ABSTRACT
Mobile ad-hoc network (MANET) is an infrastructure less network, that is a collection of
mobile devices connected together without centralized infrastructure that can be configured at any
time and any where, it gives the network dynamic topology. The most important thing in MANETs is
a routing protocol. MANETs have a three major routing protocols proactive, reactive and hybrid. In
this work, the performance of reactive routing protocol Ad hoc on demand Distance Vector (AODV)
and proactive routing protocol Destination Sequenced Distance Vector (DSDV) for a health decision
support system (HDSS) were evaluated. The major goal of this work is to analyze the performance of
well-known MANETs routing protocol in mobility case under low, medium and high density
scenario. Hence it becomes important to study the performance of these routing protocols. The
performance is analyzed with respect to Average End-to-End Delay, drop packets, Packet Delivery
ratio (PDR) and Throughput. Simulation results verify that AODV gives better performance as
compared to DSDV.
Keywords: AODV, DSDV, HDSS, MANETs, NS2.
1. INTRODUCTION
Wireless networking is one of the technologies that users can access information and services
electronically. Wireless networks can be integrated with wired networks and can be classified in two
types [1].

1.1 Infrastructure Network
Infrastructure Network is a set of wireless devices that are connected to central device called
(base station), this base station control the communication between the devices as shown in Fig.1 ,
and if one device go out from range of the base station automatically will be connected with other
base station , this process is “called handoff”.
Figure.1: Infrastructure network
1.2 Ad-hoc Network
Ad-hoc network is an infrastructure less network defined as , the devices in a network can be
connected together directly without using any central device as shown in Fig.2, but the range in ad-
hoc network is limited , therefor the recent study focused on mobile ad-hoc networks (type of ad-hoc
network) using multi hope technology with support mobility to the nodes in network to enlarge the
coverage . The main challenge in MANETs , is the best selection of routing protocol to the network .
Integrating the MANET technology with the e-healthcare field is used in this work.
Figure.2: Mobile ad-hoc network
1.3 Routing Protocols
Mobile ad-hoc networks have many types of routing protocols. Fig.3 is a brief description of
it. Two types of routing protocols were studied in this work.

1.3.1 DSDV [DESTINATION SEQUENCE DISTANCE VECTOR]
DSDV is a proactive routing protocol based on the idea of the classical Bellman-Ford
Routing Algorithm. The main contribution of the algorithm was to solve the Routing Loop problem.
This protocol depend on table-driven means that every node in network maintain a routing table to
send data from source to destination. DSDV is a suitable routing protocol for ad-hoc network with
small number of nodes , but it has some disadvantage, that this protocol so effect in dynamically
change of network because it need regular update for the route path, addition to its performance is
not good with large number of nodes in the network[2] .

I 3 A 805
G 3 E 1050
E 2 F 1860
In Fig.4 and Table.1, Link between node A and node B was broken, for that node A search
for new path to connect with node T by its neighbors and select a new route path depend on less
number of hops and the last update for route table .

1.3.2 AODV [Ad-hoc On-demand distance vector]
AODV protocol is both an on-demand and a table-driven protocol discover routes only as
needed. AODV is a reactive protocol, although it still uses features of a proactive protocol. AODV
takes the interesting parts of DSR and DSDV, in concept of sequence numbers and sending of
periodic hello messages from DSDV and it uses the concept of route discovery and route
maintenance of DSR. The protocol uses different messages to discover and maintain links. When a
node desire to connect with another node, it checks if there is a valid route path to the destination,
the node use this route to connect with the destination node. If not valid , the source node send a
route request (RREQ) to its neighbor, if this neighbor has a route to the destination or it is a
destination ,it will reply (RREP) to the source node to send the data as shown in Figs.5,6 [3]. If there
is RERR receive by the source node that mean the source node go to discover a new path to the
destination.

