Abstract |
Automatic identification systems (barcode, smartcard, RFID…) are a common and a useful tools in manufacturing, supply chain management, payment system…Due to the low cost and its flexibility, radio frequency identification technology (RFID) has emerged a lot of applications (access control, antitheft car systems…) This technology aims to uniquely identify physical object attached to a so called tag or transponder. When the reader attempts to identify more than one transponder, it may face up a simultaneous interfering transmission from transponders which may causes a collision as tags share the same communication channel. For this generic multi access communication problem, several algorithms have been proposed to identify tags. These protocols are classified into deterministic approach and probabilistic collision resolution. The main focus of this work is to analyze the performance of aloha protocol in the case of RFID communication system. |
