Because of personnel deployment flow, protection equipment and electric device replacement, and enterprise scale expansion, setting management is more difficult. It is easy to be out of control and become the main reason for the anti-grade trip. To solve the anti-grade trip problem of setting mismanagement, this paper designed one setting management system, which is composed of slave controller and upper server. After analysis, the communication process based on the TCP/IP protocols, the communication scheme is chosen between slave controller and upper server. Software within upper server is designed based on database technology. Slave controller gets the setting from relay protection device, by using IEC 60870-5-103 protocols based on serial communication, and sends to the software within the upper server, which can monitor, display and record. Setting management problem was solved, which is caused by the personnel deployment flow, protection equipment replacement, and enterprise scale expansion. This method can be widely used.

This solution can allow the master board to dynamically discover configure boot and release the slave boards according to service demands and provides all images to the slave boards. This architecture is reliable scalable and low power consumption.

This paper first designed the overall scheme of a wireless-based intelligent environment monitoring system; this system is comprised of the following four parts: server part, client part, slave computer part, and master computer part. The master computer is equipped with a wireless transmission module and an LCD module. Slave computers are equipped with temperature-humidity sensing modules and wireless transmission modules. The server side has two major interfaces: data display and server establishment. An Android phone as the client can realize the communication between the mobile APP and server through network communication to obtain environmental data in real time. The hardware part of the system consists of wireless transmission module, temperature and humidity module, smoke module, lighting module, flame module, and LCD module. The software implementation part mainly includes the design and implementation of serial communication, the design and implementation of wireless communication, the design and implementation of collection of data acquisition in each sensor module, and the design and implementation of network communication as well as the design and implementation of display unit. With the cooperation of these four parts, we can automatically sense and control the state of the environment to realize human-computer interaction.

The network storage systems are generally composed of clients, storage servers and metadata servers. In this paper, we proposed a novel storage virtualization (NSV) scheme which is capable of alleviating the heavy load of metadata server, guaranteeing the storage quality of service and dynamically adapting storage resources. The metadata server automatically constructs a dedicated storage cluster according to various requirements of storage quality of service. The storage cluster may consist of one to many storage servers which includes one master storage server and zero to many slave storage servers. In other words, a network storage system consists of at least one storage cluster. The requests of each client are forwarded to corresponding master storage server within a specific storage cluster. In addition, the master storage server determines the best storage server which handles the requests based on the conditions of storage servers. Next, the requests will be redirected to the selected storage server. Finally, the responses are directly transmitted to the client.

Perancangan wireless sensor network dengan topologi mesh berhasil direalisasikan, di mana ketika salah satu modul slave yang tidak berfungsi, semua data dari modul slave yang berfungsi tetap dapat diterima oleh modul master.

In recent years, cluster technology is used more wildly. In this paper, we present a new method to implement a streaming media cluster server. The server is constructed on a high performance cluster which consists of one control node, one storage node and 8 computing nodes. We wrote a parallel program with MPI which run on the cluster. The organization of MPI program is a master-slave scheme. The master interacted with users and scheduled task within slaves. Slaves called streaming media server which sent data directly to user. This can improve the system performance significantly. We can also guarantee the transparence of the service by single access point named IP Tunneling. The system was implemented under Linux platform and tested through simulation testing method. From the testing results, it can be confirmed that the whole system is well designed which achieves high performance, good robustness and high scalability.

Puskesmas sebagai unit kesehatan tingkat pertama memiliki tugas pokok yaitu pengobatan, perawatan kesehatan, kesehatan lingkungan, membina kesehatan ibu dan anak, pencegahan penyakit menular, pencatatan dan pelaporan. Dari keseluruhan tugas tampaknya tidak seluruhnya digarap oleh puskesmas terutama pencatatan dan pelaporan untuk pencegahan penyakit menular serta pola penyebarannya. untuk mengawasi dan mengendalikan perencananan program kesehatan termasuk penekanan penyebaran penyakit menular, puskesmas belum memiliki alat bantu yang terintegrasi satu atap secara real time dengan dinas kesehatan, untuk itu dibutuhkan sistem informasi geografis (SIG) untuk memvisualisasikan data penyakit menular, hal ini juga perlu ditunjang perangkat yang optimal dengan biaya yang murah dengan menggunakan raspberry pi sebagai kendali otomasi server data dalam replikasi.

