The wide adoption of Radio Frequency Identification (RFID) for applications requiring a large number of tags and readers makes critical the reader-to-reader collision problem. Various anticollision protocols have been proposed, but the majority require considerable additional resources and costs. Distributed Color System (DCS) is a state-of-the-art protocol based on time division, without notew...

The main objective of Radio Frequency Identification systems is to provide fast identification for tagged objects. However, there is always a chance of collision, when tags transmit their data to the reader simultaneously. Collision is a time-consuming event that reduces the performance of RFID systems. Consequently, several anti-collision algorithms have been proposed in the literature. Dynami...

Maximizing the Radio Frequency Identification (RFID) performance is one of the main challenges in application domains, such as logistics and supply chain management, where the undesired effect of Tag collisions can significantly degrade the speed of the inventory process. The dominating UHF EPC Class-1 Generation2 (EPC Gen2) protocol only specifies collision avoidance algorithms but makes no pr...

In this paper, a simple frame size adjustment of dynamic framed slotted Aloha for tag identification in RFID networks is proposed. In dynamic framed slotted Aloha, the reader is required to announce the frame size for every frame. To achieve maximum system efficiency, it is essential to set the frame size according to the number unidentified tags appropriately. The proposed approach utilizes th...

Dynamic frame slotted ALOHA (DFSA) has been widely adopted to reduce tag collisions in Ultra High Frequency (UHF) radio frequency identification (RFID) system. In the existing DFSA algorithms, the reader needs to accurately estimate tag backlog and set a new frame length which is equal to the backlog to close to the theoretical maximum throughput 36.8% of the framed ALOHA. To overcome throughpu...

RFID, Radio Frequency Identification, technology is a contactless automatic identification technology about which a lot of researches and developments are recently progressing. For this RFID technology to be widely spread, the problem of multiple tag identification, which a reader identifies a multiple number of tags in a very short time, has to be solved. So far, several anti-collision algorit...

One of the challenged technical issue faced in inventory tracking applications with Radio frequency identification(RFID) implementation environment, is the collisions due to responses from multiple tags on the shared channel between reader and the tags, which consumes further the energy as well as the delay in tag identification process. To avoid collisions by some anticollision algorithm means...

This paper investigates the energy efficiency of RFID anti-collision protocols and their suitability for use in RFID-enhanced wireless sensor networks (WSNs). We present a detailed analytical methodology and an in-depth qualitative and quantitative energy consumption analysis of Pure and Slotted Aloha anti-collision protocols and their variants. We find that Slotted Aloha variants that employ m...

In this paper, bin-slotted hybrid search algorithm (BHS) combined slotted ALOHA procedure with bin-tree procedure is proposed and analyzed. Also, the performance of proposed anti-collision algorithm is evaluated as comparing the BHS algorithm with a standard bin-slotted algorithm (BSA) through the simulation. The performance of the proposed BHS algorithm is improved by dynamically identifying t...
