Improved greedy routing protocol for VANETEditor IJCATR
VANET (vehicular ad-hoc network) is a classification of MANET in which vehicles act as mobile node and provides 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 the given paper, we surveyed various VANETs protocols and along with its advantages and
disadvantages. We compare our proposed protocols via NS-2 based simulations and show the performance of different protocols

Challenging Issues in VANET Network and its Routing Algorithms-An Analysisidescitation
Vehicular Ad hoc Network (VANET), a rapidly
deployed wireless network, is a subclass of mobile ad hoc
networks (MANET) that uses multi-hop routing to provide
network connectivity among vehicles (V2V) or vehicle to road-
side equipments (V2R). VANETs have received increasing
research attention in recent years because of its vast
applications like safety, comfort and entertainment. Variations
with time in network topology impose new challenges for
routing protocols in such networks as traditional routing
protocols are not suitable for VANETs. This work is an attempt
to figure out the challenges in VANET comprehensively in
conjunction with the recommended routing protocols by
comparing the existing routing protocols with respect to
existing challenges.
VANET Security against Sybil Attack by Using New SRAN Routing ProtocolEditor IJCATR
A VANET facilitates communicate between vehicles and between vehicles and infrastructure. Vehicular Ad-Hoc Network
is a sub type of Mobile Ad-Hoc Network i.e. MANET. Now days, road traffic activities are one of the most important daily routines
worldwide. VANET provides you most of information that are required for better safety and driving such as an accurate weather
description or early warnings of upcoming dangers. To successfully deploy VANET, security is one of the major challenges such as
protection from selfish vehicles that may block or mess traffic, bogus notifications etc. that may harm and losses lives, that must be
addressed. Sybil attacks have become a serious threat as they can affect the functionality of VANETs for the benefit of the attacker.
The Sybil attack is the case where a single faulty entity, called a malicious node, can create multiple identities known as Sybil nodes or
fake nodes. This project detects and prevents the Sybil attack using “Secure Routing for Ad Hoc Network” (SRAN) routing protocol.
SRAN is based on AODV protocol. In our proposed work, we have developed SRAN protocol to maintain routing information and
route discovery in such manner that will detect as well as prevent Sybil Attack. Each node will have a unique identity and their entry in
route table. SRAN Protocol easily detects such route that is not valid anymore for communication. It deletes all the related entries from
the routing table for those invalid routes
Efficient Routing Protocol in the Mobile Ad-hoc Network (MANET) by using Gene...IOSR Journals
An Ad hoc network is a collection of wireless mobile hosts forming a temporary network without the
aid of any centralized administration or standard support services. MANET can be defined using unstable
network infrastructure, self-organizing network topology and independent node mobility. This becomes
obtainable due to their routing techniques; in other terms, routing is a backbone for MANET. However, due to
network load routing performance of MANET is degraded thus, some optimization on network routing strategy
is required.
In this paper, we introduce a new technique by using the concept of Genetic algorithm (GA) with
AODV Protocol to make routing decision in computer network.
The goal of this paper is to find the optimal path between the source and destination nodes and increased the
QoS and Throughput. We implemented and compare this a new technique with the traditional AODV, and we
shows that the new technique is better performance than the traditional AODV.

A Vehicular Ad Hoc Network (VANET) is a network formed purely among vehicles without presence of any
communication infrastructure as base stations and/or access point. Frequent topological changes due to
high mobility is one of the main issues in VANETs. In this paper we evaluate Ad-hoc On-Demand Distance
Vector (AODV) and Optimized Link State Routing (OLSR) routing protocols using 802.11a and 802.11p in
a realistic urban scenario. For this comparison, we chose five performance metrics: Path Availability, Endto-
End Delay, Number of Created Paths, Path Length and Path Duration. Simulation results show, that for
most of the metrics evaluated, OLSR outperforms AODV when 802.11p and that 802.11p is more efficient
in urban VANETs.

COMPARATIVE ANALYSIS OF ROUTING PROTOCOLS IN MOBILE AD HOC NETWORKSijcax
A Mobile Ad Hoc Network (MANET) is a collection of mobile nodes that want to communicate without any
pre-determined infrastructure and fixed organization of available links. Each node in MANET operates as
a router, forwarding information packets for other mobile nodes. There are many routing protocols that
possess different performance levels in different scenarios. The main task is to evaluate the existing routing
protocols and finding by comparing them the best one. In this article we compare AODV, DSR, DSDV,
OLSR and DYMO routing protocols in mobile ad hoc networks (MANETs) to specify the best operational
conditions for each MANETs protocol. We study these five MANETs routing protocols by different
simulations in NS-2 simulator. We describe that pause time parameter affect their performance. This
performance analysis is measured in terms of Packet Delivery Ratio, Average End-to-End Delay,
Normalized Routing Load and Average Throughput.

