Nowadays Mobile Ad Hoc Network MANET is an emerging area of research to provide various communication services to the end users. Recently the fields of MANET have yielded more and more popularity and thus MANET have become a subject of great interest for the researchers to enforce research activities. One of the main challenges in Mobile ad hoc network is of searching and maintaining an effective route for transporting data information securely. Security and privacy are indispensable in various communications for successful acceptance and deployment of such a technology. Mobile Ad Hoc Network MANET is the cooperative engagement of a collection of mobile nodes without the required intervention of any centralized access point or existing infrastructure. There is an increasing trend to adopt mobile ad hoc networking for commercial uses however, their main applications lie in military, tactical and other security sensitive operations. In these and other applications of mobile ad hoc networking, secure routing is an important issue. Thinking of this, I proposed an efficient secure ad hoc routing protocol for optimize the performance of MANET which will more efficient in terms of time delay, packet drop and packet delivery fraction in mobile ad hoc network. The proposed protocol can employ an integrated approach of digital signature and encryption techniques to achieve the security goals like message integrity, data confidentiality and end to end authentication at IP layer.

Performance Analysis of Communication Protocols for Post Disaster CommunicationAM Publications,India
Natural and catastrophic disasters can cause damage to the communication system, the damage may be complete or it may be partial. In such areas communication and exchange of information plays a very important role and become difficult to happen in such situations. So, the rescue systems should be installed in those areas for the rescue operations and to take important decisions about how to make a connection from there to the outside world. Wireless communication network architecture should be setup in disaster areas for the communication to happen and to gather information. In this document, wireless ad-hoc access node network architecture has been proposed. These access nodes acts as hotspot for certain area in which they are set up such that the Wi-Fi capable devices get connected to them for communication to happen. If the mobile battery is drained in such situations wireless charging using microwave is shown in this paper. Performance analysis of the communication transport layer protocols is shown and new-SCTP algorithm is developed which shows the better results in terms of cumulative packet loss.

Wideband Sensing for Cognitive Radio Systems in Heterogeneous Next Generation...CSCJournals
Mobile Next Generation Network (MNGN) is characterized as heterogeneous network where variety of access technologies are meant to coexist. Decisions on choosing an air interface that meets a particular need at a particular time will be shifted from the network’s side to (a more intelligent) user’s side. On top of that network operators and regularities have come to the realization that assigned spectrum bands are not utilized as they should be. Cognitive radio stands out as a candidate technology to address many emerging issues in MNGN such as capacity, quality of service and spectral efficiency. As a transmission strategy, cognitive radio systems depend greatly on sensing the radio environment. In this paper, we present a novel approach for interference characterization in cognitive radio networks based on wideband chirp signal. The results presented show that improved sensing accuracy is maintained at tolerable system complexity.

Beamforming for millimetre-wave (mmWave) frequencies has been studied for many years. It is considered as an important enabling technology for communications in these high-frequency ranges and it received a lot of attention in the research community. The special characteristics of the mmWave band made the beamforming problem a challenging one because it depends on many environmental and operational factors. These challenges made any model-based architecture fit only special applications, working scenarios, and specific environment geometry. All these reasons increased the need for more general machine learning based beamforming systems that can work in different environments and conditions. This increased the need for an extended adjustable dataset that can serve as a tool for any machine learning technique to build an efficient beamforming architecture. Deep MIMO dataset has been used in many architectures and designs and has proved its benefits and flexibility to fit in many cases. In this paper, we study the extension of collaborative beamforming that includes many cooperating base stations by studying the impact of User Equipment (UE) speed ranges on the beamforming performance, optimizing the parameters of the neural network architecture of the beamforming design, and suggesting the optimal design that gives the best performance for as a small dataset as possible. Suggested architecture can achieve the same performance achieved before with up to 33% reduction in the dataset size used to train the system which provides a huge reduction in the data collection and processing time.

