This document analyzes the performance of different routing protocols (AODV, DSR, DSDV) under various mobility models (random waypoint, random direction, random walk) and node speeds in mobile ad hoc networks. It finds that reactive protocols like AODV and DSR generally have higher packet delivery ratios than proactive DSDV, but end-to-end delays vary depending on the mobility model and node speed. The document proposes an algorithm to select the best routing protocol based on whether data delivery or time is the higher priority, and whether nodes are stationary or mobile. DSDV is preferred when data delivery is most important, while DSR performs better for time-critical applications.
Survey of Modified Routing Protocols for Mobile Ad-hoc Networkijsrd.com
In last few years extensive research work has been done in the field of routing protocols for Ad-hoc Network. Various routing protocols have been evaluated in different network conditions using different performance metrics. A lot of research has been done how to modify standard routing protocol in ad-hoc network to improve its performance. The hop count is not only metric that gives efficient routing path. There are various modified protocols which make the use of other parameters along with hop count to select the best routing path to the destination. In standard Ad-hoc On-demand Distance Vector (AODV) routing protocol only hop count is used for selecting the routing path. In this paper we have studied variants of AODV protocols with modified routing metric.
Mobility is one of the basic features that define an ad hoc network, an asset that leaves the field free for the
nodes to move. The most important aspect of this kind of network turns into a great disadvantage when it
comes to commercial applications, take as an example: the automotive networks that allow communication
between a groups of vehicles. The ad hoc on-demand distance vector (AODV) routing protocol, designed
for mobile ad hoc networks, has two main functions. First, it enables route establishment between a source
and a destination node by initiating a route discovery process. Second, it maintains the active routes, which
means finding alternative routes in a case of a link failure and deleting routes when they are no longer
desired. In a highly mobile network those are demanding tasks to be performed efficiently and accurately.
In this paper, we focused in the first point to enhance the local decision of each node in the network by the
quantification of the mobility of their neighbours. Quantification is made around RSSI algorithm a well
known distance estimation method.

One question that arises is whether speed of nodes affects the relative performance of routing protocols being studied. This paper addresses the question by simulating two routing protocols AODV and DSDV. Protocols were simulated using the ns-2 and were compared in terms of packet delivery fraction, normalized routing load and average delay, while varying number of nodes, and speed.

Abstract: In the last couple of years, the use of wireless networks has become more and more popular. A
MANET is a collection of self-organizing mobile nodes which is infrastructure less, autonomous, and standalone
networks. Each node in a MANET is free to move independently in any direction and will therefore change its
links to other devices frequently. Each must forward traffic unrelated to its own use and therefore be a router.
Simulation result has been obtained by a performance comparison of three routing protocols i.e. Ad hoc Ondemand
Distance Vector (AODV), Dynamic Source Routing (DSR), Location Aided Routing (LAR1) against
Simulation time. The Result is obtained using QualNet simulator version 6.1. Different protocols are evaluated
based on measures such as Average End to End delay (s), Average Jitter(s), and Packet delivery ratio.

