Proposing a secure and efficient group handover protocol for 5G non-terrestrial networks to mitigate signaling storms and enhance security.
Resumo
The content discusses the challenges faced by 5G handover protocols in non-terrestrial networks due to high satellite mobility. It introduces a novel group handover protocol to address these challenges, focusing on efficiency and security. The paper evaluates the proposed protocol through simulations, comparing it with baseline 5G handover schemes. Key highlights include:
- Challenges of handovers in non-terrestrial networks.
- Proposed secure and efficient group handover protocol.
- Evaluation through discrete-event simulations.
- Comparison with baseline 5G handover scheme.
- Analysis of security aspects and efficiency trade-offs.
Estatísticas
"In our solution, AMF is responsible for forming UE groups in its tracking area."
"The UE density is about 36 UEs/km2, requiring the satellite to hand over 2.6 × 104 UEs/second."
"In GHO, the total messages are smaller than in HO, which reduces the burden on the satellite."
