In this paper, we survey the current scenario available in the field of wireless ad-hoc network. The performance of mobile ad-hoc network (MANET) application depends on several parameters like no. of nodes, node density, communication traffic pattern, communicating range of a node, routing protocol, battery power of a node, mobility etc. Out of these mobility plays an important role. There are several types of Mobility model like Random Way Point (RWP), Mobility models with temporal dependency, mobility model with spatial dependency. We provide a discussion on the existing mobility models, their definitions and their limitations along with the simulation done so far in the field of it.
