Random Sequence Based Multipolling Method for Collecting Ubiquitous RFID Tag Data in Wireless LANs
Woo-Yong Choi · Frequenz · 2013
In our previous work, we employed the frame aggregation method and the multipolling method based on the dynamic search algorithm for the AP (Access Point) to efficiently collect the real-time RFID tag data from the RFID readers. However, when a huge number of the RFID readers are associated with the AP, which may be a case in future wireless sensor networks, the dynamic search algorithm is expected not to derive the polling sequence in real-time. In this paper, to deal with this problem we propose the random sequence based multipolling method combined with the frame aggregation method.
