Towards a fully connected world, wireless networks are evolving to interconnect everything, including people, vehicles, wearables, and robot agents. However, these network nodes are rarely stationary, leading to high-mobility wireless networks with constantly shifting network topologies. Due to these node movements, high-mobility networks are facing significant resilience challenges, like frequent connection disruptions and considerable packet delivery delays. To address these challenges, this proposal aims to develop a framework for resilient networking on moving nodes and devise efficient systematic solutions for enhancing the network resilience against mobility dynamics. The whole proposal is structured into three work packages (WPs), strengthening the resilience of high-mobility networks respectively from three key perspectives. First, in WP [A], we focus on enhancing connectivity resilience in high-mobility networks. Specifically, we will propose an efficient mobility-tolerant station deployment strategy to maximize connectivity coverage and minimize out-of-service probability for these high-mobility network nodes. An effective mobility-adaptive traffic load balancing solution will be further proposed to ensure resilient connection scheduling and prevent station overloads. Next, WP [B] concentrates on the service resilience in high-mobility networks. We will develop efficient approaches for mobility-aware computation offloading and content caching, enabling resilient service delivery over the established resilient connections in WP [A]. Together, WP [A] and WP [B] will ensure successful service completion despite user mobility during the service process. Finally, WP [C] addresses network resilience in face of irresistible station shutdowns, emphasizing the network survivability. Specifically, in case of station failures, the network will transit to a survival operation mode, to sustain communication service for moving nodes until station restoration. We will leverage the potential of floating content (FC) communication and deploy movable communication assistant devices (MCAD) to further accelerate FC communication. High node mobility will be explored to assist the message spread toward inaccessible service regions. Efficient MCAD trajectory designs and real-time MCAD control will be developed in this WP for rapid service delivery to these regions. The resilient scheduling of connectivity and service in WP [A]-[B], combined with the backup solution in WP [C] for survivability, constitutes the overall resilient networking framework for high-mobility nodes. The proposed solutions across all WPs will be evaluated in simulated high-mobility networks under different network topology and various mobility patterns. Via comparisons with diverse benchmark solutions, the effectiveness of our proposed designs in enhancing network resilience will be demonstrated.
