Research Projects
Plusquam
In Plusquam, a web application for quality management in the automotive supplier industry is being created, employing the Agile development paradigm for increased development productivity and usability. Current technologies are used for supporting these goals, e.g. the web development framework Ruby on Rails and web technologies such as AJAX.SIMOIT
Mobile worker of today make use of the further increasing capabilities of mobile devices in order to access information within company networks from client sites or en-route. While technologies are widely deployed against unauthorized access to company networks through communication media, mobile devices may still fall prey to attacks. For preventing intrusions by way of mobile workers' devices these devices need to be integrity-checked before allowing access to company networks. In SIMOIT a prototype was developed that implemented these measures based on Trusted Network Connect (TNC). Unlike similar, but vendor-specific approaches, this prototype allows deployment with the company network infrastructure largely untouched. Project homepageService Maps
In emerging mobile networking environments, finding and selecting connectivity services increases in importance, especially in unknown network environments. Service Maps are intended to satisfy this demand and offer provider and network topology-independent information on network access and higher layer services, such as VoIP. Project homepage
