Internet of Vehicles (IoV) is viewed as a developing worldview for associated vehicles to trade their data with different vehicles utilizing vehicle-to-vehicle (V2V) correspondences by framing a vehicular ad-hoc systems (VANETs), with roadside units utilizing vehicle-to-roadside (V2R) interchanges. Performance of this smart ITS mainly owes to the design of efficient routing protocols in VANETs. Distinct features of VANETs like unsteady connectivity, high mobility and partitioning of the network have made routing of the information in VANETs difficult and challenging, hence dictating the development of efficient routing protocols. The computation of the best route measures the performance of communication whereas routing protocols takes care of communication & routing of the data. Provision of smart communication, necessitates the analysis of routing protocols in VANET. Accordingly in this paper, reviewed various types of existing routing protocols and security approaches in VANET are discussed.

V2v Communications

In the framework of the Internet of Things (IoT) and more specifically the Internet of Vehicles (IoV), vehicles are called upon to play a key role as mobile sensors. Their high mobility and the large amount of electronics they currently deploy allow them to act as mobile information collectors in the places where they circulate. Together with these capabilities, the deployment of communications systems that allow them to share this information will make possible the massive deployment of the so-called Cooperative Intelligent Transport Systems (C-ITS). In this context, this article presents RODEO as a methodology that allows vehicles to use the current mobile communications systems to make V2V (Vehicle to Vehicle) communications, minimizing the number of resources needed. This paper analyses the performance of RODEO (Rrm fOr unDerlay vEhicle cOmmunications) from the perspective of energy performance, understood as the number of bytes transmitted per watt consumed.

Given a scenario of Vehicle Ad hoc Network (VANET), this paper presented a GIS-Based routing (GBR) strategy to resolve frequent reconstruction caused by rapid topology changes. Due to the use of road information based on GIS, the protocol can evade permanent or temporary topology holes respectively which frequently occurred in the city scenario. Simulation results showed new routing protocols could achieve better performance in packet delivery ratio and proved GBR’s lower routing overhead, as well as it is better performances in high mobility, compared with DSR in urban vehicle environment.

Over the last decade vehicle-to-vehicle (V2V) communication has received a lot of attention as it is a crucial issue in intravehicle communication as well as in Intelligent Transportation System (ITS). In ITS the focus is placed on integration of communication between mobile and fixed infrastructure to execute road safety as well as nonsafety information dissemination. The safety application such as emergence alerts lays emphasis on low-latency packet delivery rate (PDR), whereas multimedia and infotainment call for high data rates at low bit error rate (BER). The nonsafety information includes multimedia streaming for traffic information and infotainment applications such as playing audio content, utilizing navigation for driving, and accessing Internet. A lot of vehicular ad hoc network (VANET) research has focused on specific areas including channel multiplexing, antenna diversity, and Doppler shift compensation schemes in an attempt to optimize BER performance. Despite this effort few surveys have been conducted to highlight the state-of-the-art collection on Doppler shift compensation schemes. Driven by this cause we survey some of the recent research activities in Doppler shift compensation schemes and highlight challenges and solutions as a stock-taking exercise. Moreover, we present open issues to be further investigated in order to address the challenges of Doppler shift in VANETs.

The new age of the Internet of Things (IoT) is motivating the advancement of traditional Vehicular Ad-Hoc Networks (VANETs) into the Internet of Vehicles (IoV). This paper is an overview of smart and secure communications to reduce traffic congestion using IoT based VANETs, known as IoV networks. Studies and observations made in this paper suggest that the practice of combining IoT and VANET for a secure combination has rarely practiced. IoV uses real-time data communication between vehicles to everything (V2X) using wireless communication devices based on fog/edge computing; therefore, it has considered as an application of Cyber-physical systems (CPS). Various modes of V2X communication with their connecting technologies also discussed. This paper delivers a detailed introduction to the Internet of Vehicles (IoV) with current applications, discusses the architecture of IoV based on currently existing communication technologies and routing protocols, presenting different issues in detail, provides several open research challenges and the trade-off between security and privacy in the area of IoV has reviewed. From the analysis of previous work in the IoV network, we concluded the utilization of artificial intelligence and machine learning concept is a beneficial step toward the future of IoV model.

In the recent years, the study and developments of networks that do not depend on any pre-existing infrastructure have been very popular. Vehicular Ad Hoc Networks (VANETs) belong to the class of these networks, in which each vehicle participates in routing by transmitting data for other nodes (vehicles). Due to the characteristics of VANET (e.g. high dynamic topology, different communication environment, frequently link breakage…), the routing process still one of the most challenging aspects. Hence, many routing protocols have been suggested to overcome these challenges. Moreover, routing protocols based on the position of vehicles are the most popular and preferred class, thanks to its many advantages like the less control overhead and the scalability. However, this class suffer from some problems such as frequent link breakages caused by the high-mobility of vehicles, which cause a low PDR and throughput. In this investigation, we introduce a novel greedy forwarding strategy used to create a new routing protocol based on the position of vehicles, to reduce the link breakages and get a stable route that improves the PDR and throughput. The proposed Density and Velocity (Speed, Direction) Aware Greedy Perimeter Stateless Routing protocol (DVA-GPSR) is based on the suggested greedy forwarding technique that utilizes the density, the speed and the direction for selecting the most convenient relaying node candidate. The results of simulation prove that DVA-GPSR protocol outperforms the classical GPSR in all studied metrics like PDR, throughput, and the ratio of routing overhead by changing the quantity of vehicles in urban and highway scenarios.

In high mobility and high traffic load network situations, the delay time is affected with high end-to-end delay in reactive routing protocols such as AODV. In this paper we proposed an enhanced receiver-based AODV (ERB-AODV) routing protocol by improving the maintenance phase in AODV. ERB-AODV protocol focuses on decreasing the end-to-end delay and the control overhead in high mobility and traffic load. The receiver node uses a controller agent to update the sender node of the current available path. The agent works depend on the history of receiving data packets. Using glomosim, the ERB-ADOV protocol outperforms the AODV protocol in high mobility and traffic load. Results show that, in high mobility, the delay is decreased by 81% and the control overhead is decreased by 77%. The delay is decreased by 91% in high traffic load, and decreases the control overhead by -77% compared with AODV protocol. These results show the improvement of network delay using the new maintenance strategy on on-demand routing protocols for MANETs.

With the advancement in communication technologies, Internet of vehicles presents a new set of opportunities to efficiently manage transportation problems using vehicle-to-vehicle communication. However, high mobility in vehicular networks causes frequent changes in network topology, which leads to network instability. This frequently results in emergency messages failing to reach the target vehicles. To overcome this problem, we propose a data dissemination scheme for such messages in vehicular networks, based on clustering and position-based broadcast techniques. The vehicles are dynamically clustered to handle the broadcast storm problem, and a position-based technique is proposed to reduce communication delays, resulting in timely dissemination of emergency messages. The simulation results show that the transmission delay, information coverage, and packet delivery ratios improved up to 14%, 9.7%, and 5.5%, respectively. These results indicate that the proposed scheme is promising as it outperforms existing techniques.
