Abstract

Vehicular ad-hoc Networks (VANETs) are recognized as a cornerstone of Intelligent Transportation Systems (ITS) to enable the exchange of information among vehicles, which is crucial for the provision of safety-related and entertainment applications. However, practical useful realizations of VANETs are still missing, mainly because of the elevated costs and the lack of a final standardization. In this regard, the feasibility of using smartphones as nodes in VANETs has been explored focusing on small-scale deployments to mainly validate single-hop communication capabilities. Moreover, existing smartphone-based platforms do not consider two crucial requirements in VANETs, namely, multi-hop communication and the provision of security services in the message dissemination process. Furthermore, the problem of securing message dissemination in VANETs is generally analyzed through simulation tools, while performance evaluations on smart devices have not been reported so far. In this paper, we aim to fill this void by designing a fully on-device platform for secure multi-hop message dissemination. We address the multi-hop nature of message dissemination in VANETs by integrating a location-based protocol that enables the selection of relay nodes and retransmissions criteria. As a main distinction, the platform incorporates a novel certificateless cryptographic scheme for ensuring data integrity and nodes’ authentication, suitable for VANETs lacking of infrastructure.

Highlights

As population densities increase in large cities around the world, the need of novel vehicular traffic management solutions for assuring safety while maintaining congestion at acceptable levels has become more evident
We have narrowed down the experimental trials to mainly validate the impact of the proposed a Certificateless Signature Scheme (ACSS) scheme on the performance of the message dissemination process

Summary

Introduction

As population densities increase in large cities around the world, the need of novel vehicular traffic management solutions for assuring safety while maintaining congestion at acceptable levels has become more evident. Intelligent transportation systems (ITS) are expected to fill this need, relieving congestion and improving safety [1] This is achieved by integrating advanced wireless and wireline communication, sensor and processing technologies into transportation systems, and into vehicles themselves, in order to develop a wide range of applications (e.g., crash prevention and safety, freeway management, etc.). Such in-vehicle communication and computation capabilities are expected to enable vehicles to autonomously cooperate among themselves to share information about their surrounding [2]. Depending on the communication paradigm, a vehicle can communicate to another vehicle, to a road side unit, or to a pedestrian handling a portable device, assuming a vehicle-to-vehicle (V2V), Sensors 2020, 20, 330; doi:10.3390/s20020330 www.mdpi.com/journal/sensors
