Vehicle-to-Vehicle (V2V) communication is a key technology enabling the realization of efficient and safe transportation systems (Kokatnur et al. in V2V Communication Using DSRC. Springer, Singapore, 2024). In V2V communication, the efficient allocation of resources is crucial to ensure reliable and timely data exchange among vehicles. This paper investigates the dynamic resource allocation strategy focusing on Subchannel Interleaving (SCI) Block Error Rate (BLER) in V2V communication systems. We propose an approach that adapts resource allocation dynamically based on real-time SCI BLER measurements. The objective is to optimize resource utilization while maintaining satisfactory communication quality. We present a detailed analysis of the proposed dynamic resource allocation scheme, including performance evaluation through simulations. Our results demonstrate the effectiveness of the proposed approach in improving system reliability compared to static resource allocation strategies. The findings of this study provide valuable insights for designing efficient V2V communication systems that can better accommodate dynamic and varying communication conditions on road.
