Due to many challenging issues in vehicular ad-hoc networks (VANETs), such as high mobility and network instability, this has led to insecurity and vulnerability to attacks. Due to dynamic network topology changes and frequent network re-configuration, security is a major target in VANET research domains. VANETs have gained significant attention in the current wireless network scenario, due to their exclusive characteristics which are different from other wireless networks such as rapid link failure and high vehicle mobility. In this are, the authors present a Secured and Safety Protocol for VANET (STVAN), as an intelligent Ad-Hoc On Demand Distance Vector (AODV)-based routing mechanism that prevents the Denial of Service attack (DoS) and improves the quality of service for secured communications in a VANET. In order to build a STVAN, the authors have considered a smart traffic environment in a smart city and introduced the concept of load balancing over VANET vehicles in a best effort manner. Simulation results reveal that the proposed STVAN accomplishes enhanced performance when compared with other similar protocols in terms of reduced delay, better packet delivery ratio, reasonable energy efficiency, increased network throughput and decreased data drop compared to other similar approach.
Top1. Introduction
Safety and security are two major aspects while designing any efficient routing model for vehicular ad-hoc networks. The way toward navigation in Vehicular Ad hoc Networks (VANET) is a difficult task in city conditions. Finding the briefest end-to-end associated way fulfilling defer limitation and insignificant overhead is gone up against with numerous imperatives and troubles (Kaur et al., 2016). Such troubles are because of the high portability of vehicles, the successive way disappointments, and the different obstacles, which may influence the dependability of the information transmission and directing. Business Unmanned Aerial Vehicles or what are usually alluded to as drones can prove to be useful in managing these imperatives (Chunha et al., 2016). A Detail contemplate has been done on how they are working in impromptu mode can collaborate with VANET on the ground to aid the directing procedure and enhance the dependability of the information conveyance by spanning the correspondence hole at whatever point it is conceivable (Singh et al., 2014).
In this way, an augmentation of the convention has been modified by supporting two distinctive methods for steering information: (I) conveying information (Singh et al., 2017) parcels only on the ground utilizing UVAR-G; and (ii) transmitting information bundles in the sky utilizing a responsive directing in light of UVAR-S. Recreation comes about exhibit that the half and half correspondence amongst vehicles and UAVs is in a perfect world suited for VANETs contrasted with customary vehicle-to-vehicle (V2V) interchanges. Vehicular Adhoc Networks (VANETS) empower the vehicles to communicate with each other vehicle and in addition with road side units (Lai et al., 2018). However, building up a dynamic routing policy (Rath et al., 2016) for these networks conceivably because of the substantial portability and normal changes in these networks is a tough work. In VANETS transmission joins are at the danger of separation (Abdelgadir et al., 2017).
Along these lines the advancement of the proficient directing component is required in VANETS. It is seen in writing study that the many VANET protocols solves conventional challenges in the network. Yet at the same time issues identified with blockage control should be tended to. Ant Colony Optimization based protocols for better information collection (Pournaghi et al., 2018) and route determination has been suggested by some researchers that utilized a strategy which has indicated very huge change over accessible ones. Figure1. shows a representative traffic scenario in VANET with RSU and Server. An UVAR – a UAV-Assisted VANETs directing convention was proposed, which enhances information steering and availability of the vehicles on the ground using UAVs. Be that as it may, UVAR does not completely misuse UAVs in the sky for information sending since it utilizes UAVs just when the network is ineffectively thick.
VANETS may really make to end up valuable for throughout the way with security and additionally a few business purposes activities. For example; vehicular network might be utilized to educate drivers with the goal that the likelihood of guests jams; offering higher solace and also adequacy. Remote association frameworks have permitted the majority of the advantages inside our lives and moreover enhanced our everyday productivity additionally (Halim et al., 2018). Specially appointed networks work without a characterized preset looked after foundation. VANETS working with 802.11-organized WLAN development currently got critical intrigue Due to this reason the vehicles worked with Wi-Fi mechanism (Rath et al., 2015). Another locale in which there is a ton prospect of remote advancements to make a gigantic impact might be the district of between vehicular interchanges (IVC) (Oubbati et. al, 2017). Intervehicle association (IVC) is increasing huge enthusiasm from the investigation territory and the engine vehicle industry; in which it will valuable in giving shrewd transportation framework (ITS) alongside drivers and explorers relate administrations (Ngo et al., 2014). The idea of IVC is regularly called vehicle-to-vehicle correspondences (V2V) and notwithstanding framework it alluded vehicle-to-foundation inside their transmission extend and vehicular adhoc networks (VANET) (Rahim et al., 2018).
Basic Objective of our proposed Research Work are as follows:
