Investigation of TDMA solution for the hidden terminal problem (With “ Wavion ” ) Final Report Presentation

Agenda Introduction The application Simulation methodology Test results and analysis Conclusions and recommendations Open issues, Questions and open discussion.

Introduction The hidden terminal problem. The project purpose. The simulation output. Net ’ s throughput. Each machine throughput.

The application C# GUI and scripting input Output files Event driven simulation Use the user manual KISS – easy for usage and for extends

Simulation methodology Definitions – g Assumptions Application sanity and stability Running methodology: Number of runs. Averages Stations locations. Evaluation measures 1 zone. Relatively Evaluation. Median / Total Bandwidth