MOBILE IP ON MOBILE AD HOC NETWORKS: AN IMPLEMENTATION AND PERFORMANCE EVALUA...acijjournal
Mobile computing devices equipped with transceivers form Mobile Ad Hoc Networks (MANET), when two
or more of these devices find themselves within transmission range. MANETs are stand-alone (no existing
infrastructure needed), autonomous networks that utilise multi-hop communication to reach nodes out of
transmitter range. Unlike infrastructure networks e.g. the Internet with fixed topology, MANETs are
dynamic. Despite the heterogeneous nature of these two networks, integrating MANETs with the Internet
extends the network coverage area of the Internet, and adds to the application domain of MANETs. One of
the many ways of combining MANETs with the Internet, is the use of Mobile Internet Protocol (Mobile IP)
alongside a MANET routing protocol, to route packets between the Internet and the MANET, via Gateway
agents. In this paper, we evaluate the performance of Mobile IP on MANET in Network Simulator 2 (NS2).
We have implemented Mobile IP on Ad hoc On-demand Distance Vector (AODV), Ad hoc On-demand
Multiple Distance Vector (AOMDV) and Destination-Sequenced Distance Vector (DSDV) routing
protocols, and compared performances based on Throughput, End-to-End Delay (E2ED), Packet Delivery
Ratio (PDR) and Normalized Packet Ratio (NPR). The simulation results suggest that, on-demand routing
within the MANET better serves Mobile IP on MANETs.
A Protocol/Scheme to mitigate DDos attacks using AODV Protocolijsrd.com
MANET(Mobile Adhoc Network) is an emerging technology and have great strength to be applied in battlefields and commercial applications such as traffic surveillance, MANET is infrastructure less without any centralized controller. Each node contains routing capability. Each device in a MANET is independent and can move in any direction. One of the major challenges wireless mobile ad-hoc networks face today is security, because no central controller exists. MANETs are a kind of wireless ad hoc networks that usually has a routable networking environment on top of a link layer ad hoc network. There are many security attacks in MANET and DDoS (Distributed denial of service) is one of them. Our main objective is seeing the effect of DDoS in routing, Packet Drop Rate, End to End Delay, no. of Collisions due to attack on network. And with these parameters and many more also we build secure IDS to detect this kind of attack and block it. In this thesis main objective is to study and implement the security against the DDOS attack. DDoS (Distributed Denial of Service) attacks in the networks are required to be prevented, as early as possible before reaching the victim node. DDos attack causes depletion of the network resources such as network bandwidth, disk space, CPU time, data structures, and network connections. Dealing with DDoS attacks is difficult due to their properties such as dynamic attack rates, big scale of botnets. DDos attack become more difficult to handle if it occurs in wireless network because of the properties of ad hoc network such as dynamic topologies, low battery life, Unicast routing Multicast routing , Frequency of updates or network overhead , scalability , mobile agent based routing ,power aware routing etc. Thus it is better to prevent the distributed denial of service attack rather than allowing it to occur and then taking the necessary steps to handle it. The following quantitative metrics Packet Delivery Ratio (PDR), Number of Collisions are to be used to evaluate the performance of DDoS attacks and their prevention techniques under different combinations in the fixed mobile ad hoc network. In our simulation, the effect of DDoS attacks under different number of attackers is studied.
In this thesis firstly we study the effects of Black hole attack in MANET using both Proactive and Reactive routing protocols and then discovering a Secure Path in MANET by Avoiding Black/Gray Holes. The impact of Black Hole attack on the performance of MANET is evaluated finding out which protocol is more vulnerable to the attack and how much is the impact of the attack on both protocols. blackhole route
Secured Intrusion Protection System through EAACK in MANETSijtsrd
Achieving reliable routing has always been a major issue in the design of communication networks, due to the absence of fixed infrastructure among which mobile ad hoc networks MANETs that can take control of the most adversarial networking environment, and the dynamic network topology the nature of open transmission media. In the MANETs these characteristics also more challenging to make the design of routing protocols. The network topology varies so to determining feasible routing paths for distributing messages in a decentralized is a difficult job. Factors such as the extensive distribution of nodes and open medium, variable wireless link quality topological changes, and propagation path loss become pertinent issues and make MANET unprotected to instructions. Thus, it becomes central to develop a systematic intrusion detection scheme to secure Mobile Ad Hoc networks from intruders. In this project, we put forward and applied an efficient IDS mechanism based on Enhanced Adaptive Acknowledgment EAACK especially made for MANETs which performs better than the earlier techniques such as AACK, TWOACK and Watchdog.

