Efficient and Secure Data Transmission Approach in Cloud-MANET-IoT Integrated Framework

The Internet of Things (IoT) devices have the capabilities to interact and communicate in 5G heterogeneous networks. They also have the capabilities to form a network with neighborhood devices without a centralized approach. This network is called the mobile ad hoc network (MANET). Through an infrastructure-less system of the Internet of Things environment, the MANET enables IoT nodes to interact with one another. Those IoT nodes could interactively connect, communicate as well as share knowledge between several nodes. The role of cloud throughout this structure is to store as well as interpret information through IoT nodes. The communication security has been introduced as one of the techniques to solve the data transmission security issue that could result in increased performance in cloud consumption and ubiquity. The purpose of this research is to establish a communication system among IoT nodes in an embedded Cloud and MANET structure. Aiming to create an efficient and secure approach for communication in Cloud-MANET-IoT integrated framework, this approach has been implemented and tested

Smart Contracts to Support the Advancement of Blockchain Technology in the Security Integrity

The development of technology today is used as a benchmark in the advancement of the industrial world where the development of technology has influenced various aspects in the life of today's society. Smart contracts as one form of blockchain technology that resembles a conventional contract can be used to bind agreements between one party and another. One difference between a smart contract and a conventional contract is the smart contract that is stored in the blockchain. With the presence of smart contracts on the blockchain has become one of the most sought-after technologies, because the number of users is high enough for each transaction within the company. In this case various features of smart contracts applications in various worlds, ranging from financial services, life sciences, energy resources and media voting. Smart contracts still pose a lot of challenges that overwhelm the interaction of some Parties, such as users, developers, and organizations built on smart contracts. Smart contracts are essentially a very effective source of problem solvers, where smart contracts on the blockchain make it easy to maintain data security, and save costs and time. In addition, in the absence of third parties strongly minimizes the fraud that is often done by irresponsible parties, this prevents conflicts between parties. Prone to cases of loss of a document is generated because there is no secure storage media. The advent of smart contracts on the blockchain is expected to be a solution to tackle most of the world's commercial and bureaucratic systems. &nbsp

Extracting class diagram from hidden dependencies in data set

A conceptual model is a high-level, graphical representation of a specic do-main, presenting its key concepts and relationships between them. In particular, these dependencies can be inferred from concepts' instances being a part of big raw data les. The paper aims to propose a method for constructing a conceptual model from data frames encompassed in data les. The result is presented in the form of a class diagram. The method is explained with several examples and veried by a case study in which the real data sets are processed. It can also be applied for checking the quality of the data set

The results of this study, AI make educational games more interesting and interactive for children

A qualitative study on best practices and process of eliciting unambiguous quality attributes in scrum-based projects

Software quality is very crucial for users’ satisfaction and software success in the market. Recent studies found some ambiguous software quality attributes that may lead to low-quality software, and lack of elicitation practices in projects that apply Agile Software Development (ASD) methodology especially Scrum. However, current ASD methodologies, systematic literature reviews and surveys did not provide explanation of the necessary elicitation practices. Therefore, this qualitative study was essential to achieve two objectives: exploring the best practices and identifying process of eliciting unambiguous quality attributes in Scrum-based projects. The study used qualitative approach in which data was collected via interviewing eight experienced software practitioners from India and documents analysis that explains documentation of quality attributes in Scrum. For data analysis, the thematic analysis method was used for analysing interviews scripts and documents. The findings resulted in three initial themes that represent three steps in the elicitation process and six sub-themes that represent the elicitation practices. The first step is proactive exposure to quality attributes which consists of two practices: understanding software scope and envisaging potential quality attributes. The second step is mutual learning discussion which consists of two practices: ameliorating technical knowledge of customers and users and compiling details of quality attributes. The third step is verifying common understanding which consists of two practices: utilization of visual artefacts and documentation of quality attributes. The contribution of the study provides an extension to ASD body of knowledge regarding the effectiveness of disambiguation of terminologies in software domain, simplifying technical terms, representing reusable software artefacts, showing similar software, drawing mock-up and developing proof of concept in eliciting unambiguous quality attributes. Furthermore, the findings accentuate practical contributions to the software developers such as reducing effort, time and cost of designing and construction of software

SMALL TOURISM BUSINESS SURVIVAL IN THE EASTERN CARIBBEAN

This study investigates the role of strategic approaches in the survival of small tourism businesses in the Eastern Caribbean, focusing specifically on Antigua and Barbuda, Dominica, and St. Lucia. Despite the acknowledged significance of strategic management in fostering business growth and longevity, scant attention has been given to traditional strategic approaches within small tourism enterprises in developing economies heavily reliant on tourism. The Caribbean, renowned for its diverse and attractive tourism offerings, remains a hotbed for multinational tourism corporations, yet the impact of small businesses within this economic landscape remains understudied. Drawing from an exploratory sequential mixed methods design, the study combines qualitative interviews with 31 participants and a survey of 217 small tourism businesses to elucidate the internal and external factors influencing survival and explore specific strategic approaches employed by these enterprises. Findings reveal five validated factors—low season impact, peak and off-peak dynamics, strategic closure, management, and survival—identified through a newly developed measuring instrument (SIDE). Contrary to prevailing assumptions, the study concludes that strategic approaches do not significantly contribute to small tourism business survival in the Eastern Caribbean. External challenges such as political influences, networking constraints, competition, and seasonality, alongside internal obstacles like employee deviance, emerge as critical barriers to survival. These findings underline the intense business environment faced by small tourism enterprises in developing economies reliant on tourism, urging scholars and policymakers to consider these dynamics in future research and decision-making processes. While the research provides a theoretical foundation for understanding survival dynamics, it acknowledges the existence of additional factors shaping small tourism business survival within the dynamic tourism industry, emphasizing the need for future studies to explore these dimensions comprehensively
