Optimizing resource allocation in 5G-V2X communication: adaptive strategies for enhanced QoS in intelligent transportation systems

5G vehicle-to-everything (V2X) connectivity plays a fundamental role in enabling advanced vehicular networks within intelligent transportation systems (ITS). However, challenges arising from limited resources, such as unreliable connections between vehicles and the substantial signaling overhead in centralized resource distribution methods, impede the efficiency of V2X communication systems, especially in safety-critical applications. This study critically explores the limitations of centralized resource management in 5G-V2X, focusing on issues of resource scarcity and allocation inefficiencies. In response to these challenges, our approach focuses on optimizing resource utilization within the constraints of limited resources. The article introduces innovative strategies to enhance V2X service satisfaction, emphasizing the efficient allocation of resources for different service classes. Simulations showcase the impact of our tailored approach on resource utilization and satisfaction rates, shedding light on potential improvements in scenarios with constrained resources.