A Review of Ad hoc on demand distance vector routing and proposed AR-AODVEditor IJMTER
Mobile Ad-hoc networks are a key in the evolution of wireless networks. In mobile
ad hoc networks, there is no centralized infrastructure to monitor or allocate the resources
used by the mobile nodes. The absence of any central coordinator makes the routing a
complex one compared to cellular networks. The Ad hoc On Demand Distance Vector
(AODV) routing algorithm is a routing protocol designed for ad hoc mobile devices. AODV
uses an on demand approach for finding routes .A class of routing protocols called ondemand protocols has recently found attention because of their low routing overhead. The ondemand protocols depend on query floods to discover routes whenever a new route is needed.
Such floods take up a substantial portion of network bandwidth. The routing in Mobile ad hoc
network is difficult and number of reactive routing protocols like AODV, DSR, and DSDV
has been implemented. In this paper, an attempt has been made to thoroughly study all
AODVs and a new AODV is proposed called AR-AODV
A Survey of Enhanced Routing Protocols for Manetspijans
Mobile Ad Hoc Networks (MANETs) form a class of dynamic multi-hop networks consisting of a set of
mobile nodes that intercommunicate on shared wireless channels. MANETs are self-organizing and selfconfiguring multi-hop wireless networks, where the network structure changes dynamically due to the node
mobility. There exists no fixed topology due to the mobility of nodes, interference, multipath propagation
and path loss. Hence efficient dynamic routing protocols are required for these networks to function
properly. Many routing protocols have been developed to accomplish this task. In this paper we survey
various new routing protocols that have been developed as extensions or advanced versions of previously
existing routing protocols for MANETs such as DSR, AODV, OLSR etc.
Improved routing scheme with ACO in WSN in comparison to DSDVijsrd.com
Routing is the process of selecting best paths in a network in terms of energy and distance. In adhoc it is critical to collect the information in an efficient manner as it has limitations in terms of centralized congestion. In such case to perform the effective communication there is the requirement of some such routing approach that can provide the routing with optimized path. In this work, ACO based routing approach is defined to generate the optimized path in comparison to DSDV over the network. The presented approach is implemented in matlab environment and obtained results shows the effective results in terms of optimized path.
The Effects of Speed on the Performance of Routing Protocols in Mobile Ad-hoc...Narendra Singh Yadav
Mobile ad hoc network is a collection of mobile nodes communicating through wireless channels without any existing network infrastructure or centralized administration. Because of the limited transmission range of wireless network interfaces, multiple "hops" may be needed to exchange data across the network. Consequently, many routing algorithms have come into existence to satisfy the needs of communications in such networks. Researchers have conducted many simulations comparing the performance of these routing protocols under various conditions and constraints. One question that arises is whether speed of nodes affects the relative performance of routing protocols being studied. This paper addresses the question by simulating two routing protocols AODV and DSDV. Protocols were simulated using the ns-2 and were compared in terms of packet delivery fraction, normalized routing load and average delay, while varying number of nodes, and speed.
Design of an adaptive sign based routing protocol in vanet for sophisticated ...IJARIIT
With the advancement in the communication technology and an increase in the number of vehicles, the Vehicle Ad
hoc Network (VANET) has become an emerging field of study. The major applications of VANETs are in highways, but in
sophisticated environments such as forest area, hill stations, private museum or large park etc., where visitors across the
country pass through several locations, and there doesn’t exist a proper communication among the vehicles. So in this type of
locations, we need an intelligent routing strategy for the On Board Unit (OBU) to adapt and communicate with the
neighbouring vehicles. In this paper, a strategy is proposed where in, the vehicles communicate with each other or with the
road side units (RSU) by passing some sign bits with positive or negative polarity. A simple simulation is performed on 100 to
200 vehicles demonstrating passing of data from source to destination.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
2. ABSTRACT
This seminar deals with the different
routing concept that measures the performance of the
VANET. Vehicular Ad Hoc Network (VANET) is a sub class of
mobile ad hoc networks.
