Completion Talk on My Diploma Thesis / Abschlussvortrag zu meiner Diplomarbeit

Posted on 2009-06-26 13:30 by Timo Bingmann at Permlink with 0 Comments. Tags: ns-3 talk university

Today I gave the final completion presentation for my diploma thesis. The talk showcased a selection of results published in the thesis. Results and experiments are only sketched, as all further detailed information can be found in the thesis PDF itself.

The talk contains side-by-side comparison plots of feature enhancements made to ns-3 and verifications thereof using ns-2. Furthermore, the EDCA extensions implemented in ns-3 are tested against analytically calculated reference values. In the end, a speed test comparison is done between ns-2 and ns-3, which uses the implemented classes to run an experiment scenario identically on both simulators.

The slides are available as PDFs in following two variants:

Presentation Slides (including appendix): ns-3-wifiex-completion-slides.pdf 1455 kB
Presentation Slides (two per page, excluding appendix): ns-3-wifiex-completion-slides-1x2.pdf 1040 kB

Finished My Diploma Thesis on 802.11 in ns-3

Posted on 2009-04-29 17:30 by Timo Bingmann at Permlink with 2 Comments. Tags: ns-3 university

After a very exhausting last week with lots of writing and little sleep, my diploma thesis is finally complete. The thesis is on enhancements to the 802.11 model and EDCA (enhanced distributed coordination access) QoS (quality of service) extensions in the new network simulator ns-3.

The thesis is written in English and a copy of the abstract and table of contents is located below. There is also a Zusammenfassung in German.

It is available as PDF in different variants:

Standard PDF version: thesis-bingmann-ns-3-wifi.pdf (3469 kB)
Better printable version (with black links): in RGB color with binding offset (3482 kB)
in CMYK color with binding offset (3381 kB)

Beyond the thesis itself, an extra page contains additional material like the source code, plot results and a snapshot of ns-3 at that time.

Halftime Talk on My Diploma Thesis / Zwischenvortrag zu meiner Diplomarbeit

Posted on 2009-02-06 17:30 by Timo Bingmann at Permlink with 2 Comments. Tags: ns-3 talk university

For the last three months I have been working intensely on my diploma thesis. The thesis will be about 802.11 enhancements and EDCA QoS extensions in the new network simulator ns-3.

Today I gave my halftime presentation about the current status of my efforts. The talk is composed of a short introduction into ns-3, followed by a detailed discussion of WLAN packet reception criteria and finishes with a review of DCF and how EDCA extends it.

Be warned: many slides are not all self-explanatory and therefore less suitable as a casual introduction into the topics. They are slides meant for presentation.

The slides are available as PDFs in following three variants:

Presentation Slides (including "Animations"): ns-3-wifiex-halftime-slides.pdf 1076 kB
Handout Slides (one per page): ns-3-wifiex-halftime-handout.pdf 1036 kB
Handout Slides (four per page): ns-3-wifiex-halftime-handout-2x2.pdf 1028 kB

Here the table of contents:

  1. ns-3 Basics
    1. Introduction
    2. Showcase: Design Patterns
    3. Current State
  2. Wifi in ns-3
    1. State of 802.11
    2. PHY Layer
    3. Signals, Noise and Interference
    4. Short Recapitulation of DCF
    5. QoS with EDCA
  3. Conclusion
