ABSTRACT
In this work we propose, implement, and evaluate Group Regularity Model (GRM), a novel mobility model that accounts for the role of group meetings regularity in human mobility. We show that existing mobility models for humans do not capture the regularity of human group meetings present in real mobility traces. We characterize the statistical properties of such group meetings in real mobility traces and design GRM accordingly. We show that GRM maintains the typical pairwise contact properties of real traces, such as contact duration and inter-contact time distributions. In addition, GRM accounts for the role of group mobility, presenting group meetings regularity and social communities' structure. Finally, we evaluate state-of-art social-aware protocols for opportunistic routing and show that their performance in synthetic traces generated by GRM is similar to their performance in real-world traces.
