Multi-RAT Wireless Network Simulator

This tool is designed to simulate resource allocations in 4G, 5G and Satellite networks, without entering in the details of the various protocols and of the syncronization mechanisms. Moreover this simulator does not considers actual transmission of the data, but just allocation of uplink/downlink resources.

This simulator is very modular and the internal logic of each component can be changed according to specific needs.

According to the idea of Multi-RAT, in this simulator the User Equipment (UE) is not aware of the type of Access Point (AP) it is connecting to. This implies that the UE makes a request in terms of bitrate to one (or more) AP(s). Each AP, will then compute the actual network resources to be allocated (Resource Blocks for LTE and NR networks, Symbols for Satellite networks) considering the path loss between AP and UE and the inter-AP interference.

This simulator can consider also the movement of UEs, as well as the movement of the APs (with the Drone BaseStation/Relay):

• UEs have fixed speed and there are two possible movements implemented at this time:
  • random movement
  • line movement given a direction, with bumping on the borders of the map
• Drones move with a maximum speed towards a certain point; the speed control is done using the unicycle model (without considering orientation)
