Mobility models characterize mobile users' movements of location, velocity and acceleration for the difficulty to obtain traces in real world. A classification of proposed and applied mobility models for MANET (mobile ad hoc networks) are given in this article firstly. The probability distribution of nodes is a basic foundation for the theoretic research of mobility models for MANET, such as the work of network connectivity, average path length, network capacity etc. Researchers have found non-uniform node distribution impairs the validity and credibility of many aspects of wireless ad hoc networks, such as protocol evaluation and connectivity, for they are both based on uniformity node distribution assumption. Integral geometry method is employed in this paper to analyze the node probability distribution of random direction mobility model in MANET. The results of this paper provide precise theoretic foundations, simulations and applications of ad hoc network of random direction mobility model.