An intrusion detection mechanism for manets based on deep learning artificial...IJCNCJournal
Mobile Ad-hoc Network (MANET) is a distributed, decentralized network of wireless portable nodes connecting directly without any fixed communication base station or centralized administration. Nodes in MANET move continuously in random directions and follow an arbitrary manner, which presents numerous challenges to these networks and make them more susceptible to different security threats. Due to this decentralized nature of their overall architecture, combined with the limitation of hardware resources, those infrastructure-less networks are more susceptible to different security attacks such as black hole attack, network partition, node selfishness, and Denial of Service (DoS) attacks. This work aims to present, investigate, and design an intrusion detection predictive technique for Mobile Ad hoc networks using deep learning artificial neural networks (ANNs). A simulation-based evaluation and a deep ANNs modelling for detecting and isolating a Denial of Service (DoS) attack are presented to improve the overall security level of Mobile ad hoc networks.

MOVEMENT ASSISTED COMPONENT BASED SCALABLE FRAMEWORK FOR DISTRIBUTED WIRELESS...ijcsa
Intelligent networks are becoming more enveloping and dwelling a new generation of applications are
deployed over the peer-to-peer networks. Intelligent networks are very attractive because of their role in
improving the scalability and enhancing performance by enabling direct and real-time communication
among the participating network stations. A suitable solution for resource management in distributed wireless systems is required which should support fault-tolerant operations, requested resources (at shortest path), minimize overhead generation during network management, balancing the load distribution between the participating stations and high probability of lookup success and many more. This article
presents a Movement Assisted Component Based Scalable Framework (MAC-SF) for the distributed
network which manages the distributed wireless resources and applications; monitors the behavior of the
distributed wireless applications transparently and attains accurate resource projections, manages the
connections between the participating network stations and distributes the active objects in response to the

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

cellular phone to check e-mail, browse internet, GPRS, GPS; travelers with moveable devices
can surf the internet from airports, railway stations, coffee shop and other public locations;
researchers can switch over files and other information by connecting portable computers via
wireless LANs; at home, users can coordinate data and transfer files between portable devices
and desktops.
From last some years not only mobile devices are getting smaller, cheaper, more
convenient, and more configured, they also run more applications and network services
which increasing the growth of mobile computing equipment market. The blowing up
number of Internet and laptop users pouring this growth further [8]. Projections show that in
the next couple of years the number of mobile connections and the number of shipments of
mobile and Internet terminals will grow yet by another 20–50% [8].
The paper aims to advance the perceptive of MANET networks and its use. Our main
research contribution provides an automated assessment process to analyze security
properties. These contributions harmonize the current non-exhaustive and non-automated
MANET security analysis approaches to provide a more wide-ranging security analysis
potential to evaluate security properties in MANET Network. More recently, new alternative
ways to deliver the services have been rising. These are paying attention around having the
mobile devices connect to each other in the transmission range through automatic
configuration, setting up an ad hoc mobile network that is both flexible and influential. In this
way, not only can mobile nodes communicate with each other, but can also receive internet
services through Internet Gateway node, effectively and securely enhancing internet services
to the non-infrastructure area. Primary characteristics, such as dynamically altering topology,
non-infrastructure support, resource-constrained capacity and wireless transmission, make
MANETs quite different from conventional wired or wireless networks. Most accessible
security methods those are valid in traditional networks but not suitable for a MANET
environment. In this, we study the security at data link layer, securing routing and onforce
collaboration.
This paper presents the impulsion behind mobile ad hoc networks, and presents a
delegate collection of technology solutions used at the different layers of the network.
The paper is prepared as follows. In Introduction of Mobile Ad Hoc Network, we look at
mobile ad hoc networks in closer detail with development, covering their specific
characteristics, advantages, as well as design challenges. This is followed by a security of
MANET which covers the Cross-layer research areas, including, energy management,
security and cooperation, Quality of Service, and performance evaluation. Finally, we
conclude the whole paper.
2. MOBILE AD HOC NETWORKS
Mobile and ubiquitous computing has been probable now due to the advances in modern
wireless communication technology, aiming to provide “anywhere, anytime” communication
services for users. Wireless ad hoc networking is such an sophisticated wireless transmission
technology, which can be rapidly deployed in any area to provide mobile communication
services without any fixed spinal column infrastructure support. By allowing multi-hop
transmission, out of range communication can be achieved in wireless ad hoc networks,
which reduces the requirement of the infrastructure-based backbone. In other words, a
wireless ad hoc network can be easily created at anywhere when needed, particularly in
places where infrastructure-based communication system cannot be shaped due to
geographical or terrestrial constraints.