Figure.6: Route Reply (RREP) propagation
1.4 Related work
To assess performance of routing protocol of MANETs Alice Abraham.et al.[4] presented a
detailed simulation of AODV and DSDV with different number of nodes and concluded that AODV
performance better than DSDV in throughput, end-2-end delay and PDR metrics. Also
M.A.SHABAD.et al.[5] gave comparison between AODVand DSDV and conclude that AODV
performs better in TCP networks for maintaining connection in network than DSDV. In case of drop
packet for comparison between DSDV and AODV Md. Shohidul Islam, Md. Naim Hider,
Md.TouhidulHaque and Letonmiah [6] conclude that DSDV performance is better than AODV.
Finally [2], [3] and [7] go to that AODV performance better from DSDV in many and different
situation.

2. PROPOSED NETWORK AND SIMULATION
For the simulation of the designed system, best version 2.34 of NS-2 has been used in this
work. Ns-2 is a discrete event simulator targeted at networking research. It began as a part of the real
network simulator and is evolving through an ongoing collaboration between the University of
California at Berkeley and the VINT project [8]. Network in this research deals with healthcare field,
that number of patients have a smart device, this device is designed to transmit the sensor data from
the patient to his doctor .Also this network has high scalability because at any time the network may
be have 20 patient and after few time the number of patient will be extend to be 80 or 120 for
example. This field was supported by MANETs technology that provide free mobility and free
wireless transmission of data by covering 1000m*1000m. Moreover this network can be extend to
larger area in this field.
Parameters of the designed network can be seen in Table.2 below.

3. METRICS CALCULATIONS
Four performance metrics were selected to compare the two routing protocols:-
1. Average End-to-End Delay
It is average of time taken by the data packets that propagate from source to destination
through a MANET. This includes all possible delays caused by buffering during routing
discovery latency, queuing at the interface queue, and retransmission delays at the MAC,
propagation and transfer times. Lower value of the end –to-end delay for better performance
of the protocol.
2. Packet Delivery Ratio (PDR)
It is a ratio of the number of data packets successfully delivered from the destinations to those
generated by sources.
Packet Delivery Ratio = received packets/sent packets * 100.
Higher value of the PDR for better performance of the protocol.

3. Throughput
It is the rate of successfully transmitted data packets in a unit time in the network during
the simulation. Higher value of the throu
4. Packet Loss
It is the total number of packets dropped by nodes dueto various reasons. The lower value of
the packet lost for better performance of the protocol.
Packet lost = No.of packet send

and DSDV on the basis of quantitative and qualitative metrics and also concentrate on common
issues of MANET used for a health decision support system. Based on the
health decision support system the scalability should be considered which may some times vary in
number of nodes (20 -120), for that
AODV gives better performance for three o
and PDR.

The most important thing in MANETs is a routing protocol. MANETs have a three major routing protocols proactive, reactive and hybrid. In this work, the performance of reactive routing protocol Ad hoc on demand Distance Vector (AODV) and proactive routing protocol Destination Sequenced Distance Vector (DSDV) for a health decision support system (HDSS) were evaluated. The major goal of this work is to analyze the performance of well-known MANETs routing protocol in mobility case under low, medium and high density scenario. Hence it becomes important to study the performance of these routing protocols. The performance is analyzed with respect to Average End-to-End Delay, drop packets, Packet Delivery ratio (PDR) and Throughput. Simulation results verify that AODV gives better performance as compared to DSDV. Keywords: AODV, DSDV, HDSS, MANETs, NS2. 1. INTRODUCTION Wireless networking is one of the technologies that users can access information and services electronically. Wireless networks can be integrated with wired networks and can be classified in two types [1].

Figure.1: Infrastructure network 1.2 Ad-hoc Network Ad-hoc network is an infrastructure less network defined as , the devices in a network can be connected together directly without using any central device as shown in Fig.2, but the range in ad- hoc network is limited , therefor the recent study focused on mobile ad-hoc networks (type of ad-hoc network) using multi hope technology with support mobility to the nodes in network to enlarge the coverage . The main challenge in MANETs , is the best selection of routing protocol to the network . Integrating the MANET technology with the e-healthcare field is used in this work. Figure.2: Mobile ad-hoc network 1.3 Routing Protocols Mobile ad-hoc networks have many types of routing protocols. Fig.3 is a brief description of it. Two types of routing protocols were studied in this work.

