Trustworthiness in the Air: Age of Incorrect Information Oriented 6G Low-Altitude Networks

In the era of 6G networks, the demand for robust and trustworthy communication systems has become more critical than ever, particularly in MIMO-enabled flying ad hoc networks (FANETs), also known as low-altitude networks. These networks combine the flexibility of aerial platforms with the high-capacity advantages of MIMO technology to support critical applications such as disaster recovery and urban management. However, ensuring trustworthiness, comprising reliability, security, privacy, and resilience, remains a significant challenge, especially under dynamic and adverse conditions. Current evaluation metrics fail to comprehensively assess these aspects, as they focus on isolated parameters such as latency or packet error rate. To address this gap, this study introduces a novel trustworthiness evaluation framework based on the age of incorrect information (AoII), extending traditional metrics by capturing the impact of erroneous information over time. The proposed multi-user MIMO FANET architecture, leveraging enhanced carrier sense multiple access (CSMA) mechanisms, achieves higher reliability and efficiency. Simulation results validate the feasibility of our framework, offering insights into the design of future 6G FANETs.
