Abstract
Human mobility models are key components of various research fields including transportation, mobile networks, disaster management, urban planning, and epidemic modeling. Understanding human mobility has a major role in the realistic evaluation of new approaches to challenges in these fields. For the perspective of networked systems, simulations of the networks with human participants such as opportunistic social networks are highly dependent on human mobility. In this article, we summarize the state of the art for scientific research on human mobility and survey the currently used human mobility models. We discuss the commonly used metrics and data collection techniques. Furthermore, we include a taxonomy of the mobility models according to their main characteristics and classify them. We lastly discuss the general trends, applicability, further research directions and open problems of human mobility modeling.
Highlights
Realistic human mobility modeling has great potential benefits to societies
For an opportunistic social network which consists of smartphones, intercontact times of the nodes vary with the movement of the smartphone owners
Based on the observation of the entropy in individual human mobility trajectories, they find the maximum predictability max for each individual which shows the future whereabouts of the person. max represents the fundamental limit of predictability
Summary
Realistic human mobility modeling has great potential benefits to societies. Traces generated by human mobility models can be used in the simulations of wireless ad hoc networks [1], epidemics, urban planning, transportation systems, and disaster response. The second target aims for researchers and developers to understand human mobility modeling in-depth to build their models based on the current state-of-art For this purpose, the article provides an in-depth look at the main findings of the scientific research on human mobility analyses and technical features of the human mobility models. A recent survey by Hess et al [16] is related to the engineering aspects of mobility modeling and data-driven processes of mobility model creation for mobile networks. Our survey presents a comprehensive classification and technical background with a specific focus on human mobility models It essentially provides a different perspective and classification based on emerging research areas of pedestrian mobility, vehicular networking, social networking, and disaster management.
