Next select a traffic source, the available pre-defined applications such as CBR (Constant Bit Rate), VBR (Variable Bit Rate), FTP Generic, VOIP, and Traffic-Gen are listed in the left window under the heading -Applications. Let us create a connection between nodes 3 (source) and 4 (destination), Selection of the source node: Left click the mouse over the arrow selection tool and then left click it over the device symbol for node 3, the color of number 3 should turn to red. The source node generates traffic and transmits to a destination node. Each connection will have a source and a destination node. At any time, there may be several connections active simultaneously in the network. Part 3a: Creation of Application Layer ConnectionsĪfter setting up the network, the next step is creation of application layer connections between the nodes. 3 Figure 4: The nodes connected to the wireless network. A cloud should appear on the canvas area representing this wireless network and the nodes should be joined to this cloud with blue lines representing the newly formed wireless connections (see Fig. Now click anywhere on the area you selected earlier. To connect these nodes to a wireless network, select Toolset -> Network Components -> Wireless Network. Select all of the nodes by using either of the selection tools and left clicking and dragging the mouse around the nodes. To do this we can use the selection tools (arrow or lasso in the View Toolbar). The first step is to select the nodes we wish to add to the wireless network. Figure 3: Random node deployment We now want to add these nodes to a wireless network. Location of a node may be changed by left clicking the mouse on the arrow button then left clicking it on the node and dragging it to the desired location. The Placement Wizard will close and the nodes will be deployed randomly on the grid in the Scenario Designer window (see Fig.
It then asks for a seed value for the random number generator (leave it blank). Figure 2: Node placement 2 We then enter the desired number of nodes we would like in our network. The Automatic Node Placement Wizard will open (see Fig.
To randomly deploy the nodes we go to the Tool menu -> Node Placement. In adhoc networking scenarios it is often assumed that the nodes are deployed randomly on the terrain and we will assume random deployment in this example. Nodes can be deployed manually according to an arbitrary topology by selecting Toolset -> Device -> Default (just a generic node), then clicking anywhere on the canvas area.
This is done in the right hand window, the so-called Canvas Area.
The first step in creating a network is to deploy the nodes. To setup our first network, we will proceed by a simple example of a 15 node wireless network that accesses the channel using the CSMA/CA scheme defined by the 802. 1 Figure 1: A new scenario has just been created. The left hand window has four panels: File System, Toolset, Visualization Control and Runtime Analysis (Toolset panel open). This is where we will deploy the nodes and create network connections. Click Save.Ī grid should appear in the right hand window (see Fig 1). Enter a name for the new scenario (for example, “Example1”). Choose the local directory where you want to save the scenario. Save it in your local folder: File Menu ->Save. Part 3: Setting Up a Network – Basics The first task is to create a new network scenario.
1” icon on the desktop (this option is available only if you chose to install desktop shortcuts during installation).
Double-click on the “QualNet Developer 5. The first step is to open the Developer IDE program.ĭepending on the installation procedure, it can be opened via the start menu or by opening the directory where QualNet was installed. Although networks can be designed and simulated in a command-line fashion as well, we will focus on the Developer IDE package. It can be used to visually design network scenarios and then run simulations of these networks. 0 Developer The QualNet Developer IDE is a GUI program for developing network scenarios that comes with QualNet 5.
