Service-oriented Architectures (SOA) 

service oriented architectures (SOA) L web services (WS) L REST L messaging Service-oriented Architectures 

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

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

Client Application WSN 

Client Application WSN knows: ● HTTP ● user interface design ● high-level languages (java, ruby, python, etc) ● consume REST & real-time APIs 

Client Application WSN needs to know: ● low-level protocols ● convert raw/unfriendly data ● manufacturer differences ● C/C++ knows: ● HTTP ● user interface design ● high-level languages (java, ruby, python, etc) ● consume REST & real-time APIs

Conclusion 

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.
