Abstract

This paper present an analytical model for the DCF function in 802.11 Mesh Networks where nodes are not all able to hear each other. The aim is to obtain insight into behavior rather than numerical accuracy. The model is quite general and accounts for the fundamental parameters that affect performance, namely network and flow topologies, channel reservation, exponential backoff and hidden nodes. Performances of the most elementary mesh networks (linear, tree, star,...) are analysed using this model. NS simulations are also provided to compare with the analytic results.
