REV 2013 - Grid Remote Laboratory Management System: Sahara Reaches Europe

  1. 1. Grid Remote Laboratory ManagementSystem: Sahara Reaches EuropeMohamed Tawfik, Elio Sancristobal, María José Albert, Gabriel Díaz, Manuel CastroElectrical & Computer Engineering DepartmentSpanish University for Distance Education (UNED)David Lowe, Steve Murray, Michel de la Villefromoy, Michael Diponio,Faculty of Engineering and ITUniversity of Technology, Sydney (UTS)
  2. 2. The implementation of practical sessions in engineering education:• Paves the way for students to be familiar with the instruments and thus, with the industrial real-world.• Augment the learning outcomes by strengthening the understanding of scientific concepts and theories.
  3. 3. Remote laboratories facilitates the practical sessions availabilityproviding on-line ubiquitous workbenches unconstrained by neithertemporal nor geographical considerations.
  4. 4. Remote laboratories are those laboratories that can be controlled andadministrated online. They differ from the virtual simulatedlaboratories as they are interacting with physical instruments.
  5. 5. Recently, remote laboratories have been developed at multipleuniversities and adopted in engineering education. Furthermore, someof these laboratories are replicated at many universities such as theelectronic circuit’s remote labs: NetLab, VISIR, and labs based on NIELVIS II.
  6. 6. This was the commence of a new mainstream which advocates a betterremodeling of those laboratories to allow their allocation, sharing amonguniversities, and their communication with other heterogeneoussystems, e.g., Learning Management Systems (LMS).
  7. 7. In this context, numerous sharable educational architectures for remotelabs integration have emerged such asLiLa, Lab2go, ISILab, DCL, WebLab Deusto, iLab (ISA), and Labshare(Sahara).

  11. 11. GOLC: Global Online Laboratory Consortium• The GOLC consortium is focused on promoting the development and sharing of, and research into remotely accessible laboratories for educational use.• The GOLC partners include most of the pioneers in remote laboratories development and deployment. http://online-lab.org/
  12. 12. GOLC: Global Online Laboratory Consortium• The trend in researching within GOLC is to create standard APIs that allows communication with different remote laboratory systems that adhere to this standard.• For instance, users of Sahara could access experiments integrated in iLab and vice versa.
  13. 13. LabShare (Sahara)• Access to more than a dozen types of rigs, with another dozen types under construction, and over 50 individual rigs.• Installed at more than 4 Australian universities.

  20. 20. Challenges in integrating our remote labs within an RLMS such as SaharaThe diversity of interfaces ofcontemporary developed remote labs Web Adminleads to considering creating standardAPI layer for each interface type andthus facilitate their integration in RLMSs. Web Server Lab Admin Custom built OR Embedded LabVIEW Panel Access Portal OR Lab Server Users RDP User Interface
  21. 21. Challenges in integrating our remote labs within an RLMS such as SaharaThere exist a wide variety of technologies for the communication between client-server:  Desktop Sharing security problems • Virtual Network Computing (VNC)very slow • Remote Desktop Protocol (RDP) limited to a single connection  Common Gateway Interface (CGI) performance problems  ActiveX and Java Applets plugins required  Rich Internet Applications (RIAs) plugins required  LabVIEW Web server only with LabVIEW applications  Asynchronous JavaScript and XML (AJAX) the actual trendEach of these solutions have its relative advantages and disadvantages, which arewell discussed in the paper. However, the trend is more shifted towards webstandards such as AJAX and Web services. On the mean time for LabVIEWapplications LabVIEW web interface is the common choice.
  22. 22. Challenges in integrating remote labs within an RLMS such as SaharaLabVIEW is a de-facto standard in remote laboratories development. Taking into account thatother solutions such as RIAs and CGI are no longer preferred as discussed in the first section.Thus, hundreds of LabVIEw based remote labs have been developed at severaluniversities, which have arisen an important question: how to manage and share all these allthese laboratories using RLMSs.
  23. 23. Challenges in integrating remote labs within an RLMS such as SaharaThe solution is to create standard API tointegrate LabVIEW based remote labswithin a RLMS. This is new researchpath of our upcoming work …... RLMS USERS …... …... Lab Servers Equipments Standard API Diferent LabVIEW-based Remote Labs
