Abstract

Effective routing in airborne networks (ANs) relies on suitable mobility models that capture the random movement pattern of airborne vehicles. As airborne vehicles cannot make sharp turns as easily as ground vehicles do, the widely used mobility models for Mobile Ad Hoc Networks (such as Random Waypoint and Random Direction models) fail. In this paper, we introduce a novel AN mobility model, called the Smooth Turn Mobility Model, that captures the correlation of acceleration for airborne vehicles across time and spatial coordinates. The model is realistic in capturing the tendency of airborne vehicles toward making straight trajectory and smooth turns with large radius, and is simple enough for tractable connectivity analysis and routing design. We first describe the mathematics of this model and then prove that the stationary node distribution of this mobility model is uniform.
