However, compromise between onboard computation resource allocation and the URLLC requirements becomes challenging since UAVs are limited due to their size, weight, and power, and the virtualization adds extra overhead, which imposes a burden on the conventional Network Functions (NFs). This work proposes a NFV-MEC over UAV model based on Continuous-time Markov Chain (CTMC), with an embedded virtual resource scaling scheme for dynamic resource allocation (DRA). It also extensively analyzes the NFV-MEC architecture's virtualization layer, including node availability and power consumption, besides the URLLC conflicting reliability and latency metrics. The designed model allows analyzing how the main underlying virtualization parameters impact the critical services in a single NFV-MEC over a UAV node, assisting the network operator in proper node dimensioning and configuration.","PeriodicalId":65870,"journal":{"name":"公共管理高层论坛","volume":"11 1","pages":"293-298"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84937607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the radio systems, spatial channel knowledge with the same local accuracy in form of precise Radio Environment Maps (REMs) is beneficial. Constructing REMs with channel measurements is not only costly but often not feasible for specific regions of interest. Consequently, it is necessary to construct REMs based on a limited number of observations. Kriging is typically used for interpolation in the literature. The solely distance-dependent semi-variogram inherently assumes an isotropic environment. However, radio environments, especially indoor, are not isotropic and modeling the directionality of the spatial correlation is not possible by means of a simple variogram function. That is why we propose to enhance the Kriging spatial interpolation by exchanging the semi-variogram model by a Deep Neural Network (DNN) to better describe the anisotropic channel correlations in real-world environments. Ordinary Kriging and our proposed approach are compared for different sampling resolutions and sampling methodologies, namely random and regular. Our proposed method improves the average accuracy and more importantly further increases the confidence in the provided predictions. Higher confidence in the prediction is a way to unlock the usage of such techniques for future communication networks.","PeriodicalId":65870,"journal":{"name":"公共管理高层论坛","volume":"78 1","pages":"54-59"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80845939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cameras and environmental sensors are extensively used to monitor the fish farming sites, and generate huge amounts of data. 5G technology is seen as an enabler to further improve efficiency and digitize the fish farming industry. In this work, the combination of 5G, Device Edge, Cloud and Artificial Intelligence (AI) has been tested to evaluate the benefits and limitations of 5G technology in aquaculture. By emulating a typical Norwe-gian Atlantic salmon farm, remote monitoring, feeding decision support using AI for pellet detection, and 5G performance has been assessed. Peak uplink data rate is the most important key performance indicator, due to the large amount of data produced in the farm itself. To reduce the uplink requirements, a Device Edge has been deployed for running AI-driven pellet detection. Results show that operating full video coverage both underwater and for surveillance clearly exceeds the offered uplink data rate of a typical 5G base station operating in the C-band. Video compression can only be used to a mild extent, due to early deterioration of the pellet detection precision. Therefore, the use of a Device Edge to avoid uplink transmission of the video streams seems to be a better solution. Latency has not been critical in the scenario investigated, however introduction of remote control of cameras and feed provision might change this.","PeriodicalId":65870,"journal":{"name":"公共管理高层论坛","volume":"1 1","pages":"520-525"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82975503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that modern Internet of Things (IoT) and Industry 4.0 5G use cases both require exceptional network speed coupled with security, the choice of security algorithms is a critical element. This paper offers a live 5G testbed setup and methodology to analyze measured round trip times between a user device and a 5G network-in-a-box using the four native 128-bit ciphering algorithms as specified by current Third Generation Partnership Project (3GPP) telecommunications standards. We perform these tests using the Amarisoft AMARI Callbox Mini, a 3GPP-compliant 5G network. Our initial findings show there is no statistically significant relationship between enabled ciphering algorithms and latency given one user device and the 5G network core within the Amarisoft 5G ecosystem, though our setup and methodology allow for expanding this research with multiple devices and longer experiment durations to understand how to best balance network latency and security requirements in a complex wireless network.","PeriodicalId":65870,"journal":{"name":"公共管理高层论坛","volume":"38 1","pages":"532-537"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75807642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, we provide an analytical framework of a RIS-assisted multi-user downlink system where the base station (BS) transmits a superimposed signal to multiple users with the aid of a RIS using non-orthogonal multiple access (NOMA) and rate splitting multiple access (RSMA) transmission technique. First, we discuss the statistical characteristics and evaluate the probability density function (PDF) of the different channels involved in the transmission. We then evaluate the system performance utilizing the PDF and obtain the analytical expressions of the outage probability through the application of NOMA and RSMA transmission techniques and verify the preciseness of the derived closed-form expressions using Monte-Carlo (MC) simulations. Moreover, to gain some useful insights about the system, we also highlight the impact of transmit power availability at the BS, imperfect channel state information (CSI) on the outage probability of each user, effect of number of RIS elements on outage probability. Lastly, we demonstrate the superiority of RSMA over NOMA on the performance of the system.","PeriodicalId":65870,"journal":{"name":"公共管理高层论坛","volume":"93 1","pages":"162-167"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85852170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The National Institute of Standards and Technology (NIST) selected post-quantum digital signature algorithms for standardization. To prepare for the transition to PQC, we study the feasibility of integrating the NIST-standardized PQC digital signatures into the existing networking protocols, which include TCP/TLS and the more advanced QUIC. We study the behavior and performances of implementing PQC signatures for HTTP networking built on TCP/TLS and QUIC. Our experiment-based studies use remote cloud servers across the globe to simulate and measure the real-world networking behaviors. Focusing on the post-quantum lattice-based ciphers of Dilithium and Falcon, our results show that QUIC generally outperforms TCP/TLS (by 52% with RSA, 2.5% or greater with Dilithium algorithms, and 32.8 % or greater with Falcon algorithms). Based on the QUIC performances and the protocol handshake duration overhead between the client and the cloud server, we recommend Falcon for the QUIC-based networking applications for quicker handshake and less variance if the devices can afford the hardware for floating-point-based operations.","PeriodicalId":65870,"journal":{"name":"公共管理高层论坛","volume":"118 1","pages":"573-578"},"PeriodicalIF":0.0,"publicationDate":"2023-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86202459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
