In our work, we consider ESP-NOW: a connectionless WiFi communication protocol developed by Espressif and featuring short packet (up to 250 bytes) transmission. It is different from more traditional WiFi protocols, as the upper five layers of the Open Systems Interconnection (OSI) stack are simplified to a single monolithic layer. The data does not need to travel through all the OSI-or Transmission Control Protocol (TCP)-specific layers, which measurably reduces over-head, processing delay all while increasing system responsiveness. The presented work targets the considerable research gap in regards to this protocol and constitutes an attempt to dissect it and provide experimental results, which prove to be promising for highly mobile clusters. Relevant developments find great applicability in ad hoc and vehicular communications, where real-time connectivity and sufficient coverage are pivotal in supporting reliable networking. In this paper, we also investigate the usage of a modified 802.11 standard to enable long-range and low-power interfacing amongst networked vehicular nodes.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"75 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77617500","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 the introduction of two or more factors improved existing authentication procedures and gave rise to new multi-factor authentication schemes, more advanced and focused assaults have revealed they are also sensitive and ineffective to assure only authorized access to systems. This study suggests a revolutionary two-factor authentication mechanism that uses QR codes and honeytokens. In the current implementation, honeywords and Google authenticator work together. In order to speed up the identification process, the honeywords technique is utilized as a second factor on a different computing device. By using a stronger and more effective authentication mechanism than a single password mechanism or a common two-factor authentication scheme, the novel and straightforward approach presented here intends to add additional layers of security and protection into a system, thereby increasing its security.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"13 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77260054","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 valid identification of any gait deviation, as an abnormality in the gait cycle, can help in the real-time monitoring of patients with neuromuscular and musculoskeletal causes, and eventually in the restoration of their normal gait function. The current study combines multiple data preprocessing approaches with supervised machine learning algorithms to provide a framework for recognizing diverse gait activities using data samples from the publicly accessible “HuGaDB” human gait database. The automated analysis method takes into account 3-dimensional (3D) signals derived from two types of inertial sensors: accelerometers and gyroscopes, as well as electromyography (EMG) devices placed on the right and left leg of 18 healthy human participants.

This is mainly triggered by two key reasons. The first one is its importance for the social performance of communities. Public are becoming more sensitive in social issues lately, and accessibility is considered a cornerstone towards this direction. Moreover, accessibility becomes essential towards sustainable development, due to its business importance. Efficiently handling accessibility issues and accommodating the special needs of people with disabilities may provide a robust business environment and substantial exploit market opportunities. To that end, the need for accessibility, especially in urban environments, is vital and ICT can play a key role towards enhancing accessibility. There are several tools and applications already available to serve this goal. This work presents a novel tool, namely the Seek & Go application, which is a holistic aid application for disabled people with features of a GPS navigation system, especially designed for pedestrians with mobility problems and special accessibility requirements. The paper briefly discusses the key technical aspects, while also presents user experience insights and description of the models and document schemas that have been selected for its development.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"37 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84109131","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}

As a result, drone swarms are being applied in various applications nowadays, as they can sense and process information from the surrounding environment to achieve higher level of functionality. For example, drone swarms are employed in disaster control and large area monitoring to prevent catastrophic events such as wild fires. For drone swarms to operate properly, a critical aspect is their remote command and control capabilities. Since swarms can possibly consist of an increased number of drones, it is important that they hold a certain degree of autonomy. In the current work, a Coverage Path Planning (CPP) algorithm is proposed for unknown area exploration. The proposed algorithm discovers the Wireless Sensor Network (WSN) nodes within the area and, then, it collects their data under a data collection scheme being used. For evaluating the proposed algorithm, a simulated environment is developed to assess its effectiveness in terms of fairness in data collection from the WSN nodes. Fairness, in the current case, measures the percentage of data collected from the WSN nodes and is calculated multiple times during the experiments. Two coverage paths are considered here, the parallel lines and the spiral lines. The results showcase that the coverage path affects the fairness index while the parallel lines seem to provide more consistent data collection than the spiral, the latter increasing the fairness index.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"32 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81784562","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}
