Architecture for remote laboratories based on REST web services

Abstract

In this paper, a new architecture for remote laboratories based on REST (Representational State Transfer) web services is proposed. The proposed platform use languages such as HTML, AJAX (asynchronous Javascript and XML) and Labview. A web browser is the client interface and on the server side runs an application based on Labview 8.6 with REST web resources. The main contributions are: a) the proposed architecture; b) a "thin client" based on a browser requiring a low bandwidth. Experimental tests, using an analog process simulator, were done and the obtained results show a good performance.

“…Several types of operation that can be performed by the client application on REST web service protocol include GET, POST, PUT, and DELETE [11]- [14]. In this study, JSON(JavaScript Object Notation) is a data format that we use for sending data from a WCF service to the client application.JSON is a data format in the form JavaScript code supported by the REST web service that is used for data exchange, in addition to XML and YAML [14], [15].…”

Current Trends in Remote and Virtual Lab Engineering. Where are we in 2013?

“…A strong indicator for this is that most of the distributed labs are engineering related; teachers from other disciplines who lack an affinity to programming are less likely to provide their labs on the internet since they lack the technical knowledge and support to do so. Most of the existing Labs are tailored lab-specific experiments (for instance: [52][53][54][55] and use diverse proprietary interfaces and implementations but there is no common user interface and no common APIs, nor a common description of them. Despite that, many labs share similar requirements; new experiments require new developments, logic, connectors and user interfaces.…”

Laboratory as a Service (LaaS): A model for developing and implementing remote laboratories as modular components

“…Interactive multimedia can be developed by plugin-based solutions such as ActiveX controls, Java applets, and Rich Internet Applications (RIAs). Recently, several approaches endeavored to shift from plug-in solutions towards native Web technologies such as AJAX, and JavaScript [10,20] in order to achieve maximum compatibility and mobile access. All recent Internet browsers and platforms support Ajax and there is no need to install any software on the client machine.…”

“…A similar approach for controlling instruments online using SOAP Web service is found in [7,8]. In [9], a simple experiment was developed in LabVIEW and delivered as Representational State Transfer (REST) Web service, to be consumed using Asynchronous JavaScript and XML (AJAX) calls. A similar approach based on REST Web service and AJAX is found in [10].…”

“…RELATED WORKS Earlier attempts to deliver remote laboratories as a service can be found in [6][7][8][9][10] . In [6], the functions of commercial instruments based on Virtual Instrument Software Architecture (VISA) and Interchangeable Virtual Instruments (IVI) were listed in Web Services Description Language (WSDL) files and registered in a Universal Description, Discovery and Integration (UDDI) to be allocated and consumed by Simple Object Access Protocol (SOAP) Web service.…”
