This paper presents the architecture, the system implementation and the performance evaluation of an innovative Internet-based service for object position tracing and tracking (T&T). It supports "full" T&T, as tracking data are not limited only to warehouse check-ins/checkouts, but are extended to the whole transport process, i.e., even when the traced item is on the road, taking...
The current situation in automation is characterised by an ongoing trend towards distributed systems based on intelligent devices, the application of Web services and the usage of Ethernet as the main communication media. The most important standard to deal with distributed control systems (DCSs) is the IEC 61499 whose industrial application is still at the beginning. Within this paper, a platform...
Data access and software exchange are often achieved over insecure networks such as the public Internet. System designers are therefore forced to be proactive with regard to verifying the identity of both human users and software processes that request access to protected resources such as factory data. In this paper we show a new security architecture based upon Web services that supports authentication,...
In the SIRENA project, the service oriented approach is used to connect devices using Web services or Universal Plug and Play (UPnP). In this environment, resources are scarce, and near real time behaviour and high reliability without user intervention is needed. At least in our context an interface design for service oriented architecture should not use a classical object oriented method decomposition...
Collaborative e-commerce provides an increased level of flexibility and dynamicity and generates an entrepreneurial competitive edge. Widely accepted implementation frameworks like RosettaNet may be utilized to provide generic inter-enterprise B2B infrastructure. This paper presents an innovative approach towards utilizing RosettaNet in combination with Web services and ontologies for the enforcement...
