In this section we are going to further expand our knowledge of ns-3network devices and channels to cover an example of a wireless network. Ns-3 provides a set of 802.11 models that attempt to provide an accurate MAC-level implementation of the 802.11 specification and a “not-so-slow” PHY-level model of the 802.11a specification.
Just as we have seen both point-to-point and CSMA topology helper objects whenconstructing point-to-point topologies, we will see equivalent Wifitopology helpers in this section. Anydesk 10.8 5. The appearance and operation of these helpers should look quite familiar to you.
We provide an example script in our examples/tutorial directory. This scriptbuilds on the second.cc script and adds a Wifi network. Go ahead andopen examples/tutorial/third.cc in your favorite editor. You will have alreadyseen enough ns-3 code to understand most of what is going on in this example, but there are a few new things, so we will go over the entire script and examine some of the output.
Just as in the second.cc example (and in all ns-3 examples)the file begins with an emacs mode line and some GPL boilerplate.
Take a look at the ASCII art (reproduced below) that shows the default networktopology constructed in the example. You can see that we are going to further extend our example by hanging a wireless network off of the left side.Notice that this is a default network topology since you can actually vary thenumber of nodes created on the wired and wireless networks. Just as in the second.cc script case, if you change nCsma, it will give you a number of “extra” CSMA nodes. Similarly, you can set nWifi to control how many STA (station) nodes are created in the simulation.There will always be one AP (access point) node on the wireless network. By default there are three “extra” CSMA nodes and three wireless STA nodes.
The code begins by loading module include files just as was done in thesecond.cc example. There are a couple of new includes correspondingto the Wifi module and the mobility module which we will discuss below.
Autotune beat key finder. The network topology illustration follows:
You can see that we are adding a new network device to the node on the left side of the point-to-point link that becomes the access point for the wirelessnetwork. A number of wireless STA nodes are created to fill out the new 10.1.3.0 network as shown on the left side of the illustration.
After the illustration, the ns-3 namespace is used and a loggingcomponent is defined. This should all be quite familiar by now.
The main program begins just like second.cc by adding some command lineparameters for enabling or disabling logging components and for changing the number of devices created.
Just as in all of the previous examples, the next step is to create two nodesthat we will connect via the point-to-point link.
Next, we see an old friend. We instantiate a PointToPointHelper and set the associated default Attributes so that we create a five megabit per second transmitter on devices created using the helper and a two millisecond delay on channels created by the helper. We then Intall the deviceson the nodes and the channel between them.Gns3 1.3.3 Windows Download
Next, we declare another NodeContainer to hold the nodes that will bepart of the bus (CSMA) network.
The next line of code Gets the first node (as in having an index of one)from the point-to-point node container and adds it to the container of nodesthat will get CSMA devices. The node in question is going to end up with a point-to-point device and a CSMA device. We then create a number of “extra”nodes that compose the remainder of the CSMA network.
We then instantiate a CsmaHelper and set its Attributes as we didin the previous example. We create a NetDeviceContainer to keep track ofthe created CSMA net devices and then we Install CSMA devices on the selected nodes.
Next, we are going to create the nodes that will be part of the Wifi network.We are going to create a number of “station” nodes as specified by the command line argument, and we are going to use the “leftmost” node of the point-to-point link as the node for the access point.
The next bit of code constructs the wifi devices and the interconnectionchannel between these wifi nodes. First, we configure the PHY and channelhelpers:
For simplicity, this code uses the default PHY layer configuration andchannel models which are documented in the API doxygen documentation forthe YansWifiChannelHelper::Default and YansWifiPhyHelper::Defaultmethods. Once these objects are created, we create a channel objectand associate it to our PHY layer object manager to make surethat all the PHY layer objects created by the YansWifiPhyHelpershare the same underlying channel, that is, they share the samewireless medium and can communication and interfere:
Once the PHY helper is configured, we can focus on the MAC layer. Here we choose towork with non-Qos MACs so we use a NqosWifiMacHelper object to set MAC parameters.
