[ns] help me with the dsr segmentation problem
hi. this is my tcl script to simulate for 3 nodes using dsr routing
protocol. it s givin as segmentation fault. but the same script works for
dsdv just by changin the routing protocol in the script pasted
below...please help me at the earliest as i ve lost a lot of time tryin to
solve this.
the terminal display when i run the tcl script is
[EMAIL PROTECTED] ns-allinone-2.30]# ns simple-dsr.tcl

Re: [ns] Disable ARP
Never mind. The two lines work perfectly. They just happened to trigger another problem, which is taken care of now :) On Tue, 27 Feb 2007 18:27:37 -0500 Ahmad Khayyat [EMAIL PROTECTED] wrote: What is the easiest way to disable the use of the ARP protocol? I guess the IP address corresponds to the MAC address in ns-2, doesn't it? So how do I make the LL/ARP modules use it immediately without using ARP? I tried adding the following two lines at the top of ARPTable::arpresolve(nsaddr_t dst, Packet *p, LL *ll) mac_-hdr_dst((char*) HDR_MAC(p), dst); return 0; but that caused strange behaviour on rare occasions, where a packet suddenly would appear in another far node. Playing with ARP doesn't explain the problem for me, but somehow removing those two lines gets rid of the strange behaviour. So, what is a proper way of disabling ARP? Thanks.. Ahmad
[ns] Multiple interfaces!!!!! Need Help!!!
Hi to all, I am trying to implemt a single node with two interfaces of different technologies: Bluetooth and WiFi. I am a new comer to NS2 and I am finding itquite overwhelming so does anyone have an idea on how I should tackle the problem of multile interfaces given that I use available modules for Bluetooth and WiFi? Also!! Does anyone know about UCBT (an available Bluetooth module) it doesn't have any kind of documentation) so I would appreciate any help I can get on how to use it and any documentation that you have available for it. On the other hand, what about BlueHoc, it runs on ns2.1b7a an old version of Ns2, but could be run on a recent version such as ns2.28 or 2,29 or 2.30, has anyone tried that before?? Did you face any problems?? Thank you for your help I really appreciate it and need it!!

[ns] Segmentation fault with a highly mobile network ??
Hi all, I am trying to carry out some simulations using the ns2 simulator. I have installed the ns2 2.28 and I am using DSR as ad hoc routing protocol. The problem is that with a highly mobile network ( it depends on the pause time fixed when generating a mobility script: setdest -nn 100 -p (pause time ??) ...), a segmentation fault is generated. I have to run consistent scenario: high mobility and long simulation time. Can you please help me about this problem? Thanks in advance!!

[ns] combined wireless and wired nodes in the same simulated topolgy
Hi all,
Is it possible to simulate a wired-cum-wireless network composed by several
wireless nodes that run a given routing protocol and several wired nodes
partially meshed ( not all them are connected to the BS) . Could these wired
nodes use any routing protocol, or there is some contraints or problems for.
I have tried with the ns-2 basic LS protocol . It doesn't function.
The topology is the followin
M1N2
* *
* *
M2 BS * * * * * N1 * N4
* *
* *
M3N3
I activated LS for bstation, sinkNode, sinkNode1, sinkNode2 and sinkNode3
and assigned the relative cost for their links.

$ns rtproto LS $bstation $sinkNode $sinkNode1 $sinkNode2 $sinkNode3
$ns cost $bstation $sinkNode 1
$ns cost $sinkNode $bstation 1

$ns cost $sinkNode1 $sinkNode 1
$ns cost $sinkNode $sinkNode2 2

$ns cost $sinkNode1 $sinkNode3 1
$ns cost $sinkNode3 $sinkNode1 1
$ns cost $sinkNode2 $sinkNode3 2
$ns cost $sinkNode3 $sinkNode2 2

AddrParams set nodes_num_ $eilastlevel
#creates the sink node in first addressing space.
set sinkNode [$ns node 0.0.0]
set sinkNode1 [$ns node 0.0.1]
set sinkNode2 [$ns node 0.0.2]
