Re: [ns] Send TcL Commands to NS during simulation runtime

The ultimate goal is a way to couple a mobility generator to NS and run them both live. Has anyone yet achieved this, and if so, how. You wil have to use nse (NS emulation) The options I have been working on are: 1. Pause the scheduler and then send events directly to the scheduler stack -- not working well, as the halt command just terminates runtime For this you would have to recode the scheduler, which is what NSE does 2. Setup the Tcl script to read from stdin and then send commands to it -- NS doesn't completely parse the tcl script as is waiting for more input and so never gets to simulation runtime forget it - the simualtion on really starts at $NS run 3. I believe there must be a way to use the emulate mode of NS to send data in through a socket that is interpreted by NS as a command, but haven't a clue where to start on this. first start to put nse to work properly, only then proceed to adding suck socket etc Pedro Estrela http://tagus.inesc-id.pt/~pestrela/ns2 --- Eng.

[ns] code, tools, facilities and debuging helpers in pedro estrela web page (http://tagus.inesc-id.pt/~pestrela)
Hi all,
As such, I've taken this opportunity to describe the most useful code, tools
and facilities that I presnet in my web page which can be used b yNS2 users
in their simualtions. If anybody has any problem using these facilities, do
not hesitate in asking for assistance!
Regards,
Pedro Estrela
http://tagus.inesc-id.pt/~pestrela/
http://tagus.inesc-id.pt/~pestrela/ns2
---
a) A very simple, no frills, Getopt-inspired argument processing, which
supports short arguments in any order and precedence in a very simple way
http://tagus.inesc-id.pt/~pestrela/ns2/contributed_code.html#_Toc147652228
useful for testing many parameters manually., eg:
ns -- -s 10 more args
ns -- -s 10 more args -s 20
being the array opt(speed) changed with the last given argument (-s).
b) Several useful short TCL procs, mentioned in
http://tagus.inesc-id.pt/~pestrela/ns2/contributed_code.html#_Toc147652229
of these I can point as the most useful:
proc static {varname {initval 0}} {
proc incr { name {value 1 } } {
Class instproc instances {} {
Class instproc subclass {} {
Class instproc vars {} {
proc trace_annotate_time { str { doprint 1 } } {
Simulator instproc set-animation-rate { rate } {
c) Hierarchical addresses procs:
I've made a set of helper functions that enabled me to easily convert from
each type of address that a node can have, where the value -1 in an error
/ unk.
## Type | VarNames| C++ type | TCL |
Example | Error / UNK
##
---|-|---||-|--
## Node's handle | N_handle| char * | string |
_o89 | -1
## String HierAddress | N_haddr | char * | string |
1.2.3 | -1
## 32 bit Address | N_iaddr | int | int in string
| 6144
| -1
## Sequential ID | N_id| int | int in string
| 4
| -1
eg: I've made tcl and C++ functions called iaddr2handle(),handle2haddr(),
etc that can be used in sequence anytime that an address conversion is
required in the code (which in my case was very common).
note that that these functions depend on a small modification in
/tcl/lib/ns-lib.tcl Simulator Node {}, to make sure that all nodes (wired
and wireless) get inside the Simulator::Node_ array.
d) the oTCL debugging facilities.
Using the TK support, it is very easy to add the MASH inspector, which is a
powerful oTCL object inspector. (and also the TKCON console, for a nicer
console).
http://tagus.inesc-id.pt/~pestrela/ns2/ns2_with_tkcon_and_tcldebug_screenshot2.PNG
However, note that this only enables debugging at NS zero-time; for run-time
debugging, its required to install the Tcl debugger, with some modifications
of mine described in the last steps of the guide.
I've also got C++ helper and debugging functions in
http://tagus.inesc-id.pt/~pestrela/ns2/files/utils_ns.h
some examples of very useful helper functions for calling TCL code inside
C++, which was very common in my case:
#define CUR_TIME Scheduler::instance().clock()
#define MY_ADDR
Address::instance().get_nodeaddr(addr())
#define TCL_RESULT Tcl::instance().result()
#define PRINT_NODEADDR(X)Address::instance().print_nodeaddr(X)
#define TCL_EVALF Tcl::instance().evalf
// prototypes
int dprintf (const char *format, ...);
int dTCL_EVALF (const char *format, ...);
int dTCL_EVALFr (const char *format, ...);
int TCL_EVALFr (const char *format, ...);

Re: [ns] ns/nam: respresentation problem when definingposition-fixed nodes (NEW question)
I have the same situation.
I solve it by using the same delay in the real simualtion, and use different
delays just for debugging.

