Mobility modeling is an essential component of wireless and mobile networking research. It assists planning, developing and evaluating protocols and mobile systems. A simulated mobile world provides flexibility for constructing scenarios that closely resemble the real world. Our proposed mobility model emphasizes humans' social roles when making movement decisions. Our model, the Agenda Driven Mobility Model, takes into consideration a person's social activities in the form of agenda (when, where and what) for motion generation. The paper uses a constructive approach to define functional components of the Agenda Driven Mobility Model for building specific real world scenarios and generating motion steps. A variety of real data sources can be used to populate these components. In this sense, the model provides a framework for translating social agendas into a mobile world. In the paper, we utilize National Household Travel Survey (NHTS) information from the U.S. Department of Transportation to obtain activity and dwell time distributions. As an example, we simulate a mobile ad hoc network in an urban scenario, analyzing the geographic features of the network topology generated by the model and the impact of the model on routing performance. Our simulation results suggest that social roles and agenda activities tend to cause geographic concentrations, significantly impacting network performance. We conclude that the incorporation of social agendas into mobility modeling produces a performance evaluation that better reflects real world scenarios.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
