Abstract :
This paper deals with the characteristics of multicast push to talk voice traffic sources for disaster area scenarios. The goal is to design models that can be used to assign voice traffic sources to nodes. The modelling is based on an analysis of real-life measurements during a catastrophe maneuver. The analysis shows that about half of all calls originate from the communication head of a talk group. Based on this characteristic, different models are considered. Synthetic distributions of traffic sources for the different models are generated and evaluated by statistical analysis. Finally, the impact of the different models is evaluated in an exemplary simulative network performance analysis.
