sorry just found out that your deb files did not match because the file is for i386 and im using amd64....did you have another deb files for amd64?

what i mean here was at the global declaration which is in ln10 in scenario2wcett.tcl:

set val(nn) 8 ;# number of mobilenodes

there are two users in CR Network which are licensed and unlicensed users, my project is to evaluate the performance of unlicensed user in the environment among both users.

does this declaration represent node for licensed or unlicensed user?

thank you knudfl

All ns2 is for a 32bits OS.
Some ns2 versions / patches will work on 64bits. Some will not.
Solution : Use a 32bits OS.

# 32 . Sorry. Not something I have any knowledge about.

owh..its ok,
so, to make the ns2 run perfectly i need to change into 32bit OS? is that why im getting segnentation fault when i run ns2 with node 8?

A 64bits OS is always problematic with ns2. If anything works at all.

CRCN : Do not expect it to work on a 64bits OS.

And if you have no scientific applications that only works with 64bits,
there is no reason to use a 64bits OS.

hi there, once again
may i ask you something? for example:

i had a scenario on node=2 with increasing power level starting with 0.03 until 0.30 (increment by 1 each: 0.03, 0.04, 0.05,...,0.30), and then i run the tcl script. based on throughput that i get, avg throughput still 0.00 even i increase the power level. why does it happen?

the other node eg: node 4 or 6, i get different avg throughput everytime i run the script.

thank you in advance

does anyone knows what is the default value of power level in CRN?

is this the right command to use it:
Phy/WirelessPhy set freq_ 2.4e+9
Phy/WirelessPhy set Pt_ 0.40 ;#power level
Phy/WirelessPhy set CPThresh_ 10.0 ;#collision threshold
Phy/WirelessPhy set CSThresh_ 5.011872e-12 ;#Carrier Sense Power
Phy/WirelessPhy set RXThresh_ 5.82587e-09 ;#Receive Power Threshold

thank you for helping in advance
