Realistic mobility models are fundamental to evaluate the performance of protocols in mobile ad hoc networks. Unfortunately, there are no mobility models that capture the non-homogeneous behaviors in both space and time commonly found in reality, while at the same time being easy to use and analyze. Motivated by this, the authors propose a time-variant community mobility model, referred to as the TVC model, which realistically captures spatial and temporal correlations. The authors devise the communities that lead to skewed location visiting preferences, and time periods that allow them to model time dependent behaviors and periodic reappearances of nodes at specific locations.
