Modelling Channel Error in IEEE 802.11 Networks
Modeling the performance of IEEE 802.11 networks has been done since the standard first appeared. Most of the models assume saturated traffic conditions and do not distinguish between traffic classes and above all, assume the wireless link to be error-free. Without making any of these assumptions, in this paper the authors illustrate the effect of channel errors in particular on the Quality-of-Service (QoS) in IEEE 802.11 networks. For this purpose the authors developed the own deep simulator and workload generator. The results show that, in the case where the authors had access to hardware test bed results, the results from the model approximate reality reasonably well.
