Re: [ns] installing ns2.29
hi all i finally installed ns2.29 on FC6. i just used from ns2.29.3 instead of ns2.29 :-) and it installed without any error. in ns2.29 i received this error: "checking system version (for dynamic loading)... ./configure: line 7624: syntax error near unexpected token ')' ./configure: line 7624: ' OSF*)' regards, elahe - Park yourself in front of a world of choices in alternative vehicles.

[ns] Need help coming up with script for scenario
Hi everyone... Pls I'm working on a project which involves carrying out experiments on a VoIP core network...based on QoS performance metrics...jitter, latency, bandwidth consumption, e.t.c I wanna connect 3-4 WAN models to the core network... The core network consists of routers which routes packets amongst the different WANs... Pls can someone give me or suggest a tcl script depicting VoIP traffic in such a scenario? I'm carrying out a perfomance evaluation between ATM core network and Gigabit Ethernet core network...using QoS parameters as performance metrics Thanks. regards, Brenda

[ns] URGENT: Problem using Rayleigh/Ricean Model
Dear NS Users:
In my simulation, there are two wireless nodes MR and MH. The sender (FH) is
connected to the Base Station (BS). The BS is connected to MR via wireless
link. MR in turn connected with MH via wireless link. So, any packet
transmitted from BS must go through MR and MR will forward the packet to MH.
I am using Rayleigh fading model (or Ricean model) for the wireless
channels. Unfortunately, the packets from BS are directly received by MH
without needing to go through MR. If i use tworay/shadowing models then
there is no problem. But I have to use Rayleigh fading model (or Ricean
model). I am attaching the code here. Please help.
Thanks in advance
Regards

hi.. does anybody have a sample script that can calculate packet S/R/D/F, delay, throughput, jitter and etc for each node for ..tcl/ex/wireless.tcl. All of the sample script just calculate the sum of the packet, not for each node. many thanks.. My system : FC 6 2.6.18-1.2869.fc6 ns2.30 - Fussy? Opinionated? Impossible to please? Perfect.
