Abstract: The mobile ad hoc network is the self-configuring network in which mobile nodes can change their location any time. Due to

its decentralized nature, routing is the major issue of this network. The routing protocols are used to establish secure and efficient path

from source to destination. The routing protocols are broadly classified into reactive, proactive and hybrid. In this paper, the AODV and

DSR routing protocols are compared in terms of various parameters and it has been analyzed that AODV performs better in all the

aspects.

Keywords: AODV, DSR, Delay, Throughput, Packet loss.

I. INTRODUCTION

A robust infrastructure less wireless network which involves

the communication between both fixed as well as mobile

nodes is known as Mobile Ad Hoc network. There are various

arbitrary topologies created due to the random connection of

the nodes. They act either as routers or as hosts and can also

configure themselves which can thus increase the usage of this

technique within various applications. Mainly the applications

which cannot have any communication infrastructure and

might include emergency situations and rescue operations

such as disaster-prone areas need such type of network

infrastructures within them [1]. There are both static as well

dynamic topologies involved within the MANET routing

protocols. There are no centralized or fixed infrastructures

present within the ad hoc networks. This leads to various

challenges arising within the functionality of these networks

and to avoid this, the MANETs are introduced within the

wireless ad hoc networks [2]. The traffic received from the

intermediate nodes is accepted and routed towards the

destination within this network. This means that is can be

represented as a router as well as a host. The energy

constraints present on the mobile nodes are the most

prominent ways which can deplete the connections amongst

the nodes. The communication amongst the nodes with the

help of routers is done through the routing protocols present

within the network [3]. The exchange of information amongst

the intermediate nodes is done within the complete network.

The shortest route from source end to the destination end is to

be identified for providing an efficient communication within

the network which can be done through these routing

protocols [4]. A list that comprises of the fresh routes as well

as their distance from the source node is held within the

proactive routing protocols. The protocol which is based on

the classical Bellman-Ford Routing Algorithm ideology along

with its own enhancements and is table-driven is known as the

DSDV routing protocol [5]. A lazy approach which does not

contain the complete information of all the nodes present

within the network and is on-demand based is known as the

reactive protocol.

a. Ad hoc On-demand Distance Vector: An on-demand

routing protocol which easily adapts the changes occurring in

the conditions of the connections amongst the nodes is known

as the AODV routing protocol [6]. In the conditions where

link failure occurs, the message is transferred to the nodes that

are affected due to it.

b. Dynamic Source Routing: A reactive routing protocol

which comprises of the ad hoc wireless networks and includes

on-demand features is known as the DSR protocol [7].

However, this protocol is not table-driven although it includes

on-demand features like AODV. On the basis of source

routing, this protocol is deployed.

II. LITERATURE REVIEW

Er. Rubia Singla, Er. Jasvir Singh explained [8] that there

are various types of link failures occurring within the mobile

ad-hoc network. A node-disjoint multipath routing which is

based on AOMDV protocol is implemented in this paper. The

objective here is to gather all the accessible node-disjoint

routes that have least routing control overhead from source to

destination. It is seen through the simulation results that in

terms of various parameters the effectiveness of the proposed

method increases.

Laxman H. Sahasrabuddhe and Biswanath Mukherjee [9]

proposed in this paper that there are many multicast

applications present within the network which are to be

however made efficient enough to be used in the other various

communication modes. The optimization of one property of a

simple multicast tree is the main focus of almost all the

literatures present in the paper, so on the basis of that the

enhancement of the property is to be done. Without much

costing efforts, the enhancements are made within the

algorithm and the results are evaluated.

Mahesh K Marina and Samir R Das proposed [10] in this

paper the multipath extensions which are related to the single

path routing protocol which is known as ad hoc on-demand

distance vector (AODV) protocol which is further known as

AOMDV protocol. The performance analysis is done in NS2

simulator and the outcomes depict that the packetloss is

minimized by 40%. There is also a huge change in the end-to-

end delay within the network. Along with these advantages,

the routing overhead within the network is also reduced by

30% which is mainly done by minimizing the frequency of

route discovery process with the help of AOMDV routing

protocol.

Mina Vajed Khiavi and Shahram Jamali they explained

[11] about the main challenges of Mobile Ad Hoc Networks

is the design of robust routing algorithms that adapt to the

frequent and randomly changing network topology. In this

paper they compare AODV and AOMDV routing protocols

for MANETs. The AODV is a unipath routing protocol and

AOMDV is a multipath version of AODV. Performance of

AODV and AOMDV is evaluated based on Packet Delivery

Ratio, Network Life Time, System Life Time and End –to-

End Delay.

P. Periyasamy and E. Karthikeyan, they explained [12] that

the interconnection of mobile devices with the help of

wireless links is known as mobile ad hoc network. This

network consists of a dynamic topology. For transmitting

information within the network, the routing protocols play a

very important role. Unipath and multipath are the two

broader classifications amongst the routing protocols. The

performance of the commonly utilized AOMDV routing

protocol is proposed in this paper. Two different traffic

patterns are also involved here on which there patterns are

present and the results are provided.

Shancang Li [13] proposed in this paper that for developing

the new applications in a quick manner a flexible design needs

to be presented. For providing Quality of Service (QoS)

within various applications the already existing multipath

routing methods have also been studied which show the

effectiveness of traffic distribution across multipaths within

the network. This adaptive as well as secure load-balancing

routing mechanism is analyzed through various experiments

and the simulation results provided show the performance of

this proposed method.

III. EXPERIMENT RESULTS

In this work, the simulation is performed in NS2 and the most

efficient protocols which are DSR and AODV are compared.

Figure 1: Packet loss graph

As illustrated in figure 1, due to broadcast nature of AODV

protocol the packet loss is high in the network. The proposed

technique will maintain multicasting tree which leads to

reduction in network packet loss.

Figure 2: Throughput graph

As shown in figure 2, the network throughput is high as

compared to existing broadcasting nature protocol. Due to

high bandwidth consumption of existing technique leads to

reduction in throughput. In the multicasting technique

bandwidth consumption is less which leads to improvement

in network throughput.

Figure 3: Delay graph

As shown in figure 3, the delay in the proposed technique is

less as compared to existing technique. This is due to less

bandwidth consumption is proposed technique.

IV. CONCLUSION

In this work, it has been concluded that mobile ad hoc network

is the decentralized network due to which routing issue may

arise which reduces the network performance. For the

efficient routing, routing protocols came into existence which

are classified into reactive, proactive and hybrid. In this paper,

the comparative analysis of AODV and DSR routing

protocols is done and has been concluded that AODV protocol

is better than DSR with respect to various parameters.
