The main research focus of the ComNets group at the University of Bremen is performance analysis of communication networks and their protocols. This includes the implementation of prototypes as well as performance studies by mathematical analysis and simulation. 

The usual infrastructure networks such as Universal Mobile Telecommunications System (UMTS), General Packet Radio Service (GPRS) or Wireless Local Area Networks (WLAN) can be employed for the communcication of the Intelligent Container. However an adaquate way of choosing the appropriate system, if several systems are available, needs to be put in place. Furthermore, maintaining connections independent of switching between the underlying services in cases of limited availability is required. The mechanism employed here to solve this challenge is to use Virtual Private Network (VPN) connections on top of the real network connection.
