Performance Evaluation of OLSR and AODV Protocols in a VANET Crossroad Scenario

TL;DR: The simulation results shows that for big values of transmission rates, OLSR performs better than AODV and these protocols can be used for applications that tolerate this delay such as streaming and entertainment.
Abstract: In this paper, we investigate the performance of OLSR and AODV protocols in a VANET crossroad scenario. The mobility patterns of vehicles are generated by means of CAVENET (Cellular Automaton based Vehicular Network) and as communication protocol simulator, is used NS3(Network Simulator 3). For the simulations, we used IEEE802.11p standard, TwoRayGroundPropagationLossModel and sent multiple CBR flows over UDP between ten pairs source-destination. We use Packet Delivery Ratio (PDR), throughput and delay as evaluation metrics. We compared the performance of both protocols and the simulation results shows that for big values of transmission rates, OLSR performs better than AODV. For small transmission rates, the delay is less than 0.1sec and both protocols can be used for real time applications such as safety applications. For big values of transmission rate, the delay is higher than 1 sec and these protocols can be used for applications that tolerate this delay such as streaming and entertainment.

TL;DR: This work investigates on how three state-of-the-art Mobile Ad-Hoc Network (MANET) routing protocols behave over the IEEE 802.11p/WAVE stack, and shows that the DSDV and OLSR protocols have a better performance than AODV, for low-density and low-speed scenarios.
Abstract: Vehicle-to-Vehicle (V2V), Vehicle-to-Road Infrastructure (V2R) and Vehicle-to-Pedestrian (V2P) communications are paramount for paving the way for smarter, cleaner and safer cities and roads. We investigate on how three state-of-the-art Mobile Ad-Hoc Network (MANET) routing protocols behave over the IEEE 802.11p/WAVE stack, which has been recently been specified for Vehicular Ad-hoc Networks (VANETs): Ad-hoc On-Demand Distance Vector (AODV), Optimized Link State Routing (OLSR) and Destination-Sequenced Distance-Vector (DSDV). Based on ns-3 and BonnMotion simulations, we evaluate Packet Delivery Rate, Goodput, Routing Overhead and End-to-End Delay for different trajectories, average speeds, and network densities. Our results show that the DSDV and OLSR protocols have a better performance than AODV, for low-density and low-speed scenarios. Additionally, we have observed that when the number of Nodes (network density) or Nodes’ velocity increases, the OLSR protocol performs better than the other two.

TL;DR: This paper has reviewed and discussed several studies related to the routing protocols and proven that the AODV performance is better than the other ad-hoc protocols in VANET environment.
Abstract: Wireless technology is developing very fast. Most of the researchers are working in the field of wireless communication. VANET is an evolving technology in the field of wireless communication and with the advancement it will contribute more to the smart transportation system in days to come. VANET gives a communication framework that has enhanced the traffic service and helped in reducing the road accidents. Data sharing in this system is time sensitive and require quick and vigorous network connection forming. VANET is serving the said purposes but there are some issues and challenges like efficient handling of fast handovers for video streaming applications. Therefore, in this paper we have reviewed and discussed several studies related to the routing protocols to judge which one is the best for video applications in VANET. Moreover, after studying different systems made by the researchers, we have critically analyzed them and found advantages and disadvantages for the future works. Also, simulation is performed to check the delays and throughput comparisons between the routing protocols. Furthermore, with the experiments we have proven that the AODV performance is better than the other ad-hoc protocols in VANET environment.

TL;DR: The impact of vehicle density on the performance of the most well-known routing protocols is presented and quantitative metrics like overhead, packet delivery ratio, average throughput and average end to end delay are evaluated using the Network Simulator NS-3 and SUMO.
Abstract: Vehicular Ad-hoc network (VANET) is a self-organized ad hoc network, in which each vehicle, equipped with On Board Unit (OBU), participates in routing by forwarding data for other nodes. VANETs become a really hot topic and a challenging research field as it has several issues related to security, quality of service, routing protocols, etc. Although the big challenge in VANET is to design a routing protocols more suitable to route packets efficiently to their final destination, in spite of the high speed of vehicles, frequent disconnection and the highly changeable topology. This paper presents and analyses, the impact of vehicle density on the performance of the most well-known routing protocols. Quantitative metrics like overhead, packet delivery ratio, average throughput and average end to end delay are evaluated using the Network Simulator NS-3 and SUMO.