It is a good idea, but in my case all the links must have the same delay,

I' tried to add XY coordinates for wired nodes, but nam doesn't support
this

Instead, I achieve the same result by setting the length of the wired

Subject: Re: [ns] ns/nam: respresentation problem when definingposition-
fixed nodes (NEW question)
Hi ns-users,
I learnt that the previous problem can be solved by using 'orient'
method at the link definition. However, this solution is not enough when
defining more complex structures. The next figure shows 4 nodes standing
in the imaginary vertexes of a square, which are all of them connected
to
a master node like it is shown in the next picture:
node(1,0)node(1,1)
(0,100) (100,100)__
\___\__
\___ \_
\___ master
_/(200,50)
_/ _/
/ /
(0,0) (0,100)
node(0,0) node(100,0)
--- What I would like to know is if it is possible (or not) to define
the
geographic position of the nodes when the coordinates of them are known
in
a wired scenario, or other ideas to solve the problem.

Search for CFLAGS (should be around line 90), and change it from CFLAGS = $(CCOPT) $(DEFINE) to CFLAGS = -g $(CCOPT) $(DEFINE) ok, we're done with the editing. now go to your ns-allinone and type ./install. after everything is done, you should have debugging symbols enabled. so, now you recompile your code into ns, and open ns in gdb (gdb ns) and set the appropriate parameters to ns (e.g. your .tcl simulation file), and type run. When the app crashes, type bt to see the stack. you should see plenty of debug information now. let me know how it goes. the way I prefer the most is just add the -g flag information in the make file. That should add the debug symbols and then while running do following ddd ns once ur in graphical debugger, say set args filename ( any other args) run example.tcl that should give you a good graphical display of your code. debugging becomes easy and faster Do you Yahoo!?

[ns] NS tutorial update proposal
Hi You are, of course, 100% correct - the tutorial is outdated and its very confusing to first time users. One problem is that, in general, NS2 users ask much, but contribute little when they have their questions solved - either by the help of somebody, or by their own. Some examples from my personal experience: http://mailman.isi.edu/pipermail/ns-users/2006-June/056015.html http://mailman.isi.edu/pipermail/ns-users/2006-January/053560.html - Regarding this particular topic, what I suggest is to: - create a page about NS2 tutorials in the NS2 wiki, which could be used to detail the important changes for recent versions of NS2 of this, and possibly other tutorials. http://nsnam.isi.edu/nsnam/index.php/Main_Page - the next step would be to port the Marc Greis's tutorial to the Wiki (at first, a simple 1 page per chapter copy would be sufficient), which would be much easier to maintain afterwards. However, in my opinion, major improvements in problems like this will only be possible if more users take the action to contribute. Pedro Vale Estrela http://tagus.inesc-id.pt/~pestrela/ns2/ On 1/11/07, Joachim Fabini [EMAIL PROTECTED] wrote: Hi all, I noticed that section VII of Marc Greis' tutorial is seriously out of sync with the NS 2.30 sources. First, the ping example is now included in the apps directory of the ns distribution (this is worth mentioning in the tutorial text), Second, some functionality has been added to the apps/ping example (e.g. broadcast) and Third, the location, encapsulation and access methodology for some (former) member variables has been changed (improved imho, but with the drawback of not being backward compatible). Specifically the third aspect requires to update the tutorial. Newbies are likely to be confused by the changes and compiler errors when they write their own protocols based on the ping sample as a template. The tutorial ping uses members which are no longer valid - e.g. off_ip_, which was apparently replaced by hdr_ip::access(); the src_ member which apprently was changed to a struct, yielding the former src_ in src_.addr_, etc.). NS is sufficiently complex for newbies, anyhow. ;) I therefore suggest to reflect these changes of the ping sources back to the tutorial, and, in addition, modify the comment on line 55 of the NS 2.30 apps/ping.h file (and cc-file) requesting that future changes be reflected to section VII the NS Tutorial. (The tutorial/examples directory seems to anyhow no longer exist)... Thanks in advance, best regards --Joachim

Re: [ns] looking for FHMIP extension
Hi, thanks for sharing this link. previously, I've tried to contact teh authors directly to get this software, but without sucess. Can you please send me the email of the person that sended you the extension? (to try to get the author's updated emails). I'm building and maitaining a mirror of all NS2 mobility-related software in my page, and I'll shortly add this fMIP extension to it. http://tagus.inesc-id.pt/~pestrela/ns2/mobility.html If anyone can contribute either software, information or tips regarding NS2 mobility, please email me, and I'll add it to this page and give proper credit. I'l also planning to create a __very__ simple mailling list for persons interested in NS2 mobility, to rebroadcast the mobility-related messages that I receive in the NS2 mailing list, to try to create a simple group of persons with this shared interest. To be added to the list, plese send me an email introducing yourself, and your current mobility-related interest in NS2; meanwhile, I'll search for the several dozens of mobility-related messages that I've sent to varios reserachers, to try to form a critical mass of persons to this group (to be removed from the list, a simple email to me will suffice).
