| While Mobile Ad-Hoc Networks are generally
studied using a randomized node move- ment model such as the
Random Way-Point model [8], Vehicular Ad-Hoc Networks deal with
street-bound vehicles following a completely different movement
pattern. This resultsamong other thingsin a completely different
connectivity situation and new challenges for data dissemination
or routing/forwarding algorithms. Thus, researchers need a)
suitable movement patterns for simulation, and b) a solid
statistical understand- ing of the connectivity situation
independent of the protocols utilized. In this work, we present a
set of movement traces derived from typical situations on German
Auto- bahns and an elaborate statistical analysis with respect to
movement and connectivity relevant parameters. In addition, we
present HWGui, a visualization, transformation, and evaluation
package developed to study these scenarios. Beside the analysis
capabilities HWGui is able, among other things, to generate
movement files suitable for simulation with ns-2 [10]. |