The SetRemoteStationManager method tells the helper the type of rate control algorithm to use. Here, it is asking the helper to use the AARFalgorithm — details are, of course, available in Doxygen.
Next, we configure the type of MAC, the SSID of the infrastructure network wewant to setup and make sure that our stations don’t perform active probing:
This code first creates an 802.11 service set identifier (SSID) object that will be used to set the value of the “Ssid” Attribute of the MAClayer implementation. The particular kind of MAC layer is specified byAttribute as being of the ’ns3::NqstaWifiMac’ type. This means that the MAC will use a “non-QoS station” (nqsta) state machine. Finally, the “ActiveProbing” Attribute is set to false. This means that proberequests will not be sent by MACs created by this helper.
Once all the station-specific parameters are fully configured, both at theMAC and PHY layers, we can invoke our now-familiar Install method to create the wifi devices of these stations:
We have configured Wifi for all of our STA nodes, and now we need to configure the AP (access point) node. We begin this process by changingthe default Attributes of the NqosWifiMacHelper to reflect the requirements of the AP.
In this case, the NqosWifiMacHelper is going to create MAC layers of the “ns3::NqapWifiMac” (Non-Qos Access Point) type. We set the “BeaconGeneration” Attribute to true and also set an interval between beacons of 2.5 seconds.
Hunter x hunter full episodes dub. The next lines create the single AP which shares the same set of PHY-levelAttributes (and channel) as the stations:
Now, we are going to add mobility models. We want the STA nodes to be mobile,wandering around inside a bounding box, and we want to make the AP node stationary. We use the MobilityHelper to make this easy for us.First, we instantiate a MobilityHelper object and set some Attributes controlling the “position allocator” functionality.
This code tells the mobility helper to use a two-dimensional grid to initiallyplace the STA nodes. Feel free to explore the Doxygen for class ns3::GridPositionAllocator to see exactly what is being done.
We have arranged our nodes on an initial grid, but now we need to tell themhow to move. We choose the RandomWalk2dMobilityModel which has the nodes move in a random direction at a random speed around inside a bounding box.
We now tell the MobilityHelper to install the mobility models on the STA nodes.
We want the access point to remain in a fixed position during the simulation.We accomplish this by setting the mobility model for this node to be the ns3::ConstantPositionMobilityModel:
We now have our nodes, devices and channels created, and mobility models chosen for the Wifi nodes, but we have no protocol stacks present. Just as we have done previously many times, we will use the InternetStackHelperto install these stacks.
Just as in the second.cc example script, we are going to use the Ipv4AddressHelper to assign IP addresses to our device interfaces.First we use the network 10.1.1.0 to create the two addresses needed for ourtwo point-to-point devices. Then we use network 10.1.2.0 to assign addressesto the CSMA network and then we assign addresses from network 10.1.3.0 toboth the STA devices and the AP on the wireless network.
We put the echo server on the “rightmost” node in the illustration at thestart of the file. We have done this before.
And we put the echo client on the last STA node we created, pointing it tothe server on the CSMA network. We have also seen similar operations before.
Since we have built an internetwork here, we need to enable internetwork routingjust as we did in the second.cc example script.
One thing that can surprise some users is the fact that the simulation we justcreated will never “naturally” stop. This is because we asked the wirelessaccess point to generate beacons. It will generate beacons forever, and thiswill result in simulator events being scheduled into the future indefinitely,so we must tell the simulator to stop even though it may have beacon generationevents scheduled. The following line of code tells the simulator to stop so that we don’t simulate beacons forever and enter what is essentially an endlessloop.
We create just enough tracing to cover all three networks:
These three lines of code will start pcap tracing on both of the point-to-pointnodes that serves as our backbone, will start a promiscuous (monitor) mode trace on the Wifi network, and will start a promiscuous trace on the CSMA network. This will let us see all of the traffic with a minimum number of trace files.
Finally, we actually run the simulation, clean up and then exit the program.
In order to run this example, you have to copy the third.cc examplescript into the scratch directory and use Waf to build just as you did withthe second.cc example. If you are in the top-level directory of therepository you would type,
Again, since we have set up the UDP echo applications just as we did in the second.cc script, you will see similar output.
