Energy Efficient Adaptive Bit‐Mapping Based Collision‐Free MAC Protocol for VANETs

IET Intelligent Transport Systems, Volume 19, Issue 1, January/December 2025.
In the present work, an energy‐efficient medium access control (MAC) protocol is proposed for the adaptive data traffic condition in VANET. The proposed protocol optimizes communication efficiency and energy conservation through a holistic approach that considers the dynamic nature of both the vehicles' energy resources and their data buffering ...
