In recent years, Vehicle Ad Hoc Networks (VANETs) have become very popular. A typical VANET defines an intelligent way of using vehicular networking by integrating vehicular connections via a number of short-distance ad-hoc networking links, such as the IEEE802.11p. This type of system could provide effective communication between moving vehicles and fixed Road Side Units (RSUs), which are usually very expensive to install and may, in some cases, undergo heavy demand. To improve the efficiency of communication between vehicles and RSUs (Vehicle to Infrastructure, V2I), most existing work ignores the following facts: the uneven distribution of vehicles and unbalanced working loads on different RSUs. By considering the periodic and the unchanging features of public transportation, we propose a novel V2I hybrid optimisation scheme named Dynamic Resources Allocation Scheme (DRAS). In this scheme, all resources on the RSUs are scheduled as a whole and buses will be introduced as moving infrastructure points (or relay stations) to take some of the burden of the RSUs in real-time traffic conditions. We import the Variable-Length Contention Free Period (VL-CFP) for MAC access and also define Time-to-Live (TTL) value to guarantee the data credibility on bus. Using both Math analysis and NS-2 simulation, we can prove our DRAS can achieve a better QoS performance and adequate utilisation of RSU resources than legacy 802.11p and WAVE-based HCCA. These advantages become more obvious as the vehicles number increases.
近年来，车载自组织网络(vanet)变得非常流行。典型的VANET定义了一种使用车载网络的智能方式，通过许多短距离自组织网络链路(如IEEE802.11p)集成车辆连接。这种类型的系统可以在移动车辆和固定的路旁单元(rsu)之间提供有效的通信，这些装置通常安装非常昂贵，在某些情况下可能会有很大的需求。为了提高车辆与rsu之间的通信效率(Vehicle To Infrastructure, V2I)，大多数现有工作忽略了以下事实:车辆分布不均匀，不同rsu上的工作负载不平衡。考虑到公共交通的周期性和不变性特点，提出了一种新的V2I混合优化方案——动态资源分配方案(DRAS)。在这个方案中，所有的rsu上的资源作为一个整体进行调度，公交车将被引入作为移动的基础设施点(或中继站)，以在实时交通情况下承担rsu的一些负担。我们引入了可变长度争用自由周期(VL-CFP)用于MAC访问，并定义了生存时间(TTL)值以保证总线上数据的可信度。通过数学分析和NS-2仿真，我们可以证明我们的DRAS可以实现比传统802.11p和基于wave的HCCA更好的QoS性能和充分利用RSU资源。随着车辆数量的增加，这些优势变得更加明显。

In recent years, Vehicular Ad-hoc NETworks (VANETs) have experienced an intense development, driven by academia, industry, and public authorities. On the basis of this, it is reasonable to expect that VANETs will finally hit the market in the near future. In order to reach commercial success, VANETs must effectively operate also during the first years of deployment, when the market penetration rate will be unavoidably low and, consequently, only a small number of suitably equipped vehicles (VANET-enabled) will be present in the roads. Among the possible strategies to face the initial sparse VANET scenarios, the deployment of an auxiliary network constituted by fixed Road Side Units (RSUs), either Dissemination Points (DPs) or relays, is certainly a promising one. In order to maximize the benefits offered by this support infrastructure, the placement of RSUs needs to be carefully studied. In this work, we analyze, by means of numerical simulations, the performance of an application that leverages on a finite number of DPs for disseminating information to the transiting vehicles. The positions of the DPs are determined through a recently proposed family of optimal placement algorithms, on the basis of properly generated (through simulations) vehicular mobility traces. The analysis is carried out considering two realistic urban scenarios. In both cases, the performance improvement brought by the use of multi-hop broadcast protocols, with respect to classical single-hop communications with DPs, is investigated.

The Software Defined Radio (SDR) is a technology that enables to run several radio waveforms on the same hardware terminal. In this paper, we evaluate the benefits of using several communication technologies, based on SDR hardware, in automotive cooperative systems. We propose to integrate to the vehicles a SDR hardware supporting IEEE 802.11 and DVB-T technologies. We study the behaviors of cooperative systems in a realistic environment. We investigate, based on simulation experiments, the performances of applications integrated in the cooperative system when this system is based on multiple wireless technologies.

