Hi,
Do you mean by mobility the speed of a mobile node?
In this case, considering that -m and -M are the options to specify the
minimum and maximum speed of nodes (I don't remember well setdest options),
then setdest will dynamically assign to mobile nodes speed values ranging
from 1 to 6 m/s. If
Hi Faisal,
There's two possibilities to do that in ns. May be, in the examples
you are referring to, source and destination agents responsible of
generating packets are explicitely connected to each other in the tcl
script, making one of them source of packets and the other its
destination for all

Hi,
You can change the nodes transmission range by changing the value of
RXThresh_ of Phy/WirelessPhy by doing :
Phy/WirelessPhy set RXThresh_
A separate C program is provided at
~ns/indep-utils/propagation/threshold.cc to compute the receiving
threshold. You have to compile it, then you can us
Hi,
You can specify node movements using "setdest" utility, which will
generate a file with initial positions and movements of the nodes.
then you have to source this file in your tcl file.
You can find more details in the ns_manuel about that.
Bye.

Hi,
These tcl commands are implemented in Node.cc or MobileNode.cc in the
command( ) method which is used to add tcl commands.

Hi,
You can do that by specifying a port number for your agent and then
attach your agent to the nodes through that port. That way, an agent
can communicate with any other agent by specifying its address and
port id.
Example :
- In .h and .cc files:
#define CLUSTERING_PORT 113
struct hdr_ip *ih
Hi Kathy,
May be all you need is to assign a port number for the ping agent that
you will use when sending packets in your c++ code. Then, in TCL
script, you have to create ping agents and to attach them to nodes
with this port number.
Example :
- In .h and .cc files:
#define MY_PING_PORT 113
Hi,
To specify the communication range of wireless nodes, you should set
an appropriate value of the receiving threshold in the network
interface (in your tcl script), i.e
Phy/WirelessPhy set RXThresh_
A separate C program is provided at
~ns/indep-utils/propagation/threshold.cc to compute the r
Hi,
To have the current positions of a node you need to do :
MobileNode* mnode_;
double x = 0.0,y = 0.0,z = 0.0;
mnode_->getLoc(&x, &y, &z);
You should have mnode_ referencing to a node. For example, in my case I pass
the node address to my agent in the tcl script and for this reason i defined
Hi Dheepa,
One way of reducing the signal range is to set an appropriate value of
the receiving threshold in the network interface (in your tcl script),
i.e
Phy/WirelessPhy set RXThresh_
A separate C program is provided at
~ns/indep-utils/propagation/threshold.cc to compute the receiving

Hi,
You could may be set the parameter delay_ of link layer in your tcl
script like this:
LL set delay_ 10us
Or you could add delay at application layer in your agent before
sending or processing packets using timers.
Hope it helps.
Bye.

Hi,
May be you could replace :
"set ww cwnd_" by " set ww [$your_tcp_agent tcl_method_to_return_cwnd] "
where "tcl_method_to_return_cwnd" is a tcl method defined in the command()
function of tcp class, which returns the cwnd_ param.
Bye.

Hi Ramya,
I'm using ns2.28 and I know that packet headers management changed a
little bit so the Marc Greis Tutorial could not work anymore.
Now, to add you new packet you have to :
- add you packet name to the enum structure containing packet names in
packet.h (under Common directory) (sorry I
Hello,
I've tried to turn off the tracing bu doing in my tcl script :
set AgentTrace OFF
set RouterTrace OFF
set MacTrace OFF
But this does not work, I always get a trace file.
Then I tried to comment the following line:
$ns_ trace-all $tracefile
but I get an error and could not execute the scr
Hi,
You just need to do from your c++ code:
Packet *pk = Packet::alloc();
struct hdr_cmn *chpk = HDR_CMN(pk);
struct hdr_ip *ihpk = HDR_IP(pk);
chpk->addr_type() = NS_AF_INET;
ihpk->daddr() = dest; // the addr of the destination node
ihpk->saddr() = my_index; //cur
Hi Dan,
May be you have to specify the address type in the common header as NS_AF_NONE.
struct hdr_cmn *chpk = HDR_CMN(pk);
chpk->addr_type() = NS_AF_NONE;
...
Bye.
Ps : This is the case for wireless networks, I don't know if it is the
same thing for wired ones.

Hi,
To have current position of a node at agent level, you can do :
MobileNode* mnode_;
double x = 0.0,y = 0.0,z = 0.0;
mnode_->getLoc(&x, &y, &z);
You should have mnode_ referencing to a node. For example, in my case I pass
