Workgroup 4 - Test Applications

On this site you get a project overview of the contribution of the University of Mannheim. Its workgroup is focussed on two test applications for SpoVNet, namely Online Games and Video Streaming. So this workgroup develops exemplary applications for practical testing of the realtime behaviour of SpoVNet.

Online Games

The main focus of the online game subproject is to provide a test environment for SpoVNet. Realistic real time traffic is created in order to represent interactive applications, which use an event-oriented infrastructure. Therefore a close cooperation with the Event Observation and Notification in Self-Organizing Networks (EONSON) project of SPoVNet is necessary.

Furthermore algorithms for "augmented reality" have to be integrated and implemented, which use additional real-life information like the position of a mobile phone or PDA in the real world to augment the game scenario.

Video Streaming

In all networks the demand for video streaming is rising. SpoVNet will be no exception. Besides the increasing bandwidth it is the development of new compression techniques, which enables video streaming over various networks. That is why the different MPEG standards are used more and more. SpoVNet is an approach to give the user transparent access to the services desired through heterogeneous networks. In addition video streaming also has demanding quality of service requirements; they differ from those of online gaming because ther is very little interaction while the video is running; on the other hand startup delay should be short, and multicast into subnetworks with different bandwidths should be supported.

So testing SpoVNet for its ability of video streaming is a good complement to online gaming. We intend to make video streaming as easy as watching TV, without confusing the user with network or device details.
