First, what I'm trying to achieve is to implement a gis-based platform in the context of a smartcity. So basically I'll need many layers, some are static like gaz,water circuits, hospitals ...., some are crowd-sourcing based (citizen's reports). The third type of layers I need is sensor-based.
Now for the last layer my problem is that I don't have actual sensors at hand. So what I'm looking for is : is there a sensor emulator, or a sensor data generator of some kind that could feed me random/fake data (temperature,CO2 pourcentage ...) ?
I'm using geoserver as my back-end and I plan to communicate with it using the WFS protocol using openlayers/leaflet as a client. And I can imagine the existance of a program that periodically sends data to geoserveur (via WFT-T maybe, or direct access to the PostGIS database). Which would simulate the actions of a sensor. I read about a protocol called SOS, I don't know if I need it in my case.
Notes : - This is my Master's final project and I have about 2.5 months left - My tool choice is not final (In case another backend/frontend would help me better) - For now I'm looking for sensors in fixed locations, which will be displayed as points or markers on the map.
So to sum up, I'm seeking guidance on how to simulate a sensor and feed the results to a backend GIS server. Any advice is welcome
