Abstract

Mobility modeling is important in wireless and mobile networking research due to the fact that few real large scale networks is available for performance evaluation. While existing models only take the geographical movements into consideration, we emphasize in our model the importance of human's social roles. We use a person's social activities to drive and model a node's movements. In this paper, we propose an agenda based mobility model which combine both the social activities and the geographic movements. In the design, we use a constructive modeling approach to allow the model to well conform to the real world and to be easy to use. According to our model, each node moves based on its individual agenda, which includes all the activities (when, where and what) on a specific day. To proceed from one activity to another, a node moves from one road address to another address. In deciding each agenda item, we use NHTS survey data to obtain activity distribution, occupation distribution and dwell time distribution. We use simulation to show the network topology generated by the model and ad hoc network routing performance impacted by the model.
