Abstract

In view of the problem that it is difficult to accurately describe the dynamic working principle of the system and reproduce the motion control function of the real system when the virtual reality technology of the complex system is applied, the hydraulic six degrees of freedom (six-DOF) parallel mechanism with high order, nonlinear, strong coupling and other characteristics was used as the research object, and a virtual reality technology using user datagram protocol (UDP) was proposed between the professional software MATLAB and the virtual reality development software Unity3D. Firstly, the three dimensions (3D) model of the parallel mechanism was built in the 3D modeling software SolidWorks, and the model was imported into the Unity3D software and the joint constraints were applied on it. Secondly, the inverse kinematics of the parallel mechanism was solved, and the joint simulation model of the MATLAB software and the AMESim software was established. Finally, through UDP, Two-way real-time data interaction was realized between the MATLAB software and the Unity3D software, and the virtual mechanism was drove to action. The results show that the actions of the virtual mechanism are fully conformed to the working principle of the real physical system, and the virtual reality technology based on the UDP data-driven is good accuracy and real-time performance.

Abstract

Abstract Thermal imaging technology has become increasingly popular for various applications, including industrial monitoring, building automation, and medical diagnostics. However, existing thermal imaging systems often come with high costs and limited connectivity options. In this paper, we propose a method to address these challenges by utilizing the ESP8266 microcontroller to create a thermal imaging system that can measure thermal pixel values, transfer the data wirelessly using the ESP8266’s networking capabilities and display the pixel data in real-time on a Thin-film-transistor liquid-crystal (TFT) display. The objective is to establish a seamless and real-time transfer of thermal images within a local network environment. User datagram protocol (UDP) supports transmission via broadcast and multicast, making it highly efficient for delivering data to multiple clients or devices on a network. It allows a single UDP packet to be simultaneously sent to multiple destinations, enhancing its effectiveness. This feature simplifies the implementation of network protocols and applications, reducing their overall complexity. UDP is particularly well-suited for devices with limited resources, such as microcontrollers or embedded systems, where memory and computing power are constrained. Experimental results demonstrate the successful transmission and display of thermal pixel data between the ESP8266 microcontrollers using the UDP protocol. The project utilizes the Arduino framework along with ESP8266WiFi and UDP libraries to enable network connectivity and UDP communication. The sender and receiver devices are connected to the same local network, guaranteeing efficient and low-latency transmission of thermal pixel data. The system achieves real-time communication within a radius of approximately 15–18 m, ensuring immediate visualization of thermal images on connected displays. By minimizing latency, the system enables a seamless and instantaneous viewing experience offering seamless and instantaneous image visualization for the users.

Abstract

This article presents the algorithmic support of the external monitoring and routing system of autonomous mobile robots. In some cases, the practical usage of mobile robots is related to the solution of navigation problems. In particular, the position of ground robots can be secured using unmanned aerial vehicles. In the proposed approach based on the video image obtained from an external video camera located above the working area of mobile robots, the location of both robots and nearby obstacles is recognized. The optimal route to the target point of the selected robot is built, and changes in its working area are monitored. Information about the allowed routes of the robot is transmitted to third-party applications via network communication channels. Primary image processing from the camera includes distortion correction, contouring and binarization, which allows to separate image fragments containing robots and obstacles from background surfaces and objects. Recognition of robots in a video frame is based on the use of a SURF detector. This technology extracts key points in the video frame and compares them with key points of reference images of robots. Trajectory planning is implemented using Dijkstra’s algorithm. The discreteness of the trajectories obtained using the algorithm for finding a path on the graph can be compensated for on board autonomous mobile robots by using spline approximation. Experimental studies have confirmed the efficiency of the proposed approach both in the problem of recognition and localization of mobile robots and in the problem of planning safe trajectories.

