Intelligence MAC Model with Efficient Collaborative Lifetime Improvement Model for Vehicular Ad-Hoc Network

A proposed IMAC-ELI framework addresses the challenges of VANETs by integrating an adaptive MAC protocol and a stochastic route construction algorithm. AdMAC, the Adaptive VANET MAC protocol, dynamically adjusts contention window sizes based on changes in SINR to optimize packet transmission efficiency and reduce collisions. Additionally, a novel traffic assignment optimization module optimizes traffic allocation and constructs stochastic routes for vehicles, enhancing traffic flow and network sustainability. Simulations show that the IMAC-ELI framework significantly improves packet delivery, throughput, delay, and energy efficiency, and reduces routing overhead in VANETs.
