New Developed Traffic Generator for NS-2

In this paper, a new version of the traffic generator script “cbrgen.tcl” to the Network Simulator (NS-2) was developed and applied in many simulation experiments. The main objective of this paper was to study the impacts of varying the transmitted (sent) data rate for the CBR and TCP traffic under varying number of nodes. The performance of MANETs traffic pattern was evaluated with respect to the quantitative metrics such as PDF, packet loss, throughput, end to end delay and NRL. As a result of this study with the comparative performance between the different data rates of CBR and TCP traffic over varying number of nodes shows a better performance in smaller rates.
