In mobility management, the Random waypoint model is a random model for the movement of mobile users, and how their location, velocity and acceleration change over time.[1] Mobility models are used for simulation purposes when new network protocols are evaluated. The Random waypoint model was first proposed by Johnson and Maltz[2] It is one of the most popular mobility models[3] and the "benchmark" mobility model[4] to evaluate other Mobile ad hoc network (MANET) routing protocols, because of its simplicity and wide availability.

In random-based mobility simulation models, the mobile nodes move randomly and freely without restrictions. To be more specific, the destination, speed and direction are all chosen randomly and independently of other nodes. This kind of model has been used in many simulation studies.

Two variants, the Random walk model and the Random direction model are variants of the Random waypoint model