2.1. MANET advancement
In history, mobile ad hoc networks have principally been used for creating new art of network
organization where either the infrastructure is gone or where position an infrastructure is not
very cost effective [2]. Pure wireless communication also has restriction in that radio signals
are subject to intrusion and radio frequency higher than 100 MHz not often promulgate
beyond line of sight (LOS) [9]. Mobile ad hoc network creates a appropriate structure to
address these issues by providing a multi-hop wireless network without pre-placed
infrastructure and connectivity ahead of LOS. The whole life-cycle of ad-hoc networks could
be divided into the First, Second, and the Third generation ad-hoc networks systems. Present
ad-hoc networks systems are considered the Third generation.
The first generation goes back to 1972. At the time, they were addressed PRNET
(Packet Radio Networks) developed by DARPA. The PRNET used a mixture of ALOHA and
CSMA approaches for medium access, and a type of distance-vector routing.
The second generation of ad-hoc networks emerged in 1980s, when the ad-hoc
network systems were additional improved and implemented as a part of the SURAN
(Survivable Adaptive Radio Networks) program which was developed by DARPA. This
provided a packet-switched network to the mobile battleground in an environment without
infrastructure. SURAN was developed to conquer the problem of PRNET like network
scalability, security, processing capabilities and energy management. The main objectives
were to develop network algorithms to support a network that can scale to tens of thousands
of nodes and endure security attacks, as well as use small, low-cost, low-power radios that
could support sophisticated packet radio protocols [9]. This effort consequences in the design
of Low-cost Packet Radio (LPR) technology in 1987 [10],
In the 1990s, the idea of commercial ad-hoc networks arrived with notebook
computers and other practical communications equipment. At the same time, the idea of a set
of mobile nodes was projected at several research conferences.
The IEEE 802.11 subcommittee had adopted the term "ad-hoc networks" and the research
community had in progress to work on the likelihood of deploying ad-hoc networks in
different areas of function. In the early 1990s a epidemic of new developments signaled a
new stage in ad hoc networking. Notebook computers became well-liked for feasible
communications equipment based on RF (Redio Frequency) and infrared. The idea of an
infrstructureless collection of mobile hosts was planned in two conference papers [11, 12]
and the IEEE 802.11 subcommittee adopted the term “ad hoc networks.” The idea of
commercial (non-military) ad hoc networking had inwards.
At around the same time, the DOD in progress where it left off, financial support
programs such as the Global Mobile Information Systems (GloMo), and the Near-term
Digital Radio (NTDR) The aim of GloMo were to give connectionless Ethernet kind
environment in office as anytime, anywhere, in portable devices such as mobile, tablet,
computer and GPS. Channel access approaches were now in the CSMA/CA and TDMA
molds, and a number of narrative routing and topology control schemes were developed. The
NTDR used clustering and link- state routing, and self-organized into a two-tier ad hoc
network [3]. The US Army is used NTDR today only, it is the merely “real” non-prototypical
ad hoc network. The rising interest in ad hoc networking has optimistic a number of standards
and commercials behavior to evolve in the mid to late ’90s. The Mobile Ad Hoc Networking
(MANET), in IETF, operational group developed, and sought to regulate routing protocols

ISSN 2248- 9363 (Print), ISSN- 2248-9371 (Online) Volume 3, Number 1, Jan-March (2013)
for ad hoc networks. The growth of routing within the MANET working group and the bigger
community branched into reactive (routes on- demand) and proactive (routes ready-to-use)
routing protocols [4]. The 802.11 subcommittee standardized a medium access protocol that
was based on collision avoidance and tolerated hidden terminals, making it usable, if not
most favorable, for building mobile ad hoc network prototypes out of notebooks and 802.11
PCMCIA cards. HIPERLAN and Bluetooth were some other standards that addressed and
benefited ad hoc networking [3].
2.2 Ad hoc networking issues
There are some specific MANET issues and constraints which create evils and
significant challenges in ad hoc network plan. To present the enormous amount of research
activities on ad hoc networks in a methodical way, we will use, as a suggestion, the simplified
architecture shown in following Fig. [1].
Fig [1]: Simple architecture for Ad Hoc Network
As shown in the figure, the research activities will be conbined, according to a layered
approach into three main areas:
• Enabling technologies; • Networking; • Middleware and applications.
In addition, as shown in the figure, a number of issues (energy management, security and
cooperation, quality of service, network simulation) extent all areas, and we discuss them
independently [1].
3. NETWORK SECURITY AND COOPERATION
In MANETs, all the nodes are infrastructureless so by nature they are wireless mobile ad hoc,
so we neeed to look new security challenge to the network plan. We also need to sacrifies the
information and security in wireless ad hoc network than permanent wired networks.
Susceptibility of channels and nodes, lack of infrastructure and vigorously altering topology,
make ad hoc networks security a difficult job [13]. Nodes do not exist in in physically
protected places, and so they can be easily attacked by the attacker and forbidden by them.
The absence of infrastructure makes the traditional security solutions such as certification

