dc.description.abstractRadio frequency identification (RFID) is used to identify, track, and manage tagged animate or inanimate objects automatically using wireless communication technology. RFID is similar to existing barcode identification, but it has additional features. RFID has the capability of scanning multiple objects at the same time. This improves productivity by reducing the time taken to identify objects. RFID has the capability to read through opaque material without requiring line of sight, thus saving time in processing that would otherwise require upwardfacing objects. RFID is extremely appropriate for applications that require tags to be read at large distances. RFID readers and tags come in various sizes and forms, thus permitting this type of technology to be used in a broad variety of situations. Some tags are blast-proof, some tags are the size of lunch boxes, and some are smaller than a grain of rice. Also, RFID tags can be reprogrammable, thus reducing cost. As RFID technology continues to grow rapidly, different issues and challenges are presented. A serious concern faced by RFID technology is the collisions that occur during communication. This is considered one of the immense challenges in RFID development because collisions limit system performance significantly. Collisions bring extra delay, a waste of bandwidth, and extra energy consumption to the interrogation process of RFID. Delays that arise due to collisions in RFID systems create significant issues and challenges to applications that require high inventory speed. Therefore, RFID system designers and researchers need to simulate these different environments before deployment to correctly identify various factors, such as the number of RFID readers needed, where to place these readers, etc. The simulator developed in this research is called the RFID Simulator. It was developed completely from scratch to evaluate the performance of Slotted Aloha and EPCglobal Class-1 Generation-2 protocols for RFID systems. The RFID Simulator was designed to replicate a reallife RFID environment. It can be used to imitate hardware and has the capability to calculate the delay to any number of RFID tags, which is not possible with real-life RFID systems. As a result, the performance of RFID systems can be improved significantly. The integrity of the simulator was verified by comparing its results with mathematical analysis and experimental results. The RFID Simulator is a complete, all-in-one package, designed with the ability to be extended to a commercial RFID simulator, which will help immensely in the future development of RFID.en_US
