Abstract: A vehicular ad hoc network (VANET) is a packet-switched network, consisting of mobile communication nodes mounted on vehicles, with very limited or no infrastructure support [1]. It supports communications among nearby vehicles, and between vehicles and nearby infrastructure/users, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-roadside unit (V2R), vehicle-to-pedestrian (V2P) communications, collectively referred to as vehicle-to-everything (V2X) communications [2]. The paradigm of VANETs will improve road safety, facilitate intelligent transportation, support infotainment, data sharing, and location based services, and will be a critical component in the future Internet of Things. The growing importance of vehicular communication networks has been recognized by governments, academia, and industry worldwide.

The Federal Communications Commission in the United States has approved a radio spectral width of 75 MHz for Dedicated Short Range Communications (DSRC). Transport Canada supports the introduction of DSRC-based intelligent transportation applications in the frequency band 5850-5925 MHz. It is expected that the DSRC system will be the first wide-scale vehicular network in North America. The latest version of DSRC, IEEE 1609 Family of Standards for Wireless Access in Vehicular Environments (WAVE) [3] with IEEE 802.11p for channel access [4] has emerged for vehicular communications. In Europe, a car-to-car communication consortium has been initiated by European vehicle manufacturers, and is dedicated to further increase road traffic safety and efficiency by means of inter-vehicle communications [5]. The European Telecommunications Standards Institute (ETSI) has developed the intelligent transport systems (ITS) G5 standards for vehicular networks to operate on the 5 GHz radio frequency band [6], based on IEEE 802.11p physical and link layers. In Japan, the Association of Radio Industries and Businesses (ARIB) has issued the ARIB STD T-109 standard for vehicular communications using TV white space in the 700 MHz band [7]. In particular, the China Communications Standards Association (CCSA), together with the China telecom industry, has been actively participating in the 3GPP initiatives on LTE support for connected vehicles [8].

VANETs provide a promising platform for future deployment of large scale and highly mobile network services. Given the automobile’s role as a critical component in our society, embedding Information and Communication Technology (ICT) services into automobiles has the potential to significantly improve our quality of life. This, along with great market demand for more reliability, safety, and entertainment value in automobiles, has led to many initiatives and support for deployment of vehicular networks and applications. The research and development activities for connecting vehicles via advanced communication and information technology have reached to a tipping point for significant impacts on society, economy, and daily life of ordinary people. Vehicular networks have unique networking characteristics, including highly dynamic network topology, distributed network control in peer-to-peer communications, and stringent service quality requirements for safety applications such as delay and packet delivery reliability. As a result, it provides both challenges and opportunities for further R&D activities in order to achieve reliable, secure, accurate, and fast end-to-end information delivery in VANETs.

This special issue aims to present some recent research works for vehicular communication technology and its potential applications. It includes five technical contributions from leading researchers in vehicular communication networks. The first paper entitled “On Coexistence of Vehicular Overlay Network and H2H Terminals on PRACH in LTE” by Khan, Misic and Misic presents how to use the LTE physical random access channel (PRACH) to support vehicular machine-to-machine (VM2M) communications, and analyzes the impact of PRACH format and configuration parameters on the performance of VM2M subnetworks. The second paper is entitled “A Cooperative Forwarding Scheme for VANET Routing Protocols” by WU, JI, and YOSHINAGA. It focuses on how to improve the end-to-end packet delivery ratio in unicast routing protocols via multiple forwarding nodes and network coding. Numerical results demonstrate that the proposed strategies can improve the packet delivery ratio without increasing message overhead. The third paper, co-authored by HE and CAI, studies hybrid content distribution framework for large-scale vehicular ad hoc networks. It introduces a hybrid network solution to address scalability issue of content distribution in large-scale vehicular ad hoc networks. An overlay store-carry-and-forward content distribution network is established to model a large-scale VANET, and utility-based optimization is formulated to find optimal data packet routing solutions. The next paper, co-authored by YANG, ZHENG, LEI, and XIANG, is entitled “Heterogeneous Vehicular Networks for Social Networks: Requirements and Challenges”. It presents two social network architectures that embed social characteristics into heterogeneous vehicular networks. It discusses several use cases to analyze service requirements and associated challenges. The last (but not least) paper “A Cloud Computing Perspective for Distributed Routing in Vehicular Environments” is co-authored by Shivshankar and Jamalipour. It presents how to effectively apply cloud computing to address challenges of the spatio-temporal multicast (SMRP) distributed routing in VANETs. It proposes a new mechanism to exploit cloud computing in the routing process, which can increase service discovery rate and reduce the required resource and service discovery download time with roadside units and internet, in comparison with the vehicular clouds obtained directly through the SMRP based routing.

We would like to thank all the authors for choosing this special issue to publish their new research results, all the reviewers for their meticulous review comments and suggestions which help to improve the technical quality and presentation of this special issue, and the editorial official of ZTE Communications for all the support and help during the editorial process of this special issue. We hope that our readers will enjoy reading the articles and find this special issue helpful to their own research work. Working together, we will make connected vehicles and Internet of vehicles a reality in the near future.