establishment (Maintain by the some central Authority) and on-line servers unsuitable (which
maintian the nodes information). Lastly, the security of routing protocols in the MANET
dynamic environment is an supplementary challenge.
The self-organizing environment introduces new security issues that are not included in basic
security services provided in wired networks. So the security accessible in MANET is not
good adequate for rightness and integrity of information which are shared. A basic necessity
for keeping the network prepared is to enforce ad hoc Nodes involvement to network
operations, in spite of the conflicting propensity (motivated by the energy motivated) of each
node towards selfishness [14,15].
3.1. Security attacks
Securing wireless ad hoc networks is a large challenge. Before preparatory to provide
security in MANET or any ad hoc network, it is essential to understand probable form of
attacks. Ad hoc networks have to cope with the similar kinds of vulnerabilities as their wired
counterparts, as well as with new vulnerabilities specific to the ad hoc context [16]. In
addition, traditional vulnerabilities are also noticed by the ad hoc prototype.
The difficulty and variety of the field (different applications have different security
constraints) led to a huge number of proposals that can not be all surveyed in this editorial.
Comprehensive analyses of ad hoc networking security issues and solutions can be found in
[13, 17, and 18]. Underneath we summarize how to classify the attacks. The following Figure
shows a classification of possible security attacks in MANETs.
Fig [2]: categorization of Attacks
Performing communication in free space exposes ad hoc networks to attacks as anyone can
join the network, and eavesdrop or insert messages. Ad hoc networks attacks can be classified
as inactive or active [19].
Active attack can be defined as “the attacker or impostor modify or alter the data
which can be shared among the nodes in the networks”. In a MANET, an attacker humiliate
the network performance by inappropriately modifying the routing message, injecting
mistaken messages, or pretending an authorized Mobile Node to confuse the normal network
5
6. International Journal of Computer science and Engineering Research and Development (IJCSERD),
ISSN 2248- 9363 (Print), ISSN- 2248-9371 (Online) Volume 3, Number 1, Jan-March (2013)
procedure. Active attacks can be further categorized as routing disruption attacks and
resource consumption attacks depending on the purpose of the attackers. In routing
disturbance attacks, the attacker send legal bits or packets in a malicious way; while in
resource utilization attacks, the attacker aims to gain precious network resources, such as
radio bandwidth, users’ energy, memory space and computational power. Depending on the
events taken by an attacker, active attacks can be classified into several common attack
subcategories as follows.
Packet dropping: An intruder pretends to be Mobile Node or genuine user itself from
others Mobile Nodes. In this attacker will throw away or destroy all the packets which
are routed to him. This is identified as black hole attack. In black hole attack, attacker
sends fake routing packets, so that it can route all the packets for some destinations to
itself, and then remove them. As a special case, an attacker can decide selective
packets and drop them as a substitute of discarding all packets, thus creates a grayhole
attack.
Modification: A spiteful node modifies message throughout the transmission
between the communicating nodes, For example, an attacker can deliberately
shorten or lengthen the node list in the routing packet, curtail or lengthen the
messages.
IP spoofing: A spiteful node sends a internet protocol packet containing its own
MAC address and a victim’s IP address, thereby usurping the IP-to-MAC address
binding of the victim from the other neighbor’s Address Resolution Protocol
(ARP) cache.
Tunneling attack: A spiteful node creates a different type of routing disturbance,
called as tunneling attack [20], and by using a pair of spiteful nodes connected
together via a private network connection. Every packet node a received can be
forwarded to node b through their private connection. This attack can potentially
disturb routing by shortcircuiting the usual flow of routing packets. It means that if
authorized sender sends packets, it will be catched by private network of intruder
being receiver and then intruder send smashed packets to authorized receiver.
DoS: An attacker can mount a replay attack by sending old messages to a destination
node again and again, aiming to excess the network and wear out the node’s
resources. Moreover, an attack can generate a speeding up attack in this he sends
routing request packets with high frequency to find real route and keep other nodes
busy. The reason here is to make the network service not available for other lawful or
authorized nodes. The Routing Table Overflow and the Sleep Depravation attacks
[236, main peper] fall in this class.
Passive attack: is an attack where an unofficial attacker monitors or listens to the
communication among two parties. It means that attacker or intruder never send any
corrupted message in a MANET network. An attacker may inactively listen to the
network traffic to collect valuable information, such as network connectivity, node
location, traffic distribution, and so on. The main goal of passive attacks is to generate
threat against the network privacy. Compared with active attacks, passive attacks are
very tough to prevent and detect because the intruders are not concerned in any
change of transmitted message or disruption of the network activity. Depending on
6
7. International Journal of Computer science and Engineering Research and Development (IJCSERD),
ISSN 2248- 9363 (Print), ISSN- 2248-9371 (Online) Volume 3, Number 1, Jan-March (2013)
dissimilar actions taken by an attacker, passive attacks can be further separated into
following subcategories.
Eavesdropping: An attacker can get direct knowledge of the network by intercepting
transmitted data packets. Passive eavesdropping can be prohibited by a variety of
encryption schemes and defensive the privacy of the data transmission, so attacker
can not recognize the encrypted data and its’ key.
Traffic analysis attacks: An attack may dig out valuable information from the
distinctiveness of the transmission such as node identity, the amount of transmitted
packets, time required to send one bit or a packet and the frequency of data
transmission. The extracted information may allow the attacker to do a auxiliary
analysis and figure out some sensitive knowledge [21, 22].
3.2. Basic security mechanisms:
Essentially there are two types of security in wired and wrireless: preventive and
detective. The defensive mechanisms mean we can try to stop unconstitutional access in our
shared network. Defensive mechanisms are classically based on key-based cryptography.
Keys delivery is main point for these mechanisms. Secret keys are dispersed through two
methods one is symmentric and other is asymmetric. We need to set up secure channel for
sharing key in symmetric cryptography but it is difficult to apply in ad hoc networks. In
asymmentric, we use public key distribution. An asymmetric cryptography means, there two
keys one is public key and other is private key. A public key can be shared among all the
parties who are in network and private key is only secure with particular user. Public keys are
dispersed through certificates that bind a public key for network users. In the centralized
approach, certificates are provided, stored, and distributed by the Certificate Authority (CA).
Because no central authority no centralized trusted and third party and server are probable in
MANET, the key management purpose needs to be distributed over Nodes. The server takes
the accountability for key management shared among a set of Nodes [24]. The challenge of
creating such a confidence mixture does not depend on only costructing and configuring the
aggregation, but it is also depends on hoe we provide security to such aggregation when the
network topology is changed with moving or mobile users, Although we can create a
completely distributed self organizing public key management system for MANETs [23]. In
this approach the users issue certificates for every other based on their personal links.
Certificates are stored in a local certificate database and dispersed by the users themselves.
When two users want to verify the public keys of each other, they combine their local
certificate databases. The authors analyze the vulnerabilities of key-based security
mechanisms, and suggest solutions to defend these mechanisms [16].
The discovery mechanism means we just find out that where the illegal activities are
happened. Most of the imposition detection techniques developed on a fixed wired network
are not applicable on MANETs. In ad hoc network there are no traffic consciousness points
like switches, routers, etc. where the intrusion detection system (IDS) can gather inspected
data for the whole network. In mobile ad hoc network IDS require to depend on only
accessible audit information which was composed within the radio variety So the intrusion
detection algorithm must rely on this incomplete and localized information. A proposal for a
new intrusion detection structural design that is both distributed and cooperative is presented
in [25, 26]. To find out the intrusion detection in MANET, all the authorized users contribute
in intrusion detection and response. Each node is in charge for detecting symbols of attacks

