“…It is advantageous that this aggregation improves throughput, reducing on latency especially where the network infrastructure supports voluminous data packets. However, the aggregation may also introduce challenges in managing packets, due the packets large number which in result may affect performance in some network architecture [92] - [95]. Consider a situation whereby large packet encounters errors or needs re-transmission, the entire packet needs to be resent, causing delays; some devices might not have enough buffer space to handle large packets, leading to congestion and delays.…”

The network interface layer of the TCP/IP protocol suite, primarily comprised of the Internet Protocol (IP), serves as the backbone of modern internet communication. With its efficient data delivery, The network interface layer, presents key challenges in terms of performance, security, and privacy. This comprehensive survey delves into these three crucial aspects, analyzing the inherent vulnerabilities, limitations of the interface layer, and provide solutions of the related problems. The performance analysis explores throughput, latency, and bandwidth constraints, along with solutions such as bandwidth allocation and optimization techniques. Vulnerabilities within Network Interface Layer, including denial-of-service attacks and MAC address spoofing, are discussed, along with a review of existing security mechanisms. Privacy flaws are examined, covering MAC address tracking, profiling risks, and anonymization techniques, while also addressing privacy considerations on the Internet of Things. The survey analyzes several case studies providing comparative analysis of the network interface layer protocols, with support of the real world scenarios including performance analysis in high density environment, and security and privacy risks in smart homes networks. The findings provide a comprehensive understanding of the complexities surrounding performance, security, and privacy issues future directions and potential solutions.

Surveys performed among the residents of Zabrze indicate that in 2021 the majority of respondents (67%), wishing to use public services provided by the local government, still preferred to visit the office in person. Residents noticed negative aspects of direct service, such as queues of people waiting for the case to be completed (26%), excessive bureaucracy (24%) or lack of parking spaces (18%). However, they counted on help in completing the necessary formalities by officials who should be: professional (20%), communicative (18%) and kind (17%). The use of the digital platform (ePUAP) dedicated to customer service was reported by 32% of respondents. At the same time, as much as 40% of the respondents, in order to save time and to simplify procedures, declared their will to use innovative methods of remote contact with public administration (e.g. via social media). The COVID-19 pandemic showed that it was possible to increase (even by 250%) the number of cases handled remotely, which with over 90% of households in Poland with access to a computer network creates opportunities for integrated development as part of the Smart City idea. The aim of the paper was to identify the residents’ expectations related to the provision of public services by local administration. Precise determination of the ways of perception of both direct and remote customer service has not only an application value. It also allows for further research study on the management of local government, including the organization of management control, as well as social communication of local governments.

In this study, we have developed a high-precision ultrasonic water flow meter with a 0.18 µm standard CMOS technology. Three methods are proposed to improve the performance: implementation of an active bandpass filter, threshold voltage optimization, and integration of a multi-phase time-zooming technique. The active bandpass filter effectively reduces noise in the received signal, thereby contributing to the overall accuracy of propagation measurements. Based on a threshold voltage generator, our proposed system identifies the optimum threshold voltage, ensuring robust noise durability. Furthermore, we have extended the conventional time-zooming technique by incorporating multiple phases of internal clocks. This innovative multiphase time-zooming technique offers a theoretical improvement in time resolution. The results demonstrate a remarkable suppression of flow rate measurement variations, achieving an impressive reduction to 1/10th of the original values. This affirms the effectiveness of the developed ultrasonic water flow meter in ensuring precise and reliable flow rate measurements.
