Abstract:
In passive Radio Frequency Identification (RFID)
systems, tag collisions are more frequent due to lack of
processing elements. Dynamic frame slotted ALOHA algorithms
(DFSA) are popularly being used in passive RFID systems for
collision avoidance. In DFSA based algorithms, selection of frame
size has become a major research problem. Further nonoptimized
frame size selection by reader may lead to energy
consumption. In this paper a framework for optimum frame size
evaluation has been proposed. This framework firstly achieves a
condition for optimum frame size evaluation, and utilizes this
value in new proposed DFSA algorithm. Proposed framework
achieves a throughput of more than 35% along with lowest
possible energy consumption by reader.
