Network Availability Enhancement in Low-Altitude HetNets: A Cross-Layer Design Perspective
Teng Wu, Jiandong Li, Junyu Liu +4
This paper proposes a computing-communication resource interchange method to enhance network availability (NA) in low-altitude heterogeneous networks (LA-HetNets). In these network…
Capacity Scalability of LEO Constellations With Dynamic Link Failures
Wei Li, Min Sheng
Dynamic link failures disrupt the connectivity and geometric symmetry of the constellation structure, thereby increasing protocol overhead and degrading the effective capacity for…
On Capacity and Delay of Wireless Networks with Node Failures
Wei Li, Min Sheng, Junyu Liu +1
One key challenge in designing resilient large-scale wireless ad hoc networks is to understand how random node failures affect fundamental network performance. In this work, we sho…
Dynamic Trajectory Optimization and Power Control for Hierarchical UAV Swarms in 6G Aerial Access Network
Ziye Jia, Jia He, Lijun He +4
Unmanned aerial vehicles (UAVs) can serve as aerial base stations (BSs) to extend the ubiquitous connectivity for ground users (GUs) in the sixth-generation (6G) era. However, it i…
