2. BROAD AREA
• Networks
Network is a collection of hardware
components and computers interconnected by
communication channels that allow sharing of
resources and information.
• Network Security
Network security consists of provisions and
policies adopted by the network administrator to
prevent and monitor unauthorized access, misuse,
modification and network accessible resources.

3. SPECIFIC AREA
MANET
The MANET(Mobile Adhoc Networks) is a self-
configuring infrastructureless networks of mobile
devices connected by wireless links.
Flooding Attack
The flooding attack is an attack that attempts to
cause a failure in a computer system or other data
processing entity by providing more input than entry
can process properly.

6. NOVEL DEFENSE MECHANISM AGAINST DATAFLOODING
ATTACKS IN WIRELESS AD-HOC NETWORKS(2010)
Methodology
The Period Based Defense Mechanism (PDM) is used here,
& is used to enhancing the throughput of burst traffic.
Advantage
It can guarantee the Quality of Service (QoS) of burst
traffic.
Drawback
When the number of packets per second is high (burst
traffic), AODV cannot process packets because of the
resource exhaustion.

7. FLOODING ATTACKS PREVENTION IN MANET(2011)
Methodology
Flooding Attack Prevention (FAP) has been developed,
where FAP refers a defense system against the Ad Hoc
Flooding Attack.
It analyse the behaviour of intruder and check it by trust
function.
Advantage
In FAP, the neighbors are categorized into friends (most
trusted), acquaintances (trusted) and strangers(not trusted).
Therefore it is easily identified.
Drawback
The Problem is it doesn’t work properly with HIGHER

PERFORMANCE ANALYSIS OF MOBILE AD HOC NETWORKS
UNDER FLOODING ATTACKS (2011)
Methodology
The influence of flooding attack on the entire network
performance is analyzed under the circumstances of
different parameters including
i. Number of attack nodes
ii. Flooding frequency
iii.Network bandwidth
iv.Number of normal nodes.
Advantage
When the number of flooding packets occurs in NIC’s
processing power, most of the packets in the queue are
8 September 14, 2012
discarded.
9. Drawback
When the frequency of flooding increases, the packet
delays occurs.
when network resources have been exhausted, with the
increasing frequency of flooding attacks, It results in the
loss of packets with long routes .

HELLO FLOOD ATTACK AND ITS COUNTERMEASURES IN
WIRELESS SENSOR NETWORKS (2010)
Methodology
The proposed security framework for hello flood detection
via
A signal strength method
A client puzzle method
Advantage
The Accuracy will be considerly improved, leading to
better understanding and forecasting such phenomena.
Drawback
In these methods, When the node doesn’t receive any
reply message in a predefined time, it treats sender as a
10 attacker. September 14, 2012
11. A
TRUST BASED SECURITY SCHEME FOR RREQ FLOODING
ATTACK IN MANET (2010)
Methodology
The Distributive approach has been proposed to detect and
prevent the RREQ flooding attack.
The effectiveness of the proposed technique depends on
the selection of threshold values.
Advantage
When the node identifies that sender is originating
dataflooding, it cutt off the path & send error message.
Drawback
It get delays to detect the misbehaving node by allowing
him to sends more packet until timeout occurs.

12. PERFORMANCE ANALYSIS OF FLOODING ATTACK
PREVENTION ALGORITHM IN MANETS (2009)
Methodology
The performance of trust algorithm is used to test the
adhoc networks to implementing the AODV protocol.
Advantage
In this method, the unnecessary traffic is reduced and
hence the node able to process the data traffic.
And also send to the destination node in less time.
Drawback
This work didn't develop comprehensive models for
security attacks and a trustworthy security frame-work
against all possible security attacks in an ad hoc network. .

13. IMPROVING THE PERFORMANCE OF PROBABILISTIC
FLOODING IN MANETS (2008)
Methodology
This paper has proposed the probabilistic flooding
algorithm in MANETs.
The algorithm determines rebroadcast probability by
considering network density.
Advantage
The algorithm provides flexibility.
It is easy to implement with guaranteed message
dissemination.
Drawback
If the rebroadcast probability p is set to a small value, the
13 September 14, 2012
reachability will be poor.
14.
PROBABILISTIC BROADCAST FOR FLOODING IN WIRELESS
MOBILE AD HOC NETWORKS (2002)
Methodology
A purely probabilistic approach has been discussed about
flooding, its attempting to exploit the phase transition
phenomenon.
Advantage
To maintain high reliability, when inorder to reduce the
number of broadcast packets.
Drawback
In the mechanism where a system undergoes a small
changes of a given parameter in the system induces a great
shift in the system's global behavior.
The phenomenon should be extremely cost efficient. 14, 2012

15. EFFECTIVE FILTERING SCHEME AGAINST RREQ FLOODING
ATTACK IN MOBILE AD HOC NETWORKS (2007)
Methodology
A simple rate based control packet forwarding mechanism
has been introduced to mitigate malicious control packet.
Advantage
The protocol can be made secure against other types of
possible DOS attacks.
And none of the genuine nodes in the network are wrongly
accused as misbehaving node.
Drawback
This method does not able to distinguish between genuine
and forged RREQs from the malicious or victim nodes.

16. MISTRAL: EFFICIENT FLOODING IN MOBILE AD-HOC
NETWORKS (2006)
Methodology
The Mistral compensating mechanism can support
flooding by a wide range of active applications.
Advantage
The Mistral compensating mechanism can be applied to
other application where the packet loss is an issue.
Drawback
It allows only limited simulation modification.
And the source code can be evaluated with only minor
modifications.

17. MITIGATING FLOODING ATTACKS IN MOBILE ADHOC
NETWORKS SUPPORTING ANONYMOUS
COMMUNICATIONS (2006)
Methodology
Anonymous Secure Routing (ASR) protocol was considered
It analyze how an attacker can severely degrade the
performance of the network.
Advantage
It can effectively identify and eliminate the nodes that are
flooding the network.
Drawback
In ASR routing protocol, it is not possible to track back the
source and destination nodes in an anonymous network.

NOVEL DEFENSE MECHANISM AGAINST DATAFLOODING ATTACKS IN
WIRELESS AD-HOC NETWORKS

IEEE TRANSACTIONS ON CONSUMER ELECTRONICS, VOL. 56, NO. 2, MAY 2010
The identified problem is, When the number of packets per
second is high (burst traffic), AODV cannot process packets
because of the resource exhaustion.
The proposed scheme of Period Based Defense
Mechanism(PDM) enhances the throughput of burst traffic
under the data flooding attack.
PROPOSED WORK
The work is looking forward to use Modified Adhoc
22 Ondemand Distance Vector (MAODV) protocol.
September 14, 2012
23. CONCLUSION
In the first phase, by the discussion of about some
flooding attacks and their prevention measures in
MANETs, its going to implement a Period based defense
mechanism, it is also seen that MAODV would give
better results than AODV.
And in the second phase, the work will aim at
simulating the throughput of the PDM scheme according
to the number of attackers and the number of
transferred packets per second by using NS-2
simulations.