Abstract

Motion assistance exoskeletons are designed to support the joint movement of people who perform repetitive tasks that cause damage to their health. To guarantee motion accompaniment, the integration between sensors and actuators should ensure a near-zero delay between the signal acquisition and the actuator response. This study presents the integration of a platform based on Imocap-GIS inertial sensors, with a motion assistance exoskeleton that generates joint movement by means of Maxon motors and Harmonic drive reducers, where a near zero-lag is required for the gait accompaniment to be correct. The Imocap-GIS sensors acquire positional data from the user's lower limbs and send the information through the UDP protocol to the CompactRio system, which constitutes a high-performance controller. These data are processed by the card and subsequently a control signal is sent to the motors that move the exoskeleton joints. Simulations of the proposed controller performance were conducted. The experimental results show that the motion accompaniment exhibits a delay of between 20 and 30 ms, and consequently, it may be stated that the integration between the exoskeleton and the sensors achieves a high efficiency. In this work, the integration between inertial sensors and an exoskeleton prototype has been proposed, where it is evident that the integration met the initial objective. In addition, the integration between the exoskeleton and IMOCAP is among the highest efficiency ranges of similar systems that are currently being developed, and the response lag that was obtained could be improved by means of the incorporation of complementary systems.

Abstract

In view of problems of low automation degree and high time and labor cost of static test method of mine personnel positioning accuracy, a mine personnel positioning accuracy verification system based on Hall sensing was proposed. The system uses public UDP interface to interface with different types of positioning base stations of different manufacturers, uses proprietary UDP interface to transmit related ranging messages of Hall sensing device, and uses production-consumption model to collect, parse and store communication data. The Hall ranging result is used as the reference data, and the node positioning distance information collected by positioning base station is compared in real time, so as to verify accuracy of the positioning system. The test results show that the minimum ranging error rate of the system itself is 0.80%, the maximum error rate is 3.30%, and the average error rate is 1.38%, which is much lower than the 5% error rate allowed by the personnel positioning accuracy verification system. The results of accuracy verification application example show that the system can effectively verify the accuracy of positioning system.

Abstract

U ovom radu proučavamo kako možemo koristiti ASIO biblioteku za mrežno programiranje. U prvom poglavlju ovog rada govorimo općenito o mrežnom programiranju. Uvodimo terminologiju koju ćemo koristiti u radu. Osim toga opisana je slojevita struktura koja je nezaobilazni dio aplikacije koja koristi mrežno programiranje. U preostalim poglavljima proučavamo klase i funkcije koje nam pruža ASIO biblioteka. Proučavanje započinjemo utičnicama i proučavanjem kako one omogućuju razmjenu podataka. Da bismo mogli razmjenjivati podatke prvo moramo povezati procese. Nakon što smo naučili glavne načine za povezivanje utičnica, obrađujemo metode i funkcije za slanje i primanje poruka. Metode i funkcije dijelimo na sinkrone i asinkrone te objašnjavamo prednosti i mane svakog od tih pristupa. Rad je većinom baziran na TCP transportnom protokolu jer ćemo njega koristiti u završnom poglavlju, tj. u izradi projektnog zadatka. Kako se i UDP protokol često koristi navodimo razlike u kodu s obzirom na to koji se protokol koristi. Za kraj prikazujemo kako sve segmente možemo spojiti u jednu cjelinu. Kao projektni zadatak implementiramo HTTP protokol. Za početak kažemo nešto općenito o protokolu, a zatim implementiramo klijenta i poslužitelja koji komuniciraju koristeći HTTP protokol. In this paper we study how we can use the ASIO library for network programming. In the first chapter of this paper, we talk about network programming in general. We introduce the terminology that we will use in the paper. In addition, a layered structure is described, which is an indispensable part of an application that uses network programming. In the remaining chapters, we study the classes and functions provided by the ASIO library. We begin the study with sockets and studying how they enable data exchange. To be able to exchange data, we first need to connect the processes. After learning the main ways to connect sockets, we cover the methods and functions for sending and receiving messages. We divide methods and functions into synchronous and asynchronous and explain the advantages and disadvantages of each of these approaches. The work is mostly based on the TCP transport protocol because we will use it in the final chapter, i.e. in the creation of the project assignment. As the UDP protocol is also often used, we list the differences in the code with regard to which protocol is used. Finally, we show how all segments can be combined into one whole. As a project task, we implement the HTTP protocol. First, we say something general about the protocol, and then we implement a client and server that communicate using the HTTP protocol.

