The simulation procedure used in the actual project is explained in this chapter. Total eight scenarios are considered in this project for generating the TCP and CBR traffics across the MANETs using different routing protocols. The mobile nodes selected are 200 mobile nodes and the capacity area is of 500X500 meters capacity area. The scenarios are setup with the required setting as required for their simulation the FTP application is selected for the scenarios that generates TCP traffic and the voice application of low quality is selected for the scenarios that generate CBR traffic.

The scenarios 1, 3, 5 and 7 uses the AODV, DSR, OLSR and TORA routing protocols respectively for generating the TCP traffic and the scenarios 2,4,6 and 8 uses the AODV, DSR, OLSR and TORA routing protocols respectively for generating the CBR traffic and the results obtained from the simulation of these scenarios are used for the performance estimation of TCP against CBR in terms of the metrics delay, load and throughput. The next chapter explains the results obtained by these simulations. 

  In this project two scenarios are considered that are scenario 1 and the scenario 2, the TCP traffic is generated using the scenario 1 and the CBR traffic is generated using the scenario 2. These two traffics are established using the Dynamic source routing protocol across the MANET of 200 mobile nodes. The process of generating these traffics across the MANET also includes the application settings and the configuration settings, particularly the File transfer protocol (FTP) application is selected for TCP traffic generating and video conferencing application is selected for CBR traffic generating.

The sections in this chapter explain the actual steps used for completing the application settings and configuration settings. The mobility model used in this project for 200 mobile nodes is the random way point which is set in default even for the wireless LAN server and both scenarios are selected individually with the DES statistics.  For the scenario 1 wireless LAN metrics and TCP for node statistics are selected and for the scenario 2 wireless LAN metrics and UDP is selected for the simulation that takes 150 seconds to run the entire application includes both the scenarios and the results achieved by this simulation are explained in the next chapter.
