard for future advancements in digital voting systems and enriches the wider discussion on the incorporation of technology in democratic practices within educational settings. The College Community Online Voting System demonstrates the capacity of technology to enhance democratic participation and administrative effectiveness in educational environments.

The Influence of Smart Infrastructure, Cultural Heritage Preservation, and Green Mobility on Urban Sustainable Tourism Development: The Mediating Role of Tourist Satisfaction

Zheng Yao OOI — 2025-10-31

This paper investigates the multidirectional nature of the relationship between smart infrastructure, preservation of cultural heritage, and green mobility in the context of sustainable tourism development in the city, with the mediating variable being the tourists' satisfaction. This paper draws on the Sustainable Development Theory and the Triple Bottom Line to examine the relationship between the elements and Sustainable Development Goals (SDGs) 11 and 12, and how they contribute to sustaining a sustainable and inclusive tourism ecosystem. This paper employed a quantitative research design, in which a structured questionnaire was administered online to 252 Chinese students studying in Malaysia who are all experienced urban tourists in both China and Malaysia. Adapted constructs were those based on a proven scale, with a five-point Likert scale, and PLS-SEM was the means of analysis. A measurement reliability and validity test, a structural relationship test, and a mediation effect test were measured by the results of the analysis through bootstrapping. As the results suggest, the slight or non-significant effect of smart infrastructure and cultural heritage preservation on tourist customer satisfaction and sustainable outcomes is noticed. Relative to this, green mobility is a highly strong driver in shaping tourist satisfaction, not to mention urban sustainable tourism planning, which is why it ought to be central in creating sustainable urban destinations. This study is relevant to the discussion of sustainable tourism, as it emphasizes the importance of considering the ecologically friendly movement and integrating IoT technologies into tourist-focused solutions, while also revitalizing cultural heritage through new forms of communication.