ISSN 2248- 9363 (Print), ISSN- 2248-9371 (Online) Volume 3, Number 1, Jan-March (2013)
locally and separately, but when neighbors want to detect intrusion, they need to create
collaboratively study in a broader range.
3.3. Security at data link layer
Bluetooth and 802.11 apply mechanisms based on cryptography to stop unauthorized
accesses, and to advance the privacy on radio links. An investigation of the various 802.11
and Bluetooth mechanisms can be found in [18].
Security in the IEEE 802.11 standard is provided by the Wired Equivalent Privacy
(WEP) scheme which provide the security same as wired security. WEP provides both data
encryption and integrity. So when data is sent and received by two parties, are in real form.
The security is based on a 40-bit secret key. The secret key can also be a default key shared
by all the devices of a WLAN in asymmetric encryption, or a pairwise secret key shared only
by two communicating devices in symmetric encryption. Since WEP does not provide any
support for the exchange of secret keys, the secret key must be manually shared by authorized
communicating parties. As WEP suffers from various design flaws and weaknesses [18], So
IEEE 802.11 standardization is designing the new 802.11 security architecture for correcting
problems.
Bluetooth uses cryptographic security mechanisms implemented in the data link layer.
A key management service provides each device with a set of symmetric cryptographic keys
necessary for the initialization of a secret channel with another device, the implementation of
an authentication protocol, and the switch over of encrypted data on the secret channel. A
thorough presentation of Bluetooth security mechanisms, together with an analysis of the
weaknesses in the Bluetooth key management scheme can be found. [18]
3.4. Secure routing
The spiteful nodes change the information about the routing protocol for disrupting
the accurate performance information. They also try to imagine other nodes to share the
packets. Modern studies [27] brought up also a new type of attack that goes under the name
of wormhole attack mentioned earlier.
We next sum up the recent research that has been done in order to come up with
secure routing protocols for ad hoc networks. [28, 18] The Secure Routing Protocol [29] is
conceived as an addition of simple routing protocol. It menas the security application can be
applied to numerous existing routing protocols. SRP is based on the supposition of the being
of a security association between the sender and the receiver based on a shared secret key
negotiated at the connection setup. SRP fights with attacks that disrupt the route discovery
process. A node initiating a route discovery is capable to identify and discard false routing
information. Likewise to SRP, Ariadne [30] assumes that each pair of communicating nodes
has two secret keys (one for each direction of the communication). So that when we use
Ariadne protocol, that time both users uses secret key to send information to receivers.
Ariadne is a secure ad hoc routing protocol based on DSR (Dynamic Source Routing) and the
TESLA (Timed Efficient Stream Loss-tolerant Authentication protocol) [31].
The Authenticated Routing for Ad hoc Network (ARAN) protocol is storng protocol
to provide defensive and detective security for MANETs. It is secure, routing protocol that
detects and protects alongside malicious actions carried out by third parties in the ad hoc
surroundings [32]. ARAN is based on certificates mechanism which is provided by the