Mobile Agent (MA) technology has been recently proposed in Wireless Sensors Networks (WSNs) literature to answer the scalability problem of client/server model in data fusion applications. Herein we present CBID, a novel algorithm that calculates near-optimal routes for MAs that incrementally fuse the data as they visit the Sensor Nodes (SNs) while also enabling fast updates on the designed itineraries upon changes of network topology. CBID dispatches in parallel a number of MAs that sequentially visit sensor nodes arranged in tree structures and upon visiting an SN with two or more child SNs, the MAs (master MAs) clone of themselves with each clone (slave MA) visiting a tree branch. When all slave MAs return to that SN, they deliver their collected data to the master MA and are then disposed of. This results in a significant reduction of the overall energy expenditure and response time. Simulation results prove the high effectiveness of CBID in data fusion tasks compared to other alternative algorithms.

This study aimed to propose a pure web-based solution to serve users to access large-scale 3D medical volume anywhere with good user experience and complete details. A novel solution of the Master-Slave interaction mode was proposed, which absorbed advantages of remote volume rendering and surface rendering. On server side, we designed a message-responding mechanism to listen to interactive requests from clients (Slave model) and to guide Master volume rendering. On client side, we used HTML5 to normalize user-interactive behaviors on Slave model and enhance the accuracy of behavior request and user-friendly experience. The results showed that more than four independent tasks (each with a data size of 249.4 MB) could be simultaneously carried out with a 100-KBps client bandwidth (extreme test); the first loading time was <12 s, and the response time of each behavior request for final high quality image remained at approximately 1 s, while the peak value of bandwidth was <50-KBps. Meanwhile, the FPS value for each client was ≥40. This solution could serve the users by rapidly accessing the application via one URL hyperlink without special software and hardware requirement in a diversified network environment and could be easily integrated into other telemedical systems seamlessly.

CERN is using an increasing number of DNS based load balanced aliases (currently over 700). This article explains the Go based concurrent implementation of the Load Balancing Service, both the client (lbclient) and the server (lbd). The article describes how it is being progressively deployed using Puppet and how concurrency greatly improves scalability, ultimately allowing a single master-slave couple of Openstack virtual machines to server all the aliases. It explains the new implementation of the lbclient, which, among other things, allows to incorporate Collectd metrics to determine the status of the node and takes advantage of the Go language concurrency features to reduce the real time needed for checking the status of the node. The article explains that the LBD server acts as an arbiter getting feedback on load and health from the backend nodes using snmp (Simple Network Management Protocol) to decide which IP addresses the LB alias will present. While this architecture has been used since long at CERN for DNS based aliases, the LBD code is generic enough to drive other load balancers. A proof of concept using HAProxy to provide adaptive responses to load and health monitoring has been implemented.

DoS (denial of service) assault is the most prevalent assault these days. It imposes a major risk to cybersecurity. At the point when this assault is propelled by numerous conveyed machines on a solitary server machine, it is called as a DDoS (distributed denial of service) assault. Additionally, DoS bypass on DHCP (dynamic host configuration protocol) server assault is a rising and famous assault in a system. The authors have proposed a stochastic intrusion detection game-based arrangement utilizing controlled Markov chain that figures the transition probabilities starting with one state then onto the next in a state transition diagram. At first, the authors have conjectured these assaults, and after that, they proposed a methodology that uses the idea of master and slave IPS (intrusion prevention system). This approach works well when mapped to these estimated assaults and accordingly helps in the recognition and counteractive action of these assaults in a cloud domain.

Actually, investors from several industrial sectors are looking for process improvements that aim at profitability and greater competitiveness in the market, however, characteristics such as cost, information and production agility are determining points for this. Open source input and output control platforms that integrate microcontrollers have been gaining ground in several sectors, where programmers have the ability to control processes and manage data. In this way, this article presents the development of a real time monitoring system of physical quantities based on Arduino and Raspberry. The complete system will consist of two modules, "Slave" and "Master", in which the data transfer of the measurements of temperature, humidity, luminosity, pressure and others will be carried out. The slave, formed by inexpensive sensors connected to an Arduino MEGA 2560, will be allocated at a remote location to acquire the desired physical quantities. The Master, will receive the information through an ethernet shield, connected in both modules, and will manage the database. The information stored on the web server can be accessed via internet browser, either in desktops or mobile systems through a friendly platform in real time.

Helmet theft is a problem that is of concern to the public. Information Technology provides may resolve any problems, like Internet of Things-based system that can detect helmet theft and track the location of the helmet if it's stolen. This system is designed using a microcontroller device, namely Arduino which is attached to the helmet and motorbike with the help of the SIM800L v2, GPS Neo-6m, buzzer, and Bluetooth HC-05 which is connected to the master slave as an indicator of the safety of the helmet. The hardware on the helmet is connected to Firebase Realtime Database server so it can be connected with the user's Android application to monitor the state and location of the helmet. Android application displays maps to determine the position of the helmet, and can display notifications when the helmet is being stolen. The conclusion is this system can detect helmet theft with a maximum distance from the master and slave bluetooth connections of 10 meters, and the average data transmission from hardware to Firebase is 1,1 seconds, and can monitor status of the helmet and track the position of the helmet through the Android application with Android Jelly Bean (v4.3) operating system.