ENERGY AND PERFORMANCE EVALUATION OF REACTIVE, PROACTIVE, AND HYBRID ROUTING ...ijwmn
This paper evaluates the energy consumption of well-known routing protocols, along with other metrics
such as throughput, packet delivery ratio (PDR), and delay in different scenarios. We consider two other
metrics in order to capture the efficiency of the energy consumption: e-throughput which is the ratio
between the consumed energy and the throughput; and the e-PDR which is the ratio between the
consumed energy and the PDR. We compare four routing protocols: AODV, OLSR, and HWMP in
Reactive and Proactive modes. The number of nodes is varying between 25 and 81 nodes, with different
mobility models. Simulations are conducted using NS3 and the parameters of a real network interface
card. From the results, AODV presents the lowest energy consumption and a better e-Throughput. OLSR
provides a better e-PDR in mobile scenarios. With a smaller e-PDR and e-Throughput, the proactive
mode of HWMP is more energy efficient than the reactive mode.
Comparative Analysis of MANET Routing Protocols and Cluster Head Selection Te...IJERA Editor
Mobile Ad-hoc Network is a kind of wireless network. It is a backbone of new generation advanced communication technology. MANET is an ideal applicant for rescue and emergency situation due to its independence of connected devices of fixed wires. This paper represents a work on trust based system in MANET cluster that can be used to improve the performance of the network even in the existence of not trusted nodes. In the cluster architecture, cluster head and gateway nodes form a communication for routing among neighbouring clusters. But selection of cluster head is the important problem in dynamic Ad-hoc network because cluster head work as coordinator in clustered architecture. In this work, some values have used correspond to the threshold values of forward packet and dropped packet of each node within the network cluster. These values have been used dynamically updated every time and the node is selected as cluster head. In this technique of selecting the node as cluster head, the node which has maximum trusted value is elected as cluster head and this information is updated in every node’s trusted table. After implementation of our desired work, the proposed Dynamic Trust Evaluation of Cluster Head (DTE-CH) technique is analysed with traditional routing protocols and traditional clustering technique viz. Highest Degree Algorithm. The simulation is done by using network simulator software on the basis of different performance metrics throughput, packet delivery ratio, routing overhead, packet drop, average end to end delay and remain energy. Simulation result presents that proposed DTE-CH technique improves the performance of network as compare to most suitable existing AODV MANET protocol based technique as well as traditional highest degree clustering technique.

A Survey of Enhanced Routing Protocols for Manetspijans
Mobile Ad Hoc Networks (MANETs) form a class of dynamic multi-hop networks consisting of a set of
mobile nodes that intercommunicate on shared wireless channels. MANETs are self-organizing and selfconfiguring multi-hop wireless networks, where the network structure changes dynamically due to the node
mobility. There exists no fixed topology due to the mobility of nodes, interference, multipath propagation
and path loss. Hence efficient dynamic routing protocols are required for these networks to function
properly. Many routing protocols have been developed to accomplish this task. In this paper we survey
various new routing protocols that have been developed as extensions or advanced versions of previously
existing routing protocols for MANETs such as DSR, AODV, OLSR etc.

A Mobile Ad hoc NETwork (MANET), is a self-configuring infra structure less network of mobile devices
connected by wireless links. ad hoc is Latin and means "for this purpose". Each device in a MANET is free
to move independently in any direction, and will therefore change its links to other devices frequently. Each
must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building
a MANET is equipping each device to continuously maintain the information required to properly route
traffic. QOS is defined as a set of service requirements to be met by the network while transporting a
packet stream from source to destination. Intrinsic to the notion of QOS is an agreement or a guarantee by
the network to provide a set of measurable pre-specified service attributes to the user in terms of delay,
jitter, available bandwidth, packet loss, and so on. The analysis is mainly between proactive or table-driven
protocols like OLSR (Optimized Link State Routing) viz DSDV (Destination Sequenced Distance Vector) &
CGSR (Cluster Head Gateway Switch Routing) and reactive or source initiated routing protocols viz
AODV (Ad hoc on Demand distance Vector) & DSR (Dynamic Source Routing). The QoS analysis of the
above said protocols is simulated on NS2 and results are shown thereby.

