Mobility Model has drawn more and more attentions since its critical role in Mobile Wireless Networks performance evaluation. In the simulation of the mobile scenario using mobility models, the distribution of the node’s location will converge to the stationary distribution after a long time running. Random Waypoint with Base Point (RWPBP) mobility model proposed in [1] aims to model the movement characteristics in catastrophe rescue scenario. In this paper, we study the Node Spatial Distribution of the RWPBP mobility model using simulation to estimate the convergence time. The simulation results show that, when we use the two dimensional RWPBP mobility model for simulation, the results of more than 21000 seconds of the initial simulation time should be discarded to guarantee the stationary distribution.
