7 New Robust Protocol for IoV Communications

ABSTRACT.– First, this chapter presents some definitions of vehicle networks, application areas, communication technologies and barriers that disrupt communications and deteriorate quality of service (QoS) in the Internet of Vehicles (IoV). Then, it introduces our proposition aiming to detect and bypass disconnection zones through a new routing protocol based on (1) the estimation of the contact time between a vehicle and its neighbors, (2) the data load to be transferred and (3) logs of communication errors. The objective is to ensure the availability, the reliability and the robustness of inter-vehicle communications by taking these three criteria into account in a data routing algorithm.

7.1. Introduction

The new era of the Internet of Things (IoT) has spurred the evolution of classic ad hoc vehicular networks (VANETs) toward the paradigm of the Internet of Vehicles (IoV). This type of network is formed mainly of on-board units (OBUs) installed in vehicles and terminals installed along roads (Road Side Units, or RSUs). The types of communication in vehicular networks are called “V2X”, where X refers to a vehicle (V2V), an infrastructure (V2I), a person (V2P) or any other connected object (V2O). Because of its characteristics, the IoV is considered as a part of the IoT, where the objects are vehicles, enabling the creation of a multitude of services dedicated to the intelligent transport ecosystem [GER 16, REH 15].
