TCP Traffic Based Performance Investigations of DSDV, DSR and AODV Routing Protocols for MANET Using NS2
Payal,Dr. Sudesh Kumar Jakhar
International Journal of Innovative Technology and Exploring Engineering , 2013,
Abstract: An Ad-hoc network is a dynamically changing network of mobile devices that communicate without the support of a fixed structure. TCP is a connection oriented transport protocol that provides reliable, in-order delivery of data to the TCP receiver. Hence, its use over Mobile Ad-Hoc networks is a certainty. This paper does the comprehensive investigations on routing protocols Dynamic Source Routing (DSR), Ad-hoc On demand distance vector (AODV) and Destination-Sequenced Distance-Vector (DSDV) using ns2 simulator considering TCP as transport protocol and FTP as traffic generator. Simulation results indicate that the performance of proactive routing protocol DSDV is far better than reactive routing protocols. DSR which uses source routing is the best among reactive routing protocols. It is observed that TCP is not appropriate transport protocol for highly mobile multihop wireless networks because TCP protocol is unable to manage efficiently the effects of mobility.

Abstract: Routing protocols play crucial role in determining performance parameters such as packetdelivery fraction, end to end (end 2 end) delay, packet loss etc. of any ad hoc communicationnetwork. In this paper the performance of DSDV protocol in sensor network of randomlydistributed static nodes with mobile source and sink nodes is investigated for source and sinkvelocities 0,10,20,40 and 60 m/sec. and node densities 20-100 nodes/km2 by ns-2 simulator. It isobserved that the average simulation end to end delay in static source and sink nodes scenario(i.e. velocity v=0) is generally higher than that in mobile source-sink cases for all node densitiesexcept at 20 nodes/km2. In the case where source and sink nodes are mobile, the delay is almostconstant at 0.12 seconds (except at v10 = 10 m/s for 40 nodes/km2). The average number ofdropped packets in static case is higher than that in dynamic source-sink scenario. With increasein the velocities in case of dynamic source and sink nodes, the average number of droppedpackets is around 10. The byte delivery fraction for moving source-sink cases for all velocities ishigher than that for the static case (i.e. v=0) for all node densities. The byte delivery fractiondecreases with the node density for all source-sink node velocities except velocity v=0.
Performance Analysis of Efficient and Geographic Multicast Routing Protocol for Mobile Adhoc Networks using NS-2  [PDF]

International Journal of Computer Technology and Applications , 2012,
Abstract: Group Communication has become important in Mobile Adhoc Network (MANET). But because of its dynamic topology it is difficult to implement group communication in MANET. In order to implement group communication, Efficient Geographic Multicasting Protocol (EGMP) came into existence, the efficiency and scalability of the protocol was already tested using Global Mobile Simulation (GloMoSim), but this paper test the Bandwidth utilization, performance and delay in packet transmission by using Network Simulator-2 (NS-2), as NS-2 helps in finding the functionality of the protocol in real time environment, at lower cost. In this EGMP uses a MAC layer protocol IEEE 802.15.4 SSCS with the data rate of 250kbps and the radio frequency 2.4GHz. Here a network wide Zone based bidirectional tree is constructed to achieve the efficient group membership management. Every node is aware of its own position which efficiently reduces the overhead for route searching and also comparing EGMP with AODV (Adhoc On-Demand Distance Vector Routing Protocol), EGMP has high Bandwidth utilization, lower delay in packet transmission, and higher performance. And EGMP has constant overhead irrespective of increase in number of nodes.

International Journal of Advances in Engineering and Technology , 2012,
Abstract: Vehicular ad-hoc network (VANET) is self-organizing wheeled networks that enable communication in between high speed moving road vehicles like cars, trucks, busses etc. in VANET network each vehicle behave as a mobile node and can be move in any direction with varying speeds that makes highly dynamic environment. The existing mobile ad-hoc network (MANET) routing protocol are unsuitable for VANET because of frequently change in mobility pattern and topology of this network. In last few years many ideas has come and implemented in this area but still there is scope of modernization. The reconstruction of existing protocol or introducing new idea of routing in VANET environment will be a milestone and the performance evaluation will be a nice approach towards that. In this paper we evaluate performance of AODV, DSDV and DSR routing protocol on the basis performance metric packet delivery ratio, end to end delay, and throughput of the network, in the cluster based VANET environment with increasing the number of mobile nodes. The Simulation studies are conducted using NS2.

