Modern vehicles are equipped with numerous driver assistance and telematics functions, such as Turn-by-Turn navigation. Most of these systems rely on precise positioning of the vehicle. While Global Navigation Satellite Systems (GNSS) are available outdoors, these systems fail in indoor environments such as a car-park or a tunnel. Alternatively, the vehicle can localize itself with landmark-based...
Vehicular Ad Hoc Networks (VANETs) is a form of mobile ad hoc network (MANETs)-where frequent changes in wireless network topology happen due to high mobility of vehicles. Routing of data packets in such highly mobile, multi hopped and without dedicated infrastructure environment is a big research challenges which need to be addressed by existing/proposing new solutions. In the past few years, a lot...
VANET are self-configuring networks composed of a collection of vehicles and elements of roadside structure linked with each other without requiring any infrastructure, sending and receiving information of current traffic situation. These are used for the communication among the mobile vehicles. It has some security issues like attacks, authentication etc. In this paper, we have discussed various...
Vehicular Ad Hoc Network (VANET) is a subgroup of mobile ad hoc network (MANET). It is an emerging new technology to exchange information between vehicles to vehicles. VANETs are considered as one of the most noticeable technologies for improving the efficiency and safety of transportation systems. VANET mainly used to exchange traffic information between the vehicles and prevent accident. In VANETs...
Weproposed a Position Prediction based Multicast Routing (PPMR) for VANET with the objectives of alleviating the broadcast storm problem of multicast tree discovery and simultaneously minimizing the number of forwarding vehicles. A unicast protocol, Position Prediction based Unicast Routing (PPUR) serving as a base for our multicast protocol is also proposed. With the help of Global Positioning System...
This research addresses the problem of navigating a robotic vehicle autonomously on unstructured roads where road information is not accurate. A real-time system for finding and tracking unstructured road in off-road conditions is proposed. The subsystems of autonomous navigation — road detection, steering, and obstacle avoidance are discussed in detail. This method has been integrated into a vehicle...
Much research is being carried out in autonomous driving of vehicles under various disciplines but very few autonomous navigating vehicles are developed till date. This paper presents a novel technique, with a practical example, for the representation of navigational information under real-time considerations. Machine learning algorithms can easily be trained with the data sets developed from the...
Timely detection of other vehicles in the vicinity is of extreme importance to help avoid accidents and potential loss of human life, traffic jams especially in Hilly areas with hair pins bends and reduced visibility condition in dense foggy areas. This paper introduces a GPS based system which actively and continuously sends vehicle location coordinates (latitude/longitude) to the eye in the sky...
By means of recent advancements in the wireless networking area a totally new paradigm came into existence in the domain of wireless communication well known as Vehicular Ad-Hoc Network (VANET) employed specially for providing road safety, comfort and convenience to the driver as well as passengers during their journey. A VANET is a type of highly dynamic wireless network that can be formed without...
This paper presents an intelligent traffic management system using RFID technology. The system is capable of providing practically important traffic data which would aid in reducing the travel time for the users. Also, it can be used for other purposes like tracing of stolen cars, vehicles that evade traffic signals/tickets, toll collection or vehicle taxes etc. The system consists of a passive tag,...
The present work is related to an electrically driven magnetostrictive brake for use in brake system of the vehicles, more particularly design of magnetostrictive actuator for moving friction pads in disc brake back and forth thus, capable of readily accomplishing intelligent braking functions similar to that achieved using antilock braking system. The detail of the mechanical and magnetic circuit...
