Re: [ns] Help friends !!!
Hi, there is a unique node ID generated by NS2 for the nodes during their creation. it's an int. and since a short int is 16 bits, an int is 32 bits, and a long int is 64 bits. i suppose by acceding the class Node in the c++ hierarchy and setting the int nodeid_ member as short int nodeid_, you will get what u want (NS2 will generate the id as short int (16 bits)). of course you have to recompile...

Hi, I am working in a wire-based topology, and I need each node in the topology to has a unique 16 bits ID. Actually I have a huge number of nodes in my topology. And I will use this 16 bits ID in future work. Is there any way to do this in NS2. Many thanks in advance Eng. Magdy

actually there is some lignes in the code we don't need them. as you can see
the output of this code is a file called topology.scn . the data in the file
is a s follows:
$node_(0) set X_ 500
$node_(0) set Y_ 850
$node_(0) set Z_ 0.
$node_(1) set X_ 500
$node_(1) set Y_ 200
$node_(1) set Z_ 0.
$node_(2) set X_ 524.31925038076895
$node_(2) set Y_ 233.64114958496819
$node_(2) set Z_ 0.
$node_(3) set X_ 806.80107456017333
$node_(3) set Y_ 905.66013283359825
$node_(3) set Z_ 0.
$node_(4) set X_ 429.85253428567785
$node_(4) set Y_ 531.54373938755305
$node_(4) set Z_ 0.
...
this file will be the entry of your real tcl code file. i mean you can inject
it anywhere you want by puting it with in the same folder as your tcl file and
use the command (after the ceation of nodes):
for {set i 0} {$i $val(nn) } {incr i} {
set node_($i) [$ns node]
$node_($i) random-motion 0 ;# disable random motion
}
source ./topology.scn
hope it will help.

[ns] Packet format issue
hi everyone,
is it correct (doesn't induce to errors) to put a dynamic structure in a packet
header, for example in AODV request header put a pointer to a structure str
{node_energy, next} to record the nodes energy along the request path?
thx in advance.
Re: [ns] get a reference to a node from AODV [resolved].
Hi Itishi, thx again for the reply, actually it appears that the problem that i have been stacked in for a month is that the function static Node* get_node_by_address(nsaddr_t); is static so it can be called by itself independently of any object by using the class name and the scope resolution operator, so i can call it from the aodv.cc and then do the rest of the work. thanks .
