TraJECT-3D: Generating Realistic Mobility Traces for Tactical Network Simulation

Free registration required

Executive Summary

The authors present TraJECT-3D (Track and Junction based Exploit over Complex Terrain), a realistic generator of node movement trajectories for simulating tactical Mobile Ad-Hoc NETworks (MANETs). TraJECT-3D models the macro- and micro-mobility of different types of tactical nodes (e.g., soldiers, scouts, vehicles, UAVs) with a bidirectional track and junction strategy. The novel aspects and distinguishing features of their mobility models are: supporting a three dimensional topology which is essential for realistic modeling of tactical scenarios in difficult terrains, and considering variable size group mobility, multiple mission-based formations, and the inclusion of aerial traffic at the macro-mobility level and correlated movements at the micro-mobility.
