Summary:

The invasion of Internet in all aspects of human life has led to the development of modern applications for e-business, like e-commerce, e-government, e-learning, e-health, etc. New standards and technologies for e-business, based on the Web services architecture, that includes: XML, SOAP (Simple Object Access Protocol), WSDL (Web Services Description Language) and UDDI (Universal Description, Discovery and Integration) are developed. This initiates the development of distributed applications, based on program-to-program communication. 

Key goal of the project is the analysis of the latest technologies in web services and their integration and adaptation in distributed automation, based on controllers with embedded TCP/IP stack and Web server. For this puprose, a model of information flow and representation in distributed automation systems will be developed, employing the standards of e-business, working on HTTP/TCP. Modules and libraries for integration of Web sevices in distributed embedded systems will be developed and exposed. 

Previous work of the team members in the fields of web services and distributed automation assures the success of the transfer of the e-business technologies in this field. This transfer will provide new opportunities in distributed automation and control engineering. Scientific results are expected to be the base for establishment of virtual research laboratory in the field of computer networks and distributed computing. There the lecturers, PhD and MSc students of TU-Sofia, branch Plovdiv will work in collaboration with researchers from ICCS BAS. The applied results are expected to give the small and medium enterprises new technologies to force their integration to the European market and standards.
