Abstract
Ad hoc networks are built on the basis of a communication without infrastructure and major investigations have focused on the routing and autoconfiguration problems. However, there is a little progress in solving the secure autoconfiguration problems in mobile ad hoc networks (MANETs), which has led to the proliferation of threats given the vulnerabilities of MANETs. It is clear that ad hoc networks have no centralized mechanism for defense against threats, such as a firewall, an intrusion detection system, or a proxy. Therefore, it is necessary that the defense of interests of each of the ad hoc components is the responsibility of each member node. This paper shows the most common threats to ad hoc networks and reviews several proposals that attempt to minimize some of these threats, showing their protection ability and vulnerabilities in light of the threats that might arise.

AN ANALYSIS OF SECURITY CHALLENGES IN MOBILE AD HOC NETWORKS
Mobile Ad Hoc Network (MANET) is a collection of wireless mobile nodes with restricted transmission range and resources, no fixed infrastructure and quick and easy setup. Because of special characteristics, wide-spread deployment of MANET faced lots of challenges like security, routing and clustering. The security challenges arise due to MANETs selfconfiguration and self-maintenance capabilities. In this paper, we present an elaborate view of issues in MANET security. We discussed both security services and attacks in detail. Three important parameters in MANET security are defined. Each attack has been analyses briefly based on its own characteristics and behaviour. In addition, defeating approaches against attacks have been evaluated in some important metrics. After analyses and evaluations, future scopes of work have been presented.

An Overview of security issues in Mobile Ad hoc Networks
Mobile ad hoc networks (MANETs) are collections of self-organizing mobile nodes with dynamic topologies and no centralized authority. Each node participating in the network acts both as host and a router. So each node can participate to transfer data packet to destination node but suppose one node in network is removed at time it is very difficult to maintain the information about all node. The main advantage and disadvantage of MANETs provides large number of degree of freedom and self-organizing capability of that make it completely different from other network. Due to the nature of MANETs, to design and development of secure routing is challenging task for researcher in an open and distributed communication environments. In MANET, the more security is required in comparison to wired network. If source node chooses this fake route, malicious nodes have the option of delivering the packets or dropping them.

Security in ad hoc networks
Ad hoc networks are a wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, these networks are self-configurable and autonomous systems which are able to support movability and organize themselves arbitrarily. These unique characteristics of ad hoc networks pose a number of challenges for the implementation of security infrastructure in the wireless network system design. In this paper, we study the ad-hoc architecture thus understanding the vulnerabilities and security goals. Further, we discuss the various security attacks and explore approaches to secure the communication.

Towards the security issues in Mobile Ad Hoc Networks
Mobile Ad hoc Networks (MANETs) are wireless networks consisted of mobile free nodes that can move anywhere at any time without the need to any fixed infrastructure or any centralized administration. In this category of networks existing nodes must rely on each other to play the role of routers or switches instead of using central ones. The self-organized nature of such environments made MANETs vulnerable against many security threats. As a result, providing security requirements in MANETs is one of the most interesting challenges in such a network. In this group of networks, the use of cryptographic solutions is one of the most interesting security issues. The importance of this scientific area in MANETs is more drastic by considering that mentioned schemes must be lightweight enough to be appropriate for resource constrained platforms in such environment. This paper has tried to represent the position of cryptographic issues in MANETs. Moreover, security issues in mobile Ad hoc networks beside of different classes of public key cryptosystems have been introduced.

On Recent Security Enhancements to Autoconfiguration Protocols for MANETs Real Threats and Requirements
2009
In the context of Mobile Ad hoc Networks (MANETs) security, most of research so far has been focused primarily on trust models and routing security problems, and much less attention has been given to the autoconfiguration security issue. However, the lack of security in the design of all previously proposed autoconfiguration schemes opens the possibility of many real threats, due to the well-known MANETs' vulnerabilities which are specific to ad hoc paradigm. This can lead hence to serious attacks in potentially hostile environments, such as IP Spoofing Attack, Exhaustion Address Space Attack, Conflict Address Attack, Sybil Attack, etc. Few papers have tackled this problem without however bringing satisfactory solutions. In this paper, we first present a survey of these approaches, and discuss their limitations. Then, we define the imperative security requirements in designing and implementing any solutions addressing this still open issue.

