Applying stochastic network calculus to 802.11 backlog and delay analysis

Abstract

Stochastic network calculus provides an elegant way to characterize traffic and service processes. However, little effort has been made on applying it to multi-access communication systems such as 802.11. In this paper, we take the first step to apply it to the backlog and delay analysis of an 802.11 wireless local network. We found the derived bounds are very loose in comparison to ns-2 simulation results especially for heavy arriving traffic, indicating that improvements are needed for the current version of stochastic network calculus.
