Error while running the examples in CRAHN - NS2.31

Running the following example

$ ns test-random-topology.tcl 10 128 2

gives the error

num_nodes is set 50
invalid command name "PUMap"
while executing
"PUMap create _o12 "
invoked from within
"catch "$className create $o $args" msg"
invoked from within
"if [catch "$className create $o $args" msg] {
if [string match "__FAILED_SHADOW_OBJECT_" $msg] {
delete $o
return ""
}
global errorInfo
error "class $..."
(procedure "new" line 3)
invoked from within
"new PUMap"

(file "test-random-topology.tcl" line 86)

any idea

hi
my research is related to cognitive radio networks but im stuck in installation process. as i followed these steps

1. Get ns-allinone-2.31.tar.gz and extract it
2. Install git,
3. Clone this repository:
```git clone git://github.com/abdulla-alali/TFRC-CR.git -b CRAHN```
4. You'll end up with a ns-2.31 clone that has the CRAHN module integrated.
Replace the ns-2.31 subfolder (from the ns-allinone file that you already extracted)
with the one you cloned from here.

and when i tried to run ./configure it gives the following error,, plz help me in this regard as i have to submitt my thesis

cognitive/SpectrumManager.o: In function `SpectrumManager::senseHandler()':
SpectrumManager.cc: (.text+0x35c): undefined reference to `Mac802_11::checkBackoffTimer()'
cognitive/SpectrumManager.o: In function `SpectrumManager::transmitHandler()':
SpectrumManager.cc: (.text+0x516): undefined reference to `Mac802_11::checkBackoffTimer()'
collect2: error: ld returned 1 exit status
make: *** [ns] Error 1

i followed the steps in post #2 ,but after 'configure' when i ran 'make' command i got the following errors

cognitive/SpectrumManager.o: In function `SpectrumManager::start()':
SpectrumManager.cc: (.text+0x20c): undefined reference to `Mac802_11::load_spectrum(spectrum_entry_t)'

kindly give me a solution to this as i have to submitt my thesis

Dear kundfl

i followed the steps to install the patch you mentioned, it is installed successfully but when i tried to run the test-3nodes.tcl , it gave me the following error


[maria@localhost bin]$ ./ns test-3nodes.tcl
invalid command name "PUMap"
while executing
"PUMap create _o11 "
invoked from within
"catch "$className create $o $args" msg"

"if [catch "$className create $o $args" msg] {

You are using a wrong copy of "ns", or you have a failed build.

Repeat : No answers unless you specify your OS :
a) The output from the command $ uname -m
b) OS name and version.

Dear kundfl


In my ns2.35 but last part of validation message shows some tests failed

I using Ubuntu 14.04 with 64 bit . I tried to install ns2.35 .Last part of validation message is shown below… How to correct the error..?Is it a dependency problem? How can i correct it? Thanks in advance…….

These messages are NOT errors and can be ignored:

Dear knudfl and guys,

I have installed the CRAHN program with ns2.31 in ubuntu 10.04, succesfully, by following post #3. Then I modify a litte bit the example by adding 2 commands in test-3nodes.tcl, to obtain nam file, as follows.

set namtrace [open test-3nodes.nam w]
$ns_ namtrace-all-wireless $namtrace 1000 1000

I did the same thing to test-random-topology.tcl. Then, I execute ns test-3nodes.tcl and test-random-topology.tcl. I can see the [SENSING-DBG] processes during the execution. Now, I have tr and nam file. However, I have a question, when I check tr file, I only see op 's' and 'D', without 'r' in tr file. I double check it in the nam file by executing nam file. In the simulation, I could not see data packet transmitted from a node to another, .

Please kindly give me explanation for this matter.

Thank you.
