+1, go ahead... or not. Also the network topology is outdated. Please fix that as well... and maybe check if the explaining part shall be updated as well. BTW, this change should go into the portuguese translation as well :P T. (In reply to comment #1) > +1, go ahead... or not. > > Also the network topology is outdated.

Following the tutorial further, I found some more inconsistencies. The tutorial says - """ We have configured Wifi for all of our STA nodes, and now we need to configure the AP (access point) node. We begin this process by changing the default Attributes of the NqosWifiMacHelper to reflect the requirements of the AP. mac.SetType ("ns3::ApWifiMac", "Ssid", SsidValue (ssid), "BeaconGeneration", BooleanValue (true), "BeaconInterval", TimeValue (Seconds (2.5))); In this case, the NqosWifiMacHelper is going to createMAC layers of the “ns3::ApWifiMac”, the latter specifying that a MAC instance configured as an AP should be created, with the helper type implying that the “QosSupported” Attribute should be set to false - disabling 802.11e/WMM-style QoS support at created APs. We set the “Beacon-Generation” Attribute to true and also set an interval between beacons of 2.5 seconds. """ But the file examples/tutorial/third.cc only contains the first two lines - mac.SetType ("ns3::ApWifiMac", "Ssid", SsidValue (ssid)); This results in the tcpdump output generated by the file being substantially different than that shown in the tutorial after 2.011767 seconds. While looking at the history of third.cc, I found that those lines were removed from third.cc while fixing bug 843 (https://www.nsnam.org/bugzilla/0). I haven't studied wireless networks yet (i.e. I didn't quite understand the discussion on bug 843), so I am not sure if I am the right person to update the explanation. I agree and will fix these in the next day or two. changesets: a27e716d01d9 and 279b0a88b82f (tutorial-pt version) |
