Communication Needs

The various sensors and wireless communication devices have been extensively applied to daily life due to the advancements of microelectronics mechanism and wireless technologies. Recently, vehicular communication systems and applications become more and more important to people in daily life. Vehicular communication systems that can transmit and receive information to and from individual vehicles have the potential to significantly increase the safety of vehicular transportation, improve traffic flow on congested roads, and decrease the number of people of deaths and injuries in vehicular collisions effectively. This system relies on direct communication between vehicles to satisfy the communication needs of a large class of applications, such as collision avoidance, passing assistance, platooning. In addition, vehicular communication systems can be supplemented by roadside infrastructure to access Internet and other applications. This system forms a special case of mobile ad hoc networks called Vehicle Ad Hoc Networks (VANETs). They can be formed between vehicles with vehicle to vehicle (V2V) communication or between vehicles and an infrastructure with vehicle to infrastructure (V2I) communication. The applications and characteristics of VANETs are introduced and presented in this Chapter.

The Impact

The advent of flying ad hoc networks (FANETs) has opened an opportunity to create new added-value services. Even though it is clear that these networks share common features with its predecessors, e.g., with mobile ad hoc networks and with vehicular ad hoc networks, there are several unique characteristics that make FANETs different. These distinctive features impose a series of guidelines to be considered for its successful deployment. Particularly, the use of FANETs for telecommunication services presents demanding challenges in terms of quality of service, energy efficiency, scalability, and adaptability. The proper use of models in research activities will undoubtedly assist to solve those challenges. Therefore, in this paper, we review mobility, positioning, and propagation models proposed for FANETs in the related scientific literature. A common limitation that affects these three topics is the lack of studies evaluating the influence that the unmanned aerial vehicles (UAV) may have in the on-board/embedded communication devices, usually just assuming isotropic or omnidirectional radiation patterns. For this reason, we also investigate in this work the radiation pattern of an 802.11 n/ac (WiFi) device embedded in a UAV working on both the 2.4 and 5 GHz bands. Our findings show that the impact of the UAV is not negligible, representing up to a 10 dB drop for some angles of the communication links.

Hoc Networks

Vehicular Ad hoc NETworks (VANETs) is an area under intensive research that promises to improve security on the road by developing an intelligent transport system (ITS). The main purpose is to create an inter-communication network among vehicles, as well as between vehicles and the supporting infrastructure. The system pretends to offer drivers data concerning other nearby vehicles, especially those within sight. The problem of information sharing among vehicles and between the vehicle and the infrastructure is another critical aspect. A general communication infrastructure is required for the notification, storage, management, and provision of context-aware information about user travel. Ideally an integrated vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication paradigm enriched with an information management system would solve the problem. The infrastructure should manage all the collected safety events garnered from vehicles and the interesting information to be provided to the user, which is adapted to the car context and driver preferences. Finally, security issues should be considered. Since the information conveyed over a vehicular network may affect critical decisions, fail-safe security is a necessity. The first directive for any V2V communication scheme is, therefore, that every safety message must be authenticated. Because of the high speed and therefore short duration within which communication between two cars is possible, communication must be non-interactive, and message overhead must be very low. The urgency of safety messages implies that authentication must be instantaneous without additional communication. Moreover, providing strong security in vehicular networks raises important privacy concerns that must also be considered. Safety messages include data that is dangerous to the personal privacy of vehicle owners. Most relevant is the danger of tracking a vehicle through positional information. A set of security basics to address these challenges should be proposed that can be used as the building blocks of secure applications. In this article we will focus on the aforementioned technologies and engineering issues related to vehicular ad-hoc networks, emphasizing the challenges that must be overcome to accomplish the desired vehicular safety infrastructure.

Communication Needs

The potential for vehicular applications is rapidly increasing. However this variety also demands a flexible multihop communication protocol supporting different communications needs and adapting to the network environment and to context elements specified by the application itself. We think that adaptive solutions, recently starting to be applied to VANET routing and dissemination protocols, have a great potential for solving the problems stated above. The objective of this chapter is to introduce the reader to these kinds of solutions, show their benefits and also mention the challenges involved. Because one important aspect of adaptive solutions (in this case a common communication protocol for all applications), is having in-depth knowledge of the problem to solve, we first review these different vehicular applications and their classification, followed by their communication needs.

