A major hurdle in evaluating routing protocols for a Mobile Ad hoc NETwork (MANET) is the appropriate modeling of the mobility of wireless nodes. Although the pure random nature of the Random Waypoint model lends itself for theoretical study of MANET protocols, it is not suitable for modeling the movements of mobile nodes in real scenarios. To this end, several entity, group and scenario based mobility models and frameworks have been proposed in literature for representing node mobility. Some of these models cater to only short-term applications of ad hoc networks (e.g., disaster, military), while others are based on complex scenario parameters (e.g., buildings, pathways).
