IoT application may request a single type of data from a sensor node/system. How can IoT application identify the type of data from many types of data provided by the sensor node/system?
dear
your question depended on your application so if you are programming the sensors and data base you will can do what you want.
you can see this paper
best regards

Dear Saif Aldeen Alkadhim,
Thank you so much for your advice and the recommended paper.
This is application specific. Each data type can be given a unique header/identifier before being transmitted. If you designed the sensor node, you can incorporate the identifier in your code.
Hi Chrispin Alfred Gray, many thanks for your answer.
This means that this kind of data type would be only known by its designed application, isn't it? Can other application get to know and request this type of data type by its identifier?
The short answer is YES, provided you able to figure out the request command from the parent application, then you can programmatically format your request packet/message using the same request command and get a response from the sensor node. Hence the key issue is to find the command used which may / may not be challenging, depending on the application you are looking at.
Hi Chrispin, could you please advice which simulator is feasible for testing new communication protocol between application and IoT devices or sensor nodes?
