Multimedia transactions between vehicles are expected to become a promising application in VANETs but security is a fundamental issue that must be resolved before such transactions can become practical and trusted. Existing certificate-based digital signature schemes are ineffective for ensuring the security of multimedia transactions in VANETs. This ineffectiveness exists because there is no g...

In intelligent transportation systems, the cooperation between vehicles and the road side units is essential to bring these systems to fruition. Vehicular ad hoc networks (VANETs) are a promising technology to enable the communications among vehicles on one hand and between vehicles and road side units on the other hand. However, it is a challenging task to develop a reliable routing algorithm ...

Vehicular Ad hoc Networks (VANETs) allow vehicles to form a self-organized network without any fixed infrastructure. VANETs have received wide attention and numerous research issues have been identified in the recent time. The design and implementation of efficient and scalable routing protocols for VANETs is a challenging task due to high dynamics and mobility constraints. In this paper, we ha...

Vehicular Ad-hoc Networks (VANETs) are one of typical application of wireless communication technology, which provide communications among nearby vehicles and between vehicles and roadside units (RSUs) connected the infrastructure. VANETs provide a perfect way to collect dynamic traffic information and sense various physical conditions related to traffic distribution with very low cost and high...

This paper initiates the study of scaling laws for vehicular ad hoc networks (VANET)s. It provides a general framework to study VANETs. The fundamental capacity limits of these networks are investigated and we show how the road geometry affects this capacity. The VANET capacity is calculated for different road structures. The need for new capacity metrics is discussed. These results are obtaine...

Vehicular Ad hoc Networks (VANETs) are becoming a reality where secure communication is a prerequisite. Public key infrastructure (PKI) can be used to secure VANETs where an onboard tamper proof device (TPD) stores a number of encryption keys which are renewed upon visiting a certificate authority (CA). We previously proposed a dynamic key distribution protocol for PKI-based VANETs [1] to reduc...

Vehicular Ad-Hoc Network (VANETs) provides the vehicle to vehicle (V2V) communication for the safety application. There are many security requirements in VANETs. ECDSA algorithm fulfils all the security requirements but it’s come with the processing overhead and there is a chance of computation based DoS attack. However the VANETs are the time constrained each safety message should be reached a...

Vehicular ad hoc networks (VANETs) have emerged as a prominent technology that facilitates the exciting research and application area for current era of vehicular system. As a sub class of Mobile Ad hoc Networks (MANETs), VANETs provide communication by forwarding datagram over multi hop wireless links. It facilitates the communication among Vehicle to Vehicle (V2V) and Vehicle to Infrastructur...

In view to provide continuous services for passengers, mobility management plays a major role in Vehicular Ad hoc Networks (VANETs). As Network Mobility (NEMO) is known for its high mobility, it becomes extremely suitable for VANETs. The vision for VANETs is road safety and aimed for efficiently dealing the mobility of a set of mobile nodes using Mobile Routers (MRs). However, inefficient routi...
