This paper presents the results of parallel simulations of mixed networks using the ns-3 simulator. The simulated networks consist of equal number of simple (leaf) nodes and router nodes, which form a small-world network. The active channels in the simulations link pairs of nodes with symmetric source and sink applications. All network traffic is restricted to a single-hop communications. The network partitioning among MPI ranks is accomplished using METIS library. The performance and

Empirical relations are derived for the memory scaling. Further avenues are identified for improvement of the parallel ns-3 simulator.
