Abstract
Mobility models play an influential role in the simulation studies of mobile ad hoc networks (MANETs). Realism and simplicity are two attractive properties of mobility models, and achieving both together in modeling mobility has been a challenging task. Recently, a framework of moblity models called destination guided mobility (DGM) models for MANETs was proposed. This framework can be used to develop several simple DGM models with increased realism. Connectivity is a fundamental requirement for communication between nodes. In this paper, we investigate the connectivity in two basic DGM models in comparison with the widely used random waypoint (RWP) model. Specifically, first we expand the DGM models development and analysis software tool to include connectivity analysis. Second, we provide the experimental evaluation of connectivity in the two basic DGM models in comparison with RWP model. Finally, through NS2 simulation, we study the performance impact of these mobility models on the Ad-hoc On-demand Distance Vector (AODV) routing protocol - one of the most popular routing protocols for MANET.
