پروژه ایجاد یک گره ساده برای شبکه سیمی با نرم افزار NS2

create a simple node for wired network

توضیحات مقاله:

It’s required to write a Tcl script that implements the following network topology and simulation scenario. A snapshot of the NAM output should be handed as well.

1.calculate/measure the following metrics by processing the output trace file. You can use grep/awk etc to process this information:
* Sequence number vs. Time at n1
* Queue length vs. Time at n2
* Num of dropped packets at n2
2. Consider the following parameters:
* Offered Load: The rate at which CBR traffic is being injected into the network. Express it in kbps (kilo bits per second).
* Packet Loss: The number of packets that were sent by the sender, but didn’t reach the destination. Express it in percentage.
* Average end-to-end delay: If t1 is the time the packet was generated at the source and t2 was the time the packet was received at the destination. Delay of a packet is t2-t1. Calculate average of these values for packets that reached the destination. Express it in ms.
* Throughput: The rate at which bits are being received at the destination? Eg: If 100 packets of size 100 bytes were received in a duration of 100 seconds, we say the throughput is 100 *100 * 8/100 = 800bps or 0.8kbps. Express it in kbps.
use grep/awk etc to process this information for UDP and TCP separately:
* Offered Load vs percentage packet loss
* Offered Load vs Average end-to-end delay
