Abstract

The medium access control (MAC) protocol plays an important role in vehicular ad-hoc networks (VANETs) to provide efficient broadcast service for safety applications. However, the highly dynamic nature of VANETs, such as high mobility and fast topology change, degrades the performance of existing MAC protocols. In this letter, we propose a novel adaptive Time Division Multiple Access-based MAC (VAT-MAC) protocol for VANETs. VAT-MAC accurately and adaptively optimizes each time frame length by estimating and predicting the number of vehicles within the coverage of a roadside unit. It has been proven by mathematical analysis and simulation experiment that VAT-MAC can significantly improve system scalability and throughput.
