Performance Analysis of Routing Protocols in Realistic Environment for Vehicular Ad Hoc Networks

Abstract

Vehicular Ad hoc Network (VANET) is a new way of communication which includes communication betweenvehicles moving at high speeds on the roads. VANET developed several new applications like traffic engineering, traffic management, provides emergency information to avoid accidents and other user applications. VANETs are similar to Mobile Ad hoc Networks (MANETs) but with different characteristics like, movement at high speeds, mobility, sufficient storage and processing power, unpredictable node density and difficult communication environment with short link lifetime etc. So for testing of any protocol for VANET needs realistic enviorment. In this paper, we create realistic environment for the performance analysis of proactive and reactive routing protocol in city scenarios is presented. The protocols evaluated are Ad hoc On demand Distance Vector (AODV), Ad-hoc On-demand Multipath Distance Vector Routing (AOMDV) and Destination Sequence Distance Vector (DSDV). In simulations, maps are used to model topology using traffic simulator and then vehicles with different parameter like length, maximum speed and acceleration etc. run on these topologies. The performance evaluation matrices used in this paper are packet delivery ratio and End to End Delay.

Performance evaluation of routing protocols based on realistic traces from driving simulator

“…), traffic density, and speed limits. However, our simulator uses completely different mechanism to generate traffic flow compared with some relatively advanced simulators at present that also aim to mimic the very detailed part of vehicle movement [11] [19] [21]. Models in some of these simulators also consider the effect of intersections, but vehicles behave unnaturally (e.g.…”

Reliable and Efficient Routing Mechanisms for Vehicular ad-hoc Network

“…Reza Fotohi et al improved AODV routing protocol by Limiting Visited Hop Count mechanism [19]. Vidhale et al, evaluated the MANET routing protocols in VANET environment by using different mobility models available in VanetMobiSim [20].…”

Efisien Epidemic: Pemilihan jarak terjauh dan arah pergerakan kendaraan untuk pendistribusian pesan darurat pada VDTN

“…Ragam penelitian dalam hal pendistribusian pesan yang dikembangkan pada penelitian sebelumnya, menggunakan protokol Epidemic sebagai protokol dasar. Epidemic algorithms for reliable and efficient information dissemination in vehicular [5], Prioritized Epidemic routing for opportunistic networks [6] merupakan contoh pengembangan dalam hal pendistribusian pesan menggunakan protokol Epidemic. Kelemahan penggunaan protokol Epidemic dalam hal pendistribusian pesan adalah jika setiap node diizinkan untuk melakukan penularan pesan pada setiap node tetangganya, maka terdapat banyak pesan dalam jaringan, sehingga dapat menurunkan kinerja dari jaringan.…”
