Entering the information era, the current needs of global community is increasing very rapidly. Vehicular Ad-hoc Networks (VANET) has drawn significant attentions from both industry and academia as an important developmnt of vehicular communication technology. VANET is one of open network and communication media without security mechanism. There are many kinds of security threat that can interrupt data communication in VANET. Wormhole attacks as one of security threat can be a good challenge in VANET security research.  In this paper, we evaluate performance of reactive routing protocol on VANET with wormhole attack scheme. The project is simulated using NS-3 in Ubuntu platform with performance analysis of routing protocol by changing of initial power and node density. We conclude that throughput values are increasing along with the changing of initial power while the delay values are decreasing rapidly. By the changing of node density, the highest delay value is 0.122 ns on 10 nodes condition and 0.215 Mbps for throughput value on 8 nodes condition.

This article analyzes and compares the service quality metrics in reactive routing protocols AODV and DSR in VANET. Through the revision of the recorded information we study the characteristics, classification, applications and different traffic models. All these parameters are taken into account in the modelling of vehicular traffic in the downtown of Loja City. In order to get the corresponding results, three different scenarios each with a different node density have been created. According to the collected data, it is possible to verify which routing protocol is the most suitable for the Ad-Hoc networks proposed in this study.

A Mobile Ad-Hoc Networks (MANET) is widely used in many industrial and people's life applications, such as earth monitoring, natural disaster prevention, agriculture biomedical related applications, and many other areas. Security threat is one of the major aspects of MANET, as it is one of the basic requirements of wireless sensor network, yet this problem has not been sufficiently explored. The main purpose of this paper is to study different MANETs routing protocols with three scenarios of Denial of Service (DoS) attacks on network layer using proactive routing protocol i.e. Optimized Link State Routing (OLSR) and Reactive routing protocols like Ad hoc On-Demand Distance Vector (AODV), Hybrid routing protocols like Geographic Routing Protocol (GRP). Moreover, a comparative analysis of DoS attacks for throughput, Data loss, delay and network load is taken into account. The performance of MANET under the attack is studied to find out which protocol is more vulnerable to the attack and how much is the impact of the attack on both protocols. The simulation is done using OPNET 17.

High relative node velocity and high active node density have presented challenges to existing routing approaches within highly scaled ad hoc wireless networks, such as Vehicular Ad hoc Networks (VANET). Efficient routing requires finding optimum route with minimum delay, updating it on availability of a better one, and repairing it on link breakages. Current routing protocols are generally focused on finding and maintaining an efficient route, with very less emphasis on route update. Adaptive route update usually becomes impractical for dense networks due to large routing overheads. This paper presents an adaptive route update approach which can provide solution for any baseline routing protocol. The proposed adaptation eliminates the classification ofreactiveandproactiveby categorizing them aslogical conditionsto find and update the route.

Vehicular Ad Hoc Networks (VANET) is an emerging application of Intelligent Transport System, which is mainly to assist public safety applications such as collision avoidance between the vehicles or between vehicles and other obstacles such as pedestrians. At the same time, it challenges the data communication because of its high mobility, short link lifetime, and frequent network fragmentations. Existing spectrum standard for vehicular communication underutilizes the frequency bands in the sparsely used regions when the licensed users are not deploying them even at the peak hours of the road. Congestion or route stalling is unavoidable in vehicular networking and this builds an impression that there is always a shortage of spectrum. A solution would be to have a cognitive radio that can utilize the spectrum that is not heavily used so as to ease congestion in other areas. This chapter brings out the application of cognitive radios in vehicular environments, a new and relatively less explored area of research. This chapter looks into a few existing studies in the literature which have focused on spectrum sensing techniques, routing methodology, and security for cognitive radio vehicular networks. In addition, this chapter also discusses the impact of changes in the vehicular network on the radio propagation channel and in turn on the operation and performance of the cognitive radio vehicular network. Finally, future directions in research have highlighted the existing challenges in specific areas.
