Efficient Data dissemination for Topology managementin VANETs

Abstract

Recent research, development and standardization advances in vehicular ad hoc networks (VANETs) have motivated increasing interest in various data services for in-vehicle consumption in terms of ‘commerce’ on wheels. These include a wide variety of applications: local information (e.g., traffic notification, map updates, location-based advertisements) pushed to vehicles; or specific data pulled from Internet servers (e.g., neighborhood parking, reviews of local restaurants, and video clips of local attractions). Here the process of Dissemination refers to the field of communication, means to broadcast a message to the public without direct feedback from the audience. Dissemination takes on the theory of traditional view of communication, which involves a sender and a receiver. The traditional communication view point is broken down into a sender sending the information, and receiver collecting the information for further processing. The second terminology used in the process is Vehicular ad hoc Network (VANETs) that uses cars as mobile nodes to create a mobile network. A VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 300 meters of each other to connect and thus creating a network with a wide range. As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile internet is created. It is estimated that the first systems that will integrate this technology are police and fire vehicles to communicate with each other for safety purposes. Here the entire process has been built up in an order to make use of VANETs in such a manner that there is assurance of 100% correct data transfer from a source to destination with minimal hopping/shifting of data from one node to another selecting the shortest path using GPS system which is guiding the vehicle in route.
