[ns] How "really" change transmission range
Hi all, I have a problem in a wired-cum-wireless scenario: in my scene, there are 4 Base Station that make a square. The distance betwen 2 BS is 1000 m. I want the transmission range of every BS to be 750m, so that a mobile node doesn' t lose packets when passes from a BS to another. I tried to modify the RXthresh_ parameter in the Phy/WirelessPhy field, according to the program threshold.cc, but in the simulations nothing changes: The mobile node begins to lose packets 200 m past the BS and resumes the connection 200 m before the next BS. In some cases, it resumes the connection 10 m before the BS. So the mobile node moves for 600 to 800 m without a connection and all the packets drop. Then i tried to modify the Pt_ variable. I put it to 1.0, 2.0 and also 20.0. It doesn' t change anything. Then I tried to modify txPower and rxPower of the BSs, I put them to 1000. But nothing changed. So I surrender to the idea that in ns2 the transmission range cannot change. If someone would show me that I am wrong, I would be much obliged. Thanks in advance!

I'm using a nse extension to have some real (UML) machines talking each other
via ns-2. If I use this code I get the error:
[EMAIL PROTECTED] ns2emulation]# ../nse mah.tcl
Using gettimeofday() insdead of the CPU cycle counter to guarantee portability
install nets into taps...

Usually I get this error when something is not correctly linked. If on the UML
machines I set the ARP statically, it's work (I get the error on the
arp-request Who has 10.0.0.2...that is broadcast)
The code than handle this is:
void
RawTapAgent::processpkt (Packet* p, const NodeInfo& srcinfo) {
hdr_cmn* ch = HDR_CMN(p);
hdr_ip* ip = HDR_IP(p);
NodeInfo dstinfo = ((uint8_t*)p->accessdata ());
if (dstinfo.mac () == NodeInfo::broadcast_addr) { //A broadcast packet
ip->daddr () = IP_BROADCAST;
ip->dport () = 0;
TDEBUG5 ("TapAgent: changing the src and dst address to %d:%d
---> %d:%d\n", srcinfo.get_node_addr (), 0, -1, 0);
} else {
nit = lower_bound (nodes.begin (), nodes.end (), dstinfo);
if (nit == nodes.end () || (dstinfo < *nit)) { //Destination
address not found in the map table
Packet::free (p);
TDEBUG ("Dropped packet: invalid destination\n");
return;
}
ip->daddr () = (*nit).get_node_addr ();
ip->dport () = 0;
TDEBUG5 ("TapAgent: changing the src and dst address to %d:%d
---> %d:%d\n", srcinfo.get_node_addr (), 0, (*nit).get_node_addr (), 0);
}
ip->saddr () = srcinfo.get_node_addr ();
ip->sport () = 0;
TDEBUG4("%f: Tap(%s): recvpkt, writing to target: %s\n",
now(), name(), target_->name());
Scheduler::instance().sync ();
ch->timestamp() = now();
target_->recv(p);
return;
}
How can I solve this? Please, I really need a soluzione for this!
If I use the wireless scenario they provided me, all works fine.

[ns] Integrate NS-2 with real network
Hi! I need help about integrate NS-2 into a real network. I would like that a real client communicates with a node within the simulator or with another node external to the simular (eg. a server). I saw the emulator extension, and now I can use ns-2 as a gateway, but I don't know how make real-simulator network communication (can I assign a real IP address to a simulated node? I read that I can't...). I would appreciate any suggestion/link/idea/code!! Thanks, Paolo Carpo
[ns] error while adding new protocol from "NS by example"
Hi all!
I'va a problem when I try to add the Multimedia agent and protocol from "NS by
example (nile.wpi.edu/NS/index.html)". I followed all the steps, but when I try
to run the script I get:
invalid command name "Agent/UDP/UDPmm"
while executing
"Agent/UDP/UDPmm create _o132 "
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

invoked from within
"new Agent/UDP/UDPmm"
invoked from within
"set udp_s [new Agent/UDP/UDPmm]"

Do you have any solution/idea?
Thank you very much!