This paper proposes a new adaptive modulation (AM) scheme for closed-loop MIMO transmission over wireless correlated channels. Two correlation-based channel models are considered to illustrate the interest of the proposed solution in realistic environments representative of transportation systems. Several simulation results for different transmission scenarios are presented and discussed. It is shown that the proposed AM approach outperforms several precoding schemes and provides full diversity order.

Vehicular traffic congestion in metropolitan cities during disaster is a challenge which presents dire consequences for transporting VIPs, life saving drugs, patients, accident victims in need of immediate medical assistance etc. With better navigation system and real-time traffic congestion updates, the vehicles can overcome delays. Vehicular Ad Hoc Network (VANETs), transmits the real time congestion information to the vehicles from a centralized database to avoid unexpected congestion and follow the shortest path to the destination. In this paper a proposed prototype which can be modified to work for the requirement with different models, such as general traffic prediction and re-routing during emergencies in case of fire, accidents etc. along the route is worked out. IEEE 802.11p which has been introduced exclusively for vehicular environments has been implemented at the Physical and Medium Access Control(MAC) layers of the WAVE protocol stack which was considered for a metropolitan city over an unpredictable high density of vehicles. Evaluation of the performance of IEEE 802.11p, Wireless Access for Vehicular Environment (WAVE) communication standard against IEEE802.11a for the vehicular environment for multiple scenarios has been simulated and the results are encouraging.
灾害期间大城市的车辆交通拥堵是一个挑战，它对运送贵宾、救生药品、病人、需要立即医疗援助的事故受害者等带来了可怕的后果。有了更好的导航系统和实时交通拥堵更新，这些车辆可以克服延误。车辆自组织网络(Vehicular Ad Hoc Network, VANETs)从一个集中的数据库向车辆传输实时的拥堵信息，以避免意外的拥堵，并沿着最短的路径到达目的地。本文提出了一种可修改的原型，该原型可适应不同模型的要求，如一般交通预测和沿线发生火灾、事故等突发事件时的改道。专为车辆环境引入的IEEE 802.11p已在WAVE协议栈的物理和介质访问控制(MAC)层实现，该协议被认为适用于不可预测的高密度车辆的大都市。对IEEE802.11a和ieee802.11 p车载环境无线接入(WAVE)通信标准在多种场景下的性能进行了仿真评估，结果令人鼓舞。

In this work, we provide an overview of an innovative approach for effective cross-network information dissemination, with applications to Vehicular Ad-hoc Networks (VANETs). In particular, we describe the main approach followed in an on-going bilateral Italy-Israel project (“Cross-Network Effective Traffic Alert Dissemination,” X-NETAD). The X-NETAD project leverages on the spontaneous formation of WiFi local VANETs, with direct connections between neighboring vehicles, in order to disseminate, very quickly and inexpensively, traffic alerts received from the UMTS network.

In this paper, we propose a subgradient optimization method for pedestrian localization based on received signal strength in wireless network. The objective function of weighted least-squares estimation is adopted, which shows good convexity and has immunity to shadowing effect. We also approximate the subgradient of the objective function by a recursive form so that it can be implemented in a decentralized manner within each sensing node. A variable step size is proposed to take into consideration both the subgradient and minimum adjustment to accelerate convergence. Furthermore, the convergence analysis is also given to show the feasibility of our design for the step size. From simulation results, we can see the proposed algorithm has better accuracy and convergence rate than the conventional decentralized algorithms to localize a stationary or moving target in wireless network.

In most cases indoor local positioning algorithms are not effective enough. RSS-based methods are very sensitive to variations in physical environment dependent on relative positions of furniture, doors, human bodies, etc. The results of ToF-based ranging in closed areas always include additional NLOS-component. A method of combination of both RSS and ToF approaches is described. Results of conducted indoor experiments confirmed that the accuracy of position calculation significantly increased.

In the near future vehicular networks (VANETs) based on wireless technology will be part of our daily lives. VANETs enable vehicles that are not necessarily within the same transmission range to communicate with each other. They also allow vehicles to connect to Roadside Units (RSUs), which are connected to the Internet, forming a backbone mesh that offers the capability of communicating with each other and with roaming vehicles. In this paper, we exploit the RSU network to efficiently route packets between far away vehicles in the VANET. We evaluate our system using ns2 simulation, and compare it to existing solutions. The results demonstrate the feasibility and efficiency of our proposed scheme in terms of query delay, packet delivery ratio, and generated traffic.
