摘要：Delay Tolerant Network (DTN) is an emerging networking technology that is widely used in theenvironment where end-to-end paths do not exist. DTN follows store-carry-forward mechanism to routedata. This mechanism exploits the mobility of nodes and hence the performances of DTN routing andapplication protocols are highly dependent on the underlying mobility of nodes and its characteristics.Therefore, suitable mobility models are required to be incorporated in the simulation tools to evaluate DTNprotocols across many scenarios. In DTN mobility modelling literature, a number of mobility models havebeen developed based on synthetic theory and real world mobility traces. Furthermore, many researchershave developed specific application oriented mobility models. All these models do not provide accurateevaluation in the all scenarios. Therefore, model selection is an important issue in DTN protocolsimulation. In this study, we have summarized various widely used mobility models and made a comparisonof their performances. Finally, we have concluded with future research directions in mobility modelling forDTN simulation.
