Recently, researchers have discovered that many of social, natural and biological networks are characterized by scale-free power law connectivity distribution and a few densely populated nodes, known as hubs. The authors envision that wireless networks are directly deployed over such real-world networks to facilitate communication among participating entities. Here nodes move in such a way that they exhibit scale-free connectivity distribution at any instance, which cannot be modeled by most of the prior mobility models. This paper proposes Clustered Mobility Model (CMM), which facilitates in forming the clustering of nodes in a network.
