Protector Control PC-AODV-BH in The Ad Hoc Networks
In this paper we deal with the protector control that which we used to secure
AODV routing protocol in Ad Hoc networks. The considered system can be
vulnerable to several attacks because of mobility and absence of
infrastructure. While the disturbance is assumed to be of the black hole type,
we purpose a control named "PC-AODV-BH" in order to neutralize the effects of
malicious nodes. Such a protocol is obtained by coupling hash functions,
digital signatures and fidelity concept. An implementation under NS2 simulator
will be given to compare our proposed approach with SAODV protocol, basing on
three performance metrics and taking into account the number of black hole
malicious nodesComment: submit 15 pages, 19 figures, 1 table, Journal Indexing team, AIRCC

DPRAODV: A Dynamic Learning System Against Blackhole Attack In AODV Based MANET
Security is an essential requirement in mobile ad hoc networks to provide protected communication between mobile nodes. Due to unique characteristics of MANETS, it creates a number of consequential challenges to its security design. To overcome the challenges, there is a need to build a multifence security solution that achieves both broad protection and desirable network performance. MANETs are vulnerable to various attacks, blackhole, is one of the possible attacks. Black hole is a type of routing attack where a malicious node advertise itself as having the shortest path to all nodes in the environment by sending fake route reply. By doing this, the malicious node can deprive the traffic from the source node. It can be used as a denial-of-service attack where it can drop the packets later. In this paper, we proposed a DPRAODV (Detection, Prevention and Reactive AODV) to prevent security threats of blackhole by notifying other nodes in the network of the incident. The simulation results in ns2 (ver-2.33) demonstrate that our protocol not only prevents blackhole attack but consequently improves the overall performance of (normal) AODV in presence of black hole attack
AODVSEC: A Novel Approach to Secure Ad Hoc on-Demand Distance Vector (AODV) Routing Protocol from Insider Attacks in MANETs
Mobile Ad hoc Network (MANET) is a collection of mobile nodes that can
communicate with each other using multihop wireless links without requiring any
fixed based-station infrastructure and centralized management. Each node in the
network acts as both a host and a router. In such scenario, designing of an
efficient, reliable and secure routing protocol has been a major challenging
issue over the last many years. Numerous schemes have been proposed for secure
routing protocols and most of the research work has so far focused on providing
security for routing using cryptography. In this paper, we propose a novel
approach to secure Ad hoc On-demand Distance Vector (AODV) routing protocol
from the insider attacks launched through active forging of its Route Reply
(RREP) control message. AODV routing protocol does not have any security
provision that makes it less reliable in publicly open ad hoc network. To deal
with the concerned security attacks, we have proposed AODV Security Extension
(AODVSEC) which enhances the scope of AODV for the security provision. We have
compared AODVSEC with AODV and Secure AODV (SAODV) in normal situation as well
as in presence of the three concerned attacks viz. Resource Consumption (RC)
attack, Route Disturb (RD) attack, Route Invasion (RI) attack and Blackhole
(BH) attack. To evaluate the performances, we have considered Packet Delivery
Fraction (PDF), Average End-to-End Delay (AED), Average Throughput (AT),
Normalized Routing Load (NRL) and Average Jitter and Accumulated Average
Processing Time.Comment: 20 Pages, 24 Figure
A Review of the Energy Efficient and Secure Multicast Routing Protocols for Mobile Ad hoc Networks
This paper presents a thorough survey of recent work addressing energy
efficient multicast routing protocols and secure multicast routing protocols in
Mobile Ad hoc Networks (MANETs). There are so many issues and solutions which
witness the need of energy management and security in ad hoc wireless networks.
The objective of a multicast routing protocol for MANETs is to support the
propagation of data from a sender to all the receivers of a multicast group
while trying to use the available bandwidth efficiently in the presence of
frequent topology changes. Multicasting can improve the efficiency of the
wireless link when sending multiple copies of messages by exploiting the
inherent broadcast property of wireless transmission. Secure multicast routing
plays a significant role in MANETs. However, offering energy efficient and
secure multicast routing is a difficult and challenging task. In recent years,
various multicast routing protocols have been proposed for MANETs. These
protocols have distinguishing features and use different mechanismsComment: 15 page
