Proposed patch for initializing m_numDevices
Attached is a patch to initialize m_numDevices. So, GetNDevices returns the correct value.
Thanks!

Created attachment 3127 [details] Modified script from examples/wireless/wifi-spectrum-per-example.cc Hello, I was working with the LTE module (MultiModelSpectrumChannel) and I was trying to get the number of devices connected to the channel using (GetNDevices) and I obtained some unreasonable numbers. So, I ran another test using a modified version of a script from the examples/wireless folder (wifi-spectrum-per-example.cc). My modified script is attached (wifi-multi-model.cc) and when I run it, I get the following output: distance: 50m; time: 10; TxPower: 1 dBm (1.3 mW) index MCS Rate (Mb/s) Tput (Mb/s) Received Signal (dBm) Noise (dBm) SNR (dB) 0 0 6.50 5.77 7414 -79.74 -93.97 14.22 Devices: 139641248762746 1 1 13.00 11.58 14892 -79.74 -93.97 14.22 Devices: 67 2 2 19.50 17.38 22357 -79.74 -93.97 14.22 Devices: 34 The number of devices (GetNDevices) should be 2. However, as you can see above, Devices (GetNDevices) has different numbers. I saw this issue in ns-3.28 and I also checked whether this has been addressed in ns-3-dev but it has not. I ran my test using Ubuntu 16.04.4 and gcc/g++ 5.4.0 By initializing m_numDevices (0) in the constructor, I obtained what it is expected (2 devices), as shown below. distance: 50m; time: 10; TxPower: 1 dBm (1.3 mW) index MCS Rate (Mb/s) Tput (Mb/s) Received Signal (dBm) Noise (dBm) SNR (dB) 0 0 6.50 5.77 7414 -79.74 -93.97 14.22 Devices: 2 1 1 13.00 11.58 14892 -79.74 -93.97 14.22 Devices: 2 2 2 19.50 17.38 22357 -79.74 -93.97 14.22 Devices: 2 Thanks!
