today, one of the new technologies in the modern era is vehicular ad-hoc network which has takenenormous attention in the recent years. because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called v2v orvehicle to vehicle communication and vehicle to roadside infrastructure, called v2i. designin...

Vehicular ad hoc networks (VANETs) are vulnerable to many kinds of security attacks, so it is necessary design an authenticated key agreement (AKA) scheme for securing communication channels in VANETs. Existing AKA schemes VANETs have not provided efficient and secure method V2V V2I communications simultaneously while meeting the privacy requirements. Further, few updating mechanisms, which sec...

The advances in wireless communication techniques, mobile cloud computing, automotive and intelligent terminal technology are driving the evolution of vehicle ad hoc networks into the Internet of Vehicles (IoV) paradigm. This leads to a change in the vehicle routing problem from a calculation based on static data towards real-time traffic prediction. In this paper, we first address the taxonomy...

Content dissemination over vehicular networks is a critical challenge due to its high intermittent connectivity. However, content cache and retrieval by exploiting the information-centric networking (ICN) paradigm did not get much attention. In this paper, in order to improve the efficiency of content retrieval, we propose a novel popularity-aware content caching and retrieving strategy in VANE...

Cooperative ITS is enabling vehicles to communicate with the infrastructure and each other, to provide improvements in traffic safety, traffic control, and traffic management. Researchers from fields of information technology, communication, and traffic engineering are involved in the development of applications to achieve these goals. One challenge is the testing of such systems and their impa...

Global Positioning System (GPS) is widely used for finding the shortest path from source to destination based on a local map database, as real-time road situations are not taken into consideration in GPS. Vehicular ad-hoc network (VANET) based navigation system automatically searches for the route that yields minimum traveling delay. The system uses collected data to provide navigation service ...

Traffic congestion is a large and growing problem in many countries due to an ever increasing number of vehicles. Increasing capacity by simply extending the road infrastructure is in many places impossible due to space and cost limitations. Everyday, people spend countless hours in car queues all over the world. The existing road infrastructure must be better utilized to save time and to reduc...

In recent years, intelligent transportation systems (ITS) applications e.g. active traffic management, safety application, etc. are gaining popularity. Again internet-based services are also emerging nowadays in vehicular communication networks. Therefore, a suitable routing mechanism is essential to support delay tolerant networking to ensure reliable information exchange. On the other hand, g...