The secure and efficient exchange of information in vehicular ad hoc networks (VANETs) involves more challenges than in any other type of ad hoc networks. This paper proposes a new vehicular communication system based on mobile phones for fully distributed and decentralized networks. In these networks, communications depend on individual nodes, which could decrease the efficiency and reliability of transmitted information. Besides, the limitation in the resources of mobile devices is an additional obstacle in the forwarding problem, and the content of the information generated by individual nodes must be considered inherently unreliable. In particular, this paper proposes the application of groups as a basis structure for a cooperation mechanism useful in event generation and in packet retransmission. Its aim is to promote the involvement of nodes in network performance. Given that such participation involves consumption of node resources, a group-based structure is here used not only to reduce communication overload but also to prevent sending false information and to encourage nodes in relaying packets. Several simulations of the proposal have been done, and the results have confirmed that this is a promising approach to increase network efficiency and trust in transmitted information, while reducing the number of selfish nodes in VANETs.

A special kind of Mobile ad-hoc networks (MANETs) is Vehicular ad -hoc networks (VANETs). The higher moving vehicles speed is the major issues relative with it. This affects the network instability and topological changes of communication routes. For VANETs, routing protocols is the difficulty that the research group mainly focus on. For vehicular communication, the familiar protocols of MANET proactive routing are used extensively. For VANET, they are not sufficient ones. In dynamic circumstances, route instability is the major issues with the protocols. To resolve the denoted issues, this work merges the PSO and multi-agent system methods and devised an improved PSO (i-PSO) algorithm. To examine the efficiency of our method, we have performed some experimentation. Superior results are exhibited by the proposed technique.

Distinguishing Property

Over the last few years Vehicular Ad hoc Networks (VANETs) have gained much attention within the automobile industry and the research applications. Vehicular Ad hoc networks (VANETs) are a subgroup of mobile adhoc networks (MANETs) with the distinguishing property that the nodes are vehicles like cars, trucks, buses and motorcycles. Nodes are expected to communicate by means of North American direct short-range communication (DSRC) standard [1] that employs the IEEE 802.11p standard for wireless communication and describes a MAC and PHY specifications for wireless connectivity. This chapter deals with the basic architecture of VANET and wired and wireless technology for intra-vehicular communication. Two prominent networking technologies such as Local Interconnect Network (LIN) and the Controller Area Network (CAN) for wired intra-vehicular communication have also been discussed. The objective of this chapter is to explain inter-vehicular communication and the components of a smart vehicle.

One of the key enablers of the evolving 5G technology are Vehicular Ad hoc Networks (VANETs) and Software Defined Networking (SDN). The development of next generation intelligent vehicular networks includes integration of SDN in Vehicular Ad hoc Networks (VANETs). Researchers have focused on the development of the integrated technology including architecture and benefits of SDN based VANET services. In this paper we have simulated the Vehicular Ad hoc Networks (VANETs) using Mininet-wifi. The VANET is incorporated with SDN controller. The performance is evaluated by varying the speed of vehicles. We have evaluated the performance in two ways: performance evaluation of V2V communication in same RSU and performance evaluation of V2V communication from different RSU. We have evaluated the proposed system for POX and RYU SDN OpenFlow controllers. As demonstrated in the results the RYU controller of SDN performs better as compared to POX controller in terms of average delay and throughput.

Vehicular Ad Hoc Networks (VANETs) are composed of vehicles equipped with advanced wireless communication devices. As a paradigm of decentralized advanced traveler information systems (ATIS), VANETs have obtained interests of researchers in both communication and transportation fields. The research in this chapter investigates several fundamental issues, such as the connectivity, the reachability, the interference, and the capacity, with respect to information propagation in VANETs. The authors’ work is distinguished with previous efforts, since they incorporate the characteristics of traffic into these issues in the communication layer of VANETs; this mainly addresses the issue of the interference. Previous efforts to solve this problem only consider static network topologies. However, high node mobility and dynamic traffic features make the interference problem in VANETs quite different. To investigate this problem, this chapter first demonstrates the interference features in VANETs incorporating realistic traffic flow features based on a validated simulation model. Then, analytical expressions are developed to evaluate the interference under different traffic flow conditions. These analytical expressions are validated within the simulation framework. The results show that the analytical expressions perform very well to capture the interference in VANETs. The results from this work can facilitate the development of better algorithms for maximizing throughput in the VANETs.