Penyimpanan susu segar membutuhkan pengaturan dan pemantauan suhu yang optimal agar kualitas susu segar dapat dipertahankan. Kondisi saat ini cold storage hanya bisa menampilkan temperature susu saat ini, tetapi data histori temperature dan keasaman susu tidak terekam dengan baik.

Penelitian ini mengusulkan Perangkat IoT Master dan Slave yang dapat digunakan untuk menyelesaikan permasalahan penyimpanan, pemantauan dan pengendalian persedian susu segar. IoT Node terdiri dari sensor suhu ruang, suhu susu, Ph meter, dan ultrasonic. Data dari sensor akan diproseses oleh IoT Node untuk kemudian dikirim ke IoT Master Controller. IoT Master Controller akan mengirimkan data ke server cloud. Berdasarkan data tersebut maka kondisi susu dalam cold storage dapat dipantau kualitas dan ketersediaannya.

In this day people are asking for a reliable network when technology at its limit. Software-Defined Network (SDN) is an answer to that problem of network development where all the control over the network becomes centralized. However, all services controlled by a centralized controller have a big disadvantage if the controller dies. The High Availability (HA) is the solution. HA controller is divided into master and slave, when master controller is down then slave controller will respond to replace the function of master controller. In this research the system will be made by using two methods namely OpenDayLight SDN Controller Platform (OSCP) clustering and Heartbeat-DRBD (Distributed Replicated Block Device). OSCP clustering is a feature on OpenDayLight controller that is ready to be used and only need to be configured, with OSCP the main and backup controller clustering will be on connected cluster. Heartbeat-DRBD is an application commonly used to create High Availability systems on a server, but in this study will be used for the controller, Heartbeat will monitoring the main controller and if indicated to be down will move the resources to the backup controller with the DRBD application. From the simulation result shows that OSCP Clustering Failover and Failback average Time is 17 seconds while Heartbeat-DRBD is 23-45 seconds depends on how many switch and host are.While QoS parameters on both method have simillar value.it can be concluded that the High Availability system with OSCP Clustering method is more stable and good rather than Heartbeat-DRBD method to apply in a network.

Manufacturing industries nowadays need to reconfigure their production lines promptly as to acclimate to rapid changing markets. Meanwhile, exercising system reconfigurations also needs to manage innumerous types of manufacturing apparatus involved. Nevertheless, traditional incompatible manufacturing systems delivered by exclusive vendors usually increase manufacture costs and prolong development time. This paper presents a novel RMS framework, which is intended to implement a Redis master/slave server mechanism to integrate various CNC manufacturing apparatus, hardware control means, and data exchange protocols through developed configurating codes. In the RMS framework each manufacturing apparatus or accessory stands for an object, and information of recognized CNC control panel image features, associated apparatus tuned parameters, communication formats, operation procedures, and control APIs, are stored into the Redis master cloud server database. Through implementation of machine vision techniques to acquire CNC controller panel images, the system effectively identifies instantaneous CNC machining states and response messages once the embedded image features are recognized. Upon demanding system reconfigurations for the manufacturing resources, the system issues commands from Redis local client servers to retrieve the stored information in the Redis master cloud servers, in which the resources for registered CNC machines, robots, and built-in accessories are maintained securely. The system then exploits the collected information locally to reconfigure involved manufacturing resources and starts manufacturing immediately, and thus is capable to promptly response to fast revised orders in a comitative market. In a prototyped RMS architecture, the proposed approach takes advantage of recognized feedback visual information, which is obtained using an invariant image feature extraction algorithm, and effectively commands an industrial robot to accomplish demanded actions on a CNC control panel, as a regular operator does daily in front of the CNC machine for manufacturing.

