Abstract-- This paper evaluates a new RFID reservation MAC
protocol that utilizes tree based collision avoidance. Performance
evaluation is conducted for tag read latency and read efficiency
as a function of link parameters defined in ISO/IEC 18000-6
Type C standard.
Index Terms-- Anti-collision scheme, ISO 18000-6 Type C, tree
splitting algorithm, thoughput, mean read latency.
RADIO Frequency Identification (RFID) is increasingly
the technology of choice for automated object iden-
tification. The random multiple access protocols in RFID
can be largely classified into two categories: tree based and
framed Aloha based collision arbitrations. The International
Organization for Standard/the International Electrotechnical
Commission (ISO/IEC) 18000-6 Type C (ISOC) standard
uses framed Aloha based reservation MAC for the uplink(UL).
A 16-bit tag identifier called random number 16(RN16) is
