Radio-Frequency Identification (RFID) systems nowadays have been widely used in various fields such as manufacturing, transportation, health care, etc. In these fields, real-time information collection is usually desirable or even a must, but highly challenging with current RFID systems, because the hardware of RFID tags is too simple to support sophisticated operations. Most of existing information collection protocols are developed for single-reader RFID systems where the whole area is covered by one reader. As the scale of applications becomes larger, more than one RFID reader are needed to ensure the full coverage over the large regions. In this project, we develop two information collection protocols, i.e., Polling Based Information Collection Protocol and Hash Based Information Collection Protocol, for multi-reader RFID systems. The two proposed protocols can coordinate multiple readers to run simultaneously without collision and minimize the time for information collection.