International Journal on Computer Science and Engineering , 2009,
Abstract: A mobile ad-hoc network (MANET) is collection of intercommunicating mobile hosts forming a spontaneous network without using established network infrastructure. Unlike the cellular or infrastructure networks who have a wired backbone connecting the base-station, the MANETs have neither fixed routers nor fixed locations. Their performance largely depend upon the routing mechanism & nature of mobility. Earlier research hints that the Destination Sequenced Distance Vector (DSDV) routing protocol is one of the most efficient and popular protocols, as far as general parameters have been concerned.[1,6] We have experimentally evaluated, the performance metrics for network load, packet delivery fraction and end-to-end delay with DSDV Protocol using NS2 Simulator. This paper presents, the performance of DSDV protocol for four different mobility models namely: Random Waypoint, Reference Point Group Mobility, Gauss Markov & Manhattan Mobility Model having varying network load & speed. The experimental results suggest that DSDV protocol with RPGM mobility model has optimized results for varying network load and speed.

International Journal of Computer Science Issues , 2012,
Abstract: Mobile ad hoc network (MANET) is an organization of static and wireless mobile nodes having no any central administration and fixed infrastructure. In MANET, each node can acts as routing and hosting device. Performance comparison and analysis has been conducted by using four different scenarios in NS2 (Network Simulator) for which two reactive (AODV, DSR) and two proactive (OLSR, DSDV) ad hoc routing protocols have been selected by utilizing 802.11 wireless standard. The main goal is to find out the better performing protocol by measuring three metrics Packet Delivery Ratio, Throughput and Routing Overhead. As the results show that the performance of reactive protocols is better than proactive protocols.

Abstract: Wireless ad-hoc network is emerging network and form temporary networks. Due to its spontaneous nature the topology is frequently changes. Protocols selection and set up routing between any pair of nodes are the primary goal design for any wireless network. Several protocols are proposed in Mobile Ad-hoc Network (MANET) and selected protocol must provide best capability of data delivery and data integrity. In this paper, we are study and analysis the performance and characteristic of Ad-hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR), Optimized Link State Routing (OLSR) and Destination Sequenced Distance Vector (DSDV) protocols using NS2 simulator. We are comparing the above said protocols based on the delay, throughput, control overhead and packet delivery ratio.

Abstract: Ad Hoc on-Demand Distance Vector (AODV) Routing Protocol Performance Evaluation on Hybrid Ad Hoc Network: Comparison of Result of Ns-2 Simulation and Implementation on Testbed using PDA. In Mobile Ad hoc NETwork (MANET), node supplemented with wireless equipment has the capacity to manage and organise autonomously, without the presence of network infrastructures. Hybrid ad hoc network, enable several nodes to move freely (mobile) to create instant communication. Independent from infrastructure. They could access the Local Area Network (LAN) or the Internet. Functionalities of ad hoc network very much dependent on the routing protocol that determines the routing around node. Ad hoc On-demand Distance Vector (AODV) is one of routing protocols in ad hoc network which has a reactive characteristic. This protocol is the most common protocol being researched and used. In this Research, AODV protocol investigation was conducted by developing a testbed using Personal Computer, several Laptops (the Linux Red Hat operation system 9.0 and Fedora Core 2), and Personal Digital Assistant (PDA). This research also made a complete package by mean of cross compilation for PDA iPAQ. In general, results obtained from the simulation of AODV protocol using Network Simulator NS-2 are packet delivery ratio 99.89%, end-to-end delay of 0.14 seconds and routing overhead of 1,756.61 byte per second. Afterwards results from simulation were compared to results from testbed. Results obtained from testbed are as follows: the packet delivery ratio is 99.57%, the end-to-end delay is 1.004 seconds and the routing overhead is 1,360.36 byte per second.
