In mobile wireless networks, the network performance is expectedto be highly correlated with the mobility pattern of mobile hosts.In this paper, we propose a new mobility model called the moldmobility model. Different from existing entity and group mobility models in which the movements of mobile hosts are respectivelyindependent and dependent of each other in both the temporaland the spatial domains, the mold mobility model defines thespatially dependent but temporally independent movements ofthe mobile hosts from the same group. Based on the mold mobilitymodel, 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 thelogical groups. Then, validation from simulation also demonstratesthe accuracy of the analytic model. Finally, based on the results, abaseline for the determination of bandwidth allocation in wireless networkplanning is obtained.
