Improving The Traffic Efficiency And Road Side Safety

Today it isn't sufficient to expect that the individual who approaches with information is authorized, it is fundamental to affirm that approval and ensure that the decoding conventions are followed as per the organization's data security arrangements and methods. Identity and authorization management (IAM) applications and encryption by and large are viewed as two of the most vital segments of layered security protocols.

A sender wanting to send a message must first encode it in a meaningful form for the receiver. Encoding is the translation of an idea or concept into a message, it is one of the key stages in the communication process. The sender must be cognisant of the receiver 's knowledge and use symbols understandable to the receiver. These symbols may be verbal or non-verbal, examples of which are words and gestures. Improper encoding is a barrier to communication as it will inhibit the decoding of the message and distort the information. An example of poor encoding would be an advertisement using the same message throughout multiple countries in which some words

(Urmson). Driverless cars also have other sensors, including four radars, a GPS, an inertial measurement unit, and a wheel encoder. The radars detect obstacles. The GPS, inertial measurement unit, and the wheel encoder determine where autonomous vehicles are currently and track where they go (Guizzo).

Automotive application such as devices and dashboard displays would then share information with vehicles that are connected, with this the vehicles will also be able to exchange data to roadside units that are connected to the network this would include streetlights, traffic lights, trains that cross road etc. All of which will be connected to

Abstract-Using the Global Positioning System technology this system determine the location of the vehicle, and an embedded wireless system using ARM-7 micro controller controls the vehicle determining the condition of the vehicle and the driver. This system was mainly proposed for security reasons. This ARM-7 micro controller has a control over both the software and hardware. The two hard wares used here are GSM system and GPS system. The software stores the data and retrieves it for the user guidance. ARM-7 monitors all the components of the vehicle.

Authentication means verifying the identity of someone (a user, device, or an entity) who wants to access data, resources, or applications. Validating that identity establishes a trust relationship for further interactions.

Secure communication means that two authorized parties (transmitter and receiver parties) are communicating and do not want a third

Key management is a fundamental problem in securing mobile ad hoc networks (MANETs). In the paper, Securing Mobile Ad Hoc Networks with Certificateless Public Keys [1], Yanchao Zhang et al. presents IKM, an ID-based key management scheme as a novel combination of ID-based and threshold cryptography. In IKM the public keys of mobile nodes can be directly derived from their known IDs and some common information, thus it provides a certificateless solution. The need for certificate-based

Each sensor nodes have a key table in their RAM, during bootup process each node perform a self test to recognize their neighbours.if there is empty key table then sensor nodes starts the process of mutual authentication by broadcasting the signal to their neighbor, if the process of self authentication fails then each sensor node sends the signal to cluster head to provide the required keys in their key table.. Each entry in the key table is linked to routing table to recognize their cluster head to route the sensed data.

A VANET network is a subset of ad hoc networks where each mobile node is an intelligent vehicle equipped with communication resources (sensor). In vehicular networks, there are three modes of communication, communications Vehicle-to-vehicle (V2V), communications Vehicle-to-Infrastructure

In this variety of attack, the protocol fields of the messages passed among the nodes is changed, there by leading to traffic subversion or Denial of Service (DoS) attacks. The subsequent sections discuss a number some of these attacks [03]

Communication is an important process of transferring information. The most important components of communication are: the sender, the receiver, a message and the feedback. First the sender who is the person or entity that is sending a message with information. The receiver gets the message from the sender. After receiving the message, he tries to encode the message and prepares a proper answer which is called, the feedback. Communication is an essential part of this modern world; being used all the time in business, pleasure, sport or many other situations.

Vehicular Communication System plays a major role in the development of Intelligent Transportation System(ITS) which enable the users to make safer, and 'effective ' use of transport networks and aim to provide innovative services relating to different modes of transport and traffic management.In

Over the years, the technology has become more sophisticated, this technology can be suitably adapted for cars on the streets. In an automated process, AGVs are programmed to communicate with other cars on the street to ensure it is moving smoothly. Today, the
