Click the Run icon located on the toolbar. Simulate the Effect of Downlink-Uplink Ratio for Cognitive Radio example.Transport Protocol is set to UDP instead of TCP. Destination with Packet Size remaining 1460Bytes and Inter Arrival Time remaining 10000µs. A CBR Application is generated from CR-CPE-2 i.e., Source to Wireless Node 5 i.e. Right click on the Application icon present in the top ribbon/toolbar and select Properties.Ī.Channel_Characteristics drop-down list is set to NO_PATHLOSS. The Link Properties pop-up window appears.ī. Right-click the wireless link between Base_Station_1 and CR_CPE_2 and click Properties.

See that by default, NetSim has not enabled Path Loss for the wireless links between the Base Station and the CR_CPEs. The following figure illustrates the CR_Bs pop-up window and the default settings. DL_UL_Ratio drop-down list is set to 1:1.Į. Click PHYSICAL_LAYER in the right area see Figure 4-11.ĭ. Click INTERFACE_1 (COGNITIVE_RADIO) in the left area.Ĭ. Right-click Base_Station_1 and click Properties. See that by default, NetSim has set the Uplink to Downlink ratio to 1:1.

See that by default, NetSim has set a grid length of 500m X 500m.

The following network diagram illustrates what the NetSim UI displays when you open theexample configuration file Figure 4-10. Open NetSim and Select Examples > Cognitive Radio Networks > Effect of DL UL Ratiothen click on the tile in the middle panel to load the example as shown in below screenshot To simulate the example Effect of Downlink-Uplink Ratio for Cognitive Radio, in NetSim:

The unicast application transmits data at a constant bit-rate from CR_CPE_2 to Wired_Node_5.

NetSim uses the following defaults for this example:

A network with 1 base station, 1 router, 1 Wired node and 2 CR CPEs, and a unicast application running on one of the CR CPEs.
