This paper deals with realistic modelling of disaster area scenarios, analyses the node distribution, and shows that the specific distribution affects the impact of topology control strategies. We describe existing topology control strategies and specific characteristics of disaster area scenarios. In disaster area scenarios, there is a demand for sufficient topology control strategies due to the heterogeneous average node degree distribution. We evaluate max-degree and nearest-neighbour topology control strategies in a disaster area scenario and compare the results to those in other scenarios. As metrics we consider average node degree, partitioning degree, and asymmetry. Our evaluation shows that existing topology control strategies tend to partition the disaster area networks.
