چکیده

Mobile Ad-hoc networks (MANETs) are inherently prone to security attacks, with node mobility being the primary cause in allowing security breaches. This makes the network susceptible to Byzantyne faults with packets getting misrouted or dropped. This paper proposes solutions using an unobtrusive monitoring technique to locate malicious or faulty nodes that misroute or drop packets. This technique uses information from different network layers to detect malicious nodes. Any single node can use unobtrusive monitoring without relying on the cooperation of other nodes, making this technique easy to implement and deploy. Simulations of MANETs containing malicious nodes indicate that this technique has a high detection effectiveness with low false positive rate.

A two-phase wormhole attack detection scheme in MANETs

Mobile ad-hoc networks (MANETs) have no fixed infrastructure, so all network operations such as routing and packet forwarding are done by the nodes themselves. However, almost all common existing routing protocols basically focus on performance measures regardless of security issues. Since these protocols consider all nodes to be trustworthy, they are prone to serious security threats. Wormhole...

Defending against Collaborative Packet Drop Attacks on MANETs

Detecting packet drop attacks is important for security of MANETs and current random audit based mechanism cannot detect collaborative attacks. In this paper, we design a hash function based method to generate node behavioral proofs that contain information from both data traffic and forwarding paths. The new method is robust against collaborative attacks described in the paper and it introduce...

A Distributed Trust and Reputation Framework for Mobile Ad Hoc Networks

In a multi-hop mobile ad hoc network (MANET), mobile nodes cooperate to form a network without using any infrastructure such as access points or base stations. The mobility of the nodes and the fundamentally limited capacity of the wireless medium, together with wireless transmission effects such as attenuation, multi-path propagation, and interference combine to create significant challenges f...

A Novel Intrusion Detection System for Detecting Black-hole Nodes in Manets

Mobile ad-hoc networks (MANETs) are autonomous,infrastructure less, self-organized networks. In MANETs, nodes are not stationary and thus move arbitrarily, resulting in rapid and unpredictable topology changes in the network. Due to the limited transmission range of the nodes in the MANETs, these nodes are not capable of directly communicating with each other. Hence, routing paths in MANETs pot...