Cuaca merupakan salah satu faktor yang memengaruhi aktivitas manusia. Oleh karenanya informasi mengenai kondisi cuaca yang akurat menjadi hal penting dan umumnya itu dapat diperoleh dari situs-situs di internet. Namun demikian, informasi tersebut lazimnya berkenaan dengan suatu wilayah dengan cakupan yang luas dan tidak memaparkan iklim mikro di lingkup lokal. Tujuan dari penelitian ini adalah melakukan rancang bangun suatu sistem penampil data cuaca berbasis Arduino Uno R3 untuk menayangkan data iklim di cakupan lokal dengan tiga mode tampilan data. Sistem ini menggunakan sensor BME280 untuk mengukur suhu (°C), kelembaban relatif (%), tekanan udara (hPa) dan ketinggian (m) dan sensor BH1750FVI untuk mengukur intensitas cahaya (lx). Waktu dan tanggal terjadinya pengukuran ditandai oleh RTC DS3231. Semua piranti tersebut menggunakan antarmuka I2C bertegangan kerja 3,3 V, yang bertindak sebagai slave dengan alamat perangkat yang berbeda-beda. Dari hasil pengukuran didapatkan bahwa nilai rerata suhu dan kelembaban, masing-masing adalah 28,72°C dan 65% dengan error 7,42% dan 10,95% yang mengindikasikan adanya bias antara hasil ukur di lingkup mikro dengan nilai pembanding dari situs cuaca yang mengacu ke wilayah yang lebih luas. Tekanan udara dan ketinggian menunjukkan nilai konstan dengan rerata masing-masing, 1011,2 hPa dan 240,35 m beserta error yang lebih kecil yaitu 0,2% dan 3,86%. Intensitas cahaya berada pada rentang 58,05 – 100,63 lx dengan nilai rerata 83,85 lx. Data cuaca sudah dapat ditampilkan dengan baik melalui web server, komputer dan LCD alfanumerik. Informasi mengenai waktu dan tanggal pengukuran sudah dapat dimunculkan pada tiap mode tampilan yang mengindikasikan bahwa cip RTC telah bekerja sesuai perencanaan.

Reducing residential and industrial electricity consumption has been a goal of governments around the world. Lighting sources account for a large portion of the whole energy/power consumption. Unfortunately, most of the existing installed lighting systems are ancient and have poor energy efficiency. Today, many manufacturers have introduced light-controlling systems into the current market. However, existing light controlling systems may not be successfully applied to buildings, streets, and industrial buildings due to high costs and difficult installation and maintenance. To combat this issue, this article presents an easy-to-install, low-cost, Master-Slave intelligent LED light-controlling system based on Internet of Things (IoT) techniques. The benefit of using the proposed system is that the brightness of the LED lights in the same zone can be changed simultaneously to save in energy consumption. Furthermore, the parameters of the LED lights can be directly set. Moreover, the related data are collected and uploaded to a cloud platform. In this article, we use 15 W T8 LED tubes (non-induction lamps) as a case study. When the proposed system is installed in a zone with few people, the energy-saving rate is as high as 90%. Furthermore, when 12 people pass by a zone within one hour, its energy-saving rate can reach 81%. Therefore, the advantages of using the proposed system include: (1) the original lamp holder can be retained; (2) no wiring is required; and (3) no server is set up. Moreover, the goal of energy saving can also be achieved. As a result, the proposed system changes the full-dark mode of the available sensor lamp to the low power low-light mode for standby. Further, it makes the sensor lamps in the same zone brighten or low-light way simultaneously, which can quickly complete large-scale energy-saving and convenient control functions of intelligent LED lighting controlling system.

Molecular docking aims to predict possible drug candidates for many diseases, and it is computationally intensive. Particularly, in simulating the ligand-receptor binding process, the binding pocket of the receptor is divided into subcubes, and when the ligand is docked into all cubes, there are many molecular docking tasks, which are extremely time-consuming. In this study, we propose a heterogeneous parallel scheme of molecular docking for the binding process of ligand to receptor to accelerate simulating. The parallel scheme includes two layers of parallelism, a coarse-grained layer of parallelism implemented in the message-passing interface (MPI) and a fine-grained layer of parallelism focused on the graphics processing unit (GPU). At the coarse-grain layer of parallelism, a docking task inside one lattice is assigned to one unique MPI process, and a grouped master-slave mode is used to allocate and schedule the tasks. Meanwhile, at the fine-gained layer of parallelism, GPU accelerators undertake the computationally intensive computing of scoring functions and related conformation spatial transformations in a single docking task. The results of the experiments for the ligand-receptor binding process show that on a multicore server with GPUs the parallel program has achieved a speedup ratio as high as 45 times in flexible docking and as high as 54.5 times in semiflexible docking, and on a distributed memory system, the docking time for flexible docking and that for semiflexible docking gradually decrease as the number of nodes used in the parallel program gradually increases. The scalability of the parallel program is also verified in multiple nodes on a distributed memory system and is approximately linear.

