ChessCrypt: enhancing wireless communication security in smart cities through dynamically generated S-Box with chess-based nonlinearity.

In the contemporary landscape of smart cities, ensuring the security and confidentiality of transmitted data has become paramount. The proliferation of Internet of Things (IoT) devices, mobile communication platforms, and wireless sensor networks has magnified the need for robust cryptographic solutions to safeguard sensitive information from malicious adversaries. In response to these challenges, we introduce ChessCrypt-a novel approach to enhancing wireless communication security through the development of a new S-Box algorithm inspired by the nonlinear movement patterns of chess pieces. ChessCrypt leverages the dynamic and unpredictable nature of chess piece movements, namely knights, kings, and bishops, to introduce a high degree of nonlinearity and confusion into the encryption process. By incorporating elements of randomness and unpredictability, our proposed S-Box algorithm offers robust protection against a wide range of cyber threats, including eavesdropping, data interception, and cryptographic attacks. We demonstrate the effectiveness and resilience of ChessCrypt through rigorous testing and analysis, showcasing its superiority over traditional cryptographic methods in enhancing the security of wireless communication networks. Our results underscore the significance of ChessCrypt as a promising solution for fortifying wireless communication security in an increasingly interconnected world of ours.

Exploring sources of patient dissatisfaction in mobile health communication: A text analysis based on structural topic model.

Understanding online patient dissatisfaction is essential for improving the quality of healthcare services, patient satisfaction, and physician career development. This study is the first to apply the structural topic model to patient satisfaction research based on patient online reviews from a mobile health communication platform, revealing eight negative topics of patient concerns. These topics include under-explored areas such as "go to the hospital for check-ups," "incomplete counseling," and "language expression." Additionally, we incorporated the doctor's title as a covariate in the model to examine how specific topics varied across different conditions. The results indicated that higher-titled doctors were more likely to receive complaints about the cost of treatment and whether the question was answered, whereas lower-titled doctors were more likely to receive complaints related to physician's knowledge, incomplete counseling, and response speed. This study not only enhances our understanding of mobile health services but also provides targeted insights for healthcare providers to improve their services, thereby contributing to the advancement of patient-centered care.

Determining influence of service quality on user identification, belongingness, and satisfaction on mobile social media: Insight from emotional attachment perspective

WeChat has burgeoned into a predominant mobile communication platform that facilitates instantaneous text and voice-mediated dialogues. Currently, it stands out as a quintessential mobile social media platform in mainland China. The primary objective of this study is to meticulously dissect the ramifications of entire service quality on user assessments of WeChat, encompassing facets such as user satisfaction, identification, belongingness, and perceived benefit, whilst unraveling the correlation between user assessments and their proclivity towards emotional and service attachment. This scholarly endeavor is amongst the scant researches that empirically scrutinize the intricate interplay between entire service quality, user evaluations, emotional attachment specific to WeChat, and overarching service attachment within the mobile social media milieu. The research paradigm was rigorously evaluated through the harnessing of data collected from the Sojump database, which contains 598 valid observational data points. Employing the robust methodology of structural equation modeling, the research model was subsequently corroborated and authenticated. Obtained results validate the path effects, demonstrating that entire service quality exerts a positive influence on WeChat users’ identification, belongingness, satisfaction and benefit. Furthermore, emotional attachment significantly contributes to service attachment. Based on attachment theory, the revelations from this study shed light on the profound mechanisms through which entire service quality in mobile social media can invigorate and solidify user evaluations, fortifying their predisposition towards sustained product and service affiliations.

FANET management process simulation at the deployment and operation stage

The object of the study is the process of managing the air network of air communication platforms of the FANET class (Flying Ad-Hoc Network), which is a component of the ground-air communication network, and which is performed on rotary unmanned aerial vehicles (UAVs) of the mini class, at the stage of deployment and operational management. The scientific research is aimed at the managing process formalization of aerial communication platforms of the air communication network in the implementation of two classes of management tasks – the class of traffic management tasks and the class of communication tasks. The analysis of this subject area showed that the management tasks at the stage of deployment and operational management of the air subnet are a multi-parameter optimization task and require the formation of control solutions at the OSI physical, channel and network levels, open systems interaction model. Tasks related to the adaptive management of radio coverage in zones (geographic areas of the area), including the clustering of terrestrial subscribers (communication nodes), were not considered, and relate to processes at the transport and application levels. At the same time, the article shows the mathematical apparatus of the approach to the compensation of the deviations of the trajectory of an unmanned aerial vehicle (UAV) in the conditions of a directional obstacle, which will allow the formation of control solutions for adaptive control, directional patterns at the output of the transmission path. Such compensation is carried out using methods of algorithmic exchange of probes (messages) between the mobile base station and communication platforms with a certain periodicity – solutions at the channel and network levels, as well as the use of Multi User MIMO technologies. This technology allows for information exchange with several client devices at the same time, and not sequentially, sending probes to several spacecraft on one channel, using several transmitting and receiving antennas, and the calculation of channel coefficients allows to estimate the azimuthal angle of deviation and the angle of elevation.

