Vehicle-to-vehicle communication—A vertical handover algorithm based on vehicle speed

Abstract

Vehicular communication is a part of intelligent transport system (ITS) which provides an intelligent way of transport to avoid accidents. Vehicle-to-Vehicle communication (V2V) is carried out through Vehicular Ad hoc Networks (VANET). This paper discusses about the MAC (Media Access Control) layer protocol, features of IEEE802.11p standard, and the handover protocol problems it is facing. Due to vehicle high speed and the non-homogeneous structure of the network infrastructure, support of connectivity by VANET is still a challenging task. In this paper, a vertical handover algorithm has been analyzed using vehicle speed, and the results have been supported by simulation.
