Datasets

Dataset used to simulate the behaviours of the entities involved in the use case can be found at /datasets. Datasets related to carparks, vehicles, weather, and places can be found here. These datasets can be simulated using the entitySimulator found in the code OR using the IoT dats simulator (https://github.com/IBA-Group-IT/IoT-data-simulator/tree/master).

Context consumer SLAs are available in contextConsumer.json. All the registered Context Providers are available in contextService.json.

Experimental Setup

The JMeter file (.jmx) used to simulate the context queries can be found at /experiment/test-plan.jmx. Use the requests.csv in /datasets to set the context query load.

NOTICES

The service containers assuming an alreday running container instance of 'mongodb'. Please use the dockerized-solution branch for the solution using Docker containers related to the publication 'Estimating the lifetime of transient context items'.
