N-Hop broadcast and Street Broadcast Reduction algorithm using OMNeT++ and Google Earth plugin

Abstract

VANET are the systems used to collaborate the wireless devices installed on the vehicles, for transfer of messages. The implementation of algorithms on VANET in actual device is preceded by simulation of the same on a simulating environment like OMNeT++, SUMO, etc. This paper presents a study and implementation of VANET Broadcasting algorithms, and algorithms which are able to solve the problem of broadcast storming. With efficient use of resources, the transmission of signals to the different vehicles have been scalable to be broadcasted using two protocols namely, N-Hops Weighted p-persistence Broadcasting which is able to disseminate the data to different vehicles in all the regions covering the broadcast range. Another algorithm is Street Broadcast Reduction, which covers the area through different roads and effectively send the warning and alert messages to the vehicles, using the distance based schemes. The problems in VANET broadcast has been addressed, and have been implemented using OMNeT++, SUMO and Google Earth.
