In this paper, we present a new simulation platform for complex, radio standard spanning mobile Ad Hoc networks. SimANet - Simulation Platform for Ambient Networks - allows the coexistence of multiple radio modules with different communication technologies and protocol stacks within one node, which can be used concurrently. By the usage of efficient data structures like Randomised Skip Quadtrees, SimANet allows the analysis and evaluation of large scale, heterogeneous network topologies in both static and dynamic simulation scenarios based on different movement models. The software design enables a modular extension with additional models for power consumption, communication complexity or barrier simulation. Furthermore, an integrated MPI library provides the possibility to run distributed test cycles on parallel computing systems. Thereby, special sliding time window algorithms avoid the typical disadvantage of a slow network interconnection structure and allow a dynamic load balancin...
