ABSTRACT: Indoor positioning systems (IPSs) have been intended to provide
position information of persons and devices. Higher user percentage of handheld
devices such as tablets or mobile phones had led to the development of a number
of indoor positioning systems. In this research a work on a real time portable
RFID indoor positioning device such as on smartphone will be performed. The personal
networks will be designed to meet the users’ needs and interconnect users’
devices equipped with different communications technologies in various places
to form one network for better result. Radio frequency identification (RFID)
with directional antenna has proved its potential for locating objects in
indoor environment. Hence, the proposed device idea will be used to exploit
various unknown locations in an indoor environment such as college campus; this
interpretation will rely on Wireless LAN, Received Signal Strength values from
Access Points (AP) in specific mentioned arenas; these APs will be monitored
constantly by RFID with directional antenna (DA) and handheld devices. For
obtaining the better results from existing devices, algorithms of Range
Estimation are proposed, which can be used on various handheld devices for
locating indoor objects.
