5 Unleashing the potential of the Internet of Things

1) Web client requests a WoT service to the WoT-S-MA FE.

2) The WoT-S-MA FE (WoT service management FE) performs user verification with the
WoT-S-PM FE (WoT service policy management FE). The WoT-S-MA FE sends a
message to the WoT-S-PM FE to verify the user. The WoT-S-PM FE checks user
validation and authentication to see whether the user is authorized to access the service. If
the user does not have authorization, the WoT-S-PM FE returns a failure message.

3) When the authentication procedure is finished successfully, the WoT-S-MA FE sends a
message to the WoT-S-DIS FE to discover the service.
4) The WoT-S-DIS FE performs a search procedure with the WoT-S-PRM FE (WoT service
profile management FE). The WoT-S-PRM FE searches for the WoT service and retrieves
information from the WoT-S repository.
5) When the search procedure is finished successfully, the WoT-S-DIS FE returns information
of the WoT service to the WoT-S-MA FE.
6) The WoT-S-MA FE requests executing the WoT service to the WoT-S-EX FE (WoT
service execution FE).

7) The WoT-S-EX FE executes the service, interworking between the WoT-S-EX FE and the
WoT broker function, to use/access things.

8) The web client informs the WoT-S-MA FE to finish the WoT service.
9) The WoT-S-MA FE commands the WoT-S-EX FE to stop executing the WoT service.

10) The WoT-S-EX FE releases resources.
