Is there any implementation of this model in NS3? As the other mobility models mentioned in this: Tracy Camp, Jeff Boleng, Vanessa Davies, "A Survey of Mobility Models for Ad Hoc Network Research", Wireless Communications and Mobile Computing, Wiley, vol.2 iss.5, September 2002, pp.483-502, paper are implemented in NS-3. Any guidelines or help regarding implementing this type of mobility model in NS-3?