Performance Comparison and Analysis of Table-Driven and On-Demand Routing Pro...Narendra Singh Yadav
Mobile ad hoc network is a collection of mobile nodes communicating through wireless channels without any existing network infrastructure or centralized administration. Because of the limited transmission range of wireless network interfaces, multiple "hops" may be needed to exchange data across the network. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. The primary goal of such an ad hoc network routing protocol is correct and efficient route establishment between a pair of nodes so that messages may be delivered in a timely manner. Route construction should be done with a minimum of overhead and bandwidth consumption. This paper examines two routing protocols for mobile ad hoc networks– the Destination Sequenced Distance Vector (DSDV), the table- driven protocol and the Ad hoc On- Demand Distance Vector routing (AODV), an On –Demand protocol and evaluates both protocols based on packet delivery fraction, normalized routing load, average delay and throughput while varying number of nodes, speed and pause time.
Analysis of Random Based Mobility Model using TCP Traffic for AODV and DSDV M...ijsrd.com
In Mobile Ad hoc network (MANETS), no fixed infrastructure is available. Different wireless hosts are free to move from one location to another without any centralized administration, so, the topology changes rapidly or unpredictably. Every node operates as router as well as an end system. Routing in MANETs has been a challenging task ever since the wireless networks came into existence. The major reason for this is continues changes in network topology because of high degree of node mobility. The MANET routing protocols have mainly two classes: Proactive routing (or table-driven routing) protocols and Reactive routing (or on-demand routing) protocols. In this paper, we have analyzed various Random based mobility models: Random Waypoint model, Random Walk model, Random Direction model and Probabilistic Random Walk model using AODV and DSDV protocols in Network Simulator (NS 2.35). The performance comparison of MANET mobility models have been analyzed by varying number of nodes using traffic TCP. The comparative conclusions are drawn on the basis of various performance metrics such as: Routing Overhead (packets), Packet Delivery Fraction (%), Normalized Routing Load, Average End-to-End Delay (milliseconds) and Packet Loss (%).

Each node in MANET operates as a router, forwarding information packets for other mobile nodes. There are many routing protocols that
possess different performance levels in different scenarios. The main task is to evaluate the existing routing protocols and finding by comparing them the best one. In this article we compare AODV, DSR, DSDV, OLSR and DYMO routing protocols in mobile ad hoc networks (MANETs) to specify the best operational conditions for each MANETs protocol. We study these five MANETs routing protocols by different
simulations in NS-2 simulator. We describe that pause time parameter affect their performance. This performance analysis is measured in terms of Packet Delivery Ratio, Average End-to-End Delay, Normalized Routing Load and Average Throughput.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Abstract: A mobile ad-hoc network is a continuously self-configuring, infrastructure less, network of mobile
devices. It is the network of mobile nodes without any fixed topology. In this network, each node acts as both
hosts and router simultaneously. Each device in a MANET is free to move independently in any direction, and
will therefore change its link to other devices frequently. In such a network there are lots of possibilities of
mobility of nodes. Therefore mobility of nodes is challenging issue for designer. We have surveyed comparative
performance analysis of different routing protocols. Under the different mobility models in term of Packet
Delivery Ratio, Average End to End Delay. We have carefully studied the behavior of these routing protocols
and compared their performance in different scenarios based. This paper defines which protocol to use in
different cases such as if time is important or if data is important in various mobility modes such as all node
mobility, destination node mobility and source node mobility and proposed the new algorithm on the basis of
protocols evaluation in different situation.
1. INTRODUCTION
Nodes in the network may be able to communicate
directly with each other, for example when they are
within wireless transmission range of each other.
However, ad hoc networks must also support
communication between nodes that are indirectly
connected by a series of wireless hops through other
nodes. Routing is well studied feature of such
networks because mobile nodes may move in various
directions, which can cause existing link to break and
the establishment of new routes.
A good routing protocol should minimize the
computing load on the host as well as the traffic
overhead on the network . There are three types of
routing protocol in Mobile Ad-Hoc Networks
Proactive (Table Driven) routing protocol, Reactive
(Demand Driven) routing protocol and Hybrid
Routing Protocol[2]. Routing protocol is use to find
the route between communication nodes. A mobility
model is representing the movement behavior of
mobile node.
2. EXISTING WORK
2.1 MANET Routing Protocols
Proactive routing protocol provide a fast response to
topology change continuously monitoring topology
change and disseminating the related information as
needed over the network. However rapid response to
topology changes is the increase in routing overhead,
and this can lead to smaller packet delivery ratio and
longer delay when topology changes increase.
Reactive routing protocols form a route if needed and
reduce the routing overhead. However the long setup
time in route discovery and slow response to route
changes can offset the benefit derived from on
demand and lead inferior performance.
2.1.1 Table-driven protocols
These protocols have their ability to maintain routing
tables that store information regarding the routes from
one node in the network to the rest of other nodes.
Here, all nodes update their tables to preserve
compatibility by exchanging routing information
between the participating nodes. When the topology
of the network changes, the nodes distribute update
messages across the network. These protocols may be
easy to implement, but the major limitation is that,
due to the inherently highly mobile and dynamic
nature of ad-hoc networks, the maintenance of routing
information in these tables is challenging.
• DSDV (Destination-Sequenced Distance –Vector
Routing Protocol)
This protocol is based on the Bellman-Ford classical
routing mechanism. Here each mobile node maintains
a routing table that includes all accessible
destinations, the number of hops necessary for
reaching that destination and the sequence of the
digits appropriate to that destination. Routing table
entries are tagged with sequence of digits which are
originated by the destination nodes. This sequence of
digits is used to distinguish new routes from old
routes and also to determine the creation of a ring.
Route updates are transmitted either periodically or
immediately after a significant topology change is
being detected. DSDV protocol generates a
supplementary traffic that adds to the real data traffic.
2.1.2 Reactive (On Demand) Routing Protocol
These types of routing protocols create routes only
when desired by the source node. When a source node

