ABSTRACT
This chapter presents major features of the radio frequency identification device (RFID) technology. It describes related studies on integration of RFID and sensor networks. The chapter provides the several phases of the prototype system. It discusses technical challenges and future improvements. The RFID reader mote software queries the RFID reader simulator every second for tag messages. In response, the RFID reader simulator sends a set of tag messages to the reader mote. The RFID Station module is the main module and handles all the interactions among various sub modules. The RFID Database module handles all database-related interactions. Its main task is to store received tag messages to a persistent storage. The chapter describes the development phase, including the details of the application prototype system, results, and future enhancements. It examines a medicine monitoring and notification system for elder patients without personal care assistants.