3. INTRODUCTION
VANET :- “provides wireless communication among vehicles and
vehicle to road side equipments.” The networks with the absence
of any centralized or pre-established infrastructure are called Ad
hoc networks
It is a sub-class of mobile ad hoc networks (MANET).
Used for safety , comfort and entertainment as well.
5. AIMS AND OBJECTIVES
Aim is to identify which ad hoc routing method has
better performance in VANET.
To achieve this aim we have set the following objectives:
1. Finding problems with traditional MANET routing protocols
used in VANET.
2. Finding problems with various proposed routing techniques
for VANET.
3. Comparing performance results of both routing protocols.
6. TRADITIONALAD HOC ROUTING
This ad hoc routing uses the theoretical analysis of
routing protocols for VANET.
1. Mobile ad hoc networks routing
2. Topology based routing
a. Proactive routing
b. Reactive routing
c. Hybrid routing
7. 1. Mobile ad hoc networks Routing:
There is no fixed network topology
Adopt any runtime topology due to dynamic behaviour
Route discovery, Route maintenance, and sudden change in
the topology are major barriers in MANET.
2. Topology Based Routing:
It was developed to meet the dynamic nature of the ad hoc
networks
It uses link’s information within the network to send the data
packets
8.
9. Proactive routing:
These are based on shortest path algorithms.
The information in this routing is in the form of tables.
Proactive algorithms: a. Link-state routing (e.g. OLSR)
b. Distance-vector routing (e.g. DSDV)
10. Reactive Routing:
It is developed to overcome the overhead that was created by
the proactive routing protocols.
Route discovery can be done by sending RREQ (Route Request) .
Reactive routing can be classified either as source routing or
hop-by-hop routing.
Ad Hoc On Demand Distance Vector Routing (AODV) and
Dynamic Source Routing (DSR) are different types of Reactive
Routing protocols.
11. VANET ROUTING PROTOCOLS
Vehicular Ad hoc Network Routing:
High mobility, frequent changes in topology and limited life
time
Other factors such as road layout and different
environments
VANET uses position information of the participating nodes
within the network to take routing decisions.
12. Position Based Routing:
Uses positions of nodes to provide successful communication.
It assumes that each node have knowledge about its physical/
geographic position by using determining services.
As compared to topology based routing, it uses the additional
information.
It provides hop-by-hop communication to vehicular networks.
13. It’s protocol consists of many major components. Those are:
a. Beaconing
b. Location Service and Servers
c. Recovery and Forwarding Strategies
i. restricted directional flooding
ii. hierarchal forwarding
iii. greedy forwarding
14. Greedy Perimeter Stateless Routing-GPSR:
- It is the best example of position based routing.
- Uses the nearest router ‘s information of destination to forward
packets.
- Helps the path with less interference of topology information.
- GPSR protocols divided into two groups:
1. Greedy Forwarding
2. Perimeter Forwarding
15. Geographic Source Routing (GSR):
- It fails in the presence of radio obstacles.
- It deals with high mobility of nodes and uses road layout to
discover routes.
- Uses Reactive Location Services(RLS) which combines both
geographic routing and road topology knowledge .
- Multiple hops, Routing Loops and Incorrect Route Selection.
16. Anchor-based Street and Traffic Aware Routing(A-STAR):
- It is also a Position based routing protocol.
- The drawback like effect of high mobility is overcome by A-
STAR.
- In this the address of the header is given to the all other nodes
that packet travels.
- This is called Anchor based Routing.
- It also deals with “Spatial Aware Routing”.
- It computes number of junctions using traffic information and
street awareness to find the path.
17. - A-STAR has two features that make it different from all other
protocols.
- A-STAR uses Statistically and Dynamically rated maps to find
number of junctions.
- Statistically Rated maps uses schedule of buses for high
connectivity.
- Dynamically Rated maps collect the latest information of traffic
in finding path.
18. CONCLUSION
The main goal is to identify different routing protocols
and to evaluate these routing protocols against each other in
VANET. Here, we suggest that Position based protocols are
more promising than Traditional ad hoc routing protocols for
VANET.
19. FUTURE WORK
In Wireless network community VANET received
attention of many researchers due to its unique nature. Here, we
only focused on the traditional and position based routing
protocols. But there some areas that need more attention. New
algorithms should be proposed to provide reliable QoS for safety
and comfort applications in VANET.
