ISAC based seamless handover solution for SAGIN in high mobility environments.

Area of Science:

• Network Engineering
• Telecommunications
• Aerospace Communications

Background:

• High-mobility environments like aerospace and high-speed transport require robust connectivity.
• Conventional handover procedures in Space-Air-Ground Integrated Networks (SAGIN) suffer from frequent connection loss, high latency, and degraded Quality-of-Service (QoS).

Purpose of the Study:

• To develop a novel, seamless handover procedure for SAGIN tailored to high-mobility environments.
• To leverage Integrated Sensing and Communication (ISAC) for improved handover decision-making and resource allocation.

Main Methods:

• Introduction of a new high-mobility handover procedure for SAGIN utilizing ISAC.
• Integration of real-time environmental perception for enhanced handover decision-making.
• Combination of dynamic priority scheduling and a cross-layer communication protocol for seamless inter-layer mobility.

Main Results:

• MATLAB-based simulations demonstrated significant latency reduction compared to existing methods.
• The proposed method achieved enhanced network throughput with minimal packet loss.
• Effectively balanced spatial, air, and ground network resource allocation.

Conclusions:

• The developed handover procedure is suitable for maintaining QoS in highly dynamic SAGIN environments.
• The approach offers a promising solution for seamless connectivity in aerospace and high-speed terrestrial transportation.
• Opens new research avenues for SAGIN and high-mobility networks.
