Stealth Attacks on Ad-Hoc Wireless Networks
نویسندگان
چکیده
We study two classes of attacks that can be mounted by manipulation of routing information and exhaustive power consumption. Our attacks allow an attacker to partition a network, reduce its goodput, hi-jack and filter traffic from and to victim nodes, and thereby eavesdrop and perform traffic analysis. The methods described are ”stealth attacks” in that they minimize the cost to and visibility of the attacker. We introduce the notion of reputation based control, and suggest that it can be used to augment existing routing protocols in order to immunize these against stealth attacks.

A New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
متن کاملA Survey of Solutions to Protect Against All Types of Attacks in Mobile Ad Hoc Networks
In recent years mobile networks have expanded dramatically, compared with other wireless networks. Routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. In this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...

Mobile ad hoc networks are networks composed of wireless devices to create a network with the ability for self-organization. These networks are designed as a new generation of computer networks to satisfy some specific requirements and with features different from wired networks. These networks have no fixed communication infrastructure and for communication with other nodes the intermediate no...

A wireless ad hoc network typically refers to any set of wireless networks where all devices have equal status on a network and are free to associate with any other wireless ad hoc network devices in their range. As the nature of these networks, they commonly do not have external power supplies, and each node has a limited internal power source. In this paper, we put forward a new routing proto...
متن کاملBroadcast Routing in Wireless Ad-Hoc Networks: A Particle Swarm optimization Approach
While routing in multi-hop packet radio networks (static Ad-hoc wireless networks), it is crucial to minimize power consumption since nodes are powered by batteries of limited capacity and it is expensive to recharge the device. This paper studies the problem of broadcast routing in radio networks. Given a network with an identified source node, any broadcast routing is considered as a directed...
