Our setup consists of a source node communicating with a destination node with the help of a RIS, and under the presence of a malicious passive eavesdropper attempting to overhear the genuine transmission. Furthermore, an external cooperative jammer is incorporated to reinforce the system’s secrecy by broadcasting an artificial noise to disrupt the eavesdropper; such a noise can be removed at the destination. Finally, we assume that the tunable RIS phases based on the channel estimates are subject to quantization errors. By virtue of the well-adopted Gamma and Exponential distributions approximations, an approximate expression for the system’s intercept probability (IP) is derived in terms of the main setup parameters. The results show that the greater the number of reflective elements (REs) and jamming power, the better the secrecy, while the number of quantization bits has less impact when exceeding 3 bits. In particular, an IP of 10−3 can be reached with 50 REs even when the legitimate link’s average signal-to-noise ratio (SNR) is 15 dB below the wiretap channel’s average SNR. Monte Carlo simulations endorse the derived analytical results.","PeriodicalId":114443,"journal":{"name":"2022 International Balkan Conference on Communications and Networking (BalkanCom)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123434194","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 power allocation in a cooperative NOMA system is a challenging task having a significant impact on the user perceived quality of service. In this paper, an adaptive power allocation technique is proposed using Fuzzy Logic (FL) for cooperative NOMA with imperfect successive interference cancellation (SIC). The FL system is trained to provide the power allocation coefficient by systematically varying signal-to-noise ratios (SNRs) at relays and users and randomly assigning all wireless channel coefficients. The power is allocated between the NOMA user pair within a resource block in such a way that the rate fairness is maximized and the system outage is minimized. The numerical results obtained by FL are close to the optimum outage probabilities and rate fairness results for all experiments when the number of relays and SNRs are varied. The results are promising since the computationally efficient FL can be successfully utilized at the run time for allocating power in a cooperative NOMA system.","PeriodicalId":114443,"journal":{"name":"2022 International Balkan Conference on Communications and Networking (BalkanCom)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117111617","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 case that heterogeneous quality of service (QoS) requirements for different users are considered. While planning the trajectory, the coverage area of the UAV-BS and backhaul capacity between the UAV-BS and Ground Base Station (GBS) are limited. Under these constraints, the aim is to find a trajectory for the UAV-BS that maximizes the total data rate provided to the users during the flight using reinforcement learning. With the application of Q-learning in our problem, the UAV-BS learns to take action to achieve the desired goal. As a result of trial and error processes with different learning parameters, appropriate parameters are determined and a reinforcement learning model is trained. Different communication scenarios are compared for analyzing the effects of the constraints. According to the effects of the mentioned constraints and heterogeneous QoS demands, UAV-BS’s trajectory preferences and total transmission rate changes are examined. Three prominent results shows the effects of coverage, backhaul, and heterogeneous QoS. The UAV-BS tends to increase its altitude as the coverage constraint increases. Moreover, the backhaul constraint forces the UAV-BS’s trajectory closer to the GBS. Lastly, UAV-BS takes into account different QoS requirements of users as much as possible. UAV-BS maximizes the total transmission rate by determining the most suitable trajectory to meet these constraints.","PeriodicalId":114443,"journal":{"name":"2022 International Balkan Conference on Communications and Networking (BalkanCom)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128369220","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}

A grand challenge is to provide in-flight connectivity in high altitudes, and particularly in isolated locations, such as the oceans, where establishing an air-to-ground link is not possible. Aeronautical Ad-Hoc Networking (AANET) intends to cope with this challenge by forming a network of airplanes having air-to-air (A2A) connections. However, the dynamic nature of such a network is likely to lead to unstable connections. The primary cause of the majority of these stability issues is known to be poor clustering of aircrafts. Consequently, concentrating on aircraft clustering and making them more stable can improve connection. This paper aims to unveil the benefits of density-based clustering to improve the AANET performance. To do so, the paper employs a multi-feature DBSCAN algorithm for the clustering problem that exploits several features of real flight datasets, including latitude, longitude, altitude, direction, and velocity. Instead of a typical distance metric such as Euclidean or Haversine, the technique produces a precomputed distance matrix and feeds it to DBSCAN. This method also includes a weighted scheme to reflect the relative importance of each component of the distance calculation. Simulations under OMNET++ by using real-time flight data point out that packet delivery ratio and end-to-end latency of the state of the art clustering-based AANET solutions can be improved by 40 % and 30 %, respectively. Furthermore, the proposed method achieves a 20% reduction in cluster changes and the number of clusters.","PeriodicalId":114443,"journal":{"name":"2022 International Balkan Conference on Communications and Networking (BalkanCom)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132211525","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}

Although with the rapid development of the artificial intelligence field, various smart devices and services using deep learning have appeared in the face recognition technology, problems exist, including costs and computational resources to build and apply a recognition model. The purpose of this paper is to develop a facial identification system using the pre-trained model and spoken dialogue agent. Our key ideas include automatic training data generation by spoken dialogue between the user and the agent and the acquisition and comparison of facial features using a pre-trained model. In this way, our face identification system can be easier introduced and expected with only a general-purpose computer and a Web camera, without needing a conventional Internet connection and manual labeling of training data.","PeriodicalId":114443,"journal":{"name":"2022 International Balkan Conference on Communications and Networking (BalkanCom)","volume":"557 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116268699","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}
