Multi-Connectivity / Handover

The Dual Connectivity framework extends the NYU ns-3 module by adding the capability of simulating a UE multi-connected to an LTE eNB and to multiple mmWave eNBs. This framework can be used to simulate either throughput-oriented (i.e., both the LTE and the mmWave link are used at the same time to increase throughput) or robustness-oriented setups (i.e., LTE is used as a backup in case the mmWave link is in outage). This tool provides complete core network and radio access network infrastructures, and, thanks to the flexibility of ns-3 and to the level of detail of the mmWave channel models, it is a valuable tool to study the multi-RAT scenarios which will be part of 5G cellular networks.
