Abstract

We focus in this paper on modeling the integration between streaming and elastic flows in IEEE802.11-based systems. In such a CSMA/CA shared context, both types of flows do not behave in the same way. Streaming flows, characterized by a constant bit rate, are not able to get more than their need; they however suffer a degraded performance when their share is lower than their constant rate. We then model them as non-saturated sources. Data sources are on the contrary saturated ones and share the bandwidth in a fair manner, as given by a Processor Sharing model. In the presence of the two types of flows, a joint model is hence considered at the MAC layer; the results of which, in terms of QoS for streaming flows and service rates for data ones are then fed into a Markovian flow level analysis.
