EAACK—A
Secure Intrusion-Detection System for MANETs
ABSTRACT:
The migration
to wireless network from wired network has been a global trend in the past few
decades. The mobility and scalability brought by wireless network made it
possible in many applications. Among all the contemporary wireless networks, Mobile
Ad hoc NETwork (MANET) is one of the most important and unique applications. On
the contrary to traditional network architecture, MANET does not require a
fixed network infrastructure; every single node works as both a transmitter and
a receiver. Nodes communicate directly with each other when they are both
within the same communication range. Otherwise, they rely on their neighbors to
relay messages. The self-configuring ability of nodes inMANETmade it popular
among critical mission applications like military use or emergency recovery.
However, the open medium and wide distribution of nodes make MANET vulnerable
to malicious attackers. In this case, it is crucial to develop efficient intrusion-detection
mechanisms to protect MANET from attacks. With the improvements of the
technology and cut in hardware costs, we are witnessing a current trend of expanding
MANETs into industrial applications. To adjust to such trend, we strongly
believe that it is vital to address its potential security issues. In this
paper, we propose and implement a new intrusion-detection system named Enhanced
Adaptive ACKnowledgment (EAACK) specially designed for MANETs. Compared to
contemporary approaches, EAACK demonstrates higher malicious-behavior-detection
rates in certain circumstances while does not greatly affect the network
performances.
EXISTING SYSTEM:
By definition,
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 via
bidirectional wireless links either directly or indirectly. Unfortunately, the
open medium and remote distribution of MANET make it vulnerable to various
types of attacks. For example, due to the nodes’ lack of physical protection, malicious
attackers can easily capture and compromise nodes to achieve attacks. In
particular, considering the fact that most routing protocols in MANETs assume
that every node in the network behaves cooperatively with other nodes and presumably
not malicious, attackers can easily compromise MANETs by inserting malicious or
noncooperative nodes into the network. Furthermore, 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) specially designed for MANETs.
DISADVANTAGES OF EXISTING SYSTEM:
Watchdog scheme
fails to detect malicious misbehaviors with the presence of the following: 1)
ambiguous collisions; 2) receiver collisions; 3) limited transmission power; 4)
false misbehavior report; 5) collusion; and 6) partial dropping.
The TWOACK
scheme successfully solves the receiver collision and limited transmission
power problems posed by Watchdog. However, the acknowledgment process required
in every packet transmission process added a significant amount of unwanted
network overhead. Due to the limited battery power nature of MANETs, such
redundant transmission process can easily degrade the life span of the entire
network.
The concept of
adopting a hybrid scheme in AACK greatly reduces the network overhead, but both
TWOACK and AACK still suffer from the problem that they fail to detect
malicious nodes with the presence of false misbehavior report and forged
acknowledgment packets.
PROPOSED SYSTEM:
In fact, many
of the existing IDSs in MANETs adopt an acknowledgment-based scheme, including
TWOACK and AACK. The functions of such detection schemes all largely depend on
the acknowledgment packets. Hence, it is crucial to guarantee that the
acknowledgment packets are valid and authentic. To address this concern, we
adopt a digital signature in our proposed scheme named Enhanced AACK (EAACK).
ADVANTAGES OF PROPOSED SYSTEM:
Our proposed approach EAACK is designed
to tackle three of the six weaknesses of Watchdog scheme, namely, false misbehavior,
limited transmission power, and receiver collision.
