Mobile RFID (MRFID) Reader
Conventional MRFID readers are supposed to have functionalities such as waking up the passive tags, initiating the reading/writing process, tag and reader collision management and communication with local or remote servers [4]. All these are very power hungry processes. Depending on human movement or reading distance, bigger reading window sizes are needed to achieve a 100% detection of the tags, which implies longer active operation time for the MRFID reader. In the proposed architecture, the master-slave reader act as so named “RF Energy Generator” and energizes tags for wake up and operation [8]. Therefore the MRFID reader always faces tags which are powered up and wakened by the slave or master readers. Thus the MRFID reader acts as a passive reader and does not need any wake up procedure to initiate.