ISSN 2248- 9363 (Print), ISSN- 2248-9371 (Online) Volume 3, Number 1, Jan-March (2013)
trusted certificate server and later on allowed to join ad hoc network. ARAN utilizes a route
discovery process similar to AODV (Ad Hoc on demand Distance Vector Routing). The route
discovery develops en to end authentication among two authorirized nodes and assure that
merely destination node can respond to a route discovery packet.
The Secure Efficient Ad hoc Distance (SEAD) is a practical secure routing protocol based on
DSDV (Deastination Sequensed Distance Vector). SEAD deals with attackers that modify a
routing table update message. The basic idea is to authenticate the sequence number and the
metric field of a routing table keep informed message using oneway hash functions [33].
Hash chains and digital signatures are used by the SAODV mechanism to secure AODV [34].
4. CONCLUSION
The development of MANET cannot be divided from the the world of computing. Since it is
portable and compact media with which we can communicate exclusive of wired network. In
this review paper we discussed some typical and dangerous vulnerability in the MANET,
attack types security criteria, which move on to supply guidance to the security-related
research works in this area. Due to the absence of a clear line of protection or communication
in MANETs, a complete security solution for them should integrate both proactive and
reactive approaches. The solution should cover of all three mechanisms: prevention, detection
and reaction. It means when we want to provide secure communication channel in MANET
that time it must secure sufficient to prevent unauthorized penetration, sense where the
intrusion is occurred and give proper action to that intrusion or attack. The MANETs security
issues endorse new ideas. It has got impending widespread applications in military, corporate
and civilian communications. In these networks all the nodes are helpfully dependant to
perform networking function. This paper mentions many secure protocol which can be used
to provide cryptogrsphy and time based security. One such misconduct is related to routing of
packets. When such unruly nodes take part in the route discovery process, but refuse to
forward the data packets, routing performance may be tainted cruelly.
