The difficulty to compare network simulators is a major obstacle to the broader adoption of these
tools. This problem particularly affects 802.11 simulators because the 802.11 protocol is complex
and simulators contain several simplifications that are difficult to evaluate. In this paper, we present
a generic visualization system able to interface with the 802.11 protocol implemented in NS-2 and
Glomosim. Our tool allows to emphasize the common behaviours and divergences observed
between the simulators and the IEEE 802.11 standard. Our contribution includes the definition of a
new method to compare simulators and the publication of the most complete list to date of
modeling differences relative to NS-2 and Glomosim lower layers.
