SODV speed based ad hoc on demand vector link routing protocol: A routing protocol for VANET networks

Abstract

ITS intelligent transportation systems represent one of the most desirable technologies, when the safety, efficiency, and comfort of everyday road travel need to be improved when a great number of people are dying because of road accidents. Vehicular Ad-hoc Network, VANET, is one of the emerging technologies, which will make the life easier. VANET provide an important knowledge to drivers. This knowledge is provided by one vehicle to another using vehicle to vehicle communications. To make VANET successful, routing protocols should be given a greater attention. In this paper, we present SODV Speed based On Demand Vector link routing protocol which is an AODV based routing protocol. SODV improve the routing process and make the choice of neighboring vehicles more and more relevant by taking into consideration the vehicle velocity in packet transmission procedure. Performance analysis illustrates that SODV outperform AODV routing protocol especially in transmission delay.
