Semantic-Based Bluetooth-RFID Interaction for Advanced Resource Discovery in Pervasive Contexts

Abstract

We propose a novel object discovery framework integrating the application layer of Bluetooth and RFID standards. The approach is motivated and illustrated in an innovative u-commerce setting. Given a request, it allows an advanced discovery process, exploiting semantically annotated descriptions of goods available in the u-marketplace. The RFID data exchange protocol and the Bluetooth Service Discovery Protocol have been modified and enhanced, to enable support for such semantic annotation of products. Modifications to the standards have 1 This is a draft version of the

RFID-based Semantic-enhanced Ubiquitous Decision Support System for Healthcare

“…The device connects to the HIS through semantic-enhanced Bluetooth Service Discovery Protocol, via a hotspot placed in the ward within radio range of beds. Each resource (patient, staff member and drug) is identified by means of an RFID tag with unique EPC code, unique identifier of the reference ontology (OUUID), semantic-based annotation in compressed DIG format and data-oriented resource attributes [6]. The key capabilities of the system (control of drug submission procedures and decision support to the physician for therapy management) will be better explained by means of a small example.…”

“…We set our stage in an e-healthcare context, where RFID tags are dipped into an enhanced Bluetooth framework. In a previous work both the RFID EPCglobal data exchange protocol 1 and the Bluetooth Service Discovery Protocol 2 have been modified to enable support for advanced inference services, while maintaining legacy applications [6]. Here we introduce novel semantic-based value-added services for decision support in healthcare.…”

Mobile Semantic-Based Matchmaking: A Fuzzy DL Approach

“…Regulatory requirements play the role of "request" and the description of a location is a "supply". Annotations related to a given context can be conveyed via the semantic-enhanced versions of most common pervasive computing protocols such as Bluetooth, RFID or even ZigBee [2,19]. Semantic descriptions related to a given environment will be automatically extracted from subjects and/or objects dipped into it and put at disposal for reasoning.…”

“…Note that, even if they have rising performances, battery powered handheld devices are networked by means of wireless low-throughput links and are basically unable to run heavy reasoning algorithms explicitly devised for PCs and servers over the Internet. Knowledge Representation techniques and approaches -which originally enhanced code-based discovery [2]-have been revised to be effectively suitable in volatile ubiquitous computing contexts by-passing the presence of fixed workstations.…”

Semantic-Based RFID Data Management

“…In the research paper [40] we introduced a knowledge-based variant of EPCglobal RFID, whose primary goal was to keep a backward compatibility with the original technology as much as possible. Protocols to read/write tags were preserved, maintaining original code-based access, in order to ensure compatibility and smooth coexistence of new semantic-based object discovery applications and legacy identification and tracking ones.…”
