10. SOA: REST and RESTful services
    - resource-oriented;
    - request-response;
    - client-server;
    - language-independent.
    → GET /sensors/5 HTTP 1.1
    ← { “id”: 5, “manufacturer”: “SUN” }

11. SOA: Messaging and Publish/Subscribe
    - topic-based;
    - push technology;
    - client-server and
    machine-machine;
    - more coupled.

47. Conclusion
    ● it was possible to consume data from a WSN using existing communication
    interfaces and protocols;
    ● consuming the data from a WSN did not require specific technical knowledge
    about it;
    ● the average delay of a connection between a client application and the
    network was below 400ms, following ITU G.114’s recommendation;
    ● through the Terra Web application it was possible to demonstrate the use of
    real-time and REST APIs working together and meeting different purposes.
