This is just for defining node size in nam visualization!

Hello,
You're missing one line of code. To make this work you need to add the
following line to your for loop.
$ns_ initial_node_pos $node_($i) 20
The above line of code is to be the last line of code in the for loop you
have shown here in your email.
Sincerely,

Re: [ns] NAM does not run wireless simulation over ns 2
Hi there,
In a wireless simulation for nam trace you have to use
$ns namtrace-all-wireless $nf $val(x) $val(y)
Hope it works,

Hello to everybody!
I would know your opinion about my solution.
I'm working in MANET routing context and I'm simulating a simple network
made up
by 4 fixed wireless nodes (A,B,C,D) with mac layer 802_11 (dataRate_ set to
11Mb)
and a mobile node (E) with mac layer 802_11 but dataRate_ set to 1Mb that
moves from the
left side to the right side of the network as shown in the next picture:
| A | | B || C | | D |
-| E |-
Now I want to check the data throughput for the communication among node A
and node E and viceversa.
The simulator seams to run correctly but I'm not sure that the current
implementation
of the mac layer mac-802_11.{h,cc} allows me to deal with this scenario,
i.e. it allows me to
use different channel capacities in the same wireless network.
The used simulation script is the following one:

Can you post here your tcl script, that way you could analyse better the results! Luís Barreto On Sat, Nov 15, 2008 at 11:01 AM, coorasse [EMAIL PROTECTED] wrote: Hi all!