Recall that the first message, “Sent 1024 bytes to 10.1.2.4,” is the UDP echo client sending a packet to the server. In this case, the clientis on the wireless network (10.1.3.0). The second message, “Received 1024 bytes from 10.1.3.3,” is from the UDP echo server, generated when it receives the echo packet. The final message, “Received 1024 bytes from 10.1.2.4,” is from the echo client, indicatingthat it has received its echo back from the server.
If you now go and look in the top level directory, you will find four trace files from this simulation, two from node zero and two from node one:Gns3 1.3.3 All In One
The file “third-0-0.pcap” corresponds to the point-to-point device on nodezero – the left side of the “backbone”. The file “third-1-0.pcap” corresponds to the point-to-point device on node one – the right side of the“backbone”. The file “third-0-1.pcap” will be the promiscuous (monitormode) trace from the Wifi network and the file “third-1-1.pcap” will be thepromiscuous trace from the CSMA network. Can you verify this by inspectingthe code?
Since the echo client is on the Wifi network, let’s start there. Let’s takea look at the promiscuous (monitor mode) trace we captured on that network.
You should see some wifi-looking contents you haven’t seen here before:
You can see that the link type is now 802.11 as you would expect. You can probably understand what is going on and find the IP echo request and responsepackets in this trace. We leave it as an exercise to completely parse the trace dump.Gns3 1.3 32 Bit Download
Now, look at the pcap file of the right side of the point-to-point link,
Again, you should see some familiar looking contents:
This is the echo packet going from left to right (from Wifi to CSMA) and backagain across the point-to-point link.
Now, look at the pcap file of the right side of the point-to-point link,
Again, you should see some familiar looking contents:Gns3 1.3.3 Download
This is also the echo packet going from left to right (from Wifi to CSMA) and back again across the point-to-point link with slightly different timingsas you might expect.
The echo server is on the CSMA network, let’s look at the promiscuous trace there:
You should see some familiar looking contents:
This should be easily understood. If you’ve forgotten, go back and look atthe discussion in second.cc. This is the same sequence.
Now, we spent a lot of time setting up mobility models for the wireless networkand so it would be a shame to finish up without even showing that the STAnodes are actually moving around during the simulation. Let’s do this by hookinginto the MobilityModel course change trace source. This is just a sneakpeek into the detailed tracing section which is coming up, but this seems a verynice place to get an example in.
As mentioned in the “Tweaking ns-3” section, the ns-3 tracing system is divided into trace sources and trace sinks, and we provide functions to connect the two. We will use the mobility model predefined course change trace source to originate the trace events. We will need to write a trace sink to connect to that source that will display some pretty information for us. Despite its reputation as being difficult, it’s really quite simple.Just before the main program of the scratch/mythird.cc script, add the following function:Gns3 1.3.3
This code just pulls the position information from the mobility model and unconditionally logs the x and y position of the node. We aregoing to arrange for this function to be called every time the wirelessnode with the echo client changes its position. We do this using the Config::Connect function. Add the following lines of code to thescript just before the Simulator::Run call.
What we do here is to create a string containing the tracing namespace pathof the event to which we want to connect. First, we have to figure out which node it is we want using the GetId method as described earlier. In thecase of the default number of CSMA and wireless nodes, this turns out to be node seven and the tracing namespace path to the mobility model would looklike,
Based on the discussion in the tracing section, you may infer that this trace path references the seventh node in the global NodeList. It specifieswhat is called an aggregated object of type ns3::MobilityModel. The dollar sign prefix implies that the MobilityModel is aggregated to node seven.The last component of the path means that we are hooking into the “CourseChange” event of that model. Gns3 1.3 3 Download
We make a connection between the trace source in node seven with our trace sink by calling Config::Connect and passing this namespace path. Once this is done, every course change event on node seven will be hooked into our trace sink, which will in turn print out the new position.Gns3 1.3 3 Free Download
If you now run the simulation, you will see the course changes displayed as they happen.[ < ][ > ][ << ][ Up ][ >> ]
