Application to a warehouse environment of a tracking system based on RFID and free software

This paper presents the modeling and implementation of a tracking and traceability system of products within a warehouse using RFID, Wi-Fi, Android operating system and the EPC standard to optimize the storage/retrieval and picking processes. We propose a client-server system architecture. The client application can obtain the EPC code of an object marked with an RFID tag inside the warehouse and get the approximate location of the object read by the client application by reading Wi-Fi signals obtained by the device running the client application. The application server implements an event and location engine based on the EPCIS Repository application.. The system allows quick and efficient location of products, while implementing artificial intelligence methods to improve productivity during the picking processes.
