Hello,
I am trying to connect a node called $reader1 to 30 other nodes. I tryed to
write a for statemant but it is not working.
This works: but with two nodes is very simple
$ns connect $reader1 $tag_1
$ns connect $reader1 $tag_2
This is not working:
for {set i 1} {$i $val(nn)} { incr i } {
Thank you very much. It is working now!!

Is there any way to restrict the transmit power (to lower the range) of
wifi nodes ? How can I configure this ?
In my cenario, the wifi nodes have a large range, but I am simulating RFID
tags, so I need to limitate the range.
Thanks

Hello ns-users,
I have two questions about ns, maybe somebody can help me:
1)Is there any ns-2 extension that simulates a RFID system ? (tags and
readers). If the answer is yes, where can I download ?

signal power)

Hello , Rafael
If you try to put send(pktret,0) in a while which run for a random

Please let me know if you make it.

The second way I don't remember exactly but it consists in using the
function reschedule. You can read about these functions in detail in ns2
manual.
Hope it helps you,

Hello Natalya,
I tryed the solution:
srand(time(NULL));
int tempo = rand() % 400 + 100;
Scheduler sch = Scheduler::instance();
sch.schedule(target_,pktret,tempo);
//send(pktret,0
.
If you look a realization of the function send you'll find something
like target_-recv(p).
What's about schedule: this is a timer that executes the same
target_-recv(p) but in some seconds (the third parameter: a delay).

Hello ns users,
Is there any way to trace only some fields, to avoid trace-all option ? For
example, I need only the options: (s/r/d), -t (time), -Ni, -Is, -Id, -Ii.
How can I do this ? My trace files are becoming to large with a lot of
unecessary information.
Thanks for help!!

Pedro,
Just set the destination address to IP_BROADCAST.
It's the best way.

Hello users,
Does sombody know how to can I make a node wait for a reply from another node ?
For example:
Node 1 sends a packet do Node 2. Node 1 can wait 0.5 seconds (for the
reply) before try another request again. If node 2 sends a reply do
Node 1, that's ok. Else , Node 1 after 0.5 seconds

Hello Rafael
How about to use Error Model between those two nodes, then you will get the
dropped packet in the trace file.

Helllo users,
Is there any way to generate a random number between two given float numbers ?
For example, I'd like to generate a number between 0.1 and 0.3.
I'm using the command
double tempo = Random::uniform(0,time_);
But this command requires two int numbers, instead of two float numbers.
How can I change the transmission power to allow 2 nodes communicate
themselves at a max distance of 5m ? How can I calculate the Pt_ value ?
What does a 0.28 Pt_ value mean ?
Thanks
How can I bind a float member ?
For example, when I bind an integer (bind(value_,value_) it works.
When I bind a float (bind(number_,number_) I receive errors.
What can I do to solve this problem ?
