%X Mobility affects routing protocol performance
within a Mobile Ad Hoc NETwork (MANET). Past research on
mobility models and framework was motivated by the need to
provide a simulation platform for evaluating routing protocol
performance via realistic scenarios. Mobility information of
individual nodes has also been used to improve routing decisions
(e.g., choice of next hop, link break prediction) in a MANET.
In this paper, we introduce a novel concept of integrating
macro-mobility information obtained from the sociological movement
pattern of mobile MANET users, into routing. The extraction
of this mobility information is based on our observation
that the movement of a mobile user exhibits a partially repetitive
?orbital? patten involving a set of ?Hubs? in practise. This partially
deterministic movement pattern is both practical and useful in
locating nodes and routing packets to them without the need
for constant tracking or flooding. Leveraging this Hub-based
orbital pattern, we propose a Sociological Orbit Aware Routing
(SOAR) protocol. Through extensive performance analysis we
show that SOAR significantly outperforms conventional routing
protocols like Dynamic Source Routing (DSR) and Location
Aided Routing (LAR) in terms of higher data throughput, lower
control overhead, and lower end-to-end delay.
