Abstract

Radio Frequency Identification (RFID) technologies are applied in many fields for a variety of applications today. Recently, new solutions are proposed to deploy RF tags on the ground instead of attaching them to objects for RFID-based monitoring and localization. However, the optimal tag deployment strategy is yet to be addressed. In this paper, we identify the optimal deployment patterns that guarantee k-covering (i.e., at least k RFID tags are accessible anywhere in the deployment region), where k=
