Real time positioning over WSN and RFID network integration

Abstract

RFID is a technology allowing tracking objects or people and mainly applied in critical applications including industrial control, personnel access, etc… Nowadays, demands for providing positional information has grown rapidly and RFID positioning technique is emerging especially for an indoor locating as its development and implementation are very fast. WSN gives information about the objects physical conditions that permit to create cost effective services adapted to application needs. Thus, RFID and WSN integration is an emerging technology utilizing both systems advantages making it reliable and efficient. In this paper, we propose real time locating techniques to satisfy the request of mobile expensive medications localization and managing in a hospital environment efficiently using AOA and TOA based on received signal parameter. We implemented WSN and RFID architectures and discussed it by specifying advantages and disadvantages for indoor real time positioning in our healthcare application.
