The mold mobility model for mobile wireless networks

In mobile wireless networks, the network performance is expected to be highly correlated with the mobility pattern of mobile hosts. In this paper, we propose a new mobility model called the mold mobility model different from existing entity and group mobility models in which the movements of mobile hosts are respectively independent and dependent of each other in both the temporal and the spatial domains, the mold mobility model defines the spatially dependent but temporally independent movements of the mobile hosts from the same group. Based on the mold mobility model, a Markovian approach for the analysis of the model is provided to characterize the movements of mobile hosts. In particular, the spatial distribution of mobile hosts is derived for each of the logical groups. Then, validation from simulation also demonstrates the accuracy of the analytic model finally, based on the results, a baseline for the determination of bandwidth allocation in wireless network planning is obtained.
