Summary

This thesis explores the improvement of caching mechanisms within Internet of Things (IoT) and Internet of Vehicles (IoV) networks in order to mitigate backhaul network congestion, extend the lifetime of IoT nodes and improve overall network quality of service. It begins by introducing a clustering method within IoT infrastructures, using multi-criteria decision making techniques such as TOPSIS and AHP to optimise cache placement among nodes and leveraging Software Defined Networking (SDN) for efficient routing. The work then looks at IoV networks, differentiating between security and entertainment content caching strategies. Security content caching is localised and dynamic, based on incident severity and data freshness, while entertainment content caching employs federated learning to predict content popularity without compromising user privacy. The final aspect of the research addresses the challenges of network coverage and load distribution through the deployment of Unmanned Aerial Vehicles (UAVs). An optimisation model for UAV placement is developed, taking into account energy constraints, user satisfaction, required data rates and resource efficiency, with the application of reinforcement learning to solve this complex problem. Together, these strategies form a coherent approach to reducing latency and improving Quality of Service in vehicular networks.
