PROJECT 1

Advanced Data CommunicationSpring 2010

Due Date

March 19th, 2010

Synopsis

This is a preliminary project to learn a network simulator called NS2. The network simulator is a discrete-time event-driven simulator for network research, widely adopted by academia. You will create five network nodes. Three nodes (S1 to S3) are connected to node M which is in turn connected to node D. The source nodes S1 to S3 continuously send UDP packets of size L bytes to the destination node D thru the middle node M. The time interval between two consecutive packets from each source node is T msec. The link is a duplex link with R Mbps bandwidth and Z msec delay. You will collect timely bandwidth usage of each UDP connection with 1 second interval for at least 60 seconds, and compare their bandwidths. You will select three (3) different sets of simulation parameters from the following table:

Parameter

Parameters

Description (unit) Possible values

L Packet Size (byte) 500, 1000, 2000

T Packet Inter-departure time (msec)

5, 10, 15

R Bandwidth of Links (Mbps) 1, 2, 10, 50

Z Delay of Links (msec) 10, 20, 30

Team

You will form a group of 5 persons. Each group submits ONE copy of the project report, but each member completes a “Peer Rating” form and submits it to the instructor CONFIDENTIALLY.

Submission

You will submit a project report that follows the IEEE conference publication format. The report includes but is not limited to the objective, experiment methods, and result analysis.

All text sources will be included as appendices, containing source files (tcl files) and configuration file if exists.

Simulator

You need access to an NS2 simulator for all projects during this semester.

If you have a Unix account from the School or your own Linux system, you can install a recent NS2.

Unfortunately, NS2 does not natively support MS Windows system.

To MS Windows, you can install Cygwin/X and then NS2.
