Security in Ad hoc Network through Intrusion Detection Techniques

Ad hoc networks are a new wireless networking paradigm for mobile hosts. Not like traditional mobile wireless networks, ad hoc networks do not depend on any fixed infrastructure. Rather, hosts depend on one another to keep the network associated. Security is the main concern in ad-hoc networks. Owe to the vulnerable nature of the mobile ad hoc network, there are various security threats that upset its improvement. There examine the fundamental vulnerabilities in the mobile ad hoc networks, which have made it a lot simpler to experience the effects of attacks than the conventional wired system. At that point examine the security criteria of the mobile ad hoc network and present the primary attack types that exist in it. At long last study the present security solutions through Intrusion Detection Technique for the mobile ad hoc network. There are two technique cluster based Intrusion Detection Technique for the mobile ad hoc network and misbehaviour Detection through Cross-layer Analysis are described

A Lightweight and Attack Resistant Authenticated Routing Protocol for Mobile Adhoc Networks

In mobile ad hoc networks, by attacking the corresponding routing protocol, an attacker can easily disturb the operations of the network. For ad hoc networks, till now many secured routing protocols have been proposed which contains some disadvantages. Therefore security in ad hoc networks is a controversial area till now. In this paper, we proposed a Lightweight and Attack Resistant Authenticated Routing Protocol (LARARP) for mobile ad hoc networks. For the route discovery attacks in MANET routing protocols, our protocol gives an effective security. It supports the node to drop the invalid packets earlier by detecting the malicious nodes quickly by verifying the digital signatures of all the intermediate nodes. It punishes the misbehaving nodes by decrementing a credit counter and rewards the well behaving nodes by incrementing the credit counter. Thus it prevents uncompromised nodes from attacking the routes with malicious or compromised nodes. It is also used to prevent the denial-of-service (DoS) attacks. The efficiency and effectiveness of LARARP are verified through the detailed simulation studies.Comment: 14 Pages, IJWM

A Study on Enhancement of the Security of the Routing Protocols in Adhoc Networks

An ad hoc wireless network is a set of wireless mobile nodes that self-configure to build a network without the requirement for any reputable infrastructure or backbone. Mobile nodes are utilized by the Ad hoc networks to facilitate effective communication beyond the wireless transmission range. As ad hoc networks do not impose any fixed infrastructure, it becomes very tough to handle network services with the available routing approaches, and this creates a number of problems in ensuring the security of the communication. Majority of the existing ad hoc protocols that deal with security issues depends on implicit trust relationships to route packets among participating nodes. The general security objectives like authentication, confidentiality, integrity,availability and nonrepudiation should not be compromised in any circumstances. Thus, security in ad hoc networks becomes an active area of research in the field of networking. There are various techniques available in the literature for providing security to the ad hoc networks. This paper focuses on analyzing the various routing protocols available in the literature for ad hoc network environment and its applications in security mechanisms

Layered security design for mobile ad hoc networks

When security of a given network architecture is not properly designed from the beginning, it is difficult to preserve confidentiality, authenticity, integrity and non-repudiation in practical networks. Unlike traditional mobile wireless networks, ad hoc networks rely on individual nodes to keep all the necessary interconnections alive. In this article we investigate the principal security issues for protecting mobile ad hoc networks at the data link and network layers. The security requirements for these two layers are identified and the design criteria for creating secure ad hoc networks using multiple lines of defense against malicious attacks are discussed

A secure and lightweight ad-hoc routing algorithm for personal networks

Over the past few years, there has been increasing interest in utilizing Personal Area Networks (PANs) to offer users innovative and personalized services. This interest is a consequence of the widespread use of mobile devices such as laptops, mobile phones, PDAs, digital cameras, wireless headsets, etc. to carry out a variety of user-centric tasks. The PAN itself is built upon an ad-hoc network where devices trust their neighbors to route their packets. The cooperative nature of ad-hoc networks allows malicious nodes to easily cripple the network by inserting false route information, replaying old messages, modifying messages of other nodes, etc. An applicable area still under research, and the focus of this paper, is secure routing protocols for ad-hoc networks. To achieve availability in the PAN, the routing protocol used must be robust against both dynamically changing topology and malicious attacks. However, the heterogeneous nature of Personal Network (PN) devices means that traditional security mechanisms are too resource intensive to be sufficient by themselves. This paper describes a new ad-hoc secure routing protocol for Personal Networks (PNs), suitable in a limited multi-hop scenario. This protocol is based on ADOV and relies on efficient cryptographic primitives to safeguard the security and privacy of PN users. Following that, a number of attacks in the area of ad-hoc networks are discussed, and it is shown that the new algorithm protects against multiple un-coordinated active attackers, in spite of compromised nodes in the network

Mobile Ad-Hoc Networks

Being infrastructure-less and without central administration control, wireless ad-hoc networking is playing a more and more important role in extending the coverage of traditional wireless infrastructure (cellular networks, wireless LAN, etc). This book includes state-of the-art techniques and solutions for wireless ad-hoc networks. It focuses on the following topics in ad-hoc networks: vehicular ad-hoc networks, security and caching, TCP in ad-hoc networks and emerging applications. It is targeted to provide network engineers and researchers with design guidelines for large scale wireless ad hoc networks
