Abstract
This work proposes context aware handover algorithms for mobile positioning
systems. The algorithms perform handover among positioning systems based
on important contextual factors related to position determination with efficient
use of battery. The proposed solution is implemented in the form of an Android
application named Locate@nav6. The performance of the proposed solution was
tested in selected experimental areas. The handover performance was compared
with other existing location applications. The proposed solution performed
correct handover among positioning systems in 95 percent of cases studied
while two other applications performed correct handover in only 50 percent of
cases studied.
Battery usage of the proposed solution is less than one third of the battery
usage of two other applications. The analysis of the positioning error of
the applications demonstrated that, the proposed solution is able to reduce
positioning error indirectly by handing over the task of positioning to an appropriate
positioning system. This kept the average error of positioning below
42.1 meters for Locate@nav6 while the average error for two other applications
namely Google Latitude and Malaysia maps was between 92.7 and 171.13
meters.