requires route it initiates a route discovery process to
find the route to the destination. This type of protocols
find route by flooding the network with route request
packet. This process is completed once a route is
found or all possible route permutations have been
examined. Once a route has been established, it is
maintain by a route maintain procedure. Then this
route is used for further communication.
AODV (Ad-Hoc On Demand Distance Vector
Routing)
AODV does not attempt to maintain routes from
every node to every other node in the network. It only
require route when necessary and do not need
maintain route that are not use currently. When a
source node need route to certain destination, It
broadcast a route request (RREQ) packet to all other
neighbors. This packet contains a IP address and
sequence number as well as the destination IP address
and last known sequence number. The RREQ also
contain the broadcast ID. When a node receives a
RREQ it first checks IP address and broadcast ID. If it
has already seen a RREQ with same IP address and
broadcast ID then discard the packet otherwise
rebroadcast the packet. Once the RREQ reaches the
destination node respond by unicast a route reply
(RREP) to the source. This route is use for
communication between sources to destination.
DSR (Dynamic Source Routing)
The DSR is an on-demand routing protocol. The DSR
routing protocol consists of two major phase’s route
discovery and route maintenance. When a source nose
S want to sand a packet to destination D. It establish a
route from S to D this phase is called route discovery.
Route discovery use only when no route between
source to destination. Second phase route
maintenance phase requires in case of route failure, it
involve another route to destination. Then the source
S can be use an alternate route to destination D, if it
known one, or invoke route discovery.
2.2 Mobility Models
Mobility Models describes how speed, acceleration
and direction of the node change over time .
2.2.1 Random Waypoint Mobility Model
The Random Waypoint Mobility Model is the most
common mobility model used in MANET researches.
The RWP model is random model for movement of
mobile use, how their location, velocity and
acceleration change over time. A mobile node begins
the simulation by waiting a specified pause time.
After this pause time it selects a random direction and
random speed between 0 m/sec to Vmax m/sec in the
network area. After reaching this destination node
wait again pause time and then select a new direction
and speed for movement . The node keeps moving
until reaches its direction at that speed. If a node
selects a far destination and low speed travels for a
long time. AODV performs better than DSR and
DSDV in random waypoint mobility model [1].
AODV gives the better packet delivery ratio[1]. The
overall performance of AODV is better in random
waypoint mobility model[1].
2.2.2 Random Direction Mobility Model
In Random Direction the mobile node select a
direction travel to the border of the network area. On
reaching the boundary it wait for a specific pause time
and then
choose the new direction to follow . This model
does not suffer from the density waves in the centre of
the simulation space that Random Waypoint Model
does. For the Random Waypoint Mobility Model the
probability of choosing a location near center is very
high.
2.2.3 Random Walk Mobility Model
It is a simple mobility model based on random
direction and speed. In this mobility model mobile
node choose a random direction and speed for
movement. The new direction and speed choose from
predefined ranges. On reaching the boundary of
simulation area the node reflect back with an angle
determined by incoming direction.
3. SYSTEM IMPLEMENTATION AND
DISCUSSION
3.1 Performance Metrics
To evaluate the performance of AODV, DSR,
DSDV routing protocols two performance metrics
Packet Delivery Ratio(PDR) Average end to end
delay[3] by varying the speed of mobile nodes are
considered
A. Packet Delivery Ratio
PDR = ( packet receives / packet sent )
B. Average End to End delay
It includes delay caused by latency,
buffering, queuing, transmission and route discovery
The given table 1 represents the Evaluation of
protocols in different mobility model with varying
speed of nodes [1]

