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 balancing on the available hardware resources during the runtime. With
the main focus on the evaluation of abstract multi-interface, multi-standard communication
concepts, we compare the functionality and the complexity of SimANet with well-known simulation
tools like ns2-MIRACLE, ns2-NW-Node, OMNet++ and TeNS. Simulation results for different
application scenarios estimate features like versatility, practicality or usability in large scale network
topologies with up to 105 nodes.
