In the vehicular ad hoc networks (VANET), various authentication schemes have been proposed for secure communications. However, the previous schemes are inefficient because each vehicle needs to share and keep a large number of session keys for communicating with the other vehicles on the VANET. To overcome the above drawback, we propose a new authenticated communication scheme for the VANET. I...

Vehicular ad-hoc network (VANET) have been impartially a hot research area over the recent years. Due to increase in vehicle crashes and fatalities, Vanet fascinate so much attention of both academia and industry. Vehicular ad-hoc networks (VANETs) are the dynamic subcategory of mobile ad-hoc network (MANET) in which mobile node presents set of smart vehicles on road. This paper basically descr...

In this paper we investigate the possibility of a new type of application, namely multiplayer games, in a Vehicular Ad Hoc Network (VANET) environment. First, we analyze the available empirical data on travel and traffic volume in the United States, and point out the most important challenges that have to be met in order to enable multiplayer games over VANET. We then propose a new paradigm of ...

Vehicular Ad-hoc Network (VANET) has become an active area of research due to its major role to improve vehicle and road safety, traffic efficiency, and convenience as well as comfort to both drivers and passengers. This paper thus addresses some of the attributes and challenging issues related to Vehicular Ad-hoc Networks (VANETs). A lot of VANET research work have focused on specific areas in...

In Vehicular Ad-Hoc Networks (VANETs), location service protocol is utilized to locate locations of nodes to be used by position-based routing algorithms before the start of communication between source and destination. The existing location services proposed for Mobile Ad-Hoc Networks (MANET) suffer from poor scalability in VANET environments. Due to importance of positioning in VANET environm...

Trusted routing in VANET is a challenging task due to highly dynamic network topologies and openness of wireless architecture. To provide secure routing among the Vehicular Ad-hoc Networks (VANET) and to avoid selfish nodes, an Optimized Node Selection Routing Protocol (Trusted-ONSRP) of VANET has been designed based on trusted metrics using a Trusted Computing Algorithm. The results stated tha...

The new type of Mobile Ad hoc Network which is called Vehicular Ad hoc Networks (VANET) created a fertile environment for research. In this research, a protocol Particle Swarm Optimization Contention Based Broadcast (PCBB) is proposed, for fast and effective dissemination of emergency messages within a geographical area to distribute the emergency message and achieve the safety system, this res...

The high mobility of VANET makes information exchange across the network excessively difficult. Traditional approaches designed for stationary networks are not applicable due to the high dynamics among the nodes. Applying the routing techniques tailored for general mobile networks inevitably brings huge traffic burden to the crowded urban VANET and leads to low efficiency. To make the informati...

Vehicular ad hoc network (VANET) technology uses moving vehicles as nodes in a network to create a mobile network. A VANET turns every participating vehicle into a wireless router or node. 100 to 300 meter distance is allowed between vehicles to cover a wide network range. In VANET network topology is rapidly changed due to high mobility of nodes. VANET uses infrastructure support to handle tim...

In a 1-D linear vehicular ad hoc network (1-DL-VANET), some vehicles may leave the network (e.g., at highway exits), which may make the 1-DL-VANET disconnected. Thus, it is important to analyze the connectivity of the 1-DL-VANET. When removal of any (k− 1) arbitrary nodes from a network does not disconnect the network, the network is said to be k-connected. In this paper, we investigate the k-c...