Table1: Comparison of AODV, DSR and DSDV
Protocol using Different Mobility Models.
Packet Delivery Ratio
In all three protocols PDR is decreases linearly
with increasing the speed of nodes[1].
PDR for reactive routing protocols AODV and
DSR were better than the proactive DSDV[1].
From two reactive routing protocols AODV and
DSR , AODV gives slightly more PDR than
DSR[1].
A. Average end to end delay
For all three protocols average end to end delay
increases as the speed of node increases[1].
In Random Waypoint mobility model end to
end delay is high for DSDV and low for DSR[1]
.
In Random Walk mobility model end to end
delay is high for AODV and low for DSDV up to
certain limit of speed then it increases and lowest
end to end delay is given by DSR[1].
In Random Direction mobility model end to end
delay is high for AODV and low for DSR[1].
AODV performs better than DSR and DSDV in
Random waypoint mobility model[1].
In random waypoint and random direction as the
speed of node increases the packet delivery ratio
of DSR decreases with high degree respect to the
AODV and DSDV[1].
The overall performance of AODV is better in
random waypoint mobility model[1].
In the random walk and random direction models
the end to end delay is very high for AODV than
DSR and DSDV protocols. If the speed of node is
10m/sec then the AODV perform better but if we
increase the speed up to 40m/sec performance of
AODV decrease because end to end delay is very
high[1].
The packet delivery ratio is high of AODV in
random walk and random direction, but the end to
end delay was also very high for AODV
protocol[1].
So the overall performance of DSR is better than
the AODV and DSDV in random walk and random
direction mobility model[1].
4. PROPOSED WORK
Sometimes it is important to deliver data from source to
destination in time in such a case some form of data
loss is tolerable and many time it is important to
deliver data without any loss but some form of time
delay not matters in such a cases. Putting such
conditions in front, study of two protocols DSR and
DSDV gives solution for such cases. The metrics
Packet Delivery Ratio and End to End Delay are
important here. More packet delivery ratio means less
packet lost during transmission and end to end delay
indicate total delay for packet.

Description –
Here network of 10 nodes is considered. In the
network one node is source node, one is destination
node and all other nodes are intermediate nodes act as
a router in MANET to deliver the data from source
node to destination node. Protocols taken are DSR
and DSDV. For evaluation purpose performance
metrics such as throughput and average end to end
delay are considered. In such case three mobility
modes are possible. First mode is when only source
node in the network is mobile. In second mode only
destination mode in the network is mobile. In third
mode all the nodes of the network are mobile.
Impacts of these modes on the performance of
protocols are as follows.
When all the nodes in the network are mobile then it
is DSDV gives high packet delivery ratio than DSR,
but average end to end delay is less in DSR. So, it is

concluded that for user if data is important than time
then it is good to use DSDV. If time is important then
use DSR. If destination node in the network is mobile
and all other are non-mobile then DSDV gives more
packet delivery ratio than DSR but average end to end
delay is less in DSR. So, if data is important use
DSDV otherwise DSR. If source node in the network
is mobile then DSR is of no use.
5. CONCLUSION AND FUTURE WORK
This paper determines which protocol to use
in different cases. When Data is important and all the
nodes in the network are mobile then use DSDV
otherwise if time is important factor then use DSR.
When data is important and only destination node is
mobile then use DSDV otherwise if time is important
then use DSR. If source node only is mobile then use
only DSDV. The proposed algorithm is very useful
for researcher to check the performance of different
protocols under different mobility models without
checking each case using NS2.
Future work will be to evaluate the performance of
various new protocols or modified version of these
protocols could also be compared.
