Multiagent testbed for measuring multimedia presentation quality disorders

The capability to deliver continuous media to the workstation and meet its real time processing requirements is recognised as the central element of future distributed multimedia courseware. In this process, user perception of quality of service (QoS) plays an important role. Since people have different expectations we concluded that it is important to ensure that courseware packages meet the user perceived QoS rather than commonly defined QoS. To investigate this hypothesis, we have constructed a multi agent testbed (MAT) for integrated management of resource distribution. We present an overview of the MAT architecture, and discuss a case study in which the MAT is being used to assess the impact of the quality of presentation decline from the perceived QoS on student's learning process.
