RWP Mobility Model is Widely used in regular MANET research as simulation mobility model, Opportunistic Networks is a branch of MANET, with a characteristic that does not guarantee network topology connectivity, this may lead RWP model not suitable as a simulation model of Opportunistic Networks. In this paper, using concept of average degree and average cluster coefficient in complex network theory, the RWP model simulation data and experimental data are compared and analyzed, and author concludes that when the average degree of RWP model is similar to the experimental data, the clustering coefficient have significant differences, so RWP model is not suited to simulation mobility model of Opportunistic Networks.
