ABSTRACT
In the simulation environment to test a new protocol for an ad hoc network, a mobility model needs to be used for representing the movements of the mobile nodes (mobile nodes) that will properly utilize the given protocol. These models play a vital role in determining the protocol performance in MANET. Hence, it is essential to study and analyze the effects of various mobility models on the performance of the MANET protocols. Using a mobility model we try to mimic the real movements of the nodes using a particular networking scenario. The mobility models were primarily designed for representing the movement pattern of mobile users, and how their location, velocity, and acceleration change over time. The mobile nodes are inherently dynamic in nature and different kinds of mobility models have been proposed in order to capture various features of mobility of the nodes.
In the simulation environment we use the mobility models to describe the movements of the mobile nodes. They define the position, speed, and acceleration of the nodes at every moment in the simulation scenario. Based on the dependence of the movements, these mobility models can be classified in