Abstract

Savremene namenske radio-komunikacije zasnivaju se na internet protokolu. Efikasnost namenskih radio-komunikacija zavisi od propusnosti. Na propusnost namenskih radio-komunikacija utiču i transportni protokoli. U radu je analizirana propusnost transportnih protokola TCP (Transport Control Protocol) i UDP (User Datagram Protocol) u VF (visoko frekvencijskim) i VVF (vrlo visoko- frekvencijskim) namenskim radio-komunikacijama sa očekivanim vremenima kašnjenja i verovatnoćom greške po paketu podataka. Ocenjena je mogućnost njihove primene u namenskim radio-komunikacijama. Pri tome je uzet u obzir uticaj sledećih faktora: vreme povratnog puta, veličina paketa podataka, veličina prozora i verovatnoća greške po paketu podataka. Transportni protokol sa većom propusnošću pogodniji je za primenu u namenskim radio-komunikacijama. Veća propusnost transportnih protokola znači da je veća i propusnost namenskih radio-komunikacija.

Abstract

Developments in computer networking have raised concerns of the associated Botnets threat to the Internet security. Botnet is an inter-connected computers or nodes that infected with malicious software and being controlled as a group without any permission of the computer’s owner. This paper explores how network traffic characterising can be used for identification of botnet at local networks. To analyse the characteristic, behaviour or pattern of the botnet in the network traffic, a proper network analysing tools is needed. Several network analysis tools available today are used for the analysis process of the network traffic. In the analysis phase, the botnet detection strategy based on the signature and DNS anomaly approach are selected to identify the behaviour and the characteristic of the botnet. In anomaly approach most of the behavioural and characteristic identification of the botnet is done by comparing between the normal and anomalous traffic. The main focus of the network analysis is studied on UDP protocol network traffic. Based on the analysis of the network traffic, the following anomalies are identified, anomalous DNS packet request, the NetBIOS attack, anomalous DNS MX query, DNS amplification attack and UDP flood attack. This study, identify significant Botnet characteristic in local network traffic for UDP network as additional approach for Botnet detection mechanism.

Abstract

This paper presents the possibilities of broadcasting and dissemination of experimental data, obtained from direct real-time measurements of a physical objects - small turbojet engine MPM-20. The key factor of this data transfer is to minimize latency of the data transfer and computational overhead that may slow down or jam the control computer. This is why the usage of UDP protocol has been proposed. Since the utilization of the existing measuring aperture with both original hardware (HW) and software (SW) acquisition equipment is necessary, the proposed solution is not created using modifications of original HW and SW modules but the addition of newly created ones. Whereas the remote monitoring of the MPM-20 also requires audiovisual (A/V) contact, we also propose a module to transfer A/V as a stream from an array of IP cameras that are capturing the area of the object MPM-20 in the real time.

Model-Free Control (MFC), which is easy to implement both from software and hardware viewpoints, permits the introduction of a high level control synthesis for the Industrial Internet of Things (IIoT) and the Industry 4.0. The choice of the User Diagram Protocol (UDP) as the Internet Protocol permits to neglect the latency. In spite of most severe packet losses, convincing computer simulations and laboratory experiments show that MFC exhibits a good Quality of Service (QoS) and behaves better than a classic PI regulator., Comment: 28th Mediterranean Conference on Control and Automation (MED'2020), 16-19 June, 2020 -- Saint-Rapha\"{e}l, France

26. An improved UDP protocol for video transmission over Internet-to-wireless networks.

Author

Zheng, H. and Boyce, J.

Abstract

Packet video will become a significant portion of emerging and future wireless/Internet traffic. However, network congestion and wireless channel error yields tremendous packet loss and degraded video quality. In this paper, we propose a new complete user datagram protocol (CUDP), which utilizes channel error information obtained from the physical and link layers to assist error recovery at the packet level. We propose several maximal distance separable (MDS) code-based packet level error control coding schemes and derive analytical formulas to estimate the equivalent video frame loss for different versions of user datagram protocol (UDP). We validate the proposed packet coding and CUDP protocol using MPEG-coded video under various Internet packet loss and wireless channel profiles. Theoretic and simulation results show that the video quality can be substantially improved by utilizing the frame error information at UDP and application layer [ABSTRACT FROM PUBLISHER]

