IoT Data Sources
Published in Chandrasekar Vuppalapati, Building Enterprise IoT Applications, 2019
The iOS architecture following Model-View-Controller design pattern (see Figure 30) with clear separation of roles of Controller (handles events), Model (lifecycle of data objects) and View (User Interface elements). The Application Delegate Object creates the Window Object. Under the Window Object, View and View Controller Objects are created. The data is stored in the Data Object that connects to Application and View objects in order to send or receive the data [15].

The serial port is initialised at 115,200 baud. A serial data receive event and its delegate function are defined. On serial data receive event the function verifies if the data is from the AP & confirms by checking its MAC address. On verification, the required data is parsed & forwarded to the GUI layer of the application.
End-user development in industrial contexts: the paper mill case study

In our solution, since it was problematic to perform the experimentation in a real industrial setting, two simulators have been developed to simulate the occurrence of events and actions, respectively. The one dedicated to events simulates situations occurring on production lines (by using it, the user can monitor the state of the production lines and also change relevant parameters associated with its composing equipment, for example, the weight of paper trim losses detected at the end of the production cycle and measured through some weight scales), and also the occurrence of emergency situations (such as the ‘man-down’ alarm, which in real scenarios is typically issued by dedicated devices that detect worker’s falls). The event simulator pretends to be a Context Delegate and it sends the event updates to the Context Server in order to eventually trigger some rules. As for the actions, the corresponding simulator provides a view of the factory, which includes elements, such as coloured semaphores highlighting specific situations on production lines (e.g. a red semaphore indicates a situation that needs further attention). The action simulator acts as an Application and it really subscribes to the Rule Manager in order to receive the actions when a rule has been triggered.
