WIRELESS ADHOC
NETWORK

4. WIRELESS ADHOC NETWORK
• A wireless network is a computer network that uses
wireless data connections for connecting network nodes.
• A wireless ad hoc network (WANET) is a decentralized type
of wireless network.
1. Self-configuring,
2. Dynamic networks
3. Nodes are free to move.

5. WIRELESS ADHOC NETWORK
VPMMECW/CSE/24-02-2016
• Wireless ad-hoc networks can be classified by
their application:
Mobile ad hoc networks (MANETs).
Vehicular ad hoc networks (VANETs).
Smartphone ad hoc networks (SPANs).

6. MANETs
• Mobile Adhoc NETworks.
• Mobile Ad hoc NETwork (MANET) is a collection of mobile
nodes equipped with both a wireless transmitter and a
receiver that communicate with each other either directly or
indirectly.
• Because of MANET’s distributed architecture and changing
topology, a traditional centralized monitoring technique is no
longer feasible in MANETs.
• In such case, it is crucial to develop an intrusion-detection
system (IDS)

7. INTRUSION DETECTION SYSTEM
VPMMECW/CSE/24-02-2016
• An Intrusion Detection System (IDS) is a
Software application that
1. Monitors network for malicious activities
2. Produces electronic reports to a
management station.

8. • Network Intrusion Detection Systems
Network Intrusion Detection Systems (NIDS) are
placed within the network to monitor traffic to
and from all devices .
• Host Intrusion Detection Systems
Host Intrusion Detection Systems (HIDS) run on
individual hosts or devices on the network.

9. OBJECTIVE
VPMMECW/CSE/24-02-2016
• Implementation of IDS for MANETs using
EAACK scheme.
• Comparison of EAACK performance analysis
with other contemporary approaches like ACK
and TWOACK.

10. EXISTING SYSTEM
VPMMECW/CSE/24-02-2016
• Watchdog detects malicious misbehaviour but
fails at receiver collision.
• The TWOACK scheme successfully solves the
receiver collision but has network overhead.
• AACK fail to detect malicious nodes with the
presence of false misbehavior report

11. PROPOSED SYSTEM-ABSTRACT
VPMMECW/CSE/24-02-2016
• Implemented a new intrusion-detection system named
Enhanced Adaptive Acknowledgement(EAACK)
specially designed for MANETs.
• Our proposed approach EAACK is designed to tackle
false misbehavior, limited transmission power, and
receiver collision.
• EAACK demonstrates higher malicious- behaviour -
detection rate but does not greatly affect the
Network Performances.

12. • EAACK is consisted of three major parts, namely, ACK, Secure ACK
(S-ACK), and misbehavior report authentication(MRA).
• ACK is basically an end-to-end acknowledgment scheme, aiming to
reduce network overhead when no network misbehavior is
detected.
• In S-ACK mode, the three consecutive nodes work in a group to
detect misbehaving nodes in the network.
• The core of MRA scheme is to authenticate whether the destination
node has received the reported missing packet through a different
route.

Detection in Mobile Ad Hoc Networks,” in

14. CONFIDANT
• CONFIDANT (Cooperation Of Nodes, Fairness
In Dynamic Ad-hoc NeTworks).
• When a node experiences a misbehaving
node, it will send a warning message to other
nodes called as friends, based on trusted
relationship.
VPMMECW/CSE/24-02-2016

15. OCEAN
VPMMECW/CSE/24-02-2016
• Bansal and Baker also proposed a DSR protocol called
OCEAN (Observation-based Cooperation Enforcement in
Adhoc Networks).
• OCEAN also uses a monitoring system and a reputation
system.
• OCEAN relies only on its own observation to avoid the new
vulnerability of false accusation from second-hand
reputation exchanges.
• OCEAN can be considered as a stand-alone architecture.

16. PROS & CONS
PROS:
 Node Co-operation.
 Effective Data forwarding.
CONS:
 Network Overhead.
 Low Performance.
