Mobility Management for the Low‐Altitude Economy: Latency‐Aware Handover Design

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper develops a latency‐aware mobility‐management framework for aerial vehicles operating in hybrid terrestrial non‐terrestrial networks. We formulate a MILP for optimal AV AP association and propose a greedy handover policy using predicted coverage, rate and handover latency.

Safety Assessment of Critical Aircraft Systems Under Multisource Uncertainty Based on Evidence Network

International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
As civil aircraft components become more autonomous in China, airworthiness certification is facing the problem of insufficient failure data, leading to challenges in terms of uncertainty. Traditional probabilistic models struggle to effectively integrate multisource uncertainties, limiting their application in data‐scarce scenarios.
