RSSI-based fingerprint localization in LoRaWAN networks using CNNs with squeeze and excitation blocks

The ability to offer long-range, high scalability, sustainability, and low-power wireless communication, are the key factors driving the rapid adoption of the LoRaWAN technology in large-scale Internet of Things applications. This situation has created high demand to incorporate location estimation capabilities into large-scale IoT applications to meaningfully interpret physical measurements collected from IoT devices. As a result, research aimed at investigating node localization in LoRaWAN networks is on the rise. The poor localization performance of classical range-based localization approaches in LoRaWAN networks is due to the long-range nature of LoRaWAN and the rich scattering nature of outdoor environments, which affects signal transmission. Because of the ability of fingerprint-based localization methods to effectively learn useful positional information even from noisy RSSI data, this work proposes a fingerprinting-based branched convolutional neural network (CNN) localization method enhanced with squeeze and excitation (SE) blocks to localize a node in LoRaWAN using RSSI data. Results from the experiments conducted to evaluate the performance of the proposed method using a publicly available LoRaWAN dataset prove its effectiveness and robustness in localizing a node with satisfactory results even with a 30% reduction in both the principal component analysis (PCA) variances on the training data and the size of the original sample. A localization accuracy of 284.57 m mean error on the test area was achieved using the Powed data representation, which represents an 8.39% increase in localization accuracy compared to the currently best-performing fingerprint method in the literature, evaluated using the same LoRaWAN dataset.

With the rapid development of internet technology, many industries have embarked on a digital transformation. However, while the Internet has brought convenience to users, it has also become a breeding ground for criminals to commit fraud. On the one hand, a large number of users on the Internet more or less left data, criminals can use this information to practice accurate fraud users, improve the success rate of fraud; On the other hand, online financial transactions such as banking and e-commerce also provide more opportunities for criminals to commit fraud. Therefore, all kinds of fraud methods emerge in an endless flow, through the telephone, information, fishing and other means of fraud, not only to bring hundreds of millions of losses to society every year, but also to the security of people's lives have a huge threat. Monitoring and preventing online fraud is an important part of the cybersecurity industry. For known network fraud, based on the domain name of the phishing site, the account number and mobile phone number that send fraudulent information, simple and effective monitoring and defence can be carried out through the blacklist. However, it is difficult for traditional means to effectively defend against undocumented fraud. With the development of machine learning technology, it is the main research direction of fraud detection methods to discover the information sources and characteristics of information content through machine learning technology, and make real-time and continuous accurate judgments. This paper realises credit fraud detection by generating adversarial network technology, so as to prevent network security risks.

An energy-aware module placement strategy in fog-based healthcare monitoring systems

AbstractFog computing and the Internet of Things (IoT) have revolutionized healthcare monitoring systems, enabling real-time health data collection and transmission while overcoming cloud computing limitations. However, efficiently selecting fog nodes for application modules with varying deadline requirements and ensuring adherence to quality of service (QoS) criteria pose significant challenges due to resource constraints and device limitations. In this paper, we present a novel two-layered hierarchical design for fog devices, leveraging cluster aggregation to optimize the selection of fog nodes for healthcare applications. We introduce three efficient algorithms to minimize system latency and reduce energy consumption in fog computing environments. Our proposed model is rigorously evaluated using the iFogSim toolkit and compared with cloud-based and latency-aware model [Mahmud R, Ramamohanarao K, Buyya R in ACM Transactions on Internet Technology.19, 2018, 10.1145/3186592]. In four distinct network topologies, our model exhibits an average latency reduction of at least 87% and energy consumption reduction of at least 76% when compared to the Cloud-based model. Similarly, when compared to the Latency-aware model proposed in [Mahmud R, Ramamohanarao K, Buyya R in ACM Transactions on Internet Technology. 19, 2018, 10.1145/3186592], our model showcases a minimum reduction of 43% in average latency and 27% in energy consumption. Our contribution lies in addressing the complexity of selecting fog nodes for application modules with diverse deadline requirements, while ensuring QoS. This work advances the field of real-time healthcare monitoring systems, promising substantial improvements in efficiency and effectiveness.

