“…The WebSocket protocol makes more interaction between a web browser and a server-side middleware possible, and facilitates the real-time duplex data transmission between client-side web apps and the server-side middleware. In addition, the real-time data communications can traverse the TCP (Transmission Control Protocol) port 80 with the WebSocket protocol, which is of benefit for those environments blocking non-web Internet connections by using a firewall [14]. Generally, the WebSocket mainly used to solve several key issues which cause the low transmission efficiency with REST (REpresentational state transfer) and HTTP.…”

“…However, the purposes of WebSock-et are to break the limitations of the request/response protocol such as HTTP [15]. In summary, WebSocket provides an alternative approach to the REST/SOAP (Simple Object Access Protocol)/AJAX (Asynchronous JavaScript and XML) technologies for developing the real-time communication web application, such as, some web-based control applications [14]. Moreover, WebSocket is the next generation method of asynchronous communication between client and server, and is already standardized by the World Wide Web Consortium (W3C).…”

Abstract-Remote laboratory (RL) has become an important component of online education and smart factory due to its capability of remote operation and cost-saving. Recent advantages of information technology have provided various ways to develop RLs. However, how to rapidly bring an offline experiment online is still a vital issue in the development of RL. In this paper, a new flexible framework based on social instant messaging (IM) application architecture is proposed for integrating an offline remote experiment into RL rapidly as a communication node with unique ID. To rapidly connect the LabVIEW controlled devices to server, a new LtoN_UID (LabVIEW to Node.js with Unique ID) module built on Socket.IO protocol is designed and implemented. To demonstrate the effectiveness of this new flexible framework, two existing engineering experiments, i.e., a Smart Vibration Platform (SVP) experiment and a PID motor speed control experiment, are integrated into remote laboratory.

Abstract-With the growing popularity of Information and Communications Technologies (ICT) and information sharing and integration, cities are evolving into large interconnected ecosystems by using smart objects and sensors that enable interaction with the physical world. However, it is often difficult to perform real-time analysis of large amount on heterogeneous data and sensory information that are provided by various resources. This paper describes a framework for real-time semantic annotation and aggregation of data streams to support dynamic integration into the Web using the Advanced Message Queuing Protocol (AMQP). We provide a comprehensive analysis on the effect of adaptive and non-adaptive window size in segmentation of time series using SensorSAX and SAX approaches for data streams with different variation and sampling rate in real-time processing. The framework is evaluated with 3 parameters, namely window size parameter of the SAX algorithm, sensitivity level and minimum window size parameters of the SensorSAX algorithm based on the average data aggregation and annotation time, CPU consumption, data size, and data reconstruction rate. Based on a statistical analysis, a detailed comparison between various sensor points is made to investigate the memory and computational cost of the stream-processing framework. Our results suggests that regardless of utilised segmentation approach, due to the fact that each geographically different sensory environment has got different dynamicity level, it is desirable to find the optimal data aggregation parameters in order to reduce the energy consumption and improve the data aggregation quality.

“…An alternative solution is WebSocket JavaScript interface, which defines a full-duplex single socket connection over which messages can be sent between client and server. The WebSocket standard simplifies much of the complexity around bi-directional web communication and connection management [17]. The problems are the compatibility again and the lack of two-way communication requirements for this particular use case.…”

Abstract-In this paper, we present one model for data sharing in educational classes. Typically, Learning Management Systems present data stores for keeping educational materials as well as the conversations between teachers and students. In our model, we propose a peer to peer data exchange via smartphones. With the high penetration of smartphones across students, the ability to support one-toone communication with teachers could be a good add-on for the traditional learning support systems. This ability could be especially useful for on-demand organized classes, where the standard support is very costly.Index Terms-file sharing, second screen, peer to peer model, cloud services.
