Implementation of Protocol for Efficient Data Storage and Data Dissemination in VANET

Abstract

This paper deals with the protocol design for Efficient Data Dissemination and Data Storage in vehicular adhoc network (VANET). Here a large amount of data is distributed to a dense vehicular network from roadside unit as well as from on board unit using WAVE and VIPER protocol respectively. It is proposed that the system will consists of one control node as a roadside unit and two mobile nodes as an on-board unit. Data is disseminated between the mobile nodes via control node using push-based V2V/V2I dissemination technique, and then data which is disseminated through control node in all mobile nodes are stored into the memory of AVRATMEGA32. Stored data can be retrieved for analysis of accident cause or any emergency situation occurs. Analog to digital conversion is required during disseminating data between control node and mobile node. The parameters used for the verification of data dissemination and data storage are Temperature, Location of vehicle and accident cause which depends on the event occurred at the node. Also a hardware model is designed which uses AVR ATMEGA32 micro-controller and RF Trans-receiver module and WINAVR and Cygwin is used for programming.
