“…Then, on the V2I uplink, the CHs aggregates the data of their cluster members before forwarding it to the eNB via LTE. In this way, the overall LTE traffic can be reduced compared to separate transmissions by individual vehicular users [47]. For the downlink, the multicast of the LTE network can be used to distribute messages.…”

With the rapid development of the Intelligent Transportation System (ITS), vehicular communication networks have been widely studied in recent years. Dedicated Short Range Communication (DSRC) can provide efficient real-time information exchange among vehicles without the need of pervasive roadside communication infrastructure. Although mobile cellular networks are capable of providing wide coverage for vehicular users, the requirements of services that require stringent realtime safety cannot always be guaranteed by cellular networks. Therefore, the Heterogeneous Vehicular NETwork (HetVNET), which integrates cellular networks with DSRC, is a potential solution for meeting the communication requirements of the ITS. Although there are a plethora of reported studies on either DSRC or cellular networks, joint research of these two areas is still at its infancy. This paper provides a comprehensive survey on recent wireless networks techniques applied to HetVNETs. Firstly, the requirements and use cases of safety and non-safety services are summarized and compared. Consequently, a Het-VNET framework that utilizes a variety of wireless networking techniques is presented, followed by the descriptions of various applications for some typical scenarios. Building such HetVNETs requires a deep understanding of heterogeneity and its associated challenges. Thus, major challenges and solutions that are related to both the Medium Access Control (MAC) and network layers in HetVNETs are studied and discussed in detail. Finally, we outline open issues that help to identify new research directions in HetVNETs. IndexTerms-Vehicle-to-Vehicle (V2V),

A vehicular network with Road Side Units (RSUs) provides an efficient way to connect vehicles even on the move. However, due to high deployment and maintenance cost of RSUs, it is necessary to use lesser number of RSUs such that total cost is minimized. It is suggested that cellular networks such as LTE are capable of fulfilling the demands posed in vehicular network scenarios. Availability of high bandwidth, large coverage area, and low latency are some of the advantages of cellular networks which help in overcoming the challenges of high speed vehicular communication. In this paper, we propose a maiden approach to analyse the performance of a vehicular network with cellular infrastructure as a backbone. For this, we use mobile femto access points as relays in place of RSUs. We model the network using M/M/m queue and compare the delay and throughput performance with traditional IEEE 802.11p vehicular networks. We also formulate an optimization problem and propose a subchannel power control algorithm to handle increased co-channel interference which emerges due to high mobility of vehicles in the network. Our suggested approach shows improvement in terms of delay, throughput, and energy efficiency. The results are verified using extensive simulations.Index Terms-Vehicular network, cellular network, mobile femto access points, delay, energy efficiency.

“…Recently, there exist some works that advocate about their combination in vehicular communications [9,18,19,20,21,22,23], although they do not deal specifically with the content distribution problem in store-carry-and-forward networks. In particular, in [21] the authors propose the use of a 3G cellular network to gather and distribute relevant control information (e.g., connectivity in the di↵erent roads) with the goal of improving the routing process over the VANET.…”

Similarly, in [23] LTE is used to organize the vehicular network into clusters and to maintain this structure over the time. On the contrary, in [22] the cellular network is used to exchange data when there is not a multi-hop VANET path between the source and destination vehicles.…”

This is a preprint version of the following published document:Urueña, M., Soto, I., Martínez-Yelmo, I., Calderón, M., 2017, "Effect of content popularity, number of contents and a cellular backup network on the performance of content distribution protocols in urban VANET scenarios", Computer Communications, V. 99, p. 13-23. Abstract Di↵erent types of infotainment and tra c e ciency applications make use of content distribution protocols in vehicular networks. Current research on content distribution has been focused on designing e cient protocols, but it has put little e↵ort in modeling the nature of the applications that consume and generate those contents, or in studying the internetworking with cellular networks. This paper studies the e↵ects of application characteristics on the performance of push-and pull-based content distribution protocols in VANETs. In particular, it considers the total number of contents being distributed, the popularity of those contents, and the utilization of a cellular backup network to guarantee a level of service for delay-bounded applications. We also propose the Multi-Hop To Infostation (MHTI) protocol: a pullbased, multi-hop protocol that sends content requests towards the closest infostation. Requests can be satisfied before reaching the infostation by any vehicle in the path that has cached the requested content. Our analysis indicates that the performance of push-and pull-based protocols is only satisfactory in scenarios with a low number of contents or highly popular ones, while MHTI also exhibits a good performance with a large number of contents, and it takes advantage from di↵erent content popularities to obtain ⇤ Corresponding author
