Goodput and PDR analysis of AODV, OLSR and DYMO protocols for vehicular networks using CAVENET

摘要

A Vehicular Ad-Hoc Network (VANET) is a form of Mobile Ad-Hoc Network (MANET), which enables communication between vehicles and nearby roadside infrastructure through a wireless sensing device installed in vehicles. In VANETs and MANETs, the topology of network changes very often, therefore implementation of efficient routing protocols is very important problem. In VANETs, the mobility pattern of nodes is restricted along roads and is affected by movement of neighbour nodes. In this paper, we present a simulation system for VANET called CAVENET. In CAVENET, the mobility patterns of nodes are generated by one-dimensional cellular automaton. We implemented three routing protocols on CAVENET (AODV, OLSR and DYMO) and investigated their performance. We considered as evaluation metrics for simulation goodput and Packet Delivery Ratio (PDR). The simulation results have shown that DYMO protocol has better performance than AODV and OLSR protocols.
