Extensive researches are being carried out to implement on-demand, QoS supported VANET routing algorithms. Reliability and timely information delivery are of high concern in VANETs. Providing optimal QoS over specific period of time with varying number of nodes (vehicles) is highly challenging the VANET research groups. This paper addresses the importance of providing optimal QoS for multimedia applications in VANET. Research work carried out and presented in this paper proposes a receiver based routing algorithm for achieving Optimal QoS for highly dynamic Vehicular Ad hoc Network (QVANO). The metrics used to achieve optimal QoS is delay, packet loss and bandwidth. The proposed algorithm is compared with AODV. Simulation test runs are generated using NS-2. Several test beds were configured to analyse the performance of the proposed algorithm.

This paper describes WAVE (Wireless Access in Vehicle Environment) system design especially for Urban area. WAVE technology is currently is developing in worldwide and there are standardizations under IEEE, ETSI (European Telecommunication Standard Institutes), and ARIB (Association of Radio Institutes and Business) in Japan. WAVE technology is based on wireless LAN (Local Area Network) technology in IEEE802.11 series and it is studied as IEEE802.11p. The frequency band is assigned in 5.9GHz in Europe and north America. In Japan, there are 5.8GHz and next 700MHz plan. In general WAVE radio range is not so much long distance such as mobile phone but achieves high speed access network in dedicated short distance, therefore it is also called DSRC (Dedicated Short Range Communications). Therefore authors describe how to use WAVE and mobile communication architecture for vehicular wireless communications, especially in urban area.
本文介绍了面向城市的车载无线接入(WAVE)系统的设计。WAVE技术目前正在全球范围内发展,并在IEEE, ETSI(欧洲电信标准协会)和ARIB(日本无线电研究所和商业协会)下有标准化。WAVE技术是基于IEEE802.11系列中的无线局域网技术,并作为IEEE802.11p进行研究。在欧洲和北美,频段被指定为5.9GHz。在日本,有5.8GHz和下一个700MHz的计划。一般来说,WAVE无线电的范围不像移动电话那么远,而是在专用短距离内实现高速接入网络,因此也被称为DSRC (dedicated short range Communications)。因此,作者描述了如何利用WAVE和移动通信体系结构实现车载无线通信,特别是在城市区域。

Delays and traffic bottlenecks represent a significant economic loss and inconvenient issues in transportation of persons and goods. That is, transportation systems still have a wide spectrum of issues that need to be addressed. In this sense, Intelligent Transportation Systems (ITS) are expected to provide an efficient and modern way to deal with these issues. Nevertheless, underlying technologies are not always reachable for urban settlements with budget restraint such as in rural areas and in developing countries. In this paper, we present a novel and affordable architecture aiming to improve vehicular traffic management based on intelligent Virtual Police Agents (VPA). Our architecture is inspired from real police agents figure which are oriented to manage traffic issues efficiently. The replication of basic features of police agent role in VPA results in collaborative and hierarchical agent-based relationship architecture. This framework aims to establish system-optimal based in traffic flow equilibrium with maximum-flow and minimum-cost.

In this paper, we analyze the operational UMTS handover logs. The analysis result shows UMTS handover logs possessing more severe cell oscillation phenomenon compared to GSM. To eliminate the effect of cell oscillation phenomenon, we propose an approach to estimate the traffic state using UMTS handover logs. An experiment on a 12km road segment of Sun Yat-sen Freeway in Taiwan was conducted to verify the feasibility of our proposed approach. The experiment showed that every time a slowdown happened, a speed decreasing could be detected. Also, the estimation differences between the proposed approach and fix vehicle detection (VD) systems were less than 20kmph (km per hour) in 76% of the measurements, which proves that UMTS handover logs qualifies for traffic state estimation.