The main challenge for the Internet of Things (IoT) is to ensure interoperability between heterogeneous IoT entities. To support the interaction, intercommunication, and interoperability between these devices several solutions are proposed in the literature. The SDN (Software-defined Network) is one of these solutions to resolve the problem of the heterogeneous network used in IoT. To guarantee network interoperability, the SDN uses a centralized controller, which handles the entire network. The role of end devices in IoT is only forwarding data. The MQTT (Message Queuing Telemetry Transport) protocol is another solution for granting interoperability in IoT. Which is a publish/subscribe based messaging protocol that avoids direct connection between devices by relaying data through a central server called the broker. Combination of these two solutions to manage IoT devices makes it easy to add new devices without touching or changing the existing infrastructure. The new devices only need to communicate with the broker. Moreover, the Controller SDN is responsible for handling networks. Consequently, smart devices added don’t need to be compatible with the others. In this paper, we present the design and the implementation of a new IoT architecture, which is a combination of SDN technology and MQTT protocol. That enables heterogeneous IoT devices to be interoperable and interact without any problems. Our system utilizes the lightweight protocol MQTT with a new mechanism using several slave brokers and one master. The slaves manage the group of the end devices in the wireless IoT network, and the master broker installed in the SDN controller supervises the integral network. The SDN controller uses a multicast system to send MQTTdata across the external wireless network. As a result, that reduces transmission delay between wireless IoT network compared with the using of a standard MQTT.

Le premier XIXe si?cle met la Serbie en contact plus intense avec la France, berceau des valeurs d?mocratiques et du patrimoine culturel europ?en aux yeux des Serbes subissant l?occupation turque depuis des si?cles. C?est ? partir de cette p?riode que commencent ? se d?velopper les liens culturels, politiques et ?ducatifs plus ?troits entre deux pays, particuli?rement renforc?s pendant la Grande Guerre, o? la France aide les jeunes serbes en leur ouvrant la porte de ses ?coles et universit?s. La Convention sign?e en 1920 en vue de la mise en place de la coop?ration intellectuelle et ?ducative (surtout universitaire) des deux pays pr?voyait ?galement la position privil?gi?e de la langue fran?aise au sein du syst?me ?ducatif serbe : en effet, dans les ann?es 30 du XXe si?cle, celleci sera la mati?re la plus enseign?e apr?s la langue serbe et les math?matiques, et le Minist?re des affaires ?trang?res fran?aises enverra r?guli?rement des livres fran?ais, ainsi que des dipl?mes et m?dailles pour les meilleurs ?l?ves. En raison de la croissance de l?influence politique italienne et surtout allemande dans les Balkans, un Congr?s des clubs fran?ais de Yougoslavie, tenu en 1935, marque le d?but des d?marches coordonn?es visant ? renforcer la pr?sence fran?aise dans tous les domaines de la vie sociale yougoslave. Les responsables du D?partement d??ducation aupr?s de l?Ambassade yougoslave ? Paris (Aleksandar Arnautovic puis Milan Markovic) informaient r?guli?rement Belgrade des activit?s dans la capitale fran?aise et ailleurs. Les boursiers du Gouvernement fran?ais (qui accordait la moiti? de la somme totale du budget aux ?tudiants yougoslaves, dont le nombre variait entre 60 et 100 par an dans la p?riode 1936-1940), du retour dans leur pays, r?pandront l?esprit de la culture fran?aise, ainsi que les connaissances acquises dans tous les domaines. Parmi les personnalit?s importantes qui excelleront dans leur m?tier se trouvent : Dr Vukan Cupic, professeur ? l?Universit? de Belgrade et directeur de l?Institut belgradois pour la m?re et l?enfant (boursier du fonds d?Alexandre de Yougoslavie de la mairie de Marseille 1938-1940), le chimiste Pavle Savic qui collaborait avec Ir?ne Curie, Dr Borisav Arsic qui a soutenu la th?se La Vie ?conomique de la Serbie du Sud au XIX si?cle (Paris, France-Balkans, 1936), Dr Branislav Vojnovic, directeur du Th??tre national, Dr Milos Savkovic qui ?tudiait l?influence de la litt?rature fran?aise sur le roman serbe etc. Les jeunes yougoslaves choisissent surtout la litt?rature, les arts et les sciences humaines. D?autre c?t?, le gouvernement yougoslave finan?ait chaque ann?e cinq ?tudiants fran?ais faisant la recherche au sein des universit?s yougoslaves. De nombreuses conf?rences sont dispens?es par les professeurs yougoslaves et fran?ais ; les ?coles franco-serbes, l?Institut fran?ais, les clubs et les associations de l?amiti? donnent les cours de fran?ais ; l?Association des ?tudiants en langue et litt?rature fran?aises organise les soir?es fran?aises et va r?guli?rement en excursions en France ; le Minist?re d??ducation finance les formations estivales des professeurs de fran?ais. Du c?t? fran?ais, l?Institut slave, la Chaire de serbo-croate ? l??cole de langues vivantes orientales avec des professeurs ?minents tels Andr? Vaillant et Andr? Mazon, le Lectorat serbe ? Paris, Strasbourg, Lyon etc. contribuaient aux ?tudes yougoslaves. La langue serbo-croate a ?t? inscrite sur la liste des langues vivantes que les ?l?ves pouvaient passer au baccalaur?at en 1936. Pourtant, cet ?panouissement sera de nouveau menac? par une p?n?tration politique et ?conomique des forces de l?Axe de plus en plus forte ? la veille de la Deuxi?me guerre mondiale : c?est ainsi que l?allemand devient la langue ?trang?re obligatoire au detriment du fran?ais en 1940, les entreprises fran?aises ferment leurs portes, tandis que de nombreuses activit?s culturelles et d?marches ?ducatives cherchent ? pr?server l??tat privil?gi? dont la France jouissait en Serbie depuis la Grande Guerre.

