Re: [ns] help ! for increase communication rage to 1600 m
Read the section of transmission models in NS-2 manual. You should check which transmission model (e.g. FreeSpace, TwoRayGround, Shadowing) is in use. You should try to adjust the RXThreah_ using threshold.c as described in the NS manual. regards, Faisal Phitsanu Eamsomboon wrote: My name is Phitsanu from Thailand , I use ns-2 for to do my research . May I trouble you for ask you some question , I try to increase Transmission rage is 1600 m by increase Pt but It still can communicate in 500 m range , How can I increase transmission rage is 1600 m if I use TwoRayGrounf model. How can I calculate , Please recommend me
[ns] Changing NS Unit disk model of radio range
Hi, I am using cmu extension to simulate a wireless-sensor protocol. I believe NS-2 only support unit disk transmission range model. However, unit disk model is not realistic. I wish to have model that has following (1) Each node selects its transmission range (say c) using uniform distribution from say [a, b]. (2) Each node randomly selects few nodes near the border of circular transmission range to be out of range. It is because in practice transmission range is not exactly circular. I need some pointers to start for example, which files I should target to change. I am not able to track so far the right peace of code dealing with transmission range of nodes in NS-2. Hence I will appreciate some guidance here. I hope to have some quick replies. best regards, Faisal Aslam
Re: [ns] Problem installing NS-2
Dear Manpreet, Your cygwin installation is not complete. While installing cygwin you need to install different thing for NS for example perl, X11 etc. They are not installed when you just press defaults. I think in your case X11 or someother similar component is missing. Read this http://www.isi.edu/nsnam/ns/ns-cygwin.html and install everything required in cygwin before installing Ns2. Otherwise it is easier to use unix machine. Faisal Aslam Dear all, I am trying to install ns-allinone-2.1b9a under cygwin I have downloaded ns-allinone-2.1b9a from http://www.isi.edu/nsnam/dist/ns-allinone-2.1b9a-gcc32.tar.gz i have fully installed cygwin on my system But while installing ns-allinone-2.1b9a using ./install command ,it gives the following error when it comes to Bilding Otcl-1.0a8 checking for libtcl8.3... -L../lib -ltcl8.3 checking for init.tcl... ../lib/tcl8.3 checking for tclsh8.3.2... no checking for tclsh8.3... ../bin/tclsh8.3 checking for tk.h... -I../include checking for libtk8.3... -L../lib -ltk8.3 checking for tk.tcl... ../lib/tk8.3 checking for X11 header files checking for X11 library archive checking for XOpenDisplay in -lX11... no can't find X library otcl-1.0a8 configuration failed!

[ns] invalid ommand name AddrParams
Hi,
When I run SPAN (http://pdos.csail.mit.edu/~benjie/span/span_ns.html) then
it gives me following error.
:invalid command name AddrParams
while executing
AddrParams proc addr2id addrstr {
if [Simulator hier-addr?] {
set addressObj [[[Simulator instance] get-AllocAddrBits ] \
get-Address]
return [$addr
PATH and LD_LIBRARY_PATH variables look fine. I have installed tcl8.3.2,
tk8.3.2 ,tclcl-1.0b10 ,otcl-1.0a6 and ns-2.17b.
Any clues?

Re: [ns] How to trace Segmentation fault error(help me!!!!!!!!!!!!!!!!)
You need to use gdb with the core file generated from the segmentation fault. You'll need to do a stack trace to see what function chain you were inside when the bad-pointer access occured. Hi dear friends How can i trace Segmentation fault error in NS? Please help me Thanks in advance -- Amin Irandoost

Re: [ns] while installing ns-2.1b8a i am getting this error please give me solution
This problem comes when you have later version of gcc. If you have gcc 2.95.x then these problems will not come. Furthermore, You can also go in those files and correct them. That means go to the line number specified in error message and replace friend ABC with friend class ABC. However, it is possible that after correcting many files in this way you will get some more *different* kinds of erros. Hence using gcc older version (2.95.x ) is a better solution. I am posting it on the list for others. regards, Faisal Aslam Hi friends , While installing ns-2.1b8a I am getting this problem In file included from trace.cc:44: tfrc.h:116: friend declaration requires class-key, i.e. `friend class TfrcSendTimer' tfrc.h:117: friend declaration requires class-key, i.e. `friend class TfrcNoFeedbackTimer' make: *** [trace.o] Error 1 Ns make failed!
