Question:
Best FIWare architecture?

Description:
We are developing a FiWare city sensor network that:

Inside the sensor processes data in real time and publishes their average every N minutes to our server;
some server side math to do with those reported averages, which will generate new fields or averages of already reported fields (e.g. average by day);
In the end, there will be a Wirecloud component showing a map with the location of every sensor and a plot showing the several fields acquired, by sensor.

Aditionally, sensors can raise alarms and every server and sensor access must be secure and server database scalability it's a future concern. At the moment we have this architecture (OCB stands for Orion Context Broker):

Where the "Webservice" and "Processing" components are house made, but after reading a little bit more about FIWare components (particulary the IOT stack) I've realised that there are more components that we might integrate in here.

What are you using for a solution like this? It looks fairly generic (secure attributes publish, storage, post-processing and value plot).