[ns] R: Problem with emulation
Dear Svilen, You are totally right! Using just one interface, without filtering mac addresses, the simulator enters in a loop. Now it goes well! Thx a lot for the link, my next step will be integrate some UML with ns-2! Have a nice day, Paolo Carpo
[ns] Problem with emulation
Hi list!
I'm having some problems using the emulation examples.
I try to use ns-2 as a forwarder: real host A send a ping to real host B,
passing through the simulator, C. After adding the correct route to A and B to
use C as a gateway, I use this script (because the one with ns-2 doesn't work
at all)
# Inside the simulator
#
# node(5)
# / \
# / \
# node(2) node(1)
set ns [new Simulator]
$ns use-scheduler RealTime
set f [open out.tr w]
$ns trace-all $f
set nf [open out.nam w]
$ns namtrace-all $nf
# Create the nodes
set n1 [$ns node]; #reading from real network
set n2 [$ns node]; #writing to the real network
set n5 [$ns node]; #nothing important
# Configure the entry node
set bpf1 [new Network/Pcap/Live]; # Create the bpf
set dev1 [$bpf1 open readonly eth0]; # Open the device
$bpf1 filter "icmp and host 192.168.0.3";# put the filter
set tap1 [new Agent/Tap]; # Create the Tap Agent
$tap1 network $bpf1; # Connect bpf to Tap Agent
$ns attach-agent $n1 $tap1; # Attach Tap Agent to the node(1)
# Configure the exit node
set ipnet [new Network/IP]; # Create a Network agent
$ipnet open writeonly
set tap2 [new Agent/Tap]; # Create a Tap Agent
$tap2 network $ipnet; # Connect network agent to tap agent
$ns attach-agent $n2 $tap2; # Attach agent to the node.
# Connect the agents.
$ns simplex-connect $tap1 $tap2
#Just for debug
puts "tap1: $tap1"
puts "tap2: $tap2"
puts "Node1: $n1"
puts "Node2: $n2"
puts "Node5: $n5"
puts "bpf1: $bpf1"
puts "ipnet: $ipnet"
# Setup connections between the nodes
$ns simplex-link $n1 $n2 10Mb 5ms DropTail
$ns simplex-link $n5 $n2 10Mb 5ms DropTail
$ns at 10 "finish"
proc finish {} {
global ns f nf
$ns flush-trace
close $f
close $nf
exit 0
}
$ns run
If I run this script, the packets are forwarded, but the simulator begins to
create a very big traffic of dup packet:
...
TapAgent(_o24): sent packet (sz: 60)
TapAgent(_o24): sent packet (sz: 60)
TapAgent(_o24): sent packet (sz: 60)
TapAgent(_o24): sent packet (sz: 60)
TapAgent(_o24): sent packet (sz: 60)
TapAgent(_o24): sent packet (sz: 60)
TapAgent(_o24): sent packet (sz: 60)
TapAgent(_o24): sent packet (sz: 60)

4.835976: Tap(_o21): recvpkt, writing to target: _o13
4.836086: Tap(_o21): recvpkt, cc:60
...
I really don't understand why. And if I use IPTap for the 2 tap I get:
IPTapAgent(_o21): sendpkt called while in read-only mode!
0.770541: IPTapAgent(_o21): recvpkt, cc:1
Thank you very much for any idea/suggestion/tip.
Paolo Carpo
P.S. Sorry for the poor english
[ns] : Found Error in cmu-scen-gen / cbrgen.tcl
Hi, I found an error in the cmu's script to generate traffic pattern. The file is /indep-utils/cmu-scen-gen/cbrgen.tcl My ns version is ns-2.29 Error is in lines 166 and 183: you must change [expr $opt(nn) + 1] with [expr $opt(nn)]. I think that this correction follows directly from basic modular math. In fact without this correction node index, for a set of nn node, has a range from 0 to nn, instead that from 0 to nn-1.

[ns] How can I make a simulation delay in ns2?
- Original Message - From: Yangmx To: ns-users@isi.edu Sent: Tuesday, January 24, 2006 11:41 AM Subject: How can I make a simulation delay in ns2? Hi,every body, I want to delay the simulation time for several seconds in ns2 before sending or receiving a aodv packet. How can I do for that? In the linux C program we can do it by call "sleep(seconds)" easily. Have any things similar to sleep() in ns2? Thanks in advance. michelle
