Beaconing and transmission range adaptation approaches in vehicular ad hoc networks: Trends & research challenges

Exchanging information efficiently between vehicles or between vehicles to infrastructure is a keystone to successful deployment of vehicular ad-hoc networks (VANETs). This information is required by safety applications to work properly. So, this helps to promote foresighted driving which aim to provide a comfortable, safer and more efficient traffic flow and this is realized by means of vehicle-to-vehicle or vehicle-to-infrastructure (V2X) communications including inter-vehicle communication that expands the horizon of drivers and provides alerts of possible dangerous situations ahead in time. In order to achieve a widely spread of V2X communications in the near future, where information can be reliably disseminated among vehicles in proximity with low latency using adaptive beaconing and transmission range approaches, a number of challenging issues have to be addressed. This paper discusses some issues that need to be considered by all researchers during the stage of analyzing the problem evaluation in order to efficiently enhance information dissemination and successful deployment of VANETs.
