RFID technologies are gaining much attention as they
are attractive solutions to many application domains. Localization
based on active RFID technologies provides a
much needed added-value to further expand the application
domain. LANDMARC was the first attempt using active
RFID for indoor location sensing with satisfactory results.
However, the LANDMARC approach suffers from two
drawbacks. First, it does not work well in a closed area
with severe radio signal multi-path effects. Second, to further
improve the localization accuracy, more reference
tags are needed which is costly and may trigger the RF
interference phenomenon. The proposed VIRE approach
can overcome the above drawbacks without additional cost.
Based on the concept of virtual reference tags, a proximity
map is maintained by each reader. An elimination algorithm
is used to eliminate those unlikely locations to reduce
the estimation error. Our experimental results show that
the new method consistently enhances the precision of indoor
localization from 17 to 73 percent over the LANDMARC
approach at different tag locations in different environments.