Security: A Core Issue in Mobile Ad hoc Networks
Computation is spanning from PC to Mobile devices. The Mobile Ad hoc Networks (MANETs) are optimal choice to accommodate this growing trend but there is a problem, security is the core issue. MANETs rely on wireless links for communication. Wireless networks are considered more exposed to security attacks as compared to wired networks, especially; MANETs are the soft target due to vulnerable in nature. Lack of infrastructure, open peer to peer connectivity, shared wireless medium, dynamic topology and scalability are the key characteristic of MANETs which make them ideal for security attacks. In this paper, we shall discuss in detail, what does security mean, why MANETs are more susceptible to security attacks than wired networks, taxonomy of network attacks and layer wise analysis of network attacks. Finally, we shall propose solutions to meet the security challenges, according to our framed security criteria.
Security threats in mobile ad hoc network
University essay from …, 2007
Mobile Ad Hoc Network (MANET) is a collection of communication devices or nodes that wish to communicate without any fixed infrastructure and pre-determined organization of available links. The nodes in MANET themselves are responsible for dynamically discovering other nodes to communicate. Although the ongoing trend is to adopt ad hoc networks for commercial uses due to their certain unique properties, the main challenge is the vulnerability to security attacks. A number of challenges like open peer-to-peer network architecture, stringent resource constraints, shared wireless medium, dynamic network topology etc. are posed in MANET. As MANET is quickly spreading for the property of its capability in forming temporary network without the aid of any established infrastructure or centralized administration, security challenges has become a primary concern to provide secure communication. In this thesis, we identify the existent security threats an ad hoc network faces, the security services required to be achieved and the countermeasures for attacks in each layer. To accomplish our goal, we have done literature survey in gathering information related to various types of attacks and solutions, as well as we have made comparative study to address the threats in different layers. Finally, we have identified the challenges and proposed solutions to overcome them. In our study, we have found that necessity of secure routing protocol is still a burning question. There is no general algorithm that suits well against the most commonly known attacks such as wormhole, rushing attack etc. In conclusion, we focus on the findings and future works which may be interesting for the researchers like robust key management, trust based systems, data security in different layer etc. However, in short, we can say that the complete security solution requires the prevention, detection and reaction mechanisms applied in MANET.

Security in mobile ad hoc networks: challenges and solutions
IEEE Wireless Communications, 2004
Security has become a primary concern in order to provide protected communication between mobile nodes in a hostile environment. Unlike the wireline networks, the unique characteristics of mobile ad hoc networks pose a number of nontrivial challenges to security design, such as open peer-to-peer network architecture, shared wireless medium, stringent resource constraints, and highly dynamic network topology. These challenges clearly make a case for building multifence security solutions that achieve both broad protection and desirable network performance. In this article we focus on the fundamental security problem of protecting the multihop network connectivity between mobile nodes in a MANET. We identify the security issues related to this problem, discuss the challenges to security design, and review the state-of-the-art security proposals that protect the MANET link-and network-layer operations of delivering packets over the multihop wireless channel. The complete security solution should span both layers, and encompass all three security components of prevention, detection, and reaction. 1536-1284/04/$20.00 © 2004 IEEE Broadcast [[REP,S,CERTd,Ns,t]Kdt]Kd-]Ka-],CERTa

Assessment of Security in Mobile Ad-Hoc Networks (Manet)
Journal of Global Research in Computer Sciences, 2011
With the proliferation of cheaper, smaller, and more powerful mobile devices, mobile ad hoc networks (MANETs) have become one of the fastest growing areas of research. This new type of self-organizing network combines wireless communication with a high degree node mobility. Unlike conventional wired networks they have no fixed infrastructure (base stations, centralized management points and the like). Mobile ad hoc networks (MANETs) are one of the fastest growing areas of research. Conventional networks use dedicated nodes to carry out basic functions like packet forwarding, routing, and network management. In ad hoc networks these are carried out collaboratively by all available nodes. In this paper, we’ll discuss about the MANET specific attacks, security challenges, goals and protocols alongwith the techniques used to secure MANETs.
