Mobile Ad-Hoc Networks Security

Lecture Notes in Electrical Engineering, 2012

Mobile ad hoc networks (MANET) are becoming increasingly popular wireless networking model in various areas of technology usage from everyday to specific military purposes. Security in ad hoc networks is a key concern in order to provide protected communication between mobile nodes in an unknown and heterogeneous environment. The main challenge of MANETs is their vulnerability to security attacks and how to operate securely and efficiently while preserving its own resources. This paper discuss the most common type of attack on MANET and their security challenges. There are a lot of existing solutions in this field which propose increasing of MANETs security by new protocol design, evaluate existing protocols and their abilities, propose new routing protocols, find solutions and prevention measures for existing attacks or improving specific characteristics of MANET such as the packet drop rate, the overhead, end-to-end packet delays, network throughput etc.This paper attempts to provide an overview of MANET security challenges The paper finishing by presenting current and possible solutions as a problems requiring for further research in the fuure.

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 Issues in Mobile Ad-Hoc Networks 1

In this survey paper we have studied about different Mobile Adhoc networks in the infrastructure less wireless network. In a network the mobile nodes move rapidly from one node to the another. The application of MANET requires very good efficient group communication for the data transfer. The security constraints taking place in the MANET is very low when compared to the wired network. This survey paper is discussing not only the the different Mobile Ad-hoc networks, but also about the different attacks in the MANET layers. These attacks in the MANET layers are may be active or passive. The passive attacks does not alter by the attacker. The main focus of the active attacks is on the network layer protocols.

Security Aspects in Mobile Ad Hoc Network (MANETs): Technical Review

International Journal of Computer Applications, 2010

Mobile Ad hoc networks (MANETs) are a new paradigm of wireless network, offering unrestricted mobility without any underlying infrastructure such as base station or mobile switching centers. Basically ad hoc network is a collection of nodes communicating with each other by forming a multi-hop network. In a mobile ad hoc network, it is much more vulnerable to attacks than a wired network due to its limited physical security, dynamically changing network topology, energy constrained operations and lack of centralized administration. Since all the nodes in the network collaborate to forward the data, the wireless channel is prone to active and passive attacks by malicious nodes, such as Denial of Service (DoS), eavesdropping, spoofing, etc. The intent of this paper is to investigate the security goal, security challenges and different types of active and passive attacks on MANETs.

Security Issues in Mobile Ad Hoc Network

Signals and Communication Technology, 2013

Mobile Ad hoc Networks (MANET) are infrastructure-less networks characterized by lack of prior configuration and the hostile environments. Their unique properties make them a natural candidate for situations where unplanned network establishment is required. However this flexibility leads to a number of security challenges. Security in MANET is a very complex job and requires considerations on the issues spanning across all the layers of communication stack. This chapter reviews the security problem in MANET. It provides an updated account of the security solutions for MANET with detailed discussions on secure routing, intrusion detection system and key management problems. The chapter is concluded with a comprehensive security solution for MANET.

A Literature Review of Security Attack in Mobile Ad-hoc Networks

International Journal of Computer Applications, 2010

Security is a major concern for protected communication between mobile nodes in a hostile environment. In hostile environments adversaries can bunch active and passive attacks against intercept able routing in embed in routing message and data packets. In this paper, we focus on fundamental security attacks in Mobile adhoc networks. MANET has no clear line of defense, so, it is accessible to both legitimate network users and malicious attackers. In the presence of malicious nodes, one of the main challenges in MANET is to design the robust security solution that can protect MANET from various routing attacks. However, these solution are not suitable for MANET resource constraints, i.e., limited bandwidth and battery power, because they introduce heavy traffic load to exchange and verifying keys. MANET can operate in isolation or in coordination with a wired infrastructure, often through a gateway node participating in both networks for traffic relay. This flexibility, along with their selforganizing capabilities, are some of MANET's biggest strengths, as well as their biggest security weaknesses. In this paper different routing attacks, such as active(flooding, black hole, spoofing, wormhole) and passive(eavesdropping, traffic monitoring, traffic analysis) are described.

Security Challenges in Mobile Ad Hoc Networks: A Survey

International Journal of Computer Science & Engineering Survey, 2015

MANET is a kind of Ad Hoc network with mobile, wireless nodes. Because of its special characteristics like dynamic topology, hop-by-hop communications and easy and quick setup, MANET faced lots of challenges allegorically routing, security and clustering. The security challenges arise due to MANET's selfconfiguration and self-maintenance capabilities. In this paper, we present an elaborate view of issues in MANET security. Based on MANET's special characteristics, we define three security parameters for MANET. In addition we divided MANET security into two different aspects and discussed each one in details. A comprehensive analysis in security aspects of MANET and defeating approaches is presented. In addition, defeating approaches against attacks have been evaluated in some important metrics. After analyses and evaluations, future scopes of work have been presented.
