These models play a vital role in the design of Mobile Ad Hoc Networks(MANET).
Most of the times simulators play a significant role in testing the features of mobile ad hoc networks.
As the mobile nodes move in different directions, it becomes imperative to characterize their movements vis-à-vis to standard models.
Thus these models contribute significantly while testing the protocols for mobile ad hoc networks.
The input to analytical mobility models are simplifying assumptions regarding the movement behaviors of users.