Examining the Effects of Mobile Telephone Communication on the Utilization of Antenatal Care Services Among Expectant Mothers in Kyotera And Rakai Districts, Uganda

Uganda still grapples with a high maternal mortality rates of 336 deaths per 100,000. Expectant mothers across the country lack awareness about the availability of antenatal care services; yet attendance of antenatal care services during pregnancy is crucial in protecting the health of women and unborn children. This article describes a protocol for investigating the effectiveness of mobile telephone communication interventions on the utilization of antenatal care services among expectant mothers in the districts of Kyotera and Rakai Districts in Uganda. Under the protocol, 28 health facilities in the districts of Kyotera and Rakai will be selected using simple random sampling and allocated into the intervention and control arms at a ratio of 1:1. A total of 2224 expectant mothers receiving antenatal care from the sampled health facilities will be recruited using systematic sampling. Expectant mothers receiving antenatal care from facilities allocated into the intervention arm will receive mobile telephone voice and text messages reminders for scheduled ANC visits. The mobile telephone messages will further provide maternal health information and availability of ANC services on a fortnightly basis. On the other hand, expectant mothers receiving antenatal care from facilities allocated into the control group will not get any reminders for scheduled ANC visit and maternal health information through the mobile telephone communication platform. Expectant mothers in the control arm will receive standard maternal health care without reminders. Expectant mothers in both groups will provide baseline data, midterm data will be obtained from the ANC registers at 6 moths while end of term data will be collected after an intervention period of 12months. The data collected will include the number of antenatal care visits attended, antenatal care services obtained from the health facilities, sociodemographic factors and mobile telephone usage, ownership and knowledge. The anticipated outcomes are; increased awareness and utilization of ANC services.

Positive Demand Spillover of Popular App Adoption: Implications for Platform Owners’ Management of Complements

As platform owners interact with end users and complementors, their demand-side characteristics and performance affect the overall value creation of ecosystems. This research investigated how the emergence of popular complements on a mobile communication platform impacts the usage of other complements by the platform’s end users and how platform owners can benefit from such demand spillovers. Using individual user-level app usage data, we empirically demonstrated how the presence of a popular app alters the demand structure of a platform through changes in the usage of other apps operating within it. The findings reveal that popular app adoption by users increases the app usage, excluding the usage of popular apps, only within the platform offering a popular app, supporting the existence of positive spillovers from popular complement adoption on a platform. Such positive within-platform spillovers occur through the increased usage of both existing and new apps, with stronger positive spillovers for new apps. These findings imply that platform owners can reap benefits by coordinating the launch of new complements and the promotion of less-known counterparts to end users with the emergence of a popular app. All these results shed light on how platform owners can manage their complements and create value from popular complements.

Manufacturing Digitalized Soft Propaganda: Practices of the Chinese Party Newspapers in the Past Decade

ABSTRACT This article analyzes the practices of the Chinese party newspapers’ propaganda in the past decade. Through in-depth interviews with 30 journalists and editors of 12 party newspapers and analysis of investigative reports about 43 party newspapers’ propaganda work, this article finds that the party newspapers mainly used three propaganda strategies. Among them, mobile first is a technical strategy that gives priority to the use of mobile communication platforms and technologies in the whole process of news production and dissemination; digitalizing authoritative and localized information is a content strategy that aims to increase the appeal of party newspapers’ content to the citizens; and diversified outsourcing, as a service strategy that provides a series of services to the citizens on behalf of government departments, is an innovation of the propaganda practice of the party newspapers. However, there exists a gap in the performance of party newspapers at different levels in the actual propaganda work, and some of them engage in the practice just for the sake of formality.

Interactive Cultural Communication Effect in VR Space of Intelligent Mobile Communication Network

Virtual reality technology can provide more display techniques to realize the interactive design of multiexhibition area of red humanities and natural resources. First of all, through the three-dimensional interactive display of cultural relics and scene reproduction of historical events, visitors can enjoy the unrestrained and immersive appreciation, make up for people’s lack of understanding of history, and let tourists personally feel the difficulties and hardships in the development of Chinese revolutionary history. Second, the digital method also provides for the pavilion and the scenic spot design personnel more creative method; dynamic scene reappearance interaction design based on virtual reality technology to promote education, protection of cultural relic collection and utilization, academic research, and the industrial development and multidimensional public welfare publicity results is blended in among them, through the panoramic, immersive, and interactive display technique, such as multilevel multiway spread red brigade culture. Virtual reality constantly imitates the real-life environment, and the application of perception sensing equipment has perception. This new technology requires us to continue to explore and research it. Virtual reality technology is a very cutting-edge subject and research field, which is very challenging. The communication form of culture has also been constantly evolving. Virtual reality technology (VR) has changed the way of traditional culture appreciation through the transmission of visual information, bringing people a new aesthetic enjoyment. Mainstream media is used to mobilize the red cultural heritage protection and scholars at home and abroad, to explore the application of virtual reality in the red culture tourist attraction planning, and to explore virtual reality applications in red open spot virtual roaming: exploration of virtual reality in the application of historical and cultural sites to red tourism management and exploration of virtual reality in the brand historical and cultural sites in the application of the travel marketing, to build an intelligent mobile communication network communication platform and broaden the new path of inheritance and protection. On the basis of studying the communication effect of traditional culture, this paper studies the possible communication effect of symphony orchestra under the new technology format under the framework of communication studies. It also analyzes and explores various factors such as the practical value, difficulty, civilized prestige, adaptability, and resistance to adversity of the culture in cultural communication and compares the methods of cultural communication. By developing a virtual instrument placed in the sphere of virtual reality space, the traditional symphony orchestra can be transformed into an interactive culture communication in virtual reality space. In this communication design, users can define their own instruments to play interactive culture communication, change the position of the instrument on the sphere interactively, and even change the sound effect of the symphony interactively by rotating or adjusting the size of the sphere, so as to achieve the best communication effect of the symphony.

