Analysis of DCNS anti-collision protocol with contiguous channel allocation

In radio frequency identification (RFID), reader-to-reader collision problem is contemporary topic of research. Among state-of-art protocols, it is investigated that although distributed color noncooperative selection (DCNS) protocol provides high throughput solution for RFID networks without any additional hardware requirements but it does not provide a complete collision free network. In this work, two contributions are presented: finding the flaws in DCNS protocol and proposed improved DCNS protocol with contiguous channel allocation for collision free network. Simulations have been conducted in order to analyze the proposed modifications. Results shows that the improved DCNS protocol provides better system throughput compared to state-of-art protocols.
