Vehicular Ad Hoc Networks (VANETs) are classified as a subset of Mobile Ad Hoc Networks (MANETs). VANETs have the potential of improving road safety and providing travelers comfort. This network rehearses moving cars as nodes in a network to create a mobile network. As a component and concrete application of an ITS inter vehicle communication gained attention from researchers, academics and ind...

Intelligent Transportation Systems (ITS) has gain a lot of popularity due to much technological advancement in Vehicular Ad hoc Networks (VANETs). VANET provides safety and entertainment services to vehicle users. Therefore, constrained safety is a prominent feature for VANETs. Since the vehicular nodes typically moves fast than the nodes movement in other network such as Mobile Ad hoc Networks...

In order to deliver a qualitative Internet Protocol Television (IPTV) service over vehicular ad hoc networks (VANETs), a quality of service (QoS) mechanism is needed to manage the allocate of network resources to the diverse IPTV application traffic demands. Unlike other mobile network, VANETs have certain unique characteristic that presents several difficulties in providing an effective QoS. S...

Vehicular Ad-hoc Networks (VANETs) have seen significant advancements in technology. Innovation in connectivity and communication has brought substantial capabilities to various components of VANETs such as vehicles, infrastructures, passengers, drivers and affiliated environmental sensors. Internet of Things (IoT) has brought the notion of Internet of Vehicles (IoV) to VANETs where each compon...

Vehicular ad hoc networks (VANETs) are emerging to improve road safety and traffic management. Privacy and security are very important in VANETs. Existing authentication protocols to secure VANETs raise challenges such as certificate distribution and reduction of the strong reliance on tamper-proof devices. Recently, Yeh et al. proposed a portable privacy-preserving authentication and access co...

Vehicular Ad Hoc Networks (VANETs) are considered as a promising scheme to actively guarantee vehicle safety, and broadcast is a key technology for warning message dissemination in VANETs. This paper proposes a novel Position-based Multi-hop Broadcast (PMB) protocol for VANETs in view of some shortcomings of existing broadcast protocols for VANETs, such as ignoring the differences of transmissi...

Video streaming over Vehicular Ad Hoc Networks (VANETs) offers the opportunity to deploy many interesting services. These services, however, are strongly prone to packet loss due to the highly dynamic topology and shared wireless medium inherent in the VANETs. A possible strategy to enhance the delivery rate is to use redundancy for handling packet loss. This is a suitable technique for VANETs ...

Vehicular Adhoc Network (VANET), an integrated part of Intelligent Transportation System (ITS), is a real-life illustration of a self-organized Adhoc network for communication between vehicles and roadside infrastructure. VANETS has several security issues and Blackhole attack is one of those. The paper discusses Blackhole attack in VANETs and various solutions for it.

Vehicular ad hoc networks (VANETs) have an important role in urban management and planning. The effective integration of vehicle information in VANETs is critical to traffic analysis, large-scale vehicle route planning and intelligent transportation scheduling. However, given the limitations in the precision of the output information of a single sensor and the difficulty of information sharing ...
