For instance, the present mobile systems suffer spatial problems due to their relatively voluminous antennas. This has prompted bandwidth enhancement and size reduction of Dielectric Resonator Antenna (DRA) of various wireless applications. This paper reviews the latest research pertaining to bandwidth enhancement and size reduction of DRA in the recent year. Subsequently, the pros and cons of different methods to enhance bandwidth such as single stacked DRA structures, special DRA shapes and multi-segment DRA (MSDRA), hybrid DRA have been reviewed extensively. This review also explores the extent of the new techniques used for improving the bandwidth characteristics using DRA and Microstrip line for Next Generation Networks (NGN) applications. Various aspects of bandwidth enhancement techniques, suggestions for merging, modelling and optimization method for designing compact wideband DRAs have been reviewed extensively. Finally, the possible implications are identified for further improvement to overcome shortcomings by employing design modification, alternative modeling, and optimization of design parameters. This will benefit researchers and antenna manufacturers.","PeriodicalId":253369,"journal":{"name":"2013 IEEE International Conference on RFID-Technologies and Applications (RFID-TA)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124451900","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}

On the one hand, the standard describes meticulously the tag responses to reader commands, during the tag inventory process. On the other hand, the standard does not impose many constraints concerning the implementation of the reader side, thus enabling designers and manufacturers alike to implement more or less sophisticated reader behavior. This work demonstrates how this freedom can be used to optimize the identification time in the system for a given tag population, when frame errors on the tag-to-reader channel are present. Some standard compatible retransmission strategies are proposed and evaluated in simulations. Additionally, an extension to the standard protocol, based on type-II hybrid ARQ, is proposed and evaluated. The results of the simulations show, that a suitable implementation of the retransmission strategy directly leads to an improved identification time at a degrading tag-to-reader channel, which in turn means that the operational range of the system can be increased, while the identification time is kept constant.","PeriodicalId":253369,"journal":{"name":"2013 IEEE International Conference on RFID-Technologies and Applications (RFID-TA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125045107","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 protocols must be able to adapt to the unpredictable dynamic topology. This study investigates the conventional DSR and DSDV routing protocol with the aim of improving DSR routing protocol using TTL-based scheme. The preliminary investigation showed that DSDV outperformed DSR most especially when the nodes moved at high speed, which was due to inability of the DSR to repair a broken link locally and lack of any mechanism to control the freshness of routes when there are multiple options. A new mechanism, DSR_TTL was proposed in order to improve the performance of conventional DSR. The analysis was based on the small network size with constant and variable speed. The results of the study indicated that a medium number of TTL revealed a high performance for the metrics used for the study. Therefore, with all default parameters unchanged as in conventional DSR protocol, the new TTL value was set for the proposed protocol. The results have shown that the proposed protocol generally improved the network throughput and reduced the total overhead.","PeriodicalId":253369,"journal":{"name":"2013 IEEE International Conference on RFID-Technologies and Applications (RFID-TA)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127865127","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}

Main idea behind fingerprinting is to build signal strength database of target area prior to location estimation. This process is called calibration. Indoor positioning system accuracy highly depends on calibration (sampling) intensity. This procedure requires huge amount of time and effort, and makes large-scale deployments of indoor positioning systems non-trivial. Newly constructed database may no longer be valid if there are any major changes in the target site. In this research we present a new approach of constructing fingerprint database. We propose a hybrid calibration procedure that combines signal sampling process with path-loss prediction algorithm. Instead of manual signal sampling, proposed method requires several Wi-Fi RFID tags to be installed in a target site. Advantage of such tag is that it can be read directly by commercial Wi-Fi access points from long distance. Several RFID tags mounted in target area will monitor the signal strength levels continuously and send scan data to the server. Whenever there are significant changes in signal levels detected, server will initiate database reconstruction procedure. Compared to existing calibration procedure our method requires only few signal samples from RFID tags to be collected and rest of the database is recovered using path-loss prediction algorithm.","PeriodicalId":253369,"journal":{"name":"2013 IEEE International Conference on RFID-Technologies and Applications (RFID-TA)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127531635","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}