In this work we have proposed a parking management framework that monitors vehicles driving in and out, calculates the number of available parking spaces, and finally disseminates the information to the parking's customers. For monitoring vehicles, we show our implementation of magnetic sensor network. The magnetic sensor is capable of collecting number of vehicle passing over the sensor, estimating vehicle's speed and length. The data is communicated over wired or wireless links to the server and is stored in the database for analysis and the number of available parking spaces can be displayed for customers before entering the parking garage. The dissemination of the information collected is through social network such as Twitter and Facebook. The test results show that the system yields a very accurate vehicle counting. The data obtained are consistent with the characteristics of drivers who access the parking facility. Analysis of data collected with our system is shown to provide useful information on which our future prediction of parking spaces will be based.

Dating back to late 1960s, ITS has achieved a rapid development, in which US, Japan, Canada, Germany, France and other countries throughout the world invested lots of founds and human resources. After a long time study, these countries tended to use high-tech to transform the existing road traffic and management system, which has greatly improved the quality of road network capacity and service. The implementation of these programs instead of relying mainly on the construction of more roads to meet the growing traffic demand has already aroused general concern. ITS, as a new attempt on the improvement of traffic congestion, is focusing on releasing dynamic transportation information to public, reporting traffic dynamics and guiding in travel. Facts prove that ITS may be the best way to solve the urban traffic congestion and improve traffic safety and efficiency. And this paper is trying to explore the intelligent technology working in dynamic traffic information collection, processing, analysis and dissemination of this system.

Vehicular Ad-hoc NETworks (VANETs) are witnessing an ever increasing interest. Security is a key aspect to pave the road to commercial deployments, as malicious attacks may increase the risk of accidents. Key management in VANETs poses further problems, as connectivity is limited and communication with a central certification authority might be problematic. In this paper, we propose a novel approach to key management for securing VANET communications. In particular, a general framework for key group multicast is proposed, with specific application to a VANET communication scenario.

With the term infomobility we refer to the broad range of Intelligent Transport Systems (ITS) information services. Despite the increasing efforts on development of infomobility services, it is recognized that they still show significant limitations in providing end users with reliable and seamless information. In this paper we argue that a systemic approach is needed to foster the growth of novel solutions for the delivery of integrated realtime and always-on infomobility services, to be seamlessly provided across different transport operators, modes and geographical areas. The proposed approach — conceived and implemented within the ongoing SIMob research project in Tuscany Region (Italy) — relies on the definition of an “Open Working Environment”, i.e. a socio-technical environment whose objective is to facilitate the co-operation of stakeholders to foster the growth of an integrated infomobility system at regional scale. Its main constituents are: a Cooperative Network of stakeholders, including regional and national subjects from Public Administrations, Enterprises and Research Bodies; an Architectural Framework, providing the reference technological baseline enabling the rapid configuration and deployment of different technological capabilities.

Vehicular networks often consist of computational devices that collect data representing the external environment (e.g., road traffic volume, terrain conditions, and vehicle tracking). The data collected is prone to errors for two reasons: first, the processing algorithms in devices often have only limited capabilities that result in a fuzzy and imprecise representation of the external datum; second, some of the devices may be maliciously faulty mis-reporting the external datum. In such a setting, replicating the devices and voting on the environment data collected by them enhances the trust-worthiness of data reported to the application. The paper describes a cooperation mechanism that embodies two complementary functions: replication of devices and voting among devices. Device-level cooperation is realized using a tree-structured overlay set up over a vehicular network, in which the root node is attached to a data dissemination station and the leaf nodes are attached to the data collection devices in different geographic regions. Voting among the data collected is carried out at the leaf nodes whereupon a sanitized data propagates up the tree towards the root. An intermediate node may also carry out aggregation functions on the data arriving from its downstream tree segments and then forward the aggregated data upstream. The paper describes the voting-based data collection and dissemination as a middleware service.

The paper discusses the infusion of context awareness in the management of data quality in a replicated sensor based data collection network. Given a 2-phase voting protocol to decide on data delivery from sensors to the end-user, the paper discusses the impact of environment parameters (such as fault severity and network message loss) and resource parameters (such as network bandwidth and number of replicas) on the quality of user-level data delivery. The degree of control is determined by the contextual inputs that capture the dynamically changing scope and importance of data to the application.
