%X A major hurdle in evaluating routing protocols for a
Mobile Ad Hoc NETwork (MANET) is the appropriate modeling
of the mobility of wireless nodes. 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).
