Abstract

In this paper we present a queueing model for a 802.11 wireless LAN under non-saturated conditions. Our model builds on previous work, but additionally takes into account heterogeneous arrival rates. In particular, we consider the case when there are two packet arrival rates in the network, with one set of stations generating packets at the lower rate and the rest generating packets at the higher rate.
