Use of Data Compression Techniques for optimizing queries in an RFID Network
This Research investigates the effectiveness of Radio Frequency Identification (RFID) technology in navigating through a network of RFID tags which helps to direct a given person to a desired destination. Due to storage capacity constraints, it is not feasible to store exact information in the form of a map on every tag in the network. As such, each tag contains only a partial map which contains the greatest level of detail on the locations of its immediate neighbors and a lower level of detail on locations of tags that are outside of its neighborhood. This storage scheme enables a person equipped with an RFID reader to decide which neighboring tag should be chosen next on the path towards the eventual destination.
The research applies different compression schemes based on the Haar Wavelet techniques and investigates the effect of these on the length of the path to the desired destination.
