This paper presents an enhanced Vehicle-to-Everything (V2X) communication system featuring adaptive Medium Access Control (MAC) using game theory. Our approach integrates dynamic transmission power control, dynamic beacon rates, contention window adaptation, and implicit acknowledgment mechanisms within a Manhattan-like grid-based mobility scenario. Simulations are conducted in a circular coverage area, incorporating refined signal propagation models and probabilistic vehicle mobility with boundary reflection. The results demonstrate effective beacon delivery with average delays under 0.35 s and packet loss rates less than 1% in high-density conditions specifically, with up to 80 vehicles operating within a 250 m radius. Key innovations include game theory-based environment-aware transmission parameter adaptation and a scalable design suited for interference-prone V2X deployments.
