Cross Layer Design Method for Efficient Data Delivery in VANET for City Scenarios

Abstract

Vehicular Ad-hoc Networks plays the vital role in wireless communication networks. It provide safety, security and most probably provides the entertainment as well. The performance of this wireless communication depends upon the how better routing decisions takes place in the network. The routing of data determine by the routing protocols being used in the communication and depends on different scenarios i.e. the city and the highway. OLSR (optimized link state routing protocol) is used to provide best QOS under very low and high density of vehicles. Hence OLSR is used to find the best route in all kind of density environment in city scenario. NS 3 simulator is used to validate the cross layer routing on IEEE 802.11p by comparing in terms of packet delivery ratio (PDR), throughput and overhead for the protocols: Ad-hoc On-Demand Distance Vector routing (AODV) and Open Link State Routing (OLSR) protocol.