The main contribution of the algorithm was to solve the Routing Loop problem. This protocol depend on table-driven means that every node in network maintain a routing table to send data from source to destination. DSDV is a suitable routing protocol for ad-hoc network with small number of nodes , but it has some disadvantage, that this protocol so effect in dynamically change of network because it need regular update for the route path, addition to its performance is not good with large number of nodes in the network[2] . Figure.4: Creation new route path for node A Table.1: Route Path Update Neighbor Hop number Via node Update Time C 2 H 1756 I 3 A 805 G 3 E 1050 E 2 F 1860 In Fig.4 and Table.1, Link between node A and node B was broken, for that node A search for new path to connect with node T by its neighbors and select a new route path depend on less number of hops and the last update for route table .

AODV is a reactive protocol, although it still uses features of a proactive protocol. AODV takes the interesting parts of DSR and DSDV, in concept of sequence numbers and sending of periodic hello messages from DSDV and it uses the concept of route discovery and route maintenance of DSR. The protocol uses different messages to discover and maintain links. When a node desire to connect with another node, it checks if there is a valid route path to the destination, the node use this route to connect with the destination node. If not valid , the source node send a route request (RREQ) to its neighbor, if this neighbor has a route to the destination or it is a destination ,it will reply (RREP) to the source node to send the data as shown in Figs.5,6 [3]. If there is RERR receive by the source node that mean the source node go to discover a new path to the destination. Figure.5: Route Request (RREQ) flooding Figure.6: Route Reply (RREP) propagation 1.4 Related work To assess performance of routing protocol of MANETs Alice Abraham.et al.[4] presented a detailed simulation of AODV and DSDV with different number of nodes and concluded that AODV performance better than DSDV in throughput, end-2-end delay and PDR metrics. Also M.A.SHABAD.et al.[5] gave comparison between AODVand DSDV and conclude that AODV performs better in TCP networks for maintaining connection in network than DSDV. In case of drop packet for comparison between DSDV and AODV Md. Shohidul Islam, Md. Naim Hider, Md.TouhidulHaque and Letonmiah [6] conclude that DSDV performance is better than AODV. Finally [2], [3] and [7] go to that AODV performance better from DSDV in many and different situation.

PROPOSED NETWORK AND SIMULATION For the simulation of the designed system, best version 2.34 of NS-2 has been used in this work. Ns-2 is a discrete event simulator targeted at networking research. It began as a part of the real network simulator and is evolving through an ongoing collaboration between the University of California at Berkeley and the VINT project [8]. Network in this research deals with healthcare field, that number of patients have a smart device, this device is designed to transmit the sensor data from the patient to his doctor .Also this network has high scalability because at any time the network may be have 20 patient and after few time the number of patient will be extend to be 80 or 120 for example. This field was supported by MANETs technology that provide free mobility and free wireless transmission of data by covering 1000m*1000m. Moreover this network can be extend to larger area in this field. Parameters of the designed network can be seen in Table.2 below.

METRICS CALCULATIONS Four performance metrics were selected to compare the two routing protocols:- 1. Average End-to-End Delay It is average of time taken by the data packets that propagate from source to destination through a MANET. This includes all possible delays caused by buffering during routing discovery latency, queuing at the interface queue, and retransmission delays at the MAC, propagation and transfer times. Lower value of the end –to-end delay for better performance of the protocol. 2. Packet Delivery Ratio (PDR) It is a ratio of the number of data packets successfully delivered from the destinations to those generated by sources. Packet Delivery Ratio = received packets/sent packets * 100. Higher value of the PDR for better performance of the protocol.
