This module implements a generator of requests to be sent to the LocationService. This application can be instantiated as an "independent MEC app" (see MecHost module), which means it does not need to be instantiated via the MEC orchestrator upon request from a User Equipment. In particular, this module produces bulks of GET requests, as generated by a configurable number of MEC applications running on the MEC host. The result of such requests is to delay the service of real requests (i.e., those originating from complete MEC applications)
