End-to-End Simulation of 5G NR Integrated Access and Backhaul Networks for Remote Maritime Connectivity

Alessandro Traspadini, Andrew Noren, Marco Giordani, Matteo Pagin, Michele Zorzi, Rapha\"el Ihamouine, Rupert Lucas

An ns-3 module now supports full end-to-end simulation of 5G IAB networks where vessels act as both access points and wireless relays for offshore connectivity.

Claims

C1strongest claim

We present an ns-3 module for IAB, featuring a complete end-to-end protocol stack, including the backhaul adaptation protocol (BAP) layer, flexible slot and control configurations, and multiplexing schemes based on both time and frequency division. We test the IAB module via extensive system-level simulations in a custom maritime scenario where vessels, equipped with IAB-nodes, can simultaneously act as access points and relays, forming dynamic multi-hop networks that maintain connectivity via wireless backhaul to shore-based stations.

C2weakest assumption

The custom maritime scenario, vessel movements, and channel conditions used in the simulations accurately reflect real-world offshore propagation and network dynamics (abstract, evaluation section description).

C3one line summary

Develops an ns-3 module for end-to-end 5G NR IAB simulation including BAP layer and evaluates multi-hop topologies under maritime channel conditions.