Abstract— A fault tolerant system is a system that has the ability to be able to continue its jobs properly although there is a fault in hardware or software of the system. A system that has a fault tolerant capability is usually critical or important system. For example is at Point Of Sale application. Point Of Sale Application has evolved from offline-based toward online-based. With an online-based, the existence of a central database server must be guaranteed free from failure.To get a central database server that is free from failure is impossible. Something that can be cultivated is to create a system that can tolerate a failure in the central database server. This is done with the help of a second central database server (slave), which is useful as a replication of the central database server (master). To ensure data from these two central database servers are the same, then used the concept of reading and writing "read one/write all". And to manage all the processes needed in implementing a fault tolerant application, we need the help from a coordinator.The result obtained in this research is a design of fault tolerant architecture that can be applied to various types of information system applications include Point Of Sale application. By using this fault tolerant architecture that has been built, Point Of Sale application can still run the transaction process even if there is a failure in accessing data in one central database server (master/slave). Keywords— fault tolerance, database system, point of sale application

PurposeThis research proposes an innovative fault-tolerant media content list management technology applied to the smart robot domain.Design/methodology/approachA fault tolerant Content List Management Unit (CLMU) for real-time streaming systems focusing on smart robot claw machines is proposed to synchronize and manage the hyperlink stored on media servers. The fault-tolerant mechanism is realized by the self-healing method. A media server allows exchanging the hyperlink within the network through the CLMU mechanism.FindingsInternet users can access the current multimedia information, and the multimedia information list can be rearranged appropriately. Furthermore, the service of the proposed multimedia system should be uninterrupted even when the master media server fails. Therefore, one of the slave media servers enables the Content List Service (CLS) of the proposed CLMU and replaces the defunct master media server.Originality/valueThe recovery time is less than 1.5 seconds. The multimedia transmission is not interrupted while any one of the media servers keeps functioning. The proposed method can serve to stabilize the system of media servers in a smart robot domain.

Purpose This paper aims to discuss the Silver and Golden ticket exploits that usually exists in the existing systems. To overcome these challenges, the data is first encrypted and then the ticket is granted to the validated user. The users are validated using the user privileges. The security levels of the proposed model are compared with the existing models and provide a better performance using the Key Distribution Centre (KDC). The number of authentication and authorization levels present in the existing and proposed model is also evaluated. Design/methodology/approach The methodology designed in this paper is discussed in this section. The existing models are designed in such a way that the client ID first asked to send an authorization request to the Authentication Server. The server looks up the user in its database and then sends back a ticket generated by it to the client to obtain services for the Service center. Numerous models have some additional features to these systems where the theme of KDC was introduced. The Key Distribution Centre (KDC), which is a set of nodes in a network where the data could be distributed and stored, such that any kind of attack on a single KDC will not impact other KDC and the data stored in it. The nodes other than the KDC in the network are termed as the slave nodes. The slave nodes communicate with each other within the network depending on the topology of the entire network. In this paper, the authors have used the Kerberos protocol for adding more security functions in the entire network. The system developed consists of a client, server and a set of nodes connected to each other in a ring fashion. Findings The proposed model provides security to the information being used by making use of the Kerberos protocol. Additional features and algorithms such as the use of the ticket-granting approach have been added at the protocol to make it more secure than the existing models. The ticket generation is done at the server-side that makes the user have proper authentication to make use of the services available from the server-side. The model is designed in such a way that it could remain operational even during the time of denial of service. As future work, use of machine learning and deep learning could be used to predict the attack on the network well before it is being misused. Originality/value The paper discusses the Silver and Golden ticket exploits that usually exists in the existing systems. To overcome these challenges, the data is first encrypted and then the ticket is granted to the validated user. The users are validated using the user privileges. The security levels of the proposed model are compared with the existing models and provide a better performance using the Key Distribution Centre (KDC). The number of authentication and authorization levels present in the existing and proposed model is also evaluated.

