...ce of these routing protocols over different mobility patterns that capture some of the characteristics listed above. The mobility models used in our study include the Random Waypoint, Group Mobility =-=[5]-=-, Freeway and Manhattan. To answer Why, we propose some protocol independent metrics such as mobility metrics and connectivity graph metrics. Mobility metrics aim to capture some of the aforementioned...

...tion area, as well as decreases the average nodal speed over time [24, 25]. Recently, there have been a number of mobility models proposed as alternatives to the standard random waypoint model (e.g., =-=[26, 27, 19, 28, 29, 21, 30, 25]-=-). In general, the goal of these models is to increase the realism of random waypoint in particular settings. For example, Hong et al. [28] propose a group mobility model called Reference Point Group ...

However, little work has been done towards using mobility as the basis of clustering in ad hoc networks. In [11], a mobility...
