Abstract: Wireless communications and networking have had tremendous developments in recent years. Recently, some proposals have been presented in the literature to build hybrid structures out of different wireless systems. The Third Generation Partnership Project (3GPP) will build a standard architecture for collaborative cellular-WLAN systems. Due to the high complexity of mobile networks, the proposed protocols and algorithms for these systems are usually evaluated by simulations. In these simulations, when real mobility is considered, a certain mobility model must be used. A number of mobility models have been proposed for ad hoc networks. The performance of hybrid cellular networks should be evaluated either by simulation or by analytical modeling. Simulations of these networks require special mobility models. In this paper, we propose a mobility model based on the original version of the "random pathpoint", which is applicable in the simulation of the hybrid WLAN / Cellular systems. The performance of the proposed mobility model is analyzed through simulations and analytical modeling.
