Storing information from an IoT in the cloud

Mission:

To create a relay to collect information from an IoT and use a webservice to save information in the cloud.

Background:

My own defined webservices see http://anbo-easj.dk/prog3/wcf/exerciseWCF_whatIsPossible.html

UDP programming see http://anbo-easj.dk/tek3/socket/udpBroadcast.html

Exercise

A) Create a webservice to store and fetch data

Design and implement a webservice having following methods:

• SaveInformation (String meassuredData)
• List<String> GetInformationFromPeriod(DateTime from, DateTime to)

The data are save in some store (your choice - e.g. see http://pele-easj.dk/2015e-prog/exercises/AzureStorages.html)

B) Create a Relay Station

Design and implement a new project/program that receives data (UDP packets) from the raspebarryPi on port 7000 and send them forward to the webservice
which adds a timestamp and store the information in some storage.

C) Create Web Service Comsumer

Design and implement a new project/program that can receive data from a specified period, and display these to the screen (Console or Gui at choice).

Additional exercises

• Change the web service interface to send parsed data i.e. SaveInformation(byte temp, byte light, byte potentiometer, String dateTimeOfLastMovement)
• Buffering received data and only save informationen each minute (spare network traffic)
• Only sent information if it had changed from last UdpPacket
• More advanced get Methods e.g. GetInformation returns a list of struct having the data {temp,light,potentiometer,lastMovement} or
  GetInformationWithMinTemp(byte minTemp) ...

Extra (very simple 'sensor'):

Design and implement a new UDP sender (could still be to port 7000 or use another port)

This sender should send out from time to time a current timestamp.

Refactor your webservice to handle these new events.
