Interoperability on low power devices

Model transformation is the process of turning one data format into another according to a specification that contains the operations needed to accomplish it. Therefore it assumes a relevant role on handling interoperability on an “Internet of Things” environment composed by interconnected heterogeneous things with heterogeneous information. However, operate interoperability specifications on this environment is challenging, because model transformation technologies were developed considering an environment composed of devices with processing power and memory, as opposed to the environment exposed. The proposed solution consists in a specific approach, the clear separation of run-time and design time processes and the redefinition of formats used to describe model data and interoperability specification without changing their information. To do so an execution engine architecture is specified, able to execute model transformations according to a lite model data format and an interoperability specification defined as part of the solution.
