This paper is faced with group sensing problem, where HD map producers motivate private cars to collect data from real world. Group sensing needs vehicles to communicate physically, and drivers to collaborate strategically. First we consider communication module, three VANET-based methods are proposed to achieve inter-vehicle message relaying. Secondly, we consider collaboration module which motivates...
Vehicular ad-hoc networks (VANET) have gained importance in recent years due to urbanization and technical advancements. Vehicle to vehicle (V to V) and Vehicle to infrastructure (V to I) are important types of VANET which have been exploited to their optimum use for the comfort and safety of the people on roads and off roads. With the several other features of VANET which are already being implemented...
Many routing algorithms for vehicular ad-hoc networks have relied on geographic forwarding as a means to reduce the paths' sensitivity to individual vehicle movements. In recent years, the basic forwarding strategies have been refined to create road-based paths, connecting successive road intersections selected on the basis of the connectivity between them. Revisiting this idea, we present two different...
Vehicular ad-hoc networks (VANETs) have gained a lot of attention from both academic and industry due to its immense potential in revolutionizing the vehicular communication industry. VANETs facilitate vehicles to share safety and non-safety information through messages. Safety information includes road accidents, natural hazards, road blocks etc. Non-safety information includes tolling information,...
Platooning is an important mechanism to increase the capacity of roads and the efficiency of driving. Vehicular ad hoc networks (VANETs) can enhance the performance of platoons. In this paper, a novel mechanism that selects a leader vehicle autonomously for a platoon based on relative mobility information of vehicles is proposed for overcoming the restriction on vehicles and for facilitating platoons...
In this study, we propose a variation of the RAdNet for vehicular environments (RAdNet-VE). The proposed scheme extends the message header, mechanism for registering interest, and message forwarding mechanism of RAdNet. Based on results obtained from simulation experiments, we compare the performance of RAdNet-VE against that of RAdNet, a basic content-centric network (CCN) using reactive data routing,...
The paper presents a solution for reducing road traffic emissions and particulate matter from non-electric (classic) vehicles in cities by sharing cooperative driving information. Vehicles are equipped with dynamics and GPS sensors. Ad-hoc vehicular networking (VANET) is used as media for communication. A specific algorithm is developed to collect anonymous information and suggest to drivers best...
Conceiving a smart city is coming to maturity, to make less the problems produced by the swift urbanization. It mainly focuses on how to increase the quality and comfort of citizens by using information and communication technologies. That being said, make smart cities will offer a flamboyant metamorphosis for the success of cities' development, they propose a way adapted to the multitude of urban...
The paper proposes a method to make roads a safer place for driving by taking advantage of Internet of Things (IoT) enabled vehicles. The proposed method is based on assessing the trust levels of each vehicle and the behavioral patterns of the driver. Proposed method also utilizes a mobile agent(MA) which would help detecting Misbehaving nodes in the IoT enabled Vehicular Adhoc NETwork (VANET). The...
The Smart cities are a relevant topic nowadays. It attracts most researchers and governmental authorities, due to the vision to adopt technology information and communication in this context, to facilitate access to urban services. Security stills a permanent challenge that affects most smart cities applications. Vehicular Ad Hoc Networks (VANets) is one of those applications, classified in the smart...
VANET (Vehicular Ad hoc Network) is a special kind of ad hoc network in which each vehicle is regarded as a communication unit, which has attracted lots of attention in recent years. Vehicle's movement is restricted by road and environment in VANET, while traditional random mobility model and way-point mobility model can't reflect the realistic vehicle traces. How to evaluate wireless routing protocol...
In this study an Overtake Mishap preventive road safety system is designed. The System makes driver aware about the platoon of which its vehicle is a part. The system helps driver to know the overtaking behavior of back vehicle. The system with the help of front vehicle's response also guides driver when it decides to overtake it. The Road-Side-Devices help to maintain the communication amongst vehicles...
For VANET safety services a context aware system for the Automatic Crash Notification (ACN) is developed while the context aware Congested Road Notification system (CRN) is developed for the convenience services. A simple fuzzy logic model is proposed and compared to different severity estimation models deployed for both systems. The performance of the ACN models is compared using a test collection...
In the future, VANET and IEEE 802.11p will play important role in ITS with many applications that improve the quality of traffic. Road environment is one of factors that influences the performance of the wireless communication. Especially for blind corner, the buildings which obstruct the signal may be a big challenge for the data transmission of safety applications. Thus, the performance analysis...
Vehicle Ad hoc Network (VANET) is an emerging technology and a new application of mobile Ad Hoc technology in the field of traffic. As the simulation experiments cost less manpower and material resources and they are easy to reproduce the same scenario, VANET simulation technology has become a focus of scholars. But node mobility is strictly limited in the realistic traffic environment and fast moving...
Understanding vehicle mobility is essential for devising successful protocols for vehicular communications. Vehicles move at varying speeds on roads whose complexities range from plain highway lanes to urban boulevards with intersections/circles, traffic lights and various points of interest on them. This mobility pattern combined with vehicle density fluctuations depending on location and time makes...
Traffic congestion is one of the serious problems in all the mega-cities. It is evolving with rapid growth of population. To overcome the challenge, this study proposes an intelligent system that can optimize the road traffic in real-time without having a huge infrastructural change by using vehicular ad-hoc network (VANET), and the swarm intelligence of natural environmental agent called ant colony...
Vehicular communication technology leverages communication equipment and infrastructure to improve road safety and provide useful services for road user.
