Abstract
This survey explores the integration of MoE and GAI to enable Artificial General Intelligence in the Internet of Vehicles (IoV). The key highlights are: Multimodal GAI can enhance various applications in IoV, including resource allocation and vehicular network security. GAI approaches like GANs, VAEs, and Transformers can be leveraged for adaptive resource allocation, spectrum management, and anomaly detection in vehicular networks. The Mixture of Experts (MoE) architecture can enable the distributed and collaborative execution of AI models in IoV without performance degradation. MoE divides the parameters of the whole model into multiple expert models, allowing computing nodes in IoV to serve as carriers for one or more expert models. The integration of MoE and GAI can enable advanced capabilities in IoV, such as distributed perception and monitoring, cooperative decision-making and planning, and generative modeling and simulation. This convergence can not only augment the capabilities of IoV systems but also pave the way for innovative applications in intelligent transportation and other vertical fields. Several potential research directions are identified, including privacy-preserving collaborative inference, balancing computational efficiency with privacy, and efficient execution of AI-based generative methods to spark Artificial General Intelligence in IoV.

Deeper Inquiries

How can the integration of MoE and GAI be leveraged to enhance the resilience and adaptability of IoV systems in the face of dynamic network conditions and unexpected events?

The integration of Mixture of Experts (MoE) and Generative AI (GAI) can significantly enhance the resilience and adaptability of Internet of Vehicles (IoV) systems in dynamic network conditions and unexpected events. By combining the specialized capabilities of different expert models within the MoE architecture, IoV systems can effectively handle varying scenarios and challenges. Here are some ways this integration can be leveraged: Distributed and Collaborative Decision-Making: MoE allows for the distributed execution of AI models across connected vehicles and roadside units, enabling collaborative decision-making. In dynamic network conditions, this distributed approach ensures that decision-making processes are decentralized, reducing the impact of failures in individual nodes and enhancing system resilience. Adaptive Resource Allocation: GAI models within the MoE framework can dynamically allocate resources based on real-time data and changing network conditions. This adaptability ensures that IoV systems can efficiently utilize resources such as bandwidth, computing power, and energy, even in unpredictable environments. Fault Tolerance and Redundancy: The diverse expertise of multiple expert models in the MoE architecture provides built-in fault tolerance and redundancy. If one expert model fails or provides inaccurate predictions due to unexpected events, other experts can compensate, maintaining system functionality and reliability. Real-Time Anomaly Detection: GAI models can be trained within the MoE framework to detect anomalies and unusual patterns in data streams. This capability is crucial for identifying and responding to unexpected events or malicious activities in the IoV environment, enhancing system security and resilience. Continuous Learning and Adaptation: The integration of MoE and GAI enables IoV systems to continuously learn from new data and adapt to changing conditions. This continuous learning loop ensures that the system can evolve and improve its performance over time, even in the face of dynamic network challenges. Overall, the integration of MoE and GAI in IoV systems provides a robust framework for enhancing resilience, adaptability, and responsiveness to dynamic network conditions and unexpected events.

What are the potential ethical and privacy implications of deploying highly capable MoE-GAI systems in IoV, and how can these concerns be addressed?

The deployment of highly capable MoE-GAI systems in Internet of Vehicles (IoV) raises several ethical and privacy implications that need to be carefully considered and addressed. Some of the key concerns include: Data Privacy: MoE-GAI systems in IoV rely on vast amounts of data collected from vehicles and infrastructure. Ensuring the privacy and security of this data is crucial to prevent unauthorized access, data breaches, and misuse of sensitive information. Implementing robust data encryption, access controls, and anonymization techniques can help protect user privacy. Algorithmic Bias: GAI models within the MoE architecture may exhibit biases based on the data they are trained on, potentially leading to discriminatory outcomes. It is essential to regularly audit and monitor these models to detect and mitigate bias, ensuring fair and equitable decision-making in IoV systems. Transparency and Accountability: Highly complex MoE-GAI systems can be opaque in their decision-making processes, making it challenging to understand how and why certain decisions are made. Promoting transparency through explainable AI techniques and establishing mechanisms for accountability can help build trust and ensure responsible use of AI in IoV. Safety and Reliability: The deployment of MoE-GAI systems in IoV introduces new safety considerations, as these systems play a critical role in autonomous driving and traffic management. Ensuring the reliability and robustness of AI algorithms, conducting thorough testing and validation, and implementing fail-safe mechanisms are essential to prevent accidents and ensure public safety. To address these concerns, stakeholders in the IoV ecosystem, including policymakers, industry players, researchers, and users, must collaborate to establish clear guidelines, regulations, and ethical frameworks for the development and deployment of MoE-GAI systems. Emphasizing principles such as privacy by design, fairness, accountability, and transparency can help mitigate ethical and privacy risks associated with advanced AI technologies in IoV.
