Simulation Study on Improved AODV Routing protocol

Mobile Ad-hoc Network (MANET) is a network of wireless mobile nodes which communicate with each other without any centralized control or established infrastructure. Routing is a critical task in MANET where the nodes are mobile. In this paper an attempt has been made to evaluate the performance of prominent routing protocol of MANET: Ad-hoc On-Demand Distance Vector Routing (AODV) and Improved Ad-hoc On-Demand Distance Vector Routing (I-AODV) protocol. The performance differentials are analysed using various metrics like throughput, average end-to-end delay, total bytes received and average jitter

Irregularity Behaviour Detection - Ad-hoc On-Demand Distance Vector Routing Protocol (IBD - AODV): A Novel Method for Determining Unusual Behaviour in Mobile Ad-hoc Networks (MANET)

All the communication in the mobile ad-hoc network (MANET) will depend on the intermediate neighbour nodes or router nodes. Routing protocol is very important in MANET, because all the communication will be done in the MANET depending on the neighbour or intermediate node. If the intermediate node is a malicious node, all the data will be lost or changed by the intermediate or malicious node. Ad-hoc On-demand Distance Vector routing protocol is one of the moderate routing protocol in MANET. The Ad-hoc On-demand Distance Vector Routing protocol does not have any security mechanism. This work is going to find the Irregularity Behaviour Detection (IBD) over the Ad-hoc On-Demand Distance Vector Routing (AODV) protocol. IBD is finding a trusted node by using the trust value (TV) of the node. This TV includes network performance, node energy level, and node position value. IBD-AODV is implemented and tested in the OmNetpp 6.0 simulator

Performance Analysis of Distributed Cache Invalidation Method in Mobile Ad hoc Networks using AODV and AOMDV Routing Protocols

Mobile Ad hoc Networks (MANETs) is an active wireless network that can be formed without any existing permanent framework networks. Mobile Ad hoc Networks is an independent structure of mobile nodes communicated with wireless channels. Distributed cache invalidation method is performed among intermediate routing mobile nodes. In MANETs routing protocols are provided desirable route establishments of the mobile nodes.

An Analysis of DSR, DSDV, AODV and Adv.-AODV Routing Protocols in MANET

A mobile Ad-Hoc network is a collection of autonomous wireless nodes without any fixed infrastructure and centralized administration. Mobile ad hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links. Each node operates not only as an end system, but also as a router to forward packets. The nodes are free to move about and organize themselves into a network. These nodes change position frequently. The main classes of routing protocols are Proactive, Reactive and Hybrid. A Reactive (on-demand) routing strategy is a popular routing category for wireless ad hoc routing The design follows the idea that each node tries to reduce routing overhead by sending routing packets whenever a communication is requested. In this paper, we evaluate the performance of reactive routing protocols, Ad hoc On demand Distance Vector (AODV) and Dynamic Source Routing (DSR) and proactive routing protocol Destination Sequenced Distance Vector (DSDV).The major goal of this study is to analyze the performance of well known MANETs routing protocol in high mobility case under low, medium and high density scenario. Unlike military applications, most of the other applications of MANETs require moderate to high mobility. In this paper, we evaluate the performance of reactive routing protocols, Advanced- Ad hoc On demand Distance Vector (Adv.-AODV), Ad hoc On demand Distance Vector (AODV) and Dynamic Source Routing (DSR) and proactive routing protocol Destination Sequenced Distance Vector (DSDV)[7][9].The major goal of this study is to analyze the performance of well known MANETs routing protocol in high mobility case under low, medium and high density scenario. Unlike military applications, most of the other applications of MANETs require moderate to high mobility. In this paper we analyzed the Adv.-AODV, AODV, DSDV and DSR protocols based on the performance metrics such as packet delivery ratio, average end to end delay and throughput in different test environments.

Performance Improvement in VANET by Modifying AODV Routing Protocol

A Vehicular Ad hoc network (VANET) is a type of peer-to-peer wireless network that allows providing communication between vehicles and nearby fixed roadside equipment. Vehicular ad hoc networks (VANETs) are classified as an application of Mobile Ad hoc Network (MANET)  that has the potential in improving road safety and in providing travellers comfort. In VANET due to fast vehicle movements the link topology changes rapidly hence lifetime of connection is short, hence dissemination of data is challenging in VANET and basic routing protocols cannot work efficiently. In this paper we improve the performance of Vehicular Ad-hoc Network (VANET) by modifying Ad-hoc On-demand Distance Vector (AODV) routing protocol, we compare proposed Improved Ad-hoc On-demand Distance Vector (IAODV) routing protocol with basic AODV protocol  in terms of network parameter Average End-to-End Delay. Keywords- AODV, Vehicular Ad hoc Network (VANET) , Improved AOD

Performance Analysis of MANET Routing Protocols - DSDV, DSR, AODV, AOMDV Using Ns-2

A Mobile Ad hoc Network (MANET) eliminates the complexity of an infrastructure configuration and allows wireless devices to communicate with each other independent of central infrastructure. It does not rely on a base station to coordinate the flow of messages to nodes in the network. A primary challenge for each device is to maintain the information to route traffic and data packets. Here, in our paper we analyze the performances of Destination Sequenced Distance Vector Routing (DSDV), Dynamic Source Routing (DSR), Ad hoc On-demand Distance Vector (AODV), Ad hoc On-demand Multi-path Distance Vector (AOMDV) protocols based on the Quality of Service metrics i.e., Packet Delivery Ratio, Packet Loss, Delay, Control Packet Overhead and Throughput using the Network Simulator (ns-2). In this paper we are presenting functionality, benefits, limitations and simulation results for the above mentioned routing protocols

A performance comparison of three wireless multi hop ad-hoc network routing protocols when streaming MPEG4 traffic

Mobile ad-hoc networks are characterised by constant topology changes, the absence of fixed infrastructure and lack of any centralised control. Traditional routing algorithms prove to be inefficient in such a changing environment. Ad-hoc routing protocols such as dynamic source routing (DSR), ad-hoc on-demand distance vector routing (AODV) and destination-sequence distance vector (DSDV) have been proposed to solve the multi hop routing problem in ad-hoc networks. Performance studies of these routing protocols have assumed constant bit rate (CBR) traffic. Real-time multimedia traffic generated by video-on demand and teleconferencing services are mostly variable bit rate (VBR) traffic. Most of these multimedia traffic is encoded using the MPEG standard. (ISO moving picture expert group). When video traffic is transferred over MANETs a series of performance issues arise. In this paper we present a performance comparison of three ad-hoc routing protocols - DSR, AODV and DSDV when streaming MPEG4 traffic. Simulation studies show that DSDV performs better than AODV and DSR. However all three protocols fail to provide good performance in large, highly mobile network environments. Further study is required to improve the performance of these protocols in mobile ad-hoc networks offering VBR services. <br /
