“…It is a distinct category of Mobile Ad-hoc Network (MANET) [4], which consists of a set of high-speed and high-mobility vehicles equipped with sensors and communication devices [5]. It transforms each neighboring vehicle into a wide-range, wireless, ad-hoc network that enables vehicles to establish interconnection links and share information with each other wirelessly using a dedicated short-range communication (DSRC) protocol [6][7][8]. VANET can significantly enhance the driving experience by supporting critical vehicular safety applications, such as emergency or hazard warning, vehicle collision avoidance, traffic status broadcast, road condition sharing and lane-changing assistance [3].…”

Vehicular Ad-hoc Network (VANET) facilities envision future Intelligent Transporting Systems (ITSs) by providing inter-vehicle communication for metrics such as road surveillance, traffic information, and road condition. In recent years, vehicle manufacturers, researchers and academicians have devoted significant attention to vehicular communication technology because of its highly dynamic connectivity and self-organized, decentralized networking characteristics. However, due to VANET's high mobility, dynamic network topology and low communication coverage, dissemination of large data packets (e.g. multimedia content) is challenging. Clustering enhances network performance by maintaining communication link stability, sharing network resources and efficiently using bandwidth among nodes. This paper proposes a mobility-based, multi-hop clustering algorithm, (MBCA) for multimedia content broadcasting over an IEEE 802.11p-LTE-enabled hybrid VANET architecture. The OMNeT++ network simulator and a SUMO traffic generator are used to simulate a network scenario. The simulation results indicate that the proposed clustering algorithm over a hybrid VANET architecture improves the overall network stability and performance, resulting in an overall 20% increased cluster head duration, 20% increased cluster member duration, lower cluster overhead, 15% improved data packet delivery ratio and lower network delay from the referenced schemes [46], [47] and [50] during multimedia content dissemination over VANET.

Efficient protocols for data packet delivery in Vehicular Ad-hoc NETworks (VANETs) are crucial to guarantee the correct forwarding of data. However, communication in VANETs is a challenging task not only for the high mobility of the vehicles, but as recent studies have shown, there is a negative impact on protocol performances caused by an obstacle such as another vehicle in the line-of-sight (LOS). Many different routing protocols were presented in the last years, but only few of them were considering the effect of non line-of-sight (NLOS) propagation. In this work, we present a new solution to improve the data packet delivery ratio considering the problems caused by a high mobility and NLOS condition. Our proposal can be integrated in every position-based routing protocol. In fact, our method creates a support context awareness of neighbors before letting the protocol choose the next hop, without interfering with the specific logic. Simulation results of our context-aware version have been compared with the original protocols and with a modified version in accordance with the principle that every violation of LOS involves a discard of the packet: our solution always perform better in terms of packet delivery ratio and delay.

Internet of vehicles (IoV) promises to provide ubiquitous information exchange among moving vehicles and reliable connectivity to the internet. Therefore, IoV is becoming more and more popular as the number of connected vehicles is increasing. However, the existing vehicular communication infrastructure cannot guarantee reliable connectivity because alltime information exchange for every travelling vehicle is not assured due to lack of required number of roadside units (RSUs) especially along the intercity highways. This study is aimed towards exploring the use of cost-effective dynamic deployment of RSUs based upon the road traffic density and by ensuring the Line of Sight (LOS) among RSUs and Cellular Network Antennas. The unmanned aerial vehicles (UAVs) have a potential to serve as economical dynamic RSUs. Therefore, the use of UAVs along the roadside for providing reliable and ubiquitous information exchange among vehicles is proposed. The UAVs will be deployed along the roadside and their respective placement will be changed dynamically based upon the current traffic density in order to ensure the all-time connectivity with the travelling vehicles and the other UAVs/Cellular Network antennas. The reliability of the proposed network will be tested in terms of signal strength and packet delivery ratio (PDR) using the simulation.

INTRODUCTIONVehicular Ad Hoc Networks (VANETs) [1] provide vehicle to infrastructure (V2I) and vehicle to vehicle (V2V) communication in order to deliver extensive range of applications spanning from infotainment to safety related applications [2,3]. VANET is gradually evolving into Internet of Vehicles (IoV) that provides internet access to the travelling vehicles in addition to the inter-vehicular communication [4,5]. The popularity of IoV is increasing rapidly due to its huge potential in terms of connectivity and a wide range of advantageous applications [6]. The modern vehicular communication also offers accident detection [7]. The communication in VANETs depends on the Roadside Unit (RSU) [8]. However, this massive connectivity requires optimal deployment of communication infrastructure; in which roadside units (RSUs) are important component. RSUs provide the essential link among the vehicles and other infrastructure components to fulfill the connectivity challenges of IoV [9]. RSUs connect the vehicles to the other vehicles which are outside their radio range and also with the infrastructure components in order to provide internet access to the vehicles on the road [10].A comprehensive strategy for installation of RSUs is proposed in [10]. In [11], RSUs are placed by utilizing geometrical methods to improve the LOS among communicating vehicle in modern road infrastructure units. Another scheme introduces deployment of RSUs efficiently in modern roads using approximation algorithm [12]. A similar approach is used in [13]. Most of the e...
