Improvement in multiple access channel allocation for sensor node configuration based on RFID communication  RFID  2016/01/12  <p>Wireless sensors are expected to be low cost and to reduce their power consumption so that a large number of sensors can be installed for collecting real-world information. Passive radio-frequency identification (RFID) is proposed to assign communication channels to sensors that only send analog sensing signals for their multiple access control. In this method, the RFID reader-writer assigns channels to all sensors by writing channel numbers to the RFIDs attached to the sensors. We propose a method that more efficiently assigns a multiple access channel to the controlled sensor by using passive RFID. We determine the channel by using the electronic product code (EPC) of the RF tags. This approach results in a large reduction in the number of writes. However, it is shown that there is a tradeoff between the reduction in the number of writes and the total number of channels. In addition, our method has a tradeoff between the reduction in the number of writes and the spectral efficiency.</p>

口頭発表(一般)  A feasibility study of plug-in type RF tag localization system for handheld UHF RFID reader/writers  2015/10  <p>This paper proposes a plug-in type RF tag localization system, using an Angle of Arrival principle, in UHF RFID, particularly targeting handheld reader/writers. Being a plug-in type, the RF tag localization system is receive-only, incurring no radio license requirement, small in size and can be built at low cost. Our fundamental idea is to employ a newly developed short-range mono-pulse method for the RF tag direction detection enabled with affordable software defined radio device and an analog front end. In this paper, we report an experimental evaluation with a functional prototype primarily on the detecting accuracy. It is shown that we can achieve about 3 degree accuracy for RF tags at 7.3 m distance from a 4 W EIRP reader/writer. Because the measurement in the direction of boresight is more stable than the other directions, the direction accuracy can be improved when we feed back the direction detection to the orientation of handheld reader/writer. We also confirm this feature experimentally.</p> 
口頭発表(一般)  Boxcan  APCC  2015/10  <p>This paper introduces «Boxcan», an information retrieval platform for aggregated objects in ID-based object management system based on GS1 EPCglobal architecture framework. Boxcan platform receives an EPC of a container, then provides a tree structure of current parent-child relationship between the EPCs of the container and its inner objects. This paper proposes the system design of Boxcan platform and its applications. The proposed system design is evaluated with a field test of a practical object management system including Boxcan platform. A technical challenge to realize this function of Boxcan platform, fast retrieval of current parent-child relationship of EPCs from EPCIS, is also discussed in this paper. The effectiveness of the caching mechanism of EPC's current parent-child tree, which is a solution to this technical problem, is also evaluated by an experiment in a comparison with direct querying to EPCIS.</p>
