Apresentamos uma nova arquitetura de middleware RFID, Otedama, que faz uso de uma propriedade única da informação RFID para melhorar o desempenho. As etiquetas RFID estão vinculadas aos itens. Novas informações relacionadas a uma etiqueta RFID são geradas no local onde a identificação existe, e a entidade mais interessada na história e no próprio item está próxima da etiqueta RFID. Para explorar esta propriedade, propomos um esquema que agrupa informações relacionadas a um ID específico em um objeto e move esse pacote para um servidor próximo à medida que a etiqueta RFID se move de um lugar para outro. Ao utilizar este esquema, as informações estão sempre acessíveis através de consulta em um sistema próximo à localização física da tag, proporcionando melhor desempenho de consulta. Além disso, o volume de registros que devem ser mantidos por um gerenciador de repositório é reduzido, porque a realocação migra naturalmente os dados à medida que os objetos físicos se movem. Mostramos a eficácia desta arquitetura analisando dados de um grande varejista, descobrindo que o desempenho da recuperação de informações será seis vezes melhor e que o custo da pesquisa será possivelmente várias vezes mais barato.

Abstract: We present a novel RFID middleware architecture, Otedama, which makes use of a unique property of RFID information to improve performance. RFID tags are bound to items. New information related to an RFID tag is generated at the site where the ID exists, and the entity most interested in the history and the item itself is in close proximity to the RFID tag. To exploit this property, we propose a scheme which bundles information related to a specific ID into one object and moves that bundle to a nearby server as the RFID tag moves from place to place. By using this scheme, information is always accessible by querying a system near the physical location of the tag, providing better query performance. Additionally, the volume of records that must be kept by a repository manager is reduced, because the relocation naturally migrates data away as physical objects move. We show the effectiveness of this architecture by analyzing data from a major retailer, finding that information retrieval performance will be six times better, and the cost of search is possibly several times cheaper.
