This paper introduces a study done to evaluate the use of machine learning regression techniques to predict the link quality of communications done by IoT nodes. The proposed methodology is able to predict the link quality of the most typical cloud communication protocols, such as cellular, Wi-Fi, SigFox and LoRaWAN, based on the node location. To discover the best model to achieve this, a set of machine learning techniques were implemented, including Linear Regression, Decision Tree, Random Forest and Neural Networks, being the results compared. Results showed that Decisions Trees achieve the best efficiency, with a margin of error of 7.172 dBm, after cross-validation. This paper includes a detailed description of the methodology, its implementation and the experimental results.

Security and safeness are constant topics to be solved in cities around the world, finding ways to detect weapons threatening human beings is an important challenge. This paper presents an approach for solving knife detection in Close Circuit Television (CCTV) cameras videos. In this sense, knife detection is the goal in this work and through a combination of color and invariant moments techniques, the system presented reaches the objective and turns reliable in indoor environments, with or without environmental illumination. The work has been proved under white and infrared lighting, with a range between 0.5 to 4.0 meters of distance from camera to knives with positive qualities of detection. Supporting this work, videos were uploaded on web. The reported error in them runs from 0% to 1.192%. This system may be useful at convenience stores, banks, theatres and some others public places with commercial surveillance cameras from a relatively long distance. Results offer a simple classification because to important features found. For instance, when the system may be executed by parallel processors or in pipeline method it could be detecting more than one knife on scene.

In this research we focus on how to prevent Double Spending Attack (also called 51 % hash rate attack), a particular security issue related to blockchain technology in the current cryptocurrency world. We describe the main idea of our proposed Block Access Restriction (BAR) mechanism, which controls the actual block requests and detects malicious behaviors while transactions have been recorded into a specific block, to protect general miner's privileges and provide fairness in the blockchain network environment. We propose an effective way to prevent this to happen (with detailed steps), discuss how to deploy BAR switch into blockchain networks and how the BAR switch can prevent DSA while the hacker bypasses it. We also present general idea of implementing BAR switch, and point out the importance of dealing with security threat at post-quantum computing era.
在这项研究中,我们重点关注如何防止双重支出攻击(也称为51%哈希率攻击),这是当前加密货币世界中与区块链技术相关的一个特定安全问题。我们描述了我们提出的块访问限制(BAR)机制的主要思想,该机制控制实际的块请求,并在交易被记录到特定块中时检测恶意行为,以保护一般矿工的特权并在区块链网络环境中提供公平。我们提出了一种有效的方法来防止这种情况的发生(有详细的步骤),讨论了如何将BAR交换机部署到区块链网络中,以及BAR交换机如何在黑客绕过它时防止DSA。提出了实现BAR交换的总体思路,并指出了处理后量子计算时代安全威胁的重要性。

There has been a huge growth in the number of mobile devices in the last few years. These mobile devices are equipped with various hardware that allows them to sense and receive different types of wireless signals such as Global Positioning System (GPS), Wi-Fi, Bluetooth, and others. Today, a mobile device is capable of obtaining its location in various ways. Location-enabled mobile devices enable applications to utilize and verify users' location to allow them to access location-based resources, which is known as Location-based access control (LBAC). The implementation of LBAC has grown rapidly with the increase in the number of mobile devices and location-based services (LBS) and is expected to grow more in the future. LBAC verifies the user's location is required. User location can be obtained using different localization techniques. In this paper, we survey the localization techniques used in LBAC. Consequently, we examine and review the strength and weaknesses of each of the localization techniques. Finally, we discuss the nature of applications that suits each localization technique the most.

The current work in this paper inspired by the concepts of Edge Computing, Machine Learning, Computer Vision and Internet of Things (IoT). This synergy is used for monitoring apple orchard yield and more specific the detection and information extraction for apple harvesting purposes in the agriculture field. The above concept utilizes the means for a low power information relay using LoRaWAN (Low Power Wide Area Network) protocol designed to connect battery operated “things” with the internet in regional or global topology. Image acquisition and data are processed on a battery driven edge device away from the grid and on site. The proposition implementing a full YoloV4 framework in a single board computer (SBC) equipped with a proper camera and by using custom-trained weights seems to be a feasible solution. The performance of the proposed approach for good apple detection is up to 66.89% for complex dense environments. These preliminary results reveal the feasibility of this edge computing approach utilizing Artificial Intelligence and IoT technologies.
本文目前的工作受到边缘计算、机器学习、计算机视觉和物联网(IoT)概念的启发。这种协同作用用于监测苹果园产量,更具体地说,用于农业领域苹果收获目的的检测和信息提取。上述概念利用低功耗信息中继的手段,使用LoRaWAN(低功耗广域网)协议,旨在将电池操作的“事物”与区域或全球拓扑中的互联网连接起来。图像采集和数据在远离电网的电池驱动的边缘设备上进行处理。在配备适当摄像机并使用定制训练权重的单板计算机(SBC)中实现完整的YoloV4框架的提议似乎是一个可行的解决方案。在复杂的密集环境中,该方法的苹果检测性能高达66.89%。这些初步结果揭示了利用人工智能和物联网技术的这种边缘计算方法的可行性。

