Abstract— In this paper, we introduce a novel mediumaccess control (MAC) protocol for Radio FrequencyIdentification (RFID) systems. This protocol exploits theMarkov Chain Model of Slotted Aloha and there by tries tocome up with a more efficient model so as to significantlyimprove the total read time performance along with thelesser tag collision. The protocol design has been extendedso as to address the problem of cost reduction in RFID .Thisis done by combining the of Markov Chain Slotted Alohamodel for MAC Layer along with Two Time Scale SPSA(Simultaneous Perturbation Stochastic Approximation).Theso designed protocol is programmatically simulated andmathematically the results have been derived to prove itsenhanced performance along with lowered cost involved inobject identification.
