Name	Type	Description
MecRequestApp	simple module	This module provides an application model to be run at a User Equipment (UE), which generates periodic requests to be sent to a MecResponseApp module hosted on an (edge) host, located next to a base station. For each request, it expects to receive a response from the MecResponseApp. This module records statistics about the Round-trip Time (RTT). Optionally, the effect of migration can be simulated when the User Equipment (UE) performs a handover to a different base station. In this case, the application can be configured to forward new requests to a different (edge) host, namely, the one located next to the new base station.
