A network reference model for B2C RFID applications

RFID has been adopted so far in business fields due to such problems as expensive tag price, privacy issue, no tiny reader, etc. But currently RIFD is being adopted in cell phones so that customer-purposes RFID applications can be provided in the B2C manner. How to establish the service infra is a challenging issue and only the case of KDDI is known to the public. It operates based on the service broker model. But this paper describes the E2E-based communication model. It figures out prospective network entities, network configurations, how to resolve the code resolution from an RFID code to a URI (uniform resource identifier), how to retrieve information contents such as music, video, game, etc. With this result, an alternative network reference model can be suggested to the market and Koreas mobile network operators are adopting this proposed architecture

An integrated mobile RFID service architecture between B2B and B2C networks

This paper proposes mobile RFID service architecture using RFID tags of B2B. To use RFID tags of B2B in mobile RFID service network, two approaches may be available. One is that network entities in mobile RFID service network access to network entities in B2B network and uses contents of B2B for mobile RFID service. The other is that only UII in RFID tag is used in mobile RFID service which does not require access to network entities in B2B. For these purposes this paper proposes mobile RFID service gateway. Also the requirements and the functions of the service gateway are defined.

Towards zero-configuration in device collaboration using device sociality

Collaboration of smart devices often requires troublesome configuration and management, involving human interventions. In order to reduce these burdens, smart devices should be able to configure and manage themselves in device collaboration, self-understanding high-level information such as social relationship between the owners. We propose a concept called, device sociality, which aims automatic configurations in device collaboration via self-constructing social relationships. Device sociality describes social relationships of devices, which can be identified by analyzing machine-level communication data and human social data. We conducted an initial experiment to show that devices can self-identify their social relationship with minimum human intervention. We verified the result with user survey, providing that devices are able to collaborate autonomously with device sociality.

An energy management framework for smart factory based on context-awareness

In this paper, an energy management framework for smart factory is illustrated based on context-awareness. The smart factory is composed of the three layers, and IoT sensors are deployed in the smart factories and used to collect many kinds of data including personnel, equipment, and environment. The first layer, the data collection and control layer, collects and sends environmental and control data to the second layer. And, the second layer, energy management based on context-awareness layer, analyses the data and infers the context from them. Finally, the energy service layer provides energy management services to users through monitoring and controlling the status of energy consumption. Using the proposed scheme, users can monitor their energy consumption, and control their utilities and equipment to avoid energy leakage.

Design and implementation of an energy trading model for smart factories

This paper describes an energy trading model for efficient energy saving and management services. The energy consumers and suppliers in smart factories can trade their energy using the proposed model. First, the market participants register their information and select the roles of the energy suppliers or the consumers. They can change the roles depending on the situation. And the energy suppliers register the energy resources to the market server. And many energy consumers can apply the appropriate tender. When the bidding time ends, the market server calculates and determines the bidding results, and sends them to the bidding participants. According to the results, the consumer who received the winning bidder can use the energy during the appointed time. Using the proposed model, the suppliers and the consumers can easily trade the energy of smart factories, and can save the cost by trading the remained energy with reasonable prices. Also, the nation achieves the overall cost savings for energy by the balance of demand and supply.

Secure RFID personal data management using privacy reference profile

We propose a secure framework for mobile-phone based RFID service using personal privacy policy based access control for personalized ultrahigh frequency (UHF) tags employing the Electronic Product Code (EPC). The framework, called mobile RPS, has dynamic capabilities that extend upon extent trust-building service mechanisms for RFID systems. This new technology aims to provide absolute confidentiality with only basic tags.

Modeling of manufacturing software catalogue for interoperability in manufacturing systems

This paper proposes a way to describe the capability of software of manufacturing systems that can be mapped to the functional requirements of target manufacturing application for interoperability. For this objective, this paper specifies how to develop and manage software catalogue in terms of capability properties, and defines mapping rules from capability profiles to software catalogue.

Relation management for machine socialization

This paper presents relation management for machine socialization. Machine socialization is making thing or machines to talk to and say what they do or need to each other follow each other, discuss with each other and collaborate with each other. Relation is an association between or among object capability within machine enabling to share or provide capability to achieve the task in collaboration. Relation includes scheduling of process between or among machines during performing the task This paper also presents relation models for machine socialization.
