Über dieses Buch

This book presents link-layer cooperative frameworks to improve transmission reliability and network throughput of distributed TDMA MAC protocols in vehicular ad hoc networks (VANETs). The main objective of this book is to present link-layer node cooperation schemes to enhance the link-layer performance of vehicular networks, in terms of reliability and system throughput. The authors present approaches proposed for the medium access control (MAC) and node cooperation in VANETs. The authors also cover cooperative ADHOC MAC for point-to-point communication between a pair of source and destination nodes, and cooperative relay broadcasting for broadcast services in this book. The performance of node cooperation frameworks is evaluated via mathematical analysis and computer simulations, in comparison with distributed TDMA MAC protocols without cooperation. The proposed node cooperation frameworks enhance the performance of distributed TDMA MAC and make it more robust to tackle the dynamic networking conditions in VANETs. Furthermore, with cooperation enabled transmission, the performance of distributed TMDA MAC is more suitable to support the wide range of mobile applications and their strict service requirements which is discussed in this book.

The proposed node cooperation schemes and distributed cooperation decisions can be extended to wireless systems other than distributed TDMA MAC, such as cellular communication, for vehicular communications introduced in this book. This book is useful for researchers from academia and industry, as well as advanced level students interested in vehicular communication networks. It is also useful for professionals and engineers developing applications that use cooperative wireless communication systems.

Chapter 1. Introduction
Abstract
The increasing number of road accidents and more frequent traffic congestion have resulted in the evolution of intelligent transportation systems (ITS) [6] and other mobile distributed applications which improve road safety, increase transportation efficiency, and provide on-board infotainment. On the other hand, the rapid advancement of wireless communication technology and automotive industries have led to the paradigm of vehicular ad hoc network (VANET) as a promising approach to provide a communication infrastructure supporting ITS and other on-board applications, primarily to improve road safety. In VANETs, vehicles are equipped with various onboard sensors, which gather information, and communication devices, which provide networking interface to exchange the gathered information through wireless medium. According to the National Highway Traffic Safety Administration (NHTSA) of the United States Department of Transportation (USDoT), traffic accidents, specifically unimpaired vehicle crashes, can be reduced by approximately 80% through the deployment of road safety applications enabled by VANETs [7]. In addition, comfort related applications such as gaming, automatic toll collection, drive-thru Internet connections, multimedia services are expected to be delivered to vehicles for their drivers and passengers, providing on-board infotainment services [8–10].

Chapter 2. Background and Literature Review
Abstract
This chapter provides the background information of VANETs that is related to our research. In reviewing recent literature, approaches proposed for the medium access control (MAC) in single-channel VANETs are presented. In addition, cooperative MAC protocols and cooperation based makeup transmission frameworks proposed in the literature in order to improve performance of wireless networks are discussed.

Chapter 4. Cooperation in ADHOC MAC
Abstract
This chapter presents a node cooperation scheme, referred to as (CAH-MAC), mainly focusing on the MAC layer in VANETs (Bharati and Zhuang, Performance analysis of cooperative ADHOC MAC for vehicular networks, in Proceedings of IEEE Global Communications Conference (GLOBECOM), 2012; Bharati and Zhuang, IEEE J Sel Areas Commun. 31(9):470–479, 2013). Existing works on link-layer cooperation are not suitable for VANETs scenarios and cannot be applied directly. Different from the existing works, here we consider a VANET using a distributed TDMA based MAC. In the system, nodes reserve their time slots and nearby nodes form a cluster to share a time frame. For cooperation at the link layer, a helper node utilizes an idle time slot to relay a packet that a source node failed to deliver to the target destination node in a direct transmission due to a poor channel condition. Furthermore, cooperative relay transmissions in the proposed node cooperation scheme do not affect normal (non-cooperation) transmissions. Using idle time slots for the cooperative relay transmissions, the proposed CAH-MAC protocol improves system throughput and transmission reliability of the D-TDMA MAC for VANETs. We derive a close-form expressions for the throughput and packet dropping rate of the newly proposed CAH-MAC protocol, which is verified using simulations. Our analysis shows that the CAH-MAC protocol achieves a higher throughput and a lower packet dropping rate than that of the ADHOC MAC under a similar networking condition.

Chapter 5. Enhanced Node Cooperation
Abstract
Transmission collisions occur, refereed to as cooperation collisions, in D-TDMA MAC with the introduction of node cooperation in the presence of relative node mobility and channel fading. In this chapter, we present an improvised CAH-MAC with a collision avoidance scheme, referred to as enhanced CAH-MAC (eCAH-MAC) (Bharati et al., Proceedings of IEEE International Conference on Communications (ICC), 2013; Bharati et al., IEEE Trans Veh Technol, to appear). In eCAH-MAC, cooperative relay transmission is suspended if there is (are) any transmission attempt(s) from the one-hop node(s) of the destination and/or helper nodes, avoiding cooperation collision. Cooperative relay transmission is performed only if the destination and helper nodes do not detect transmissions in their one-hop neighborhood. Through mathematical analysis and simulations, we show that the proposed collision avoidance scheme increases the utilization of unreserved time slots by either allowing them to be reserved by nodes seeking their own time slots or using them to perform cooperative relay transmissions, without disrupting the D-TDMA MAC normal operations. Furthermore, through extensive simulations we study the performance of eCAH-MAC in the presence of vehicle mobility over a generalized Nakagami channel.

Chapter 6. Cooperative Relay Broadcasting
Abstract
Delay sensitive safety applications demand an efficient, quick, and reliable broadcast service. The existing D-TDMA MAC protocols may not be able to achieve the required QoS if the source node rebroadcasts the packet. Hence, it is necessary for the D-TDMA MAC to have a makeup strategy that provides a quick and reliable one-hop broadcast service specifically to satisfy the strict QoS requirements of the delay sensitive safety applications in VANETs. In this chapter, we present node cooperation based makeup transmission framework for D-TDMA MAC in VANETs, referred to as cooperative relay broadcasting (CRB). In CRB, nodes with packet from a source node rebroadcast the packet before it expires, making it suitable for delay sensitive safety applications with strict QoS requirements.

Chapter 7. Conclusions and Future Works
Abstract
Vehicular ad hoc networks will be an essential component of intelligent transportation systems, to enable a wide range of mobile distributed applications to improve the safety and efficiency of vehicle transportation and support onboard passenger infotainment. The existing MAC approaches for VANETs are not free from packet dropping and throughput reduction due to the dynamic networking conditions and are not always suitable to support the wide range of mobile distributed applications. On the other hand, link-layer node cooperation can be used to improve the performance, establishing a more efficient, robust and reliable communication among nodes. However, the existing link-layer node cooperation schemes are not suitable for the vehicular dynamic networking conditions and cannot be applied directly to VANETs. Thus, this book presents node cooperation frameworks at the MAC layer of VANETs to provide efficient and reliable communication to support the wide range of applications with strict service requirements, and to provide more robust communication to tackle the dynamic networking conditions.
