Secure and Efficient Routing in Fog-Enabled VANETs: A Clustering-Based Approach

Vehicular Ad Hoc Networks (VANETs) play a crucial role in intelligent transportation systems (ITS) by enabling seamless vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication. However, VANETs face significant challenges related to security, routing efficiency, and dynamic load balancing. This paper proposes a novel approach integrating clustering-based routing, fog computing, and authentication mechanisms to enhance network performance. The article proposes a new method for node authentication and redistribution of loads in vehicular ad-hoc networks (VANETs). The proposed method is designed to do better for VANETs in all aspects related to secure node authentication and the efficient load assignment among fog nodes. The approach uses a polynomial-based node authentication protocol and balances the network load dynamically by evaluating two parameters: Network Availability Bandwidth (NAB) and request count. Simulation-based performance evaluation was carried out for comparisons with existing algorithms. Metrics of comparison included throughput, packet delivery ratio (PDR), and latency. The proposed method clearly shows all improvements over existing algorithms. Throughput increased by 8591.86 packets per second; PDR improved to 0.833; latency was cut down to 6.4951 seconds, which makes it a potential candidate for performance enhancement in VANETs.

EcoCycle: A Deep Learning-Based Waste Categorization and Management System for Sustainable Smart Cities

Waste management is a critical environmental and economic issue worldwide. Existing waste segregation ac- tivities are inefficient, resulting in high landfill contributions and environmental contamination. In this paper, an artificial intelligence-based waste categorization and management system, EcoCycle, is proposed that utilizes deep learning models like VGG16, ResNet50, and DenseNet121 for automatic classification of waste materials. EcoCycle is equipped with a gamification system based on mobile, a marketplace for recyclables supported by blockchain, and an IoT-based network of intelligent bins for real-time monitoring. Experimental results show 92.36% classification accuracy with DenseNet121, which is improved compared to other implementation results. User survey with 500 users shows a 98% positive effect on user experience and increased awareness about sus- tainability issues. The proposed system contributes significantly towards processes related to circular economies and the goals of smart city initiatives, and it has high global applicability potential for urban waste management systems.

Brgy 12, Dapa, Surigao del Norte.The first part of the questionnaire gathered respondents’ profiles and was analyzed using count and percentage distribution, while the second and third parts were analyzed using mean and standard deviation. The analysis of variance (ANOVA) was applied to assess significant differences in the factors affecting reading comprehension challenges.Findings revealed significant insights into the reading habits and attitudes of first-year BEED students at SIIT. The majority of respondents, aged between 18 and 19, were predominantly female, and books were the most common reading material available to them. Most students reported reading sometimes. Results indicated a concerning trend in their attitudes towards reading, reflecting a lack of motivation. Data analysis demonstrated that age, sex, reading materials, and frequency of reading significantly influenced reading comprehension.Variables were ranked based on their impact, with vocabulary being the least influential (mean of 3.33), followed by interest in reading (mean of 3.38), fluency in reading (mean of 3.39), and availability of reading resources as the most influential (mean of 3.44). Further analysis indicated no significant difference in the influence of age on the variables. While sex did not show a significant difference in vocabulary and fluency in reading, it significantly impacted the availability of reading resources. The type of reading materials and frequency of reading did not show significant differences in their influence.Regarding correlation, vocabulary and fluency in reading exhibited low correlations across all variables. Availability and interest in reading also showed low correlations when paired with vocabulary and fluency. Interestingly, an inverse correlation was observed between availability and interest when reciprocated. The most challenging aspect of reading comprehension was identified as the availability of reading resources, as indicated by the highest mean score.In conclusion, this study highlights the need for interventions to enhance the reading attitudes and habits of first-year BEED students, particularly by improving the availability of reading resources to support their reading comprehension.

Influence of Principal-initiated Motivational Speakers Strategy on Academic Achievement of Students in Kenya: A Study across Public Secondary Schools in Mbita Sub County

The use of motivational speakers strategy in enhancing students’ academic achievement in schools in Kenya was adopted by many school administrators in the late 1980s after the introduction of private / holiday tuition in the late 1970s. By 2010, many charismatic professional motivational speakers were commonplace in schools on invitation. Currently many schools are utilising services of motivational speakers. This is based on the premise that worldover research has shown that motivation of the students enhance their academic achievement. There was therefore need to conduct a rigorous study to establish the actual position of this strategy in the 21st Century. Mbita Sub County was selected as the site for the study. This is because  despite the existence of principal-initiated motivational strategy put in place by principals, the Sub-County still performs least with results showing that between 2018 and 2020, the Sub-County was ranked last in Kenya Certificate of Secondary Education (KCSE) examinations compared to the five other neighbouring sub- counties in Homa Bay County. Mbita Sub-County was ranked position five with an average mean score of 4.886 compared to Rangwe which was position one with a mean score of 5.354, Rachuonyo South was second with a mean score of 5.022, Rachuonyo East was third with a mean score of 4.988 while Homa Bay town was fourth with a mean score of 4.958. The objective of the study was to establish the influence of Principal-initiated motivational speakers strategy on students’ academic achievement in public secondary schools in Mbita Sub-County, Kenya. The study established that Principal-initiated motivational speakers strategy significantly influenced students’ academic achievement in public secondary schools by enhancing frequent consultation with teachers.
