Abstract
The broad usage of mobiles or tablets as handheld devices has lead to various inventive applications & services which are making their existence felt in daily life. One such application is location tracking in indoor environments. This research will present a real time portable RFID indoor positioning device i.e. for smart phones. To interpret the unknown locations the application will rely on WLANs, exploit Received Signal Strength (RSS) values from neighboring Access Points (AP) that are constantly monitored by the mobile devices, RFID and directional antenna. The broadcasted energy can be used effectively by triggering the antenna to radiate in preference to different directions in which tags are most likely to be found. The idea is to make use of directional antenna which will effect in low power consumption and higher accuracy rate. To issue higher reliability in the process of navigation a method will be proposed to calculate the Quality of Positioning which will provide accurate target locations. Accuracy, precision, efficiency, Environmental factors and Energy Consumption has been taken into study by performing experiments under several conditions to demonstrate effectiveness of the proposed model.