Abstract

This work addresses the design and implementation of a wireless connection for the remote control of the joints of a redundant 3-DoF 1 1 DoF: Degrees of Freedom. manipulator robot. To this end, low-cost devices able to establish master/slave connections are used as closed control loops to calculate both control in the master device and actuation in the slave devices. To test the performance of this wireless connection, classic robot controllers are designed, simulated, analyzed, implemented, and compared through a decentralized structure. The platform Raspberry Pi and UDP 2 2 UDP: User Datagram Protocol. protocol are used to obtain and process data sent to the robot control system, and to send control signals to the robot actuators. Additionally, the feasibility of synthetizing control systems for highly non-linear robots and, in turn, of commanding this system through a remote wireless communication system is demonstrated.

Abstract

Berkeley UNIX® 4.2BSD is an operating system that provides alternative ways for processes to communicate with each other. User processes may choose intermachine communications media, network protocols, addressing families, and styles of communication. In particular, user processes may use datagram or stream communication. In this paper we present a study of the performance achieved by user processes when using the IPC mechanisms as implemented in Berkeley UNIX 4.2BSD in Ethernet based environments. This study not only assesses the impact that different processors, network hardware interfaces, and Ethernets have on the communication across machines, but also the effect of the loading of the hosts and communication media that participate in the interprocess communication mechanism. Our measurement highlight the ultimate bounds on performance that may be achieved by user process applications communicating across machines, and serve as a guide in designing performance critical applications. Moreover, we present a detailed timing analysis of the dynamic behavior of the TCP/IP and the UDP/IP net- work communication protocols' implementation in Berkeley UNIX 4.2BSD. This analysis sheds light on architectural constraints of UNIX, on the tradeoffs encountered when software and hardware perform the same actions on data (e.g., checksums) and when several buffering schemes coexist at different levels in a system.

Abstract

The communication system is a very important part of the robot soccer. It is because the robots must be able to move together, alternate and individual. The communication system that would be discussed is about the process of sending data from one robot to another robot using coach computer. It started with the reception of data from coach computer to both robots that had been installed Wi-Fi Communication module that had been connected to the router. Then, the data is processed using Arduino Mega2560. After that, the robot would detect the existence of the ball. The protocol used for the communication system is a UDP protocol (User Datagram Protocol) because UDP has several characteristics that support the occurrence of communication robots such as connection-less and unreliable. Both of characteristics have a faster connection, they do not require handshaking and UDP protocol provides a mechanism for sending a message to a specific process. The result shows that the communication system between coach computer and both robots is successful. This is indicated by the start button and stop button is 100% with repeating data transfer system on UDP protocol.

Abstract

RESUMEN: Durante los últimos años se ha producido un crecimiento exponencial en cuanto a lo que se refiere a las necesidades y exigencias del usuario a la hora de utilizar redes inalámbricas. Esto ha supuesto que vayan surgiendo multitud de técnicas y mecanismos que tratan de mejorar el rendimiento de dichas redes, tratando de acercarse a las prestaciones ofrecidas por las redes cableadas. A lo largo de este documento se presenta un estudio de la influencia que tienen las técnicas de codificación sobre redes inalámbricas, con el fin de conseguir mejoras en el rendimiento, en términos de throughput. En particular se analizará el mecanismo MORE sobre tráfico UDP, con el fin de cuantificar y valorar los beneficios obtenidos mediante la codificación aleatoria de la información por parte del nodo transmisor. Se realizará una comparación entre dichos resultados y los conseguidos con el protocolo TCP. Para analizar los beneficios y posibles inconvenientes de la aplicación de esta técnica, en este proyecto se ha hecho uso de la herramienta NS-3. Tras la implementación de la nueva entidad (MORE), y tras realizar un gran número de simulaciones, se ha observado un incremento del rendimiento respecto a una solución más tradicional, basada en el protocolo TCP. Es importante destacar que, a pesar de que existen diferentes estudios similares, han sido pocos los que se han centrado en redes inalámbricas, ya que la mayoría son trabajos llevados a cabo sobre redes cableadas. ABSTRACT: In the latest years, the needs and requests from the users of wireless networks have experienced an exponential growth. This has brought about the appearance of several new techniques , aimed at improving the performance of such networks, trying to get closer to the performances o ered by wired networks. This project studies the in uence that coding techniques might have over wireless networks, in order to improve their performance. In particular, we carry out an analysis of the MORE mechanism over the UDP protocol, assesing the bene ts of using random coding at transmitter. A comparison between such results and the ones obtained using the legacy TCP protocol will be also presented in this document. In order to analyze the bene ts and potential drawbacks of this technique, we have used the NS-3 tool. After developing the new entity (MORE) and performing a large number of simulations, we have seen observed a performance improvement in comparison with a more traditional solution based on the TCP protocol. It is worth mentioning that, although there ara several similar studies, those have focused on wired networks. Ingeniería de Telecomunicación

