1. Advanced Data Communication Spring 2010

2. Due Date  April 9th, 2010

3. Synopsis  In this project, you will modify the previous project to generate a trace file and analyze the trace file to measure various performance measurements.  Note that this trace file is not the NAM trace file.  The trace file contains a sequence of texts where each line indicates an event of the simulation. For the foramt of the trace file, refer the following web:  http://nsnam.isi.edu/nsnam/index.php/NS-2_Trace_Formats http://nsnam.isi.edu/nsnam/index.php/NS-2_Trace_Formats  Select the same set of simulation parameters as the previous project, and save three trace files with different file names.  The number of lines in a trace file will be so huge that you will not be able to calculate performance measurements manually. Instead, you must write an analysis program in any programming language. For example, C/C++, Java, Perl, Awk, Python, Matlab, etc. There are a lot of online resources for the analysis program, you may need to modify one to demonstrate the following performance measurements:  Throughput  Delay  Probability Density of Delay  Pakcet loss rate  “ns-scan” is an analysis program written by Stephen and his associates. You may use this program and customize it for this project. Note that the source of ns-scan is available on the couse web.

4. 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.

5. 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.
