This book was released on 2014-09-10 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Position-based routing was originally developed for packet radio networks in the 1980s [6]. It received renewed interest during the last few years as a method for routing in mobile wireless ad hoc and sensor networks [1, 2, 4]. The general idea of is to select the next hop based on position information such that the packet is forwarded in the geographical direction of the destination. Position-based routing can be divided into two main components: the location service and position-based forwarding. The location service [5, 13] is used for mapping the unique identifier (for example an IP address) of a node to its geographical position. In mobile ad hoc networks, providing accurate location service for position based routing, with low communication overhead, appears to be more difficult task than routing itself [13]. In case of sensor networks, however, destination is a sink or base station whose position is made available to source sensors by flooding. Position-based forwarding is performed by a node to select one of its neighbors as the next hop the packet should be forwarded to. Usually, the following information is required for the forwarding decision: the node's own geographical position, the position of all neighbors within transmission range and the position of the destination. Based on this information, the forwarding node selects one of its neighbors as the next hop such that the packet makes progress toward the geographical position of the destination.

Book excerpt: Location-based services have been identified as a promising communication paradigm in highly mobile and dynamic vehicular networks. However, existing mobile ad hoc networking cannot be directly applied to vehicular networking due to differences in traffic conditions, mobility models and network topologies. On the other hand, hybrid architectures in vehicular networks, with ad hoc-based inter-vehicle and infrastructure-based vehicle-to-roadside communications, can facilitate robust and efficient communication services using geographical information. In this dissertation, we focus on the design and evaluation of location-based protocols and algorithms to improve scalability, efficiency, and resiliency in hybrid vehicular networks. We first provide a cross-layer self-localization algorithm for moving vehicles. A new ultra-wide band (UWB) coding method, based on an orthogonal variable spreading factor and time hopping, is proposed for minimum interference during ranging. Then, a UWB based non-metric multidimensional scaling derives accurate and robust self-localization results. In addition, we employ an online compressive sensing scheme to count and localize sparse roadside units (RSUs) for war-driving applications. Online war-driving records received signal strength (RSS) values at runtime, and can recover the number and location of RSUs immediately based on far fewer noisy RSS readings. After obtaining the location information of vehicles and RSUs, we address multiple channel scheduling in hybrid vehicular networks. We use the natural beauty of Latin squares to achieve fair and deterministic scheduling in micro-time scale for channel access and macro-time scale for channel assignment. A grid based scalable scheme is proposed to map Latin squares to grids for dynamic single-radio multi-channel scheduling. Another interference graph based scheme uses nodal location and social centrality to reflect the social behavior patterns related to access in vehicular networks, and then form adaptive clusters for multi-radio multi-channel scheduling. We also investigate several vehicular environments, and propose corresponding location- and environment-aware data dissemination solutions. We first present an efficient on-demand bounce routing method in vehicular tunnels. It applies a hybrid signal propagation model and location-based forwarding metric to choose the best data dissemination strategy. Then, we design a hybrid routing scheme for robust and reliable data dissemination in urban transportation environments, in which the choice of communication method is dependent upon geographical connectivity, by taking network coding based multicast routing in dense network and opportunistic routing using carry and forward method in sparse network. In addition, we propose an online learning based knowledge dissemination in unmanned aerial vehicle (UAV) swarms under delay/disruption-tolerant networking, where each UAV adaptively chooses broadcast probability by learning link status. A fractionated Cyber-Physical System framework, based on partial ordering for knowledge sharing and colored Petri net for work flow, is implemented to achieve distributed knowledge management in UAV swarms. Our extensive simulation and real testbed results show the robustness and efficiency of location-based services in vehicular networks with hybrid architectures.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: [ANGLÈS] VANETs (Vehicular Ad-hoc Networks) are an emerging new technology which integrates the capabilities of new generation wireless networks to vehicles. It includes a variety of applications such as co-operative traffic monitoring, control of traffic flows, blind crossing, prevention of collisions, nearby information services and real-time detour routes computation. Another important application for VANETs is providing Internet connectivity to vehicular nodes while on the move, so that passengers can download music, send emails, book a restaurant or play games. Because of the high nodes mobility and unreliable channel conditions, VANETs have unique characteristics which pose many challenging research issues. This work is mainly focused on a key networking problem: routing protocol for VANETs. The main requirement of routing protocols is to achieve minimal communication time with minimum consumption of network resources. Many routing protocols have been developed for MANETs (Mobile Ad-hoc Networks), such as AODV (Ad-hoc On demand Distance Vector) and DSR (Dynamic Source Routing). However, VANETs differ from MANETs by their highly dynamic topology. A number of studies have been done to simulate and compare the performance of those routing protocols in various traffic conditions in VANETs. Simulation results showed that MANET routing protocols suffer from poor performances because of the characteristics of fast vehicle's movement, dynamic information exchange and relative high speed of mobile nodes. This text aims to continue the work of Roger Calzada in his final degree thesis. In that thesis, AODV was the routing protocol used during the simulation process to evaluate its performance over VANETs. The conclusion of the thesis was that AODV is not the best routing protocol to handle high mobility of nodes and short duration of routes. He proposed as future work the evaluation of existing routing protocol which considers car position, trajectories or speeds gathered via GPS (Global Positioning System) that could lead to better results. To consider the vehicle network, people can intuitively think to use the geographical position information to decide the route. Most position based routing algorithms base forwarding decision on location information. GSR (Geographical Source Routing) is a promising routing technique for VANETs and recently several routing protocols have been proposed based on it. For example, GPSR (Greedy Perimeter Stateless Routing) is one of the best known position-based protocols in literature. Basically, our project is divided in two parts: first, we make a state of the art related to the VANETs in order to find the most appropriate and recommended mobility generator and network simulator reported in literature. We also include at the end of this part the description of GPSR routing protocol. Second, from the research done in the previous part, we use VanetMobiSim as a mobility generator due to its variety models that could be tested; and NS2 as a network simulator for being one of the most used by many authors and also due to its compatibility with VanetMobiSim. Using these tools, VanetMobiSim and NS2, we carry out a performance evaluation of two routing protocols (AODV and GPSR) over VANETs. We give different values to parameters such as the number of nodes, speed, transmission range and different propagation models. Finally, we analyze and discuss the benefits of GPSR compared to AODV in vehicular scenarios.
