Ad Hoc Networks: Routing, Qos and Optimization

Appendix 1

The Ad Hoc Networks Simulator (ANS)

 

 

 

A1.1. The ANS Application

To carry out our simulations, we contributed to the modification and improvement of an application by adding the following models:

– TCL script generation for the OLSR protocol and simulation of various possible scenarios.

– Support of new the OLSRQSUP protocol integrated at ns level, with script generation and execution of simulations.

– Integration of nam file generation procedure (the existing application did not allow this).

– The ANS application is compatible with version ns-2.27 and version 2.28 (Figures A1.1–A1.3).

However, for the application to be supported and useable in version 2.28, some modifications to the file /mac/channel.cc are needed.

A1.1. Traces

We added functions that allow tables for the (OLSR/OLSRQSUP) protocol to be established at trace-file level by referring to the script level.

Figure A1.4 shows an extract from a trace file using the OLSRQSUP protocol (Figure A1.5).
