Design & development of location identification using RFID with WiFi positioning systems

Localization of an article in a bounded area can be attained by WiFi Positioning System (WPS). WPS is used to identify entities inside the human habitation area using radio waves collected by smart devices. The proposed system focuses to track an individual in a bounded environment. The recognition of the entity can be achieved by Radio Frequency Identification (RFID) transponders. The RFID trackers accomplish fingerprinting with the Unique Device Identification (UDI). The procedure is deployed using an RFID sensor based application which pinpoints the location of the personnel inside architectural frameworks. The position co-ordinates in the indoor area can be using the WiFi technology. The mechanism is split into two sections — Data Collection and Position Identification. The data collection combines the location information acquired from the sensor technologies. The identification of an individual with RFID transponders which results in the tracking of the entity. The location information obtained from the sensors are without time constraints and is updated in the RFID readers and databases including the last time zone. Design and development of the application from connecting to the sensor devices, distance estimation between the sensor devices and the entities, retrieval of the exact position information are deliberated. The pseudo code to connect to the nearest sensor device and obtain the location information is stated. The mechanism of the position estimation algorithm is executed using LabVIEW system design and development software.