Two-Step Dynamic Cell Optimization Algorithm for HAPS Mobile Communications

High altitude platform stations are attracting much attention as novel mobile communication platforms for ultra-wide coverage areas and disaster-resilient networks. Multi-cell configurations can increase communication capacity in a wide area. Conventional work optimizes the cell configuration for a multi-cell configuration based on a genetic algorithm (GA). This method identifies an optimal cell configuration in terms of spectral efficiency depending on the number of cells under a uniform user distribution. However, user distributions differ depending on location; thus, cell configuration optimization is also required for non-uniform user distributions. The problem is an increased number of parameters because each cell requires different antenna parameters for non-user distributions compared to a uniform user distribution. This increases the difficulty of optimization, even when using a GA in some cases. Therefore, We propose a GA-based two-step cell optimization algorithm that comprises both search space reduction and antenna parameter optimization steps to address this problem. The proposed method employs the concept of co-evolution, i.e., a divide-and-conquer method. The proposed method divides multiple cells into several groups to reduce the number of optimized parameters and optimizes each group in order. In addition, the search space is reduced based on a marginal histogram obtained via optimization with a large step size. Simulation results demonstrate that this technique can reduce the number of combinations compared to the case without sub-area division. In addition, there are cases where the search space reduction further reduces the number of combinations without degrading the sum of the square root of throughput.

News or social media? Socio-economic divide of mobile service consumption.

Reliable and timely information on socio-economic status and divides is critical to social and economic research and policing. Novel data sources from mobile communication platforms have enabled new cost-effective approaches and models to investigate social disparity, but their lack of interpretability, accuracy or scale has limited their relevance to date. We investigate the divide in digital mobile service usage with a large dataset of 3.7 billion time-stamped and geo-referenced mobile traffic records in a major European country, and find profound geographical unevenness in mobile service usage—especially on news, e-mail, social media consumption and audio/video streaming. We relate such diversity with income, educational attainment and inequality, and reveal how low-income or low-education areas are more likely to engage in video streaming or social media and less in news consumption, information searching, e-mail or audio streaming. The digital usage gap is so large that we can accurately infer the socio-economic status of a small area or even its Gini coefficient only from aggregated data traffic. Our results make the case for an inexpensive, privacy-preserving, real-time and scalable way to understand the digital usage divide and, in turn, poverty, unemployment or economic growth in our societies through mobile phone data.

War on woodpeckers: 5G, utility poles and the 1918 Migratory Bird Treaty Act

This article uses environmental perspectives as a framework for analysing mobile communication networks, platforms and devices related to fifth generation (5G) expansion. The article focuses on wooden utility poles, recent actions by the Federal Communications Commission (FCC) and contested Department of the Interior (DOI) interpretations of the Migratory Bird Treaty Act of 1918. The pell-mell expansion of 5G and the Internet of Things (IoT), new deregulatory actions allowing for new equipment on utility poles and controversies regarding the 1918 Bird Act absolving corporations from culpability when they kill birds as part of their business activities (oil spills, construction and similar) create a dangerous mix. These new initiatives pose threats to wildlife including when birds, particularly woodpeckers, interact with wooden utility pole infrastructures. The United States of America is the main geographic setting for this study, although these trends are partially evident in many other nations.

Queered online pandemic relationships: Mobile expressions of intimacies, care, and emotion work

Drawing from the assumptions on queer and mobile intimacy, emotion work, and care, this paper explores the role of mobile communication platform access and use among Filipino gay couples who have been physically separated because of the COVID-19 pandemic. The paper looks at in-depth narratives of 24 gay men whose romances have been transferred to and transformed by messaging apps due to the pandemic. The accounts of these gay couples represent the realities of cosmopolitan gay men in negotiating digital romantic presence as they manage connection despite the distance. Mobile technologies have deepened the synchronous and asynchronous rituals of maneuvering romance as couples manage imagined emphatic romances. The participants’ descriptions revealed queered technology-use in bridging and maintaining imagined intimacies while feeling trapped in the dependence on mediated means of enacting such intimacies.
