Analisis kinerja jaringan VANET dengan model propagasi free space dan two ray ground pada routing AODV

Abstract

VANET is one type of Ad Hoc network that serves as a wireless network with several mobile nodes that do not have a fixed router. Each of these nodes can function as a router that can search and handle paths to other nodes within a network. Each node on the network is mobile so that the topology of the network is constantly changing. On a network, the routing protocol is something that has a lot of impact on the performance of the network.Each propagation model will certainly have different capabilities and characteristics, therefore it is necessary to research some propagation models in the specified place which will then affect QoS performance on the VANET network. Mobility simulation is done based on urban environment scenario that is around Malang City Hall. This research applies SUMO as mobile simulator and NS-2 as network simulator with AODV type reactive protocol as routing protocol which is used and use propagation model of Free Space and Two Ray Ground as comparison in NS-2.In this research to do QoS analysis with parameters in the test is End to End Delay, Jitter, Packet Delivery Ratio and Throughput. After the data collected, analysis is done by looking at the QoS between the propagation tested. The Free Space propagation model has a smaller delay time with an average of 0.1136 ms than on the Two Ray Ground propagation which has a value of 0.1696 ms. For the number of packets received successfully Free Space propagation is better with an average value of 482.06 kbps throughput compared to Two Ray Ground propagation. The results of testing and analysis prove that Free Space propagation is the right model on the VANET network used in urban environments.
