With today’s rapidly improving link-layer technology, and the widespread adoption of wireless networking, the creation of large-scale ad hoc networks could be construed as all but inevitable. However, for routing in a network to be feasible, there is a pressing need for a scalable ad hoc routing protocol. Applications for large-scale ad hoc networking include consumer owned networks, tactical m...

Vehicular ad-hoc networks are a prospective technology which contribute to safer and more efficient roads. Inter-vehicle communication provides drivers and concerned authorities with information about road conditions, supports the coordination in case of emergency and improves traffic management. Furthermore, vehicular ad-hoc networks offer information and entertainment services to mobile users...

In vehicular ad hoc networks there is the ability to communicate between vehicles. This Communication which is wireless should be rapid and reliable. These networks have unique characteristic. This communication among vehicles has many advantages in safety and comfort applications. Since, the roads are always encountered to accidents and risks, using optimized tools could be useful in these sit...

The vehicular ad hoc network (VANET) is an emerging new technology. Developing multi-hop routing protocols for urban VANETs is a challenging task. VANETs are a kind of Wireless ad hoc network that usually has a routable networking environment on top of a Link Layer ad hoc network. In this paper, we first analyze the unique features of urban VANET and then we move on to discuss the various VANET...

The era of Internet of Things (IoT) has begun to evolve and with this the devices around 8 us are getting more and more connected. Vehicular Ad-hoc NETworks (VANETs) is one of the 9 applications of IoT. VANET allow vehicles within these networks to communicate effectively with 10 each another. VANETs can provide an extensive range of applications that support and enhance 11 passenger safety and...

Security is an important issue in ad hoc networks, especially fo r security sensitive applicat ions. This paper main ly focus the authentication based on the group signature for providing the security and privacy in vehicular ad hoc networks (VANET). In VANETs, g roup signature is widely used for vehicles to achieve unauthenticated vehicles. A group signature scheme allows members of a group to...
