Abstract
When analyzing dissemination protocols in mobile ad-hoc networks
the underlying mobility model is an important factor because it strongly
influences the performance of these protocols. So far most of the research
only dealt with homogeneous mobility models like the very common Random
Waypoint Mobility Model and the Random Walk Mobility
Model. In this paper we introduce a new model, the Area Graph-based
Mobility Model, which considers the major characteristics of realistic
scenarios like their heterogeneity. By analyzing the results of experiments
using different broadcast protocols and by comparing our model to the
Random Waypoint Mobility Model we examine the characteristics of the
Area Graph-based Mobility Model. Furthermore we show, that in heterogeneous
scenarios you should use adaptive broadcast protocols, otherwise
an efficient dissemination in areas with differing topologies and densities
is not possible.
