MecRequestForegroundApp¶

Package: simu5g.apps.mec.MecApps.MecRequestForegroundApp

simple module MecRequestForegroundApp

Implements a MEC application that issues GET requests to the LocationService every 500ms. This application can be utilized as an “independent MEC app” (see MecHost module), hence it does not require instantiation via the MEC orchestrator upon request from a User Equipment. Essentially, this application provides a quick way to generate configurable load to the Location Service and simulate different (and potentially more realistic) response times from the latter.
