With the rise of the Internet of Things (IoT) billion devices will be connected to the internet of the future producing, consuming and processing data and communicating with each other. Discover and select eciently the devices best suited to a particular need, appear as relevant issues to be investigated in the IoT. In view of this problem, the present work proposes: (i) using and monitoring quality metrics in the description of the data producers, (ii) the propose of a ranking of data producers technique that makes use of quality attributes, (iii) the suggestion of dynamic queue results by the search engine and (iv) the use of REST style for providing data producers as resource. Finally, it was considered a use case scenario of the mobile application Bike Cidadao in order to evaluate the performance of the proposed contributions. The evaluation noted, above all, the response time required to perform queries to the catalog using, or not, the concept of dynamic queue results in different situations, varying the amount of data available to consumers and producers. |
