To support smart vehicular services especially in the future driverless era, the vehicular networks are expected to support high-bandwidth content delivery and reliable accessibility of multifarious applications. However, the limited radio spectrum resources, the inflexibility in accommodating dynamic traffic demands, and the geographically constrained fixed infrastructure deployment of current terrestrial networks pose great challenges in ensuring ubiquitous, flexible, and reliable network connectivity. This book investigates mobile edge content caching and delivery in heterogeneous vehicular networks (HetVNets) to provide better service quality for vehicular users with resource utilization efficiency enhancement. Specifically, this book introduces the background of HetVNets and mobile edge caching, provides a comprehensive overview of mobile edge caching-assisted HetVNet techniques in supporting vehicular content delivery, and proposes/designs mobile edge content caching and delivery schemes in different HetVNet scenarios respectively to enhance vehicular content delivery performance. Afterward, this book outlines open issues and research directions in future mobile edge caching-assisted space-air-ground integrated vehicular networks. The topics addressed in this book are crucial for both the academic community and industry, since mobile edge caching in heterogeneous networks has become an essential building block for the communication systems. The systematic principle of this book provides valuable insights on the efficient exploitation of heterogeneous network resources to fully unleash their differential merits in supporting vehicular applications. In addition, this book considers different HetVNet scenarios from terrestrial HetVNets to air-ground HetVNets and space-air-ground HetVNets, which can provide a general overview for interested readers with a comprehensive understanding of applying mobile edge caching techniques inenhancing vehicular content delivery performance, and offer a systematized view for researchers and practitioners in the field of mobile edge caching to help them design and optimize the desired vehicular content delivery systems.Provides in-depth studies on mobile edge content caching and delivery scheme design for three typical HetVNet scenarios;Comprehensively covers the analysis, design, and optimization of the mobile edge content caching-assisted HetVNets;Systematically addresses vehicle mobility, network service interruptions, and dynamic service request distribution issues in the mobile edge content caching and delivery.

This book introduces state-of-the-art research on Satellite-Terrestrial Vehicular Networks (STVNs). It develops theoretical models for performance analysis, evaluating the joint impact of constellation parameters, satellite mobility and terrestrial deployments. Building upon these foundations, this book explores multi-dimensional resource management across satellite and terrestrial networks. Under the slicing-based two-stage framework, adaptive resource slicing for high-definition map distribution and cooperative resource scheduling for environment sensing are presented. This book also provides valuable theoretical foundations and practical insights for the design and optimization of future STVNs. Satellite-Terrestrial Vehicular Networks STVNs, which integrate low Earth orbit (LEO) satellites to supplement terrestrial vehicular networks and offers a heterogeneous architecture to extend network coverage for connected vehicles (CVs). Leveraging vehicle-to-everything (V2X) communication, STVNs can support multifarious safety- and efficiency-oriented applications to expand situational awareness, reduce response time and smooth traffic flow. To meet stringent requirements for network continuity, low latency, and high service reliability under dynamic environments, this book systematically explores resource management for STVNs. It conducts theoretical models for performance analysis and developing multi-dimensional resource management schemes to enable reliable, low-complexity, and adaptive service provisioning for CVs. This book serves as a useful reference for researchers and engineers in the fields of vehicular networks and integration of satellite-terrestrial networks to help them design and optimize resilient communication networks. Advanced-level students in computer science and electrical engineering will also find this book useful as a study guide.
