VANETs also called as intelligent transportation system (ITS) in which vehicles communicate to provide timely information.Their aim is to provide security, information and management of network. Instead of their many advantages vehicular network is prone to various attacks. In this research removal of Sybil attack in which node creates its multiple identities and it can be affected by various ways. In previous work Sybil attack is prevented by using the timestamp. Every node has some time stamp to communicate with RSU in which identities are verified. If multiple identities exist then there must be an attacker. On high traffic roads there are number of vehicles for which RSU cannot process all vehicles and also vehicles have high mobility due to which timestamp may be collapse or may miss by vehicle. In previous work three methods were used to find the physical measurement of message that were Time of Arrival (TOA), Angel of Arrival (AOA), and Received Signal Strength (RSSI). In this work, we are using GPSR, Which Reduce the Chances of Attacks.

Some public transport vehicles embed devices that allow passengers to connect to Internet while traveling. These vehicles are true mobile Internet access zones inside public paths. These zones could be used by other vehicles moving close to them in order to have Internet access. At the same time, other vehicles in the influence area could be used as relay nodes which would increase this access area. In this paper, we present a group-based protocol and mobility model for vehicular ad hoc networks (VANETs) where each public transport vehicle forms a group of vehicles. They can access and allow access to Internet though the public transport vehicle. Each vehicle is moving inside the group and can leave and join any group at will, while all groups are moving. First, we will show the algorithm and protocol to achieve our purpose. Then, we will study the probability of having Internet access in order to demonstrate that it is a feasible proposal. Finally, we simulate a study case based on real values in order to obtain the performance of our proposal in terms of several network parameters such as the number of hops per route, the network traffic, the page response time, network delay, network load and so on.

“…From this data, we look at instantaneous snapshots in both urban and highway VANETs, and study the underlying graph where nodes are vehicles and edges exist between vehicles which can establish 1-hop communication. Works in [7] and [8] also study the data from highway I-80 to address the challenge of routing in sparse VANETs. For each scenario, we consider 3 connectivity regimes -high, medium and low connectivity -and the corresponding vehicle densities (we assume a penetration rate of 100%, as well as 100% success rate for the exchanging of messages within the communication ranges, as defined before, and 0% in all other cases).…”

Abstract-Developing routing protocols for Vehicular Ad Hoc Networks (VANETs) is a significant challenge in these large, selforganized and distributed networks. We address this challenge by studying VANETs from a network science perspective to develop solutions that act locally but influence the network performance globally. More specifically, we look at snapshots from highway and urban VANETs of different sizes and vehicle densities, and study parameters such as the node degree distribution, the clustering coefficient and the average shortest path length, in order to better understand the networks' structure and compare it to structures commonly found in large real world networks such as small-world and scale-free networks. We then show how to use this information to improve existing VANET protocols. As an illustrative example, it is shown that, by adding new mechanisms that make use of this information, the overhead of the urban vehicular broadcasting (UV-CAST) protocol can be reduced substantially with no significant performance degradation.