Purpose: The Modbus is the trusted name in the industrial automation communication domain. It is a pretty simple protocol to implement and so very popular to the industrial communication personnel. Nowadays, Some industrial robots are also capable of communicating through Modbus. So our robot researchers frequently face the challenge of communicating with Modbus-enabled devices or robots. They need to know the protocol in detail before integrating it into their project. Its learning curves are a bit higher because of the lack of document which is practical oriented. The protocol selection, packet structure, CRC, or LRC calculation need to maintain precisely as standards; otherwise, the Modbus exception may happen. We experience those scenarios. Through our practical experience, we learned what is required for a new researcher who wants to implement Modbus in their project. In this paper, we demonstrate the Modbus packet structure and implement it with several practical examples. Finally, to test the written code, we provide simple tools which are easy to use and customizable. The researcher can easily integrate into their research project. The complete project source code is available in Github. Design/Methodology/Approach: The Modbus is the standard protocol to communicate between or among the devices. We need a better understanding of it and interface software to test around all aspects. Here we described some practical examples. The GUI is created using C# language inside the Microsoft Visual Studio. The application has several capabilities. In the TCP/IP mode, It can be a server or client. In RTU mode, it can play as a Master or slave device. We can also run two instances in a single system. To communicate between two running apps in RTU mode, we need virtual loopback software, two physical comm port, or two USB to Serial modules. For Modbus TCP mode, we can test within the system using the localhost address (127.0.0.1) or need an IP address for a different. Findings/results: The robot researcher can find helpful information about communicating the robot through the Modbus protocol. The practical example can help them to create packet purser. The functional CRC algorithm code can be used for better understanding and implementation into their project. Originality/Value: This work has some different features than other available utilities. We added features based on our research needs. Our created application is a little bit different from a professional approach. Various display formats are available in our GUI. That makes a difference in the originality of this work. Our GUI can be master, slave, server, or client, which is rarely available. Paper Type: Experimental-based Research.

