Achieving broadcasting efficiency in V2X networks with a distance-based protocol

Vehicular wireless networks are prospective tools which contribute to safer and more efficient roads. Therefore, they require the design and development of new communication protocols that should constitute the building blocks of future vehicular communication architecture. Many works have been carried out in this wide research area. In this paper, we propose a reliable distance-based broadcast protocol to deliver safety information to nodes located in a geographical area when an emergency event occurs. Simulation results show that the proposed protocol achieves its design goal of delivering information in a rapid and efficient manner. Furthermore, we conclude that our proposal performs better in terms of information reception delay as well as redundancy factor as compared to a scheme inspired from previous proposed schemes.
