In this paper, we propose an enhanced random waypoint mobility model (ERWP) to achieve a good trade off between reality and complexity. ERWP model uses two stochastic processes for speed change and waiting control, which make the movement of nodes smoother and more realistic. Simulation shows that the proposed ERWP model can provide a spatial distribution and movement behavior of a user in mobile region. Keywords: Mobility Model, Modeling and Simulation, Random Waypoint Mobility Model. The most commonly used mobility model in the networking research community is the random Movement pattern of users is of fundamental waypoint (RWP) model, which was originally importance when evaluating the performance of proposed for studying the performance of ad hoc different kinds of algorithms in wireless networking routing protocols by Johnson and Maltz [10]. [11] environments. If the model is unrealistic, invalid and [12] describe the stationary distributions and conclusions may be drawn. Since real movement stochastic properties of RWP model in detail. [13] patterns are difficult to obtain, a common approach Random waypoint on the border model (RWPB) [14] are the is to use synthetic mobility models which can still and Markovian Waypoint Model (MWP) variants of RWP model. In the former, the capture the essential impact of mobility on the waypoints must be uniformly distributed on the protocol performance in .