In a networked virtual world, interconnected participants are able to enter a dialogue and to interact with one another; they cannot actually do so, however, with the remote participants, but rather with the interpretation and representation of the data transferred from the remote site(s). The process of the evolving dialogue in such tele-immersive scenarios is complexly interwoven with another liquid, hybrid and oscillating process, that of ‘becoming a subject’. The actual opacity of the individual sites – in that all sources, such as the participants’ appearance, their input and in fact anything connected to the actual and physical site are only represented on the ‘other site’ – holds something ambiguous, almost uncanny, opening the scope of something third, other, in between. This article addresses the issues of disguise inherent to tele-immersive virtual environments and communication; it examines the issue of presence emerging from the interrelationships between the networked participants, their virtual representation and the underlying computer-controlled system, as well as between the virtual place and the physical location. The issue of presence and embodiment in tele-immersive virtual environments differs from other virtual social spaces, such as chat rooms and current forms of online-games, in the human-scale, three-dimensional representation of the space and the user's manifestation – the so-called avatar. One of the main purposes of networking such virtual environments is the visual and acoustic representation of remote participants as they share the same virtual space with one’s Self, and thus create a virtual meeting place somewhere in between the participants’ remote locations. In such an environment, the tele-dialogue evolves based on an almost absurd scenario of disguise: while, locally, one is limited to communicating with an electronically masked opposite, this form of dialogue also implies that one’s Self only appears to our ‘human’ opposite as its computer graphic incarnation, an avatar – with which one is nevertheless identified. In a typical example of a networked scenario, multiple copies of the environment, as well as the representations of the users (avatars) are displayed at all client sites. Yet the fact that all modes of representations appear as an exact duplicate on the ‘other side’ does not represent a system-inherent condition, but is exclusively based on the intention of the programmer/designer and/or a convention shared by users of the tele-immersive environment. One possible reason for this common convention might be found in the primary impetus behind the development of virtual reality technologies, which is the most indistinguishable and controllable electronic replication of our physical reality and its inhabitants. Assuming, however, that the shared data is based on mathematical descriptions and instructions, their form of interpretation and representation is entirely subject to the modality of the program/system – and thus, in most cases, also to the individual system of each remote recipient (client). How an environment is represented remotely and how users (avatars) appear and behave on each client’s site is thus the expression of a (possibly selected) option, whereby the convention of reproduction is only one possible choice. As the temporary inhabitants are not actually able to enter the ‘other’ remote site, the virtual environment likewise cannot extend to another, remote place, but rather is generated at each local site (a server’s location, respectively). Decisions about the extent to which the data content can be reinterpreted, and in which form it is represented, establish political and hierarchical structures. Centralized network architectures, like the ‘master-slave’ model or the ‘server-client’ model, also shape our virtual architectures of communication. The politicization of the virtual terrain is thereby partly inscribed by the environment’s author and partly emerges from the opaque, disguising nature of each remote system’s signal- and data-processing. The author defines whether the participants are able to choose their own form of representation, how ‘permeable’, in general, the environment is designed to be, to what degree the user can modify its evolution and its outgoing and incoming signals, and the importance attributed to the imagination and identity of the participating co-author. However much the users are accommodated, the implementation of such a representing mediator and translator in between will never result in a ‘neutral’ system. According to the aforementioned mathematical encoding of represented realities, any structure and instruction can be modulated, re-associated or replaced, every single frame. Whether implemented as a time-based, narrative, or independently generative structure, such a potentially nonlinear sequence of dynamic, transformative events is very likely to entangle with the participants’ subjective Self and its formation of identity. For N. Katherine Hayles, Cyberspace opens common construction of body borders for transformative configurations, which always carry the trace of ‘the Other’. The simultaneous estrangement of the self from itself and its cybernetic reconstitution as ‘the Other’ produces a “diffusion of subjectivity” that “constitutes a second mirror stage: the Mirror of the Cyborg." (Hayles 1993, 186) In my tele-immersive installation Maya--Veil of Illusion, the interferences and distortions caused by the system as a third, unknown participant – the allegedly ‘other’ in the system’s own reflection of the participants’ dialogue –gain a strange, ambiguous component. The project translates the Hindu-Buddhist notion of ‘Maya’ (Sanskrit: illusion) into an elastic veil, spanned between two remote, networked sites. The relationship between the Self and the virtual representation of one’s Self and of the other remote participant becomes the cast of something third, other in the virtual layer in between. Although the veil’s distorted mirror image remains the untouchable ‘other’, it spatially materialises the other participant’s presence as it penetrates the electronic filter, occupying one’s private local space. (see figures 1,2 and 3) The combination of immersive, embodying representation, networking technology and a performative, systemic translator in between opens yet another chapter in the concept of ‘suspension of disbelief’ in contemporary media. In a tele-immersive virtual environment, the participants not only deal with a simple feedback loop (between themselves and the environment), but rather with a nesting of loops, in which the other (remote) sides are likewise involved. In other words, the participants pursue their dialogue via the dialogue with the virtual environment and the projection of their Selves. As addressed in Maya--Veil of Illusion, the dialogue between the remote participants becomes entirely mediated – and consequently controlled by the underlying computer system, which might be more or less transparent to the users. Click on image to see figures 1,2 and 3: Maya--Veil of Illusion; local site ingold: EVL, UIC Chicago, remote site in blue: IAO Fraunhofer Stuttgart In their realisation, tele-immersive virtual spaces appear much more introverted than extroverted, in the sense of actually stretching across the multiple remote sites. So it seems that we don’t actually travel to distant places but rather bring them into our local environment – together with the (representations of the) remote users. Both the sensuous experience as well as the process of interacting take place locally, ‘at home'. Thereby, the virtual place doesn’t seem to be able to break away from its physical anchorage and the cybernetic transfer of our Self (still) seems to be somewhat uncanny. The most exciting aspect for remote users is commonly the fact that they are connected to other participants, located in Chicago and Tokyo, physical places they can relate to in their mental world map, rather than the fact that all of them actually – virtually – share the same space. Does this imply that the virtual place and the virtual body, materialised in virtually accessible environments, are coupled with one another in a similar way as we experience the physical and cultural boundaries in our daily life? It seems that space, however, will always rub against the body – in whatever form of reality. Once, during a networking event at the Ars Electronica Center (Linz, Austria) (EVL: Alive on the Grid, Ars Electronica Festival, 2001), connected to Amsterdam, Chicago, and some other remote sites worldwide, I was approached by a participant. “I don’t believe that I am really interacting with all these remote people in Europe and America. How can you prove to me that it is not just a technical fake?” Well, I can’t. Works Cited Hayles, N. Katherine. The Seductions of Cyberspace. Conley, Verena (ed.): Rethinking Technologies.