Throughout the COVID-19 pandemic, one of the largest goals has been to social distance while still finding ways to continue our daily lives in a somewhat normal manner. Many businesses and institutions need ways to account for their attendees on a daily basis, but COVID-19 has created a rift in some of the normal ways that this can be done while abiding by social distancing rules and maintaining proper sanitation of objects and devices. In this study, we propose a zero-effort and zero-interaction approach, especially for being in the midst of a pandemic, as well as a probable solution for well beyond the pandemic due to this system's ease of use. This paper utilizes a Wi-Fi-enabled device (e.g., smartphone) and access points to calculate a user's location within a building and account for its activeness to consider a user's social distancing or not. The proposed scheme completely eliminates the necessity to have face-to-face interaction or physical contact with a person or a device.
在2019冠状病毒病大流行期间,最大的目标之一是保持社交距离,同时仍能以正常的方式继续我们的日常生活。许多企业和机构需要每天为他们的与会者负责,但COVID-19在一些正常的方式上造成了裂痕,这些方式可以在遵守社交距离规则和保持物体和设备的适当卫生的同时实现。在这项研究中,我们提出了一种零努力、零互动的方法,特别是在大流行期间,由于该系统的易用性,它也可能是大流行之后的一种解决方案。本文利用具有wi - fi功能的设备(例如智能手机)和接入点来计算用户在建筑物内的位置,并考虑其是否考虑用户的社交距离的活跃度。所提出的方案完全消除了与人或设备进行面对面互动或身体接触的必要性。

Many businesses and institutions need ways to account for their attendees on a daily basis, but COVID-19 has created a rift in some of the normal ways that this can be done while abiding by social distancing rules and maintaining proper sanitation of objects and devices. In this study, we propose a zero-effort and zero-interaction approach, especially for being in the midst of a pandemic, as well as a probable solution for well beyond the pandemic due to this system's ease of use. This paper utilizes a Wi-Fi-enabled device (e.g., smartphone) and access points to calculate a user's location within a building and account for its activeness to consider a user's social distancing or not. The proposed scheme completely eliminates the necessity to have face-to-face interaction or physical contact with a person or a device.","PeriodicalId":443405,"journal":{"name":"2021 IEEE World AI IoT Congress (AIIoT)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128609563","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 current world, technology innovation is developing day by day which makes people's life easier and more comfortable. Nowadays, nearly every work of a computer and many features are presently empowered in a mobile application. To move in the city, it is quite expensive when people use transport privately but if it is possible to share, then the cost of transportation will decrease at least half or less than half. This paper presents an android application that works collectively using Google APIs and maps. This is a ride-sharing app. Users with the same destination will be able to share rides with others who are of the same place to reach. The application will calculate their fares. A database is used to store the records of registered users. By using the android based platform, application would be optimized for any usage. For the applications, efficient offline and online algorithms have been presented. An algorithm with theoretical analysis and trace-driven simulations under practical settings has been verified.
在当今世界,技术创新日益发展,使人们的生活更轻松,更舒适。如今,几乎电脑的每一项工作和许多功能都可以在移动应用程序中实现。在城市里,人们使用私人交通工具是相当昂贵的,但如果可以共享,那么交通成本将减少至少一半或不到一半。本文介绍了一个使用Google api和地图共同工作的android应用程序。这是一款拼车应用。有相同目的地的用户可以和其他有相同目的地的人拼车。应用程序将计算他们的车费。数据库用于存储注册用户的记录。通过使用基于android的平台,应用程序将针对任何用途进行优化。在应用方面,提出了高效的离线和在线算法。通过理论分析和跟踪驱动仿真,验证了该算法的有效性。
