An Improved Scheme for Vehicular Platooning using Adaptive Acknowledgement Timeout method

Abstract

Platooning provides the potential for substantial benefits in terms of safety, energy conservation and cost reduction. Early analysis has already demonstrated that 65 percent of existing long-haul freight miles could feasibly form platoons, lowering the usage of cumulative vehicle fuel by 4 percent. The emergence of newer communication technologies like the vehicle-to-vehicle networking in the short-range paradigm and device to device communication in 5G paradigm can be used to setup virtual links among multiple vehicles like trucks to form platoons. The vehicular networks are prone to varying channel conditions due to high mobility of nodes. The present work addresses the issue of forming platoons using an adaptive acknowledgement scheme to offer better channel usage and less packet loss. It outperforms existing schemes that uses a static model for message exchange to form vehicular platoons.
