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.

Scientific Essay from the year 2015 in the subject Engineering - Communication Technology, Arab International University, course: Digital Communications, language: English, abstract: In the last decades, the increasing demands on communication systems have required more development and improvement on the communicating technologies. While many scientists agree that the classical frequency division multiple access technique for communicating is a de-facto standard, new generations of communications devices require more efficient techniques such as the time division multiple access technology. This paper identifies the methods of using time division multiple access as an alternative to the original frequency division transmission technique. The paper clarifies the principle of multiple access technologies, and compares the old method with the newest one. This study points out the ways of replacing the frequency division with the time division multiple access, and identifies the main obstacles that might be faced.

For any type of transportation system, traffic safety is a global concerned issue that attracts the most attentions. Within the U.S only, millions of crashes happen every year, leaving tons of deaths and tremendous economic losses. Therefore, considerable efforts from research institutes, governments, and industry have been undertaken to reduce or even eliminate traffic accidents. Intelligent Transportation System (ITS) has been developed to enhance traffic safety by using Vehicle-to-Vehicle (V2V) or Vehicle-to-Roadside (V2R) communications. ITS allows a vehicles that equipped with wireless communication devices to exchange information with its neighbors or roadside data centers. That is to say, vehicles are no longer isolated, but can make up Vehicular Ad Hoc Networks (VANETs), a special form of Mobile Ad Hoc Networks (MANETs), which allow inter-vehicle communications. VANETs make "smart vehicle", which is able to avoid traffic accident spontaneously, become possible. However, numbers of challenges are faced by researchers to make the VANET efficient and feasible enough in the real-world circumstance. One of the primary challenges of current VANETs study is to achieve real-time information exchange among vehicles for enhancing traffic safety. To achieve this goal, information dissemination requires timely and lossless wireless medium access, which brings new difficulties to the design of MAC (Medium Access Control) protocols. In this thesis, we propose a clustering-based multi-channel V2V communication system to provide traffic accident avoidance mechanism. In the proposed system, vehicles are self-organized into different clusters, and the traditional single common medium in a MANET has been divided into multiple control channels and a single data channel. Since a GPS (Global Positioning System) is easy to equip into a vehicle and provide synchronized standard time, infrastructure-based TDMA/CDMA (Time Division Multiple Access/Code Division Multiple Access) technique is adopted for intra-cluster and inter-cluster data communications. For the control channels, a contention-based IEEE 802.11 MAC protocol is utilized to coordinate the medium access in a fully distributed manner. A novel TDMA/CDMA hybrid MAC protocol is designed for the data channel to achieve low transmission delay. Another contribution of this research work is the systematic study of the highway traffic model. To the best of our knowledge, most V2V communication systems proposed so far were built on an extremely simple highway model, which means not feasible in the real world. However, the highway traffic model designed in this research work is based on the real-world environment, whose vehicles are allowed to performance real driving behaviors. This advanced highway traffic model makes our proposed V2V communication system can be used in any type of road condition. A sophisticated event-driven simulator has been developed by C++ language. The system is evaluated by extensive simulations. The simulation results show that the proposed system can provide better performance for safety supporting than most existing schemes.

This book investigates intelligent network resource management for IoV, with the objective of maximizing the communication and computing performance of vehicle users. Focusing on two representative use cases in IoV, i.e., safety message broadcast and autonomous driving, the authors propose link-layer protocol design and application-layer computing task scheduling to achieve the objective given the unique characteristics and requirements of IoV. In particular, this book illustrates the challenges of resource management for IoV due to network dynamics, such as time-varying traffic intensity and vehicle mobility, and presents intelligent resource management solutions to adapt to the network dynamics. The Internet of Vehicles (IoV) enables vehicle-to-everything connectivity and supports a variety of applications for vehicles on the road. Intelligent resource management is critical for satisfying demanding communication and computing requirements on IoV, while the highly dynamic network environments pose challenges to the design of resource management schemes. This book provides insights into the significance of adaptive resource management in improving the performance of IoV. The customized communication protocol and computing scheduling scheme are designed accordingly by taking the network dynamics information as an integral design factor. Moreover, the decentralized designs of the proposed solutions guarantee low signaling overhead and high scalability. A comprehensive literature review summarizing recent resource management schemes in IoV, followed by the customized design of communication and computing solutions for the two IoV use cases is included which can serve as a useful reference for professionals from both academia and industry in the area of IoV and resource management. Researchers working within this field and computer science and electrical engineering students will find this book useful as well.
