The current ubiquitous presence of RFID tech nology opens up possibilities for new applications. The RFID enabled indoor pervasive environment is the area of interest for our study. We explore the system requirements for an RFID enabled pervasive system and develop a middle ware called GuardianAngel to support a monitoring and guidance system for use in an assisted living environment. This paper describes a prototype of such a system, using real RFID devices in a proof of-concept to evaluate feasibility and emulated RFID devices to evaluate scalability. Our study illustrates the feasibility of such a system, demonstrating greater than 99% accuracy in situ with a confined testbed, and with above 93% accuracy estimated when emulated in a larger environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
