Geo-routing in urban car-2-X communication networks

Abstract

This work studies the ETSI standards regarding ITS and also studies and classifies the state of the art VANET routing protocols to identify their research issues. The most outstanding VANET geo-routing protocols are implemented in order to be evaluated. Afterwards, it introduces the Enhanced Intersection-based Perimeter Forwarding (EIPG) and subsequently the EIPG2 geoUnicast routing protocols to address the problem of Wrong Street Estimation (WSE), routing loop and partitioned networks. Finally, it introduces the Unicast-Assisted GeoBroadcast (UAG) geoBroadcast routing protocol to address the problem of broadcast storming.
