I will understand no reply as no support for infrastructure WLANs in NS2. Moreover, I have found this text in google:
Bugs in NS2 Simulators always need assumtions to make their calculations viable. However, when some assumptions are crucial in your simulations, you must be careful. For example, there is no scanning for WLAN (Discovery/Select/Authentication/Association) in NS-2, mobile nodes are associated with their BS automatically if they have the same pre-defined domain. If you want to study the overhead of scanning, you should make your extension. ...but also I have found this in a IEEE paper: Abstract—This paper presents an analytic model for computing the capacity of an infrastructure IEEE 802.11 WLAN enhanced with the support of the bidirectional MAC frame aggregation...Simulations with ns2 are performed and the simulation results show that ... So, it seems someone has performed some work in this area. Please, Does someone know about the existence of works in this area? Thank you!
