资源描述This paper presents a lowcost indoor location identification and material tracking methodology for construction
projects using Ultra High Frequency (UHF) passive Radio Frequency Identification (RFID) technology. Onsite
location aware information is an emerging area that focuses on automating delivery of spatial information
pertinent to location of materials, workforce, and equipment. This spatial information can be used to derive
knowledge about construction project status. A two-step algorithm is presented to automate the process of
location estimation and material tracking in near-real-time. In this methodology, a number of passive RFID
tags are distributed onsite where work is progressing, and a mobile RFID reader is carried by a worker onsite.
Each passive RFID tag is deployed as a reference point with a known location (landmark) within a predefined
zone. Reference tags of known locations are used to d
