Routing In Vanets For Freespace And Tworayground Propagation Lossmodels

Abstract

Adhoc networks are local area networks(LAN) which are built to connect the devices.The term Adhoc implies spontaneous because these networks often bypass a router.Formed by wireless hosts like mobile and routes between the nodes may contain multiple hops.Vehicular ad hoc networks(VANETs) is a part of mobile ad hoc networks(MANETS)-where networks are created and tries to communicate,send information among the vehicles. We used the performance of OLSR and AODV using and FreeSpace, TwoRayGroundPropagationLossModel to evaluate Packet Delivery Ratio,Throughput,Overhead as metrics.The simulation results show that with varying speeds OLSR is suitable when compared to AODV.
