Although the pure random nature of the Random Waypoint model lends itself for theoretical study of MANET protocols, it is not suitable for modeling the movements of mobile nodes in real scenarios. To this end, several entity, group and scenario based mobility models and frameworks have been proposed in literature for representing node mobility. Some of these models cater to only short term applications of ad hoc networks (e.g., disaster, military), while others are based on complex scenario parameters (e.g., buildings, pathways). In this paper, we propose a novel mobility framework called ORBIT. In addition to generating a more practical mobility pattern based on sociological movement of users, ORBIT can also integrate all the work mentioned above into a single framework. The proposed ORBIT framework is applicable to all kinds of wireless networks (cellular, ad hoc etc.) and is also capable of generating different models to suit either short term or long term network mobility in various scenarios. We also propose an Orbit Based Routing (OBR) protocol for MANETs, which takes advantage of the ORBIT framework and outperforms other routing protocols like Dynamic Source Routing (DSR) and Location Aided Routing (LAR).
