Although several solutions have been proposed to address the reader collision problem, they are usually based on models that consider only direct collisions among two readers. In real deployments, the additive interference model that captures the accumulation of n concurrent readers' interference is more accurate. Furthermore, even if an additive interference model is considered, it is important to decide how many concurrent readers' interferences have to be considered. The value of n determines a trade-off between the reliability and the efficiency of the RFID system. In this paper, the additive interference model with different values of n is evaluated. The proposed model provides an evaluation tool to select a suitable value of n according to the system requirements and the simulation results have shown the impact of n in a specific deployment.","PeriodicalId":196995,"journal":{"name":"2012 Fourth International EURASIP Workshop on RFID Technology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117179140","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Efficient, need-based control of building lighting through occupancy detection using Passive Infrared (PIR) sensors has become a reliable and well established approach. However, the use of only PIR sensors for occupancy monitoring does not offer much savings and depends upon a building's type and use, and its occupancy levels. Accuracy of occupancy monitoring greatly affects building lighting control strategy and hence, percentage savings. Besides considering lighting control based on occupancy detection using PIR sensors, this paper presents a data fusion approach of passive RFID based occupancy monitoring with PIR. The proposed methodology provides an estimated 13% of electrical energy savings in one open plan office of a University campus building. Practical implementation of RFID gateways provide real-world occupancy profiling data to be fused with PIR sensing towards analysis and improvement of building lighting usage.","PeriodicalId":196995,"journal":{"name":"2012 Fourth International EURASIP Workshop on RFID Technology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125956480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transmitter of the RFID reader is also in operation during receive periods to power the tag and enable backscatter modulation. The state-of-the-art solution employs a leaking carrier canceller, which needs to be adjusted. The proposed fast algorithm provides a starting point for conventional gradient based approaches, which already improves isolation by 7.2 dB at least. It is based on three scalar measurements, and does not demand for special hardware. The algorithm was tested on our RFID test bed and experiments show a significant decrease of steps necessary to reach the final leaking carrier canceller setting.","PeriodicalId":196995,"journal":{"name":"2012 Fourth International EURASIP Workshop on RFID Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125425378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In these environments, the readers within reader-to-reader interference range must transmit at different times, otherwise tags cannot identified. This resource allocation problem is addressed for both static and dynamic Frame Slotted Aloha, which are the most broadly extended mechanism used in UHF RFID systems. The goal is maximizing the expected number of tags successfully identified within the t slots. Results demonstrate that the optimal solution outperforms an assignment proportional to the number of tags in each reader. The results heavily depend on the underlying reading algorithm of the reader.","PeriodicalId":196995,"journal":{"name":"2012 Fourth International EURASIP Workshop on RFID Technology","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128251442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main goal is to determine suitable techniques to manufacture RFID antennas by using different conductive Ag inks, pastes and substrates commonly used in RFID. The physical characterization consisted of measurements of the layer thickness and the RMS roughness of the patterns. DC electrical characterization has been carried out to study different conductive inks and substrates pointing out the lowest sheet resistance and the best printability for each analyzed case. Using the optimal conditions obtained from this work, coil inductors have been fabricated by both techniques in order to validate the present study. Ink-jet printed antennas have been fabricated with Sun Tronic Ag ink on PEI substrates and screen printed antennas have been fabricated on various substrates using screen mesh densities of 90h and 140h. Finally, a semi-passive RFID tag for the HF band providing temperature and humidity sensor capabilities is presented.","PeriodicalId":196995,"journal":{"name":"2012 Fourth International EURASIP Workshop on RFID Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115172301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
