Energy Efficient Approach in RFID Network

Abstract

Abstract. Radio Frequency Identification (RFID) technology is among the key technology of Internet of Things (IOT).It is a sensor device that can monitor, identify, locate and tracking physical objects via its tag. The energy in RFID is commonly being used unwisely because they do repeated readings on the same tag as long it resides in the reader vicinity. Repeated readings are unnecessary because it only generate duplicate data that does not contain new information. The reading process need to be schedule accordingly to minimize the chances of repeated readings to save the energy. This will reduce operational cost and can prolong the tag's battery lifetime that cannot be replaced. In this paper, we propose an approach to minimize energy spent during reading processes. Experiments conducted shows that proposed algorithm contribute towards significant energy savings in RFID compared to other approaches. [5]. It enables process improvement on the area where it turns tedious manual works into simplified automated process. For example, instead of scanning the barcodes manually, RFID can simultaneously read all the objects and return related data to the system in very short time [6]. The growth of RFID deployment has been exponential since its reintroduction in the late 90s. In 2006 the number of tags has been sold is three times bigger than over the previous 60 years [7]. In 2014, the total market value for RFID is $9.2 billion and is expected to reach $30.24 billion in 2024 [8]. IntroductionBased on this market pattern and trajectory, it is expected that RFID will becoming the most common pervasive devices in our life. As the most widely used technology, we need an energysavings mechanism to cut the system operational cost. Minimizing the usage also can prolong the devices lifetime which help businesses obtain longer return-on-investment period. In certain circumstances, such as deployment at a natural disaster place [9], energy savings conscience is very important as the energy resource were limited and hard to be renew. For example the use of active tag to detect trapped coal miners in the tunnel [10]. The evacuation need to be done quickly before the battery on the tag dried out.In this paper we present how energy savings is achieved through efficient reader scheduling mechanism. The readers are schedule in a way that no adjacent reader will do reading at the same time. Based on this the risk of signal collision is reduce to zero and the need to repeat readings because of the collision can be avoided. The tag in the overlapped vicinity also can be read by only one reader

“…The RFID system is used in energy companies and serves, inter alia, for marking network assets and allows one to track the use of materials in an energy company, e.g., poles and transformers or other components of network infrastructure and energy devices. In the case of poles and transformers, passive UHF RFID tags are attached to all poles and transformers, letting one know where the materials are [52]. The company can control whether the materials are still in stock, have already been installed, or have been returned to the warehouse because they were not used for installation.…”
