Safety-message Routing in Vehicular Ad Hoc Networks available in PDF, EPUB and Kindle. The safety-message dissemination problem for vehicular ad hoc networks (VANETs) was investigated. Four novel techniques were contributed for the efficient and reliable routing of safety messages in the vehicular ad hoc networks. The instant-broadcast technique was proposed to improve the end-to-end dissemination delay. The lane-based sectoring mechanism was presented for the collision mitigation in the dense-urban traffic scenario. The negative acknowledgment with smart neighborhood (NSN) technique was proposed to ensure the reliability of reception through recovering the packet loss caused by interference. Finally, the negative acknowledgment with smart neighborhood - hole recovery (NSN-H) technique was presented to provide guaranteed reception of the safety message at each individual node in the VANET. The investigation of the safety message routing in VANET conducted in this research also revealed the significance of hitherto-neglected factors that influence the vehicular network. Significance of the small payload size of the VANET safety message, the effect of road width on the multi-hop relay, and the attenuation caused by vehicles in the propagation path were among the important revealed factors.

Bio-inspired Routing Protocols for Vehicular Ad-Hoc Networks available in PDF, EPUB and Kindle. Vehicular Ad-Hoc Networks (VANETs) play a key role to develop Intelligent Transportation Systems (ITS) aiming to achieve road safety and to guaranty needs of drivers and passengers, in addition to improve the transportation productivity. One of the most important challenges of this kind of networks is the data routing between VANET nodes which should be routed with high level of Quality of Service (QoS) to ensure receiving messages in the time. Then, the driver can take the appropriate decision to improve the road safety. In the literature, there are several routing protocols for VANETs which are more or less reliable to reach safety requirements. In this book, we start by describing all VANET basic concepts such as VANET definition, VANET versus Mobile ad-Hoc Network (MANET), architectures, routing definition and steps, Quality of Service (QoS) for VANET Routing, Metrics of evaluation, Experimentation, and simulation of VANETs, mobility patterns of VANET etc. Moreover, different routing protocols for routing in VANETs will be described. We propose two main categories to be presented: classical routing and bio-inspired routing. Concerning classical VANET, main principles and all phases will be overviewed, as well as, their two sub-categories which are topological and geographical protocols. After that, we propose a new category called bio-inspired routing which is inspired by natural phenomenon such as Ant colony, Bee life, Genetic operators etc. We present also, some referential protocols as example of each category. In this book, we focus on the idea of how to apply bio-inspired principle into VANET routing to improve road safety, and to ensure QoS of vehicular applications.

Download and read online ebook Safety Message Broadcast in Vehicular Networks write by Yuanguo Bi. This book was released on 2016-12-16. Safety Message Broadcast in Vehicular Networks available in PDF, EPUB and Kindle. This book presents the current research on safety message dissemination in vehicular networks, covering medium access control and relay selection for multi-hop safety message broadcast. Along with an overall overview of the architecture, characteristics, and applications of vehicular networks, the authors discuss the challenging issues in the research on performance improvement for safety applications, and provide a comprehensive review of the research literature.A cross layer broadcast protocol is included to support efficient safety message broadcast by jointly considering geographical location, physical-layer channel condition, and moving velocity of vehicles in the highway scenario. To further support multi-hop safety message broadcast in a complex road layout, the authors propose an urban multi-hop broadcast protocol that utilizes a novel forwarding node selection scheme. Additionally, a busy tone based medium access control scheme is designed to provide strict priority to safety applications in vehicle-to-infrastructure communications.This book offers useful insights into protocol design and inspires a new line of thinking in performance improvements for safety applications in vehicular networks. It is a valuable resource for professionals, researchers, or advanced-level students working in vehicular networks or quality of service.

Download and read online ebook Design of a Privacy-aware Routing Protocol for Vehicular Ad Hoc Networks write by Adrien Daunou. This book was released on 2012. Design of a Privacy-aware Routing Protocol for Vehicular Ad Hoc Networks available in PDF, EPUB and Kindle. English: the continued growth of the vehicular fleet has opened new business opportunities and new needs of road safety. The constant mobility of individuals and the necessity of staying connected makes studying the possibilities of connectivity and transmission of information between vehicles one of the main objectives of the cars manufacturers. The social costs that accompany this development -increase in accidents, congestion of cities, etc.- increases the needing of improving car safety by providing information on road traffic conditions and also making interesting the study of VANETs (vehicular ad hoc networks) by the authorities and the administration. Anonymity is a key concern in this kind of network, guaranty that the identity of a message sender is protected is an important challenge and might be a mandatory feature for some VANET applications. For this purpose, we introduce Crowd, an anonymity protocol that provides a mechanism for anonymous Web browsing. The main idea behind Crowd anonymity protocol is to hide each user's communications by routing them randomly within a group of similar users. Consequently by using the Crowd protocol neither the receiver nor a corrupt group member or local eavesdropper that observes a message being sent by a particular user can never be sure whether the user is the actual sender, or is simply routing another user's message. The main objective of this PFM is to design and implement an anonymity solution based on the Crowd anonymity protocol to work in a VANET environment, and later on to evaluate QoS and Privacy metrics under this condition. Such evaluation is done by implementing realistic vehicular network scenarios with the network simulator NCTUns and perform different simulations for making a performance evaluation, analyzing packet lost, end-to-end delay and the throughput as a function of the Crowd protocol parameters.
