MAC Protocols for RFID Systems
, 2010 A very common requirement in RFID systems is the reading of co-located tags, that is necessary when multiple tags are found simultaneously in the coverage area of the tag reader. Due to the low latency and low power constraints of these systems, the availability of efficient protocols able to arbitrate collisions and guarantee shared access to the ...
