Petri net based performance evaluation of USAIA's bandwidth partitioning for the wireless cell level

An important feature of the next generation Internet will be the ubiquitous access of mobile users dealing with real-time applications. A recently introduced architecture, called USAIA by J. Sokol and J. Widmer (2001), is considered to provide both for realtime traffic, fast handoffs and a high probability for QoS support during movement of the mobile nodes. This paper examines the performance of the wireless cell level of the USAIA architecture with means of a Petri net model. The design allows a detailed investigation of various model parameters. Therefore, the model is able to assist in optimizing the framework in terms of network design, protocol processing, and resource utilization.
