IAEME PUBLICATION, 2020

Vehicular Ad-hoc Network (VANET) is a boundless and emerging area of research in vehicular communication technology. It is mostly utilized in safety applications and to give ease during driving. VANETs connect the vehicles and the infrastructure to share data securely during traveling on highways(urban), or interlinked roads(rural). In VANETs, all mobile nodes can move unrestrictedly in the network and can communicate with any of the nodes in the network. It is one of the foundational technology used for the safe, efficient, and entertaining transportation system. A notable time is spent by people in communicating through vehicles. To make their trip more secure and less time-consuming smart vehicles based on VANETs have emerged. To leverage the maximum benefit of VANETs, the routing protocols play a vital role. Researchers have developed applications using AODV, DSDV, DSR, and other routing protocols to manage heavy and unruly traffic. In this paper, these protocols are studied and compared based on different attributes such as recovery strategy, type of environment, traffic flow, and so on. Further, the protocols under bio-inspired algorithms were studied.

Vehicular Ad-hoc Networks (VANETs) is an improved form of Mobile Ad-hoc Networks (MANETs), where the vehicles moving in a predefined route with relatively high speed. Due to high rate of topology changes in VANETs, frequent disruption in link and excessive overhead occurs. An intelligent transportation system (ITS) is being approached by using VANET therefore the need of efficient VANET routing protocol is crucial. In VANET routing protocols, an efficient route must be established between nodes before communication can take place and it should adapt dynamic topology changes caused by rapid movement of vehicles. In this paper, different routing protocols in VANET are described which may help in designing improved routing protocols..

Vehicular ad hoc networks are more helpful in providing road safety and many other commercial applications. As routing plays very important role in VANET applications because it has to handle efficiently rapid topology changes. The most recent routing protocols are very useful in city environment but they cause end to end delay in some cases. In this paper, we have proposed a new reliable routing scheme (RRS) for VANETs by applying position based routing strategy with the consideration of nodes moving direction, and predicable mobility in city environment. It consists of two modules (1) Dynamically selecting the junctions through which the packets must pass to reach the destination and (2) applying efficient routing by keeping two hop neighbors information to forward packet between two junctions. Simulation results show that RRS performs better in terms of increased packet delivery ratio as well as decreased average end to end delay against GyTAR.

The networks that interconnect vehicles on road are called Vehicular Ad hoc Networks (VANETs). VANET is a unique type of network which comes under the shades of MANET, where the communication occurs between various vehicles moving on the paths. It is a different approach for intelligent transport system (ITS). The main target of research in VANETs is the improvements of vehicle safety by means of inter vehicular communication (IVC). Here the nodes are dynamic in nature because of this finding and maintaining route and routing process is very difficult. The performance of communication is depended on choosing the best path while communicating. The routing process is done by various routing protocols in Vehicular Adhoc Networks. The aim of this paper is to give a brief idea of VANET and focusing on categorization of routing protocols for improving the smartness of Intelligent Transport System.

Routing protocols for vehicular ad hoc networks (VANETs) have attracted a lot of attention recently [4]. Vehicular Ad Hoc Networks (VANET) is a subclass of Mobile ad hoc networks which provides a differentiate approach for intelligent transport system (ITS). The routing protocols fall into two major categories of topology-based and positionbased routing. The survey of routing protocols in VANET is important and necessary issue for smart ITS [5]. The chapter Firstly discusses concepts of VANET briefly, explores the inspiration behind their design and trace the evolution of these routing protocols analyzes and compares some different kinds of existing routing protocols in VANET, the advantages and restriction of different routing protocols, & finally pointing out some open issues and possible track of future research related to VANET routing.

VANET (vehicular ad-hoc network) is a classification of MANET in which vehicles act as mobile nodes and provide a different approach to Intelligent transport System (ITS). VANET is an emerging area for Intelligent Transportation System (ITS) which can result in increased traffic safety, collision warning through exchange of messages through wireless media. Efficient routing protocols are required for efficient communication among vehicles. In this paper, we surveyed various VANET protocols and reached its merits and demerits.

VANETs or vehicular ad hoc networks are essential & promising research areas in the ad hoc networks field. The core objective to set up VANET can upgrade road safety & diminish accidents quantity. Routing has been a complex task in VANET as the nodes are highly mobile and consequently, topology alters very quickly. Hence, it is difficult to distribute packets within the minimum period. Contemporary routing protocols cannot meet all demands and issues in VANETs routing. To provide a suitable routing protocol, the crucial factor is to analyze the VANET's protocols for routing. Hence, the paper begins by presenting the fundamental structural design of VANETs to provide a thorough account of several available routing procedures that incorporate their benefits and drawbacks. The paper concludes by providing a summary of the available routing protocols that are used in VANETs.

In this paper, the existing ad hoc on demand multipath distance vector (AOMDV) routing scheme for vehicular ad hoc networks (VANETs) is extended to a reliable low-latency multipath routing (RLLMR) scheme based on multipath link reliability, capable of determining the reliable routes preemptively. Here, the link reliability refers to the probability that a direct transmission link among any two vehicles remains constantly available for a specific period of time, which can be computed based on the position, route, and velocity of the vehicles to facilitate the reliable routing process in VANETs. In the proposed RLLMR scheme, the mathematical distribution of vehicles movements and link breakages is also considered to increase the reliability of the vehicular networks. The simulation results show that proposed RLLMR scheme performs better compared to existing schemes in terms of latency, reliability, throughput, and energy consumption at the cost of marginally increased routing overhead.