აკადემიური სამეცნიერო კვლევების სფეროსა და არეალის გაფართოება ინფორმაციულ ეპოქაში

The topic refers to the analysis of the current process of expanding the scope and area of scientific research. Internet technologies have changed the political, economic and social reality. Today, security mechanisms became a combined target. The data indicate that the challenges related to unpredictable dangers led to the need to make serious socio-political decisions at all levels, including the need to implement political, legal, economic, military-defense and social measures, to develop new normative regulation systems. Accordingly, cyberspace problems emphasized the role of researchers in various fields of science and expanded the scope and area of academic scientific research. It has become urgent to increase the involvement of Georgian researchers in the ongoing scientific-research processes in this direction. At the same time, there was a need to clarify the use of terms by Georgian researchers in the study of cyberspace problems in the socio-political context. In particular, after the transformation of cyber security as a technical problem into its socio-political task, into cyber security, i.e. when the content of activities changes in order to avoid increased dangers, it is necessary to use the terms in the context of the field of social sciences, as the changes refer not only to activities related to security techniques, but also to human, socio-political activities of society and the state, planning and implementing socio-political events (policy development, concept, planning, etc.). Separation of this problem for research suits the needs of the current situation in social sciences. Accordingly, a specific contribution has been made to the research of strategic assessments of possible trends.

Leveling Up PrEP: Implementation Strategies at System and Structural Levels to Expand PrEP Use in the United States.

Despite highly effective biomedical HIV pre-exposure prophylaxis (PrEP) options, suboptimal PrEP uptake impedes progress towards ending the epidemic in the United States of America (USA). Implementation science bridges what we know works in controlled clinical trial settings to the context and environment in which efficacious tools are intended to be deployed. In this review, we focus on strategies that target PrEP use barriers at the system or structural level, exploring the implications and opportunities in the context of the fragmented USA healthcare system. Task shifting could increase PrEP prescribers, but effectiveness evidence is scarce in the USA, and generally focused in urban settings. Integration of PrEP within existing healthcare infrastructure concentrates related resources, but demonstration projects rarely present the resource implications of redirecting staff. Changing the site of service via expanded telehealth could improve access to more rural populations, though internet connectivity, technology access, and challenges associated with determining biomedical eligibility remain logistical barriers for some of the highest burden communities in the USA. Finally, a tailored care navigation and coordination approach has emerged as a highly effective component of PrEP service provision, attempting to directly modify the system-level determinants of PrEP use experienced by the individual. We highlight recent advances and evidence surrounding task shifting, integration, service delivery, and tailoring. With the exception of tailored care navigation, evidence is mixed, and the downstream impact and sustainability of task shifting and care integration require further attention. To maximize PrEP outcomes, research will need to continue to examine the interplay between individuals, clinics, and the healthcare system and associated policies within which they operate.

The effect of short game videos on consumers' willingness to purchase virtual items in games: A moderating effect based on game experience

With the popularity and development of new media, the short video industry has deeply influenced people's daily shopping behavior and entertainment activities. Similarly, with the development of Internet technology, the game industry is attracting more and more attention from game players and consumers. This study explores the impact of short game videos on gamers' willingness to purchase in-game virtual goods according to the SOR theoretical model and the moderating effect of external stimuli such as consumers' differences in game experience and perceived value on their willingness to buy game virtual products. Through a series of literature research and relevant data analysis and processing, this study confirms that some features of short game videos will not have a significant impact on consumers' purchase behavior, but most features will lead consumers to consume games. Features such as Validity and Serviceability, Interactivity, and Sociability are positively correlated with consumers' willingness on consumption, but Influenceability is not significantly correlated with consumers' willingness to buy. In addition, the game experience of consumers has a significant moderating effect, and the perceived value difference also has an important impact on their purchase behavior. The findings from this study can help the new media industry and the gaming industry to grasp the needs of young consumers, represented by university students, and to adjust their marketing strategies more effectively.

Формування культури безпеки майбутніх фахівців з цифрових технологій як наукова проблема

The article examines the current problem of forming a safety culture of future specialists in digital technologies studying in technical institutions of higher education. An analysis of the conceptual and categorical apparatus of the study was carried out, in particular the terms: computer literacy, cyber literacy, Internet literacy, electronic literacy, information literacy, digital literacy, cyber safety. The latter term has been used by Western scholars who consider it in the context of the use of digital technologies and computers. Therefore, they understand cyber security as the formation of safe behavior in the online environment, based on the responsible use of the Internet and mobile technologies, as well as implemented measures that counteract possible risks. The use of the concept of digital literacy is proposed, as it includes not only the ability to use computer technologies, but also the ability to analyze information in the online environment, taking into account social, cultural, political and educational aspects in one's professional activity.
 The results obtained as a result of the analysis of psychological-pedagogical and methodical literature on the problem of forming a culture of safety in professional activity indicate that, despite certain achievements, this direction has not received conceptual clarity. Currently, even the term "safety culture of professional activity" does not have a scientifically based definition. Theoretical searches indicate the need to clarify its content and structure. In particular, for digital professionals, understanding and implementing a security culture becomes an integral part of their professional development. This involves not only technical skills, but also a deep understanding and internal adaptation of values and approaches that contribute to ensuring cyber security in the modern digital environment on the one hand, and on the other hand - compliance with the requirements for the organization of work in the process of professional activity.

Performance Analysis of G.711 and G.729 Codec Schemes under Various Queuing Techniques in Voice over Internet Protocol Transmissions

Advancements in internet technology have enabled the integration of different traffic types i.e. data, video, and voice into a single network. This technology offers many benefits but also presents some challenges. Real-time traffic services such as VoIP require a certain Quality of Service (QoS) which cannot be guaranteed on the Internet therefore, key performance metrics become all the more important. The choice of codecs and queuing techniques becomes crucial for ensuring optimal performance, especially in networks with diverse traffic types. This research therefore compared the effects of the combinations of these tools (i.e. queuing techniques and codec schemes) on the quality of VoIP. A simulation approach using the OPNET Modeler 14.5 tool has been used to simulate a network supporting three different types of traffic namely: FTP traffic, Video conferencing traffic, and VoIP traffic. While maintaining the same topology and traffic of the network, different types of codec schemes and queuing techniques have been tested through the measurement of parameters such as delay and throughput. The custom Queuing technique showed the best performance overall while FIFO suffered the highest delay. The graphs were observed to follow the same pattern regardless of the codec scheme used however, G729 performed the better of the two as it received higher amounts of voice traffic and slightly lower delays compared to G711.

The digitalization of family life: A multilevel conceptual framework

AbstractThe internet and digital technologies have penetrated all domains of people's lives, and family life is no exception. Despite being a characterizing feature of contemporary family change, the digitalization of family life has yet to be systematically theorized. Against this backdrop, this article develops a multilevel conceptual framework for understanding the digitalization of family life and illustrates the framework by synthesizing state‐of‐the‐art research from multiple disciplines across global contexts. At a micro level, as individuals “do” family online, digitalization influences diverse aspects of family practices, including family formation, functioning, and contact. How individuals “do” family online is not free‐floating but embedded in macro‐level economic, sociocultural, and political systems underpinning processes of digitalization. Bridging the micro–macro divide, family‐focused online communities serve as a pivotal intermediary at the meso level, where people display family life to, and exchange family‐related support with, mostly nonfamily members. Meso‐level online communities are key sites for forming and diffusing collective identities and shared family norms. Bringing together the three levels, the framework also considers cross‐level interrelations to develop a holistic digital ecology of family life. The article concludes by discussing the contributions of the framework to understanding family change and advancing family scholarship in the digital age.
