In Mobile Ad Hoc NETworks (MANETs), the mobility of the network users can heavily affect the performance of networking protocols because it causes sudden connectivity changes and topological variations. This is even more important in recent promising paradigms proposed in this field, such as opportunistic and delay tolerant networks. For this reason, it is important to understand the characteristics of the user movements in order to properly handle mobility when designing networking protocols for mobile ad hoc networks. In addition, it is highly desirable to have a mobility model that accurately reproduces the user mobility, thus enabling researchers to evaluate, either analytically or by means of simulations, their protocols under realistic mobility conditions.
