In recent years, Vehicular Ad Hoc Network (VANET) has developed significantly. Coordination between vehicles can enhance driving safety and improve traffic efficiency. Due to the high dynamic characteristic of VANET, security become one challenging problems. Trust message is a key element in VANET. This paper proposes Manhattan Distance Based Management model (MDBTM) VANET environment which sol...

Vehicular Ad-hoc Network (VANET) is taking more attention in automotive industry due to the safety concern of human lives on roads. Security is one of the safety aspects in VANET. To be secure, network availability must be obtained at all times since availability of the network is critically needed when a node sends any life critical information to other nodes. However, it can be expected that ...

Vehicular Ad-Hoc Networks, are a specified class of Mobile Ad-Hoc Network, in which vehicles are nodes VANET provides interaction between vehicles and road sides units. VANET now-a-days is affecting a large area of research due to its wide range of applications and special characteristics like movements constraints, On board sensors, Unlimited battery power, high node mobility etc . The main is...

Vehicular Ad hoc Network (VANET) is an ad hoc network in which vehicles acts as nodes. It is an application of MANET. VANET is becoming an active area of research because it has tremendous potential to improve safety of vehicles and traffic efficiency. We use the VANET instead of Mobile Ad hoc Network (MANET) due to high mobility of the vehicles as MANET does not support high mobility. Wireless...

A vehicular ad hoc network (VANET) is a type mobile ad hoc network which is developed to increase physical safety of vehicles’ derivers. Many parameters affect the performance of VANET. Packet size and packet rate are two important parameters that need to be considered when using VANET. Different values of these parameters provide different network performance. Using large packet size leads to ...

The causes of road accidents lead to emergency communication between vehicular nodes. It is true that the onthe-spot messaging helps in rescuing victim’s life. The establishment of unprepared communication across vehicular nodes is possible with the intervention of automatic messaging. This leads to active research in data dissemination methods using heterogeneous devices. In this paper, the da...

The main objective of congestion control in VANET is to best exploit the available network resources and to minimize the congestion in the network. In this context, we present a congestion control approach, based on time synchronization approach reducing number of messages, to ensure reliable and safe communication within VANET. It supports discarding of similar types of messages and time synch...

Vehicles in VANET can form wireless ad hoc mesh networks (VMeshes) that are mobile, constantly changing both in size and the geographic area they cover. We focus on how the VMeshes can be used to capture and retain certain transient information on the road within a given region of interest for a certain period of time, without any infrastructure support. In this paper, we study this ‘‘storage c...

Vehicular Ad hoc Networks (VANET) broadcast messages regarding road and environmental conditions. Due to its design, VANET inadvertently introduced security privacy issues. Many researchers have suggested various approaches address these shortcomings as the deployment of becomes more widespread. Nevertheless, solutions could not all in VANET. Furthermore, proposed incur high costs terms computa...
