[ns] to recuperate a Mobile node coordinates?
Hello; I need some help please. how can I recuperate a mobile node coordinates to use them for my routing protocol? In fact ; I have already included the mobilenode.h (#include mobilenode.h) in my protocolxxx.h file and I put (MobileNode *node_ ) on it (exactly in the constructor) ,I tried to invocate the metod X() so I wrote :( node_ -X() ) ; I have a segmentation fault as a result when I try a TCL .So my second tentative was to use an instance of MobileNode and not a pointer any more what means ( MobileNode node_ ) and the call for the method is ( node_ .X() ) , I do not find a segmentation fault any more but I realize that the coordinates are always equals to 0.0 so I resume that there is a problem. Please ,I need help ,it is an emergency and so important ;it is for my project and I'm in short of time.What files I need to modify (*.h,*.cc,*.tcl or others) Thanks in advance.

[ns] Howto set transmission range ?
Hi, the topic howto set transmission range of a mobile node was discussed in the group previous time. We change the RXThresh (that is calculated by threshold.cc file in ns-2 file hierarchy according to radius) and Pt_ variables in simulation code for changing the value of transmission range. Am I right? CSThresh_ and CPThresh_ variable must be set by us ?

Hello, I am writing to this site because I am interested in receive some information about script TCL. If everyone have some example of script TCL for queueing M/M/S model and M/G/1 model, you could send me on email reporting it. Also, I am interested in example applications of multiple connection nodes of zero queueing to a simple one node. I hope to receive some answer as soon as posible, Thank you in advance.

[ns] Simulating an embedded ad-hoc wireless protocol
Greetings, I have an ad-hoc wireless protocol that has been implemented and fielded in an embedded system. I would like to simulate it for performance benchmarking. My problem is that the code is written in C and it has it's own custom implementation for the MAC, routing protocol, queueing, etc. I have just started looking into ns-2, and from what I understand, it requires the MAC, routing protocol, and message queue to be in seperate classes (inheriting from Agent, Mac, etc.). Is it possible to use ns-2 to simulate a node at the transport layer, and treat the rest as a black box? If not, do you have any suggestions/comments for simulating this firmware? Thanks in advance, Jeff S.

However, whenever I do something like cw_=cw_*5, for example, there is a Floating Exception (core dumped) error. Does anyone know why cw_ may be needed to be modified in a bitshifting manner or how to modify it more simply? Thank you in advance for the help. -Arnab

I think you used a variable Node_(26) in your tcl script but it has not been
created yet.
Look into your tcl script at line 332.

Re: [ns] Multiple simulations in NS
1)First you need to read some books about linux shell program. Then you will
know what is the meaning of #!/bin/sh.
2) That is because your environment variable is not setting properly.
a) you can change your environment variable
The .bashrc file is at your home directory
# .bashrc
# User specific aliases and functions
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
HOME_NS=/usr/local/ns-allinone-2.29
NS_DIR=$HOME_NS/bin
PATH=${PATH}:$NS_DIR:/sbin
LD_LIBRARY_PATH=$HOME_NS/otcl-1.11:$HOME_NS/lib
TCL_LIBRARY=$HOME_NS/tcl8.4.11/library
export HOME_NS NS_DIR LD_LIBRARY_PATH TCL_LIBRARY
b) if you do not want to change your environment variable ,you can use
./yourns2path/ns instead of ns

Re: [ns] Multiple simulations in NS
Another way is through 'for' loop, but make sure you
break up this code (the one to be repeated) as one (or
multiple) subroutines ('procs in tcl') written outside
the 'for' loop.
The code can then be repeatedly called at specific
time intervals using $ns at time subroutine or
proc from a 'for' loop. Time can be incremented
appropriately in each run of for loop.
But you must be careful to set the times (at which the
code is being called as non-overlapping) and the final
'finish' procedure to be called at a time when you
have finished invoking these sub-routines ('procs').
It worked for me, I 'm not sure about your exact
requirements, but you can be able to update the
variables in each run of the 'for' loop as you desire.
BUT be careful while 'for' loops are stable, 'while'
loops take much more effort in coding!
Cheers.
