Resumo: | The computing paradigm called Internet of Things (IoT) will connect billions of devices deployed around the world together in a near future. In the last years, IoT is gaining more attention. This paradigm has become popular by embedding mobile network and processing power into a wide range of physical computing devices used in everyday life of many people. An important element of the IoT is a middleware, which is a system able to abstract the management of physical devices and to provide services based on the information from these devices. The services provided are used by application clients to perform queries and obtain environmental information. In this way, it is already a subject in literature studies that address middleware systems not only interoperability of devices, but also context awareness feature. Context-aware is an important feature of IoT systems. This feature makes easy to discover, understand, and store relevant information related to devices. This information can be used for a refined provision of services based on the environment context and also for decision making. This work aims to present the Context-Aware System (CONASYS), that is a system to provide services of contextualized information about IoT devices in heterogeneous environments. The system is attached to COMPaaS IoT middleware and is able to act accordingly to the environment that it is inserted. We present in details the architecture of CONASYS, the technical issues related to the implementation of the system and perform some tests based in a real-world scenario. We also present some related work. Our objective is to provide a well-defined range of contextualized services that meet the users needs without specific knowledge of the environment, improving users Quality of Experience (QoE). |

Nos ?ltimos anos, a IoT vem ganhando mais aten??o. Esse paradigma tornou-se popular por embarcar redes m?veis e pelo seu poder de processamento em uma vasta gama de dispositivos computadorizados utilizados na vida cotidiana de muitas pessoas. Um elemento importante da IoT ? o middleware, que ? um sistema capaz de abstrair a gest?o de dispositivos e prover servi?os baseados nestes dispositivos. Os servi?os providos s?o usados por aplica??es para obter informa??es do ambiente. Desta forma, existem muitas pesquisas relacionadas com o desenvolvimento de middleware que abordam n?o s? interoperabilidade dos dispositivos, mas tamb?m a caracter?stica de ci?ncia de contexto. Ci?ncia de contexto ? uma caracter?stica importante dos sistemas da IoT. Esta caracter?stica facilita o descobrimento, compreens?o e armazenamento de informa??es relevantes relacionadas aos dispositivos. Estas informa??es podem ser usadas para prover servi?os e tomada de decis?o com base no contexto do ambiente. para provimento de servi?os de informa??o contextulizada sobre dispositivos da IoT em ambientes heterog?neos. O sistema ? acoplado ao middleware COMPaaS e ? capaz de agir conforme o ambiente que est? inserido. A arquitetura do CONASYS ? apresentada em detalhes, assim como os testes realizados. Nosso objetivo ? prover servi?os contextualizados que atendam ?s necessidades dos usu?rios que n?o possuem conhecimento espec?fico do ambiente, melhorando assim a Qualidade da Experi?ncia (QoE).Submitted by Setor de Tratamento da Informa??o - BC/PUCRS (tede2@pucrs.br) on 2016-07-18T20:23:46Z No. of bitstreams: 1 DIS_EVERTON_DE_MATOS_COMPLETO.pdf: 1251543 bytes, checksum: f9774bc8a409974553769c0c5777f444 (MD5)Made available in DSpace on 2016-07-18T20:23:46Z (GMT).
