However, when multiple drones are deployed, the SIR (Signal-to-Interference Ratio) is degraded by the ground reflection in the environment where UL (UpLink) and DL (DownLink) concurrently exist. In this paper, circular polarization, whose polarization plane characteristics change before and after the ground reflection, is applied to the communication link between the drone and the user to improve the SIR. Numerical evaluation shows the effectiveness of the proposed method.","PeriodicalId":318542,"journal":{"name":"2021 Twelfth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128507072","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 solve this problem, various studies such as dual system construction and multi-pass are being conducted. However, problems such as cost increase and the occurrence of blockage areas remain issues to be resolved. To solve this problem, in this paper, we intend to apply the IAB (Integrated Access and Backhaul) technology discussed in The 3rd Generation Partnership Project (3GPP) standard to the railway wireless communication network. By installing an IAB node in an area where communication failure is expected, it is possible to provide a stable train communication environment by supplementing the communication failure problem through relay communication between the train and the IAB node.","PeriodicalId":318542,"journal":{"name":"2021 Twelfth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130708363","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 smart spectrum, a database is constructed based on the measured data of the radio environment to manage the spectrum, thus realizing highly efficient spectrum utilization, and its usefulness has been confirmed in several systems. On the other hand, for 5G NR signals, the database based on the smart spectrum has not been studied and its usefulness has not been confirmed. In particular, since 5G millimeter wave (mmWave) signals adopt beamforming technology, it is necessary to estimate the directivity and propagation characteristics of multiple beams. Therefore, in the database construction, we need to measure and manage not only the conventional management for each base station and frequency but also each beam. In this paper, we conduct a measurement campaign of mmWave signals from a local 5G base station in Imabari City, Ehime Prefecture, Japan, and construct a spectrum database. We also discuss the analysis results of mmWave signals based on the constructed database, including the radio propagation of each beam and the comparison with anchor band signals. and confirm the usefulness.","PeriodicalId":318542,"journal":{"name":"2021 Twelfth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124488956","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}

Especially object detection and classification are primarily dependent on vision sensors. However, under poor lighting conditions, dazzling sunlight, or bad weathers an object might be difficult to be identified with general vision sensors. In this paper, we propose a sensor fusion system with a thermal infrared camera and LiDAR sensor that can reliably detect and identify objects even in environments where visibility is poor, such as in severe glare and fog or smoke. The proposed method obtains intrinsic parameters by calibrating the thermal infrared camera and LiDAR sensor. Extrinsic calibration algorithm between two sensors is made to obtain the extrinsic parameters (rotation and translation matrix) using 3D calibration targets. This system and proposed algorithm show that it can reliably detect and identify objects even in hard visibility environments, such as in severe glare due to direct sunlight or headlights or in low visibility environments, such as in severe fog or smoke.","PeriodicalId":318542,"journal":{"name":"2021 Twelfth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125460703","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 allocate resources to EDs, LoRaWAN utilizes an energy-efficient adaptive data rate (ADR), which is recommended for static applications. Recently, Semtech suggests using a blind ADR (BADR) to increase geographical coverage with enhanced battery life for mobile applications, such as pet-tracking. The BADR utilizes three spreading factors (SFs): SF 12 (one time), SF 10 (twice), and SF 7 (three times) every hour. This study aims to analyze and provide insights into the potential and limits of the BADR. Simulation results show that both ADRs suffer from high packet loss and excessive energy consumption in confirmed and unconfirmed modes. However, BADR is observed outperforming the ADR.","PeriodicalId":318542,"journal":{"name":"2021 Twelfth International Conference on Ubiquitous and Future Networks (ICUFN)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130456557","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 paper, we propose a stable matching-based DMM-GW selection scheme considering the preferences of both DMM-GWs (w.r.t. load balancing) and MNs (w.r.t. location update cost).

This framework combines two robust technologies of our time healthcare IoT (HIoT) and blockchain technology to help creating secure patient diagnosis just like a classical medical report but digitally like an E-health card. Through this model, patients can wear the IoT healthy pi kit device to measure their vitals' information.