Abstract

The paper deals with the problem of transmission of multimedia content in public network for data transmission based on IP protocol. It covers the properties of the IP protocol, the way to build up a network based on this protocol and properties of transmission appearing in the IP networks. Through the use of the TCP protocol it is necessary to ensure the proper data transmission between two end points (IP does not guarantee correct transmission), ensured are the integrity of the data received, correct sequence, control of transmission and prevention of congestion. The TCP will always send and receive data with maximal speed. The TCP will adjust the speed of sending off and receiving to properties of the weakest connection between source and target point in the IP network. Traffic with such dynamic property of adjustment of the state in the network, is called flexible traffic.

Abstract

In this article, an Internet-based remote control system is designed and implemented. The communication is based on the Master-Slave structure. The Master PC communicates with the Slave from about 40km away by UDP protocol. In order to guarantee the Master and Slave clocks to be synchronized, the NTP (Network Time Protocol) is used in both sides. The packets are sent together with time-stamps. The controller design (master) relies on a remote observer that achieves a state prediction of the application (slave), despite the variable communication delays. The Slave comprises a PC and a robot Miabot of Merlin company. The protocol Bluetooth is used between the local PC and the robot. Internet-based remote systems are subject to variable time delays (including communication and data-sampling delays) and data packets losses (due to the unstable Internet network). We have continuously tested the RTT (round-trip-time) between the two PCs in the daytime and nighttime by the protocol ICMP (Internet Control Message). From these tests, an evaluation of the maximal time delay is obtained. Our structure allows one to guarantee an exponential stabilization performance, which is proven via a Lyapunov-Krassovski functional technique and involves the estimated delay upperbound. This means that the guaranteed decay rate is computed (via some LMI optimization) in relation to some maximal value of the communication delays. Of course, for greater delay values, the performance cannot be guaranteed anymore and an alternative solution has to be considered. In our system, we give a command for the robot to stop until the communication comes back to a sufficient quality., QC 20141020

Abstract

Berkeley UNIX 4.2BSD is an operating system which provides alternative ways for processes to communicate with each other. User processes may choose, for example, intermachine communications media, protocols, addressing families, and styles of communication. In particular, user processes may use datagram or stream communication. In this paper we present a study of the impact that IPC mechanisms, as currently implemented in Berkeley UNIX 4.2BSD in Ethernet based environments, have, from the user process viewpoint, on the performance of distributed applications. This study not only assesses the impact that different processors, network hardware interfaces, and Ethernets have on the communication across machines between user processes, but also the effect of the loading of the various components which participate in the interprocess communication mechanism. Thus, host and ether loads are also taken into account in our study. Our measurements highlight the current ultimate bounds on performance which may be achieved by user process applications communicating across machines, and serve as a guide in designing performance critical applications. For this study, hosts and ethers have been loaded with a user defined mix of tasks, i.e., an artificial workload. Moreover, we present a detailed timing analysis of the dynamic behavior of the TCP/IP and the UDP/IP network communication protocols' current implementation in Berkeley UNIX 4.2BSD. This study sheds light on the tradeoffs encountered when software and hardware perform the same actions on data, e.g., checksums, and when several buffering schemes coexist at different levels in the system., Sponsored in part by the Defense Advanced Research Projects Agency.