TL;DR: A fast review and comparative study of the adhoc routing protocols used in VANET and an endeavor has been made to compare six surely understood protocols AODV, DSR, OLSR, DSDV, ZRP and D SDV.
Abstract: In this paper a fast review and comparative study of the adhoc routing protocols used in VANET will be presented. The research filed in Vehicular adhoc network (VANET) is developing very fast. An extensive variety of utilizations has been served under various situation (Highway, urban, and Cities). Many protocols have been adopted to serve different topology and scenarios, these protocols faced various challenges. VANETs provide communication between vehicles moving on the roads. The routing protocols in VANET are affected by the vehicle high speed which leads to frequently link breaks between the communicated vehicles, so the adhoc routing protocols are adapted with the VANET characteristics to deliver the data between vehicles in short time. The main goal of VANET is to assemble a data system among vehicles that are moving on the roads, which enables the vehicles to communicate with each other for the safety manners. In this paper, an endeavor has been made to compare six surely understood protocols AODV, DSR, OLSR, DSDV, ZRP and DSDV. Used in VANET from the (packet deliver ratio, end to end delay, throughput, routing algorithm load, received packets, routing packets, dropped packets, ratio of packet loss, Average Jitter) point of view.

TL;DR: A logging instrument contains a pulsed neutron source and a pair of radiation detectors spaced along the length of the instrument to provide an indication of formation porosity which is substantially independent of the formation salinity.
Abstract: The Ad hoc On-Demand Distance Vector (AODV) routing protocol is intended for use by mobile nodes in an ad hoc network. It offers quick adaptation to dynamic link conditions, low processing and memory overhead, low network utilization, and determines unicast routes to destinations within the ad hoc network. It uses destination sequence numbers to ensure loop freedom at all times (even in the face of anomalous delivery of routing control messages), avoiding problems (such as "counting to infinity") associated with classical distance vector protocols.

TL;DR: The modifications address some of the previous objections to the use of Bellman-Ford, related to the poor looping properties of such algorithms in the face of broken links and the resulting time dependent nature of the interconnection topology describing the links between the Mobile hosts.
Abstract: An ad-hoc network is the cooperative engagement of a collection of Mobile Hosts without the required intervention of any centralized Access Point. In this paper we present an innovative design for the operation of such ad-hoc networks. The basic idea of the design is to operate each Mobile Host as a specialized router, which periodically advertises its view of the interconnection topology with other Mobile Hosts within the network. This amounts to a new sort of routing protocol. We have investigated modifications to the basic Bellman-Ford routing mechanisms, as specified by RIP [5], to make it suitable for a dynamic and self-starting network mechanism as is required by users wishing to utilize ad hoc networks. Our modifications address some of the previous objections to the use of Bellman-Ford, related to the poor looping properties of such algorithms in the face of broken links and the resulting time dependent nature of the interconnection topology describing the links between the Mobile Hosts. Finally, we describe the ways in which the basic network-layer routing can be modified to provide MAC-layer support for ad-hoc networks.

TL;DR: The Optimized Link State Routing protocol is an optimization of the classical link state algorithm tailored to the requirements of a mobile wireless LAN and provides optimal routes (in terms of number of hops).
Abstract: This document describes the Optimized Link State Routing (OLSR) protocol for mobile ad hoc networks. The protocol is an optimization of the classical link state algorithm tailored to the requirements of a mobile wireless LAN. The key concept used in the protocol is that of multipoint relays (MPRs). MPRs are selected nodes which forward broadcast messages during the flooding process. This technique substantially reduces the message overhead as compared to a classical flooding mechanism, where every node retransmits each message when it receives the first copy of the message. In OLSR, link state information is generated only by nodes elected as MPRs. Thus, a second optimization is achieved by minimizing the number of control messages flooded in the network. As a third optimization, an MPR node may chose to report only links between itself and its MPR selectors. Hence, as contrary to the classic link state algorithm, partial link state information is distributed in the network. This information is then used for route calculation. OLSR provides optimal routes (in terms of number of hops). The protocol is particularly suitable for large and dense networks as the technique of MPRs works well in this context.

TL;DR: With simulation based studies, the approach can be studied in detail at varying scales, with varying data applications, varying field conditions, and will result in reproducible and analyzable results.
Abstract: As networks of computing devices grow larger and more complex, the need for highly accurate and scalable network simulation technologies becomes critical. Despite the emergence of large-scale testbeds for network research, simulation still plays a vital role in terms of scalability (both in size and in experimental speed), reproducibility, rapid prototyping, and education. With simulation based studies, the approach can be studied in detail at varying scales, with varying data applications, varying field conditions, and will result in reproducible and analyzable results.
