Redundant Readers Elimination in Dense Radio Frequency Identification Network

Abstract

Radio frequency identification (RFID) is gaining popularity as a tool to monitor and identify tagged objects. The readers were installed at designated location to read the tags in the vicinity. The readings on the object is processed to turns it into useful information for the businesses. However, there are readers that can redundant permanently or only at certain time of period. This is because all the tag that read by the reader has been also read by adjacent reader. The particular reader also does not have any other tags to be read. During this period, the reader can be put into sleep mode to save some energy. For mobile readers, it can be removes from the location and be used in other areas that are much needed. Reducing energy consumption can increase the device lifetimes and promote sustainability such as releasing less emission to the environment. In this paper, we address the problem of identifying this redundant reader using a simple but effective approach. Our approach contributes to energy savings, reduce interference and duplicate readings in the dense RFID reader network. We compare our approach with others and proved that ours is simple but effective and accurate.
