Efficient Path Planning Based On Hybrid Routing Protocols over A Vanet

Abstract

Vehicular Ad-hoc Network (VANET) is an
emerging communication Infrastructure which
facilitates the connectivity among vehicles through
vehicle-to- vehicle (v2v) and vehicle-to-roadside (v2R)
communications and is characterized by high dynamic
topology of nodes in the network. Due to this high
mobility of vehicles it is quite challenging to perform
packet delivery from source to destination in case of any
destruction or congestion in the network. In order to
overcome this problem a novel path planning technique
must be implemented reducing packet loss and end to
end delay which includes communication among
vehicles, road side units(RSUs) and vehicle traffic
servers. Hence we propose a routing protocol with GPS
and map aware capabilities that includes four metrics
such as distance to destination, vehicle’s density,
vehicle’s trajectory and available bandwidth in order to
make forwarding decisions. This protocol is being
justified and it is shown that it reduces packet loss and
end to end delay in the network thus increasing the
efficiency of routing.
